If you need to assign a Power of Attorney to your T-Mobile account, here's what you'll need to know. A Power of Attorney (POA) is a legal document that gives another person authority to act on your behalf. By adding a POA to your T-Mobile account, you are giving us permission to treat your POA as the account holder, also known as the Billing Responsible Party (BRP). To learn more about what permissions that includes, check out Billing Responsible Party.

• Official POA.
• Submit a completed T-Mobile Power of Attorney Form online or by mail using the form located in Attachments.
