T-Mobile is fighting back against scam calls with 100% STIR/SHAKEN compliance

STIR/SHAKEN – What to know

BELLEVUE, Wash. — June 30, 2021 — T-Mobile (NASDAQ: TMUS) today announced that it has filed a certification of completion of STIR/SHAKEN implementation in the Federal Communications Commission’s Robocall Mitigation Database. With the filing, the Un-carrier is certifying that all calls originating on the T-Mobile network are 100% STIR/SHAKEN compliant.


T-Mobile was the first US wireless provider to work with all other major networks to implement STIR/SHAKEN to fight number spoofing and further protect customers from scammers. With these partnerships, T-Mobile authenticates calls with wireless and network providers that collectively represent around 98% of wireless customers in the U.S.

Number Verification provided by STIR/SHAKEN, coupled with free Caller ID provided by T-Mobile Scam Shield, helps T-Mobile customers rest assured that the calls they receive are authenticated as coming from the phone number displayed in Caller ID and have not been spoofed. This makes Caller ID even stronger in the fight against scam and robocalls, and with Scam Shield, all T-Mobile, Metro by T-Mobile and Sprint brand individuals, families and small business get free Caller ID.

T-Mobile currently provides STIR/SHAKEN implementations with AT&T, Comcast, Spectrum Voice from Charter Communications, UScellular, and Verizon Wireless as well as Altice USA, Bandwidth, Brightlink, Clear Rate, Google Fi, Inteliquent, Intrado, Magicjack, Peerless, and Twilio.

What you need to know

  • Calls originating on the T-Mobile network are 100% STIR/SHAKEN compliant.
  • T-Mobile has implemented STIR/SHAKEN with 15 other carriers.
  • STIR/SHAKEN works with T-Mobile’s Caller ID to make sure the displayed number is accurate.

Scam and spam calls can often come from a number that looks familiar or spoofs another trusted number, so a traditional caller ID may not be effective against these calls. STIR/SHAKEN works to verify that a call is coming from the claimed source.

John Freier, Executive Vice President of T-Mobile Consumer Group, said:

Number Verification, along with Caller ID, and the scam identification and blocking tools in Scam Shield, gives our customers the industry’s most comprehensive free scam and spam protection.

We were first to implement number verification in 2019 and today, all calls originating on the T-Mobile network are 100% STIR/SHAKEN compliant, giving our customers peace of mind that their calls are protected against scammers and spammers.

STIR/SHAKEN (Secure Telephone Identity Revisited and Signature-based Handling of Asserted Information Using toKENs) is a method of verifying that phone calls made over IP are actually coming from the proper origin by having the caller ID signed by the originating carrier. Calls made over IP are routed over an internet protocol and are required by the FCC for STIR/SHAKEN. This method is now being used by every major carrier, including T-Mobile, as it increases its reliance on 5G coverage, which uses IP for calls.
