Scam ID & Scam Block

Easily identify and block calls from likely scammers with Scam ID and Scam Block.




Scam ID and Scam Block are free of charge with your T-Mobile postpaid plan. Scam ID displays "Scam Likely" on your screen when calls come in from likely scammers on both smartphones and feature phones. Scam Block allows you to block Scam Likely calls. You can turn them on or off at any time. And now, network level protection has been added to stop the increasingly common “Neighborhood Spoofing” and prevent hijacked numbers (where scammers temporarily match the area code and 3-digit prefix of the person they are targeting) from reaching your phone.


Help us improve these services by reporting an improperly identified call.

Anonymous callers

The FCC mandates that mobile carriers allow callers the ability to block their caller ID information and place anonymous calls. T-Mobile is obligated to honor the privacy of the caller in these circumstances. T-Mobile can't block anonymous calls or override the privacy choice of the caller, but you may choose not to accept them. To make an anonymous call yourself, dial *67 before dialing the number you are calling.
