What is Truecaller?
Truecaller is a caller ID and spam-blocking app for Android and iOS, developed by Truecaller AB in Sweden. It identifies incoming calls and flags likely spam using a database built partly from its community of users, who can tag and report numbers. The app also offers call blocking and messaging features. The basic app is free with ads, and a paid Premium subscription adds extra features. Truecaller also has a web search on its website, which asks you to sign in before showing results. Its privacy policy describes the data it processes, including contact information in some cases, and it offers a way for people to unlist their own number.
Why people look for a Truecaller alternative
- You want to check a single number without installing an app on your phone.
- The Truecaller website asks you to sign in before it shows a search result.
- You prefer not to grant an app access to your contacts or call log; Truecaller's privacy policy explains what it collects and when.
- Some features sit behind a Premium subscription, and you only need an occasional lookup.
- You are on a computer and want to look up a number there.

Our verdict
If you want every incoming call identified automatically and spam blocked before you answer, Truecaller is the better fit, because a website cannot screen calls on your phone in real time. If you just want to check a number now and then, without installing an app or sharing access to your phone, WhoCallsMe gives you the carrier, line type, region and spam reports in your browser for free, with an optional full report when you need more.
