TrustCaller: Block Spam Calls Live

Stop spam calls before your phone even rings. TrustCaller screens every incoming call against a constantly updated spam database and blocks known scammers, robocallers, and telemarketers automatically. No account. No sign-up. Just turn it on. ■ AUTOMATIC CALL BLOCKING Known spam numbers are rejected before your phone rings. You never hear from them, and you can see exactly what was blocked in your activity log. ■ CALLER ID FOR UNKNOWN NUMBERS When an unrecognized number calls, TrustCaller tells you who it is — "Spam Risk," "Telemarketer," or a verified business name — so you know whether to pick up. ■ REVERSE PHONE NUMBER LOOKUP Got a missed call? Search any number to see its risk level, how many people have reported it, and whether it's safe to call back. ■ REPORT SPAM AND SCAM CALLERS Report spam, scams, robocalls, and harassment in two taps. Your reports feed the shared database and protect everyone else using TrustCaller. ■ POWERED BY REAL COMPLAINT DATA Our spam database is built from user reports plus daily Do Not Call complaint data filed with the Federal Trade Commission — tens of thousands of real, verified spam numbers, refreshed automatically in the background. ■ DO NOT CALL REGISTRY TOOLS Check whether your number is on the FTC Do Not Call Registry, register it for free, and file complaints against callers who ignore it. ■ BUILT FOR PRIVACY TrustCaller checks callers against a spam database stored on your device. It doesn't upload your contacts, doesn't read your messages, and doesn't need an account. Your lookup history stays on your phone. ■ TRUSTCALLER PLUS Upgrade for real-time caller ID: numbers that aren't in the on-device database yet get looked up the instant your phone rings, instead of waiting for the next database refresh. Plus also removes all ads and helps fund the spam database that keeps the core app free. TrustCaller is free, supported by ads. No account required. We never sell your data.
