Anonymous Callers

Blocking Anonymous Callers

When you use T-Mobile communications services to receive calls, the telephone number of the calling party is generally delivered to your mobile device, allowing you to identify the number (and the name you may have entered into your contacts) of a caller before answering. However, the FCC has mandated that carriers allow callers the ability to block their Caller ID information and thus place “anonymous” calls. T-Mobile is obligated to honor the privacy of the caller in these circumstances. Of course, you may choose not to accept such calls. But we cannot block the call or override the privacy choice of the caller. 

Similarly, when you make a call from a T-Mobile device, you may choose to block your Caller-ID information, which you can generally do by dialing *67 prior to dialing the called party’s number. Refer to the specific instructions for your communication device regarding Caller ID Blocking for other or different dialing instructions. Please note, however, that Caller ID Blocking does not prevent the display of your information when you dial certain business numbers, including 911, 900 numbers, or toll-free numbers. For more specific information or instructions, you may reach a customer service representative by dialing 611 from your T-Mobile phone or 1-800-937-8997 from any phone.
