Spam calls are a nuisance that most of us have to deal with on a regular basis. With scammers constantly finding new ways to get through to your phone, it can feel impossible to avoid them.

Thankfully, Truecaller offers some incredibly effective tools to block spam calls and text messages. In this post, I’ll explain exactly how to stop spam on Truecaller.

How Truecaller’s Spam Blocking Works

Truecaller uses a constantly updating database of known spam numbers, flagged by their millions of users around the world.

Whenever you receive a call or text, Truecaller checks the number against this database. If it finds a match, the caller will be flagged as “spam risk” or “verified spam“.

The app also uses advanced filtering technology to identify potential spammers based on calling patterns and behavior.

For example, if a number makes sequential calls to many users in a short time, or frequently changes IDs, Truecaller will recognize it as spam.

Once a number is flagged, you have the option to block it directly in the Truecaller app. Over time, this blocks the vast majority of spam calls and texts from ever reaching your phone.

Stop Spam Calls with Call Blocking

One of Truecaller’s most popular features is the ability to completely block calls from known spammers and untrusted numbers. Here’s how to enable call blocking:

  1. Open the Truecaller app and go to Settings.
  2. Tap on Block.
  3. Enable the following options.
    • Block top spammers
    • Block hidden numbers
    • Block numbers from foreign countries
    • Block numbers not in the phonebook.

You can choose the option to disable also, if you want foreign numbers or calls from contacts outside the phonebook.

Now all calls from suspected spam numbers will be automatically blocked. Your phone won’t ring and you won’t get interrupted.

You can also block specific numbers manually by tapping the “Block” button on any Truecaller caller ID screen. This is useful for blocking numbers not already flagged in their database.

Fix Issues with Truecaller’s Spam Blocking

While Truecaller’s spam blocking is generally very accurate, issues can occasionally come up. Here are some common problems and how to fix them:

Problem: Truecaller isn’t identifying some spam calls.

Solution: Make sure to report missed spam calls in the app. This helps Truecaller identify new spam numbers.

Problem: Truecaller is blocking wanted calls.

Solution: Whitelist important contacts in the app settings. This overrides the spam blocking for their numbers.

Problem: Spam blocking filter isn’t working properly.

Solution: Try restarting your device and the Truecaller app. Check for app updates. Re-enable permissions.

Problem: Spam calls are still coming through.

Solution: Confirm that spam blocking is enabled in the app settings. Consider using Caller ID or Premium features for more aggressive blocking.

Problem: Truecaller isn’t blocking text message spam.

Solution: Enable the “Block spam SMS” option in app settings. This stops spam texts just like calls.

Taking a couple minutes to report spam callers and tweak your Truecaller blocking settings can make a huge difference. Over time, you’ll notice far fewer unwanted calls and texts coming through.

Identify Spam and Fraud Calls

In addition to blocking, Truecaller Premium uses crowd-sourced reports and phone number analytics to identify high-risk callers. Whenever you receive a call, Truecaller will display the name, location, user comments and more.

This makes it easy to identify potential spam calls before answering. Here are some telltale signs of a spammer:

  • Flagged as spam risk or verified spam: Truecaller has identified the number as a known source of spam calls.
  • No name or location info: Anonymous callers are more likely to be scammers.
  • Short, generic label: Names like “Service”, “Credit Card”, etc. often indicate spam.
  • Multiple user complaints: See user comments warning about spam or fraud.
  • Sequential calling pattern: The number has called multiple users in a short period.
  • Frequent ID changes: The caller regularly spoofs different numbers.

Using Truecaller’s enhanced caller ID and community feedback helps you detect spammers before becoming their next victim.

Manually Mark Numbers as Spam

As much as Truecaller tries to identify spammers automatically, you’ll inevitably encounter some numbers it doesn’t recognize. By manually reporting these calls, you help improve Truecaller’s spam detection for all users.

Here are two ways to mark a number as spam in Truecaller:

During an incoming call: If you suspect a call is spam, simply tap “Spam” on the caller ID screen. This immediately blocks the number while reporting it.

After a call: Open your call history in Truecaller, find the call and tap “Mark as spam”. This helps Truecaller identify new sources of spam.

You can also flag messages as spam to block future texts from the number. With the whole Truecaller community reporting spam, the database stays highly accurate and up-to-date.

Even with diligent spam blocking, the occasional unwanted caller might slip through. Here are some tips to further reduce unwanted calls:

  • Consider adding spam monitoring apps like Mr. Number to supplement Truecaller’s blocking with new sources of spam reports.

Catching and reporting additional spam calls makes Truecaller’s service even more effective at stopping them in the future.
