Scam ID and Scam Block automatically displays "Scam Likely" and the number that is calling on suspected scam calls. Scam ID also catches spoofed calls because T-Mobile looks beyond the incoming number and tracks actual call behavior. Scam Block automatically blocks all "Scam Likely" calls before they ever reach your phone, so you never even see them. 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.

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.

Number Verified enhancement (STIR/SHAKEN)
- New FCC standards of STIR (Secure Telephony Identity Revisited) and SHAKEN (Secure Handling of Asserted information using toKENs) have been adapted to help fight scam callers industry-wide. T-Mobile’s implementation of these standards is known as “Number Verified.”
- As of January 7, 2019, T-Mobile was first to introduce Number Verified Enhancement between customers, a STIR/SHAKEN technology aimed at reducing spoofed calls to customers.
- If you have a Number Verified enabled device, you will see "Number Verified", “Caller Verified”, or “T-Mobile Verified” in caller ID or a checkmark in the call log on the phone screen when you receive a call that has been verified as authentic, not spoofed.
- Calls marked as verified have an on-screen display when a call has been verified. Non-verified calls or calls from customers of other mobile carriers continue to come in as not verified.
- T-Mobile is working with our phone manufacturers to provide customers with as much protection as possible, free of charge.
