How to block unknown numbers on android

We all get pesky robocalls from unknown numbers. Marketers are bombarding consumers continuously, no matter how many call centers are shut down. Fortunately, there is a way to block them on Android and iOS.

Note that unknown numbers are different from private ones when the caller ID is withheld. In the first case, you can identify the service provider and location. Blocking is also relatively easy.

If You Have an Android Phone

Your phone can detect unknown numbers and block them automatically. Alternatively, you may send particular callers to your blacklist. Here is what to do after receiving an unwanted call:

  1. Open your Phone app and find the number;
  2. Click on the “I” button on the right;
  3. Tap on the tree-dot menu at the bottom left;
  4. Select “Block contact”.

That’s all! Now, your smartphone will automatically reject all calls from this number. You will not hear it ring, and there won’t be any notifications. Yet, the calls will appear on your list marked as blocked.

Try an App

Google Play has plenty of apps for different identification tasks, including blocking. Their features are quite broad. For example, you may limit your blacklist to private numbers, unknown numbers, spam text, and more. If you are not satisfied with the default features of your smartphone, get an app to enhance the protection.

If You Have a Samsung Galaxy Phone

On Samsung Galaxy, blocking numbers of telemarketers and scammers is a breeze. The system allows you to reject any calls from private numbers, or limit the band to particular colors. Here is what you should do:

  1. Open the Phone app;
  2. Tap the three-dot button in the upper right corner;
  3. Choose “Settings”;
  4. Choose “Block numbers”;
  5. “Block unknown callers” for blanket blocking — tap and slide to the right. Alternatively, enter an individual number in “Add phone number” and tap “+” on the right.

Tip: you do not have to enter the number manually — just copy it from the Phone app, tap in the “Add phone number” field, and paste. To copy the number from your list of calls, you should open the “Recents” tab, find the call, and tap the “I” on the right.

If You Have an iPhone

Users of iOS 13 have two options — a blanket ban on unknown numbers or separate blacklisting. These options are built into the operating system. This eliminates the need for third-party apps.

Now, Siri’s intelligence is used to determine if calls come from the callers you have previously interacted with. This includes your Contacts, Mail, and Messages. You do not even have to save their numbers! All other calls will be automatically sent to voicemail. Here is what to do:

  1. Open the Settings app;
  2. Find the “Call silencing and blocked contacts” feature at the bottom;
  3. Activate “Silence Unknown Callers”.

Naturally, this method is not ideal, as you may need to receive calls from potential employers or delivery companies. However, if you are sick and tired of robocalls, this should give you peace of mind. If you want to be selective and block a particular number, do the following:

  1. Open the Phone app;
  2. Go to “Recents”;
  3. Find the number and tap the “i”;
  4. Tap “Block This Caller” (at the bottom).

Block Calls from Private Numbers

Both Android and iOS will let you reject calls from private numbers as well. In either system, the setting is far from perfect, as it is only a blanket ban. Therefore, any friend or family member who uses a withheld number will be blocked automatically. This is done on the handset, not the network, so there is no way to circumvent this drawback.

Why You Cannot Block Separately

Callers who want to hide their numbers use *67. This causes their smartphones to send a special request to the network. The caller ID is concealed at the final point — when the call comes through. As it is not received by your phone, the system cannot identify the number attached to it. This is why a blanket band is the only solution.

Blocking Private Numbers on Android

  1. Open the Phone app;
  2. Tap the three dots at the top;
  3. Choose “Blocked”;
  4. Open “Call block rules”;
  5. Activate “Block private/withheld numbers”.

Blocking Private Numbers on iOS

Unfortunately for iPhone users, systems older than iOS 13 (see above) do not allow them to block private calls easily. First, they may adjust the settings for their Do Not Disturb mode, so only calls from their contacts are allowed. Secondly, they may use the “Block this caller” option from the Phone app for separate numbers.

Why Do Companies Use Robocalls?

In the US and globally, phone spam is on the rise. In the past few years, the number of calls made daily has skyrocketed. In 2019, Americans received 5 billion calls monthly!

At first glance, this seems counterintuitive. Why would anyone pay for such an old-fashioned way of promotion, which is also untargeted and grossly ineffective? After all, an overwhelming majority of people hang up as soon as they realize they have been called by a robot.

The answer is simple — economics. Automatic calls are extremely cheap to make. So cheap that getting a few leads is worth making thousands or millions of calls. Besides, even though these calls are technically illegal, the government has done little to regulate them.

Companies that use robocalls are usually scammers. They may sell something that does not exist. They may sell products of inferior quality. The technology allows them to reach thousands of people every minute. For example, according to NPR, Message Communications, Inc. sells 125,000 minutes of robocalls for $875. Considering the average length of a call, this translates into 2.5 million calls, which is definitely a bargain.

Final Tip

US citizens can add their numbers to the National Do Not Call registry. After 31 days, if you receive an unwanted call, you can report it. In this case, the caller will be penalized.

How to block unknown numbers on android

We hate robocalls and spam calls, and we know you do too.

Scammers flood our phones about expired warranties, overdue taxes to the IRS or irregular activity on a credit card. They are persistent, annoying and dangerous.

But we’re here to give you a few simple ways to help slow or stop the irritating and aggressive robocalls and spam calls that you might be getting on your phone.

If you’re getting these annoying spam calls to your phone, you’re not alone — and the problem is growing worse every year. In 2020 alone, the average American received more than 28 spams calls per month , a big increase over the year before, despite the pandemic.

There are some simple and free steps you can take to slow the onslaught of spam calls hitting you every day. In addition, a few paid apps can help to significantly try to reduce the robocalls and spam calls that you receive.

Register your phone number with the National Do Not Call list

In addition to some initial common sense steps to protect yourself from scammers, like not answering your phone from blocked numbers or numbers you don’t recognize and never giving out personal information to people you don’t trust, take a few minutes to register your phone number with the National Do Not Call Registry .

The Do Not Call Registry is an FTC initiative to stop unwanted telemarketing calls to landlines and mobile phones along with a mechanism to report bad actors. While this should reduce the number of calls you might receive from legitimate marketing campaigns, it won’t stop disreputable marketers or illegal scammers from dialing your number. You can also legally receive calls from pollsters, political organizations, charities and debt collectors, however we do think it’s a good first step for everyone to take.

Silence unknown numbers in iOS

If your Apple device is running iOS 13 or higher, you can silence all incoming calls to your phone that aren’t in your contact list and send them straight to voicemail. This won’t completely stop the calls coming in, but it will prevent your phone from ringing or vibrating from unwanted calls. Before turning this on, make sure important phone numbers are stored in your Contacts if you don’t want to miss an important call (never fear – they can still leave a message!).

To turn on Silence Unknown Callers , go to Settings > Phone, then scroll down, tap Silence Unknown Callers, and turn on the feature.

Block all unknown numbers in Android

If you have an Android device, you may be able to block all calls coming from unknown numbers. This is a little more extreme than silencing unknown callers, but if your phone is ringing off the hook, this could be a good option.

To turn on this feature (the instructions may vary from one Android device to another), Tap the phone icon > Tap the three dots at the top of the screen > Tap “Settings” in the dropdown menu > Tap “Block numbers” > Toggle the button beside “Block unknown callers.”

Block specific numbers on your phone

As robo or spam calls come in, you can block each phone number from calling you again. We’ll be honest, this is a game of whack-a-mole, since scammers use endless numbers — even spoof your number, a neighbor , or your bank’s phone number — to keep calling you, but it’s worth a shot if you want to slow these calls.

To block numbers on iOS , open the phone app, tap Recents, tap the Info button next to the phone number or contact that you want to block. Scroll down, then tap Block this Caller. Do this for every number that you want to block in the future.

To block numbers in Android (again, this will depend on the model of your phone), open the Phone app > Tap recent calls or call history > Tap the number you want to block > Find the command to block or report as spam.

Use a Third-Party Spam Call & Text Blocker

If all else fails — and it might — a third-party app to identify and block annoying robocalls, spam calls and texts is a great option.

These apps enhance the caller ID functions of your phone, employ large blacklists of spam numbers to automatically block calls and texts in real time, along with other call blocking features. Some apps are free with limited bells and whistles, while the paid apps have more robust features and customer service, which also comes with a monthly or yearly user fee.

Some popular spam blocking apps include Hiya: Caller ID & Spam Blocker (Free on iOS & Android ), Nomorobo ($1.99 per device, per month + a 14 day free trial), and RoboKiller: Spam Call Blocker ($39.99/yr + 7 day free trial).

Nowadays, people hardly use SMS to communicate. Instant messaging apps has overtaken traditional text messages. However, SMS is still useful regarding getting information and notifications. You get the verification codes for logging to your online account. You get your banking transactions notifications via text messages.

However, you also get messages from popular brands about their latest products. But when you start receiving promotional messages too much, it gets irritating. Every time your phone chimes, you check it if anything important comes and it turns out a promotional SMS. Here in this article, you will know how to block spam messages on your Android phone.

Block SMS using Android inbuilt Feature

Even Google knows that you are tired of receiving spam messages. That’s why they have included the Spam Filter in the inbuilt Messages app. You can enable the Spam Filter, and it will automatically filter the unwanted messages.

Tap on the three vertical dots in the Messages App and then tap on Settings. Choose the SIM card on which you want to enable the spam filter.

How to block unknown numbers on android

Now tap on Spam protection. Use the Toggle button to enable it. You can do the same for your other SIM card if you are using dual SIM on your phone.

Alternatively, if you want to block a particular sender, you can also do that. Long tap on the SMS thread and tap the Block icon. Now tap OK. The sender will be blocked, and you won’t receive text or calls anymore. The current thread will be archived.

How to block unknown numbers on android

You can also report the sender as a spammer. Google receive up to 10 last messages that you receive from the sender. Google will even get the number of the sender. It helps Google to understand the pattern of Spam messages, and then they apply it in their automatic spam filter which you enabled earlier. Don’t worry; Google will not receive the messages that you sent. Their last SMS could also go to your carrier; they might take action against the sender regarding spam. If you don’t want to report and block the sender, then deselect the option of Report as spam.

Use Third-Party Apps to Block Unwanted Texts

If you are not satisfied with the Android’s inbuilt spam filter, then you can check out third-party messaging apps. These apps work great in filtering the unwanted SMS and also has some great feature. I am listing four such third-party apps that are available in the Google Play store.

1. TrueCaller

TrueCaller is your best friend if you are fed with the promotional messages and calls. It automatically identifies the spam and promotional messages and blocks them. You can also get the ID of the unknown sender. It has an extensive database of numbers and name. If you are receiving a call from an unknown number, you get the caller ID, and if it is spam, it also shows the number of people reported the caller as spam.

How to block unknown numbers on android

TrueCaller also offers a few other features such as call recording, backup call history, and UPI Payment method. One thing to note that when you install TrueCaller, it uploads your phone book to its database. That’s the way it gets the proper ID of unknown callers. If you do not want some app to gain access to your phone book, then don’t install this app.

2. SMS Organizer from Microsoft

I use this app, and I am in love with it. The way it handles the SMS is impressive. It filters the spam and promotional messages automatically and moves them to the promotional folder. You won’t get any notifications when you receive an unwanted text. It shows notifications for transactional and personal messages and puts them in a separate folder. If any promotional messages get in the main folder, you can move it the promotional folder by swapping right. From the next time, you won’t see a text from that sender.

We often receive OTP for transactions and to view it; we had to open the message. But SMS Organizer directly shows the OTP in big fonts on your notification area. So you don’t have to open the SMS. You can also back up the texts in your Google Drive account. You have to link the drive account to enable it.

How to block unknown numbers on android

It fetches the information from SMS and shows you reminders of things like bill payment, upcoming train or flight journey, and other important stuff. The finance tab shows you the balance in your savings account and credit card limit. It pulls these details from the SMS so if you didn’t receive an SMS of a transaction then these details would not be accurate.

It can also automatically delete the promo messages, OTP messages, and blocked messages after a predefined time. This setting is disabled by default; you have to enable it by visiting Settings and Rules.

3. Key Messages

Another great way to avoid spam SMS is to use Key Messages. It automatically detects the promotional and spam messages and blocks them. It also organizes your messages in different tabs, so you can easily find them. You can prevent the SMS by name, number, content keyword, and wildcard rule. It also counts the characters and shows how many text messages are going to charge if send all those texts.

How to block unknown numbers on android

Key Messages also backs up your SMS to Google Drive. You can restore them to your new phone or current without any duplication. It also backs up the allow and blocked list. With the search option, you can search a message from the thousands of SMSes in your inbox.

4. Reos SMS

This app is much more like SMS Organizer from Microsoft. It categorizes your inbox into social and business messages. The app also shows OTPs in big font and gives you the status of train, cab, movie ticket bookings. It automatically blocks spam messages to keep your inbox clean.

How to block unknown numbers on android

Reos SMS also has the instant messaging feature which you can use to chat with your friends. Clean UI and UX is the specialty of this app. The only problem with this app is, it doesn’t show the blocked SMS. The SMS Organizer, on the other hand, displays the blocked SMS in another folder but Reos doesn’t show them.

You don’t need to use all these apps to block unwanted message on your Android device. Use one that is suitable for your need. If you receive few spam messages, then Android inbuilt messaging app is best for you. However, if you receive tons of spam messages, then I would recommend you to install SMS Organizer from Microsoft.

I get an average of 12 phone calls a day, and 75% of them are usually spam. It’s either a robot telling me about credit card debt I don’t have or a human asking me to buy something I don’t need. I assume, anyway, because of course I hardly ever answer a call I don’t recognise on my iPhone.

As for my Android phone, which is a Samsung Galaxy J8 (yes, two phones, work thing), I don’t have that problem, because I have the phone set to block all unknown numbers.

Here’s how to do the same on your Android.

What to Know

  • Even if you register your phone number in the National Do Not Call Registry, you are still likely to get some unwanted calls and texts.
  • Call-blocking apps like PrivacyStar use crowd-sourced databases to help you control calls and texts from specific numbers.
  • You can block specific numbers on iPhones on a case-by-case basis.

This article explains how to stop unwanted phone calls on smartphones (even from private numbers) and landlines as well as how to block malicious text messages on smartphones.

Information in this article applies to landlines, iPhones, and Android phones made by various manufacturers.

Android: Use an App to Block Junk Calls and Text Messages

While it’s possible to block numbers on Android phones, the process differs depending on the phone’s manufacturer. If you wish to block telemarketers and robocalls altogether, consider one of the many call-blocking apps that are available for Android.

One example is PrivacyStar, which is also available for iOS. PrivacyStar gives you control over calls and texts from specific numbers and those that are unknown or private. Its crowdsourced database of blocked numbers can expand your blocked list to include the worst offenders, and you can file complaints with the government for calls and text messages that are spam.

How to block unknown numbers on android

Call and text blocking for iOS aren’t available because of iPhone app restrictions. However, reverse phone lookup and complaint filing work fine.

iPhone: Silence Unknown Callers

You can block numbers on iPhones on a case-by-case basis. Another method is to create a Do Not Answer group in your contacts and set a specific or silent ringtone to ignore certain callers. For preemptively blocking unwanted callers, apps like RoboKiller can purportedly block 99 percent of spam calls.

Additionally, iOS 13 has a feature called Silence Unknown Callers. To enable this feature, go to Settings > Phone > Silence Unknown Callers. Any unknown numbers are sent to your voicemail and are visible in your list of recent calls.

Landlines: Block Specific and Unknown Numbers

If you have a landline phone number, you may have even more robust blocking capabilities. For example, you may be able to enter specific phone numbers you want to block permanently on your service provider’s website.

For example, Verizon has an option to block anonymous callers. However, it’s not very reliable since private numbers can still come through. If the robocalls don’t stop, contact your phone company with the numbers on hand to block those permanently.

How to Block Private Numbers

You have the option to block unknown callers when you set up Do Not Disturb on iPhone. If you have caller ID set up for your landline, you can usually block private numbers by dialing *77. You should hear a confirmation message. If a number shows up as Anonymous, Private Name, or Unknown, the caller receives a message saying that you are not taking unknown calls.

It’s also possible to block unknown numbers on most Android phones, although the process is different for each manufacturer. Tap the three-dot menu in the Phone app and choose Settings, then look for an option to block unknown callers. If your phone doesn’t have this option, use an app like PrivacyStar.

How to block unknown numbers on android

Google Pixel: Spam Call Blocking

Google Pixel phones have Call Screen enabled by default. So, when you get a call from an unknown number, Google Assistant answers for you. If the call is legitimate, your phone rings. However, if it’s a robocall, the call is dropped. You’ll receive a notification, and you can review the call in your call log.

Samsung: Smart Call

If you have a Samsung phone, it may have a feature called Smart Call depending on the model. Smart Call lets you know the identity of unknown callers. To turn on Smart Call, open the Phone app’s setting and enable Caller ID and spam protection.

Best Practices for Everyone

Unwanted and anonymous calls can be as much of a security risk as they are aggravating. Avoid the worst that could happen by dealing with these threats wisely:

  • Don’t respond to unwanted calls, even if the call prompts you to press a number to opt-out of future messages. All that does is verify to the scammer that your number is valid.
  • Don’t respond to unwanted text messages or follow any unsolicited links.
  • Register with the National Do Not Call Registry.
  • File a complaint with the FTC if you’ve been scammed by a robocall.
  • Avoid inputting your phone number in online or offline forms unless you absolutely must.

Burner is a great privacy app for iPhone and Android that provides disposable phone numbers to protect your privacy.

If you’re answer is yes, then there is an easy way to block calls in your android. There is no need for additional apps because most Android smartphones or tablets with the newer version Jellybean and upwards support call blocking via call settings. Here is how you can do that:
