Only the Billing Responsible Party (BRP) can add an authorized user on a consumer T-Mobile account, making it a straightforward process once you know the rules. To add authorized user T-Mobile access, you must be the primary account holder and the person being added must be at least 18 years old (21 in Puerto Rico).
What to know before you add an authorized user on T-Mobile
Before you begin, verify these eligibility rules to avoid delays. The person you add must be at least 18 years old, or 21 years old if the account is based in Puerto Rico. Only the Billing Responsible Party (BRP) can add or remove authorized users on consumer accounts. For Business and Government accounts, both the BRP and existing authorized users can add or remove authorized users. Prepaid accounts have different self-service options for managing users, so this process applies to postpaid accounts only. Each T-Mobile account can only have one Primary Account Holder (PAH), so the authorized user role is distinct from that ownership level.
How to add an authorized user on T-Mobile.com
Adding an authorized user through the website gives you full control over T-Mobile account management without needing to call. Follow these exact steps:
- Log in to your T-Mobile account at T-Mobile.com.
- Select "Account" from the navigation menu.
- Choose "Profile Settings."
- Select "User Roles."
- Click "Add Authorized User."
- Select the phone number or email for the new user.
- Enter their legal first and last name exactly as it appears on their photo ID.
- Confirm the role and submit.
The new authorized user will receive a text message or email to complete the setup process by logging into T-Mobile.com or the T-Life app. If they do not already have a T-Mobile ID, one will be automatically created for them. Until they complete this setup, they will show as "incomplete" in the T-Mobile ID user roles.
How to add an authorized user in the T-Life app
The T-Life app offers the same capability with a slightly different navigation path. Here is the exact tap-path:
- Log in to the T-Life app.
- Select the "Account" tab (previously called "Manage").
- Tap the Gear icon.
- Select "Permissions & Control."
- Choose "User Roles."
- Tap "Add new Authorized User."
- Enter their legal first and last name matching their photo ID.
- Select "Continue to save."
As with the website, the new user will receive a notification to complete their setup, and a T-Mobile ID will be created automatically if needed. The "incomplete" status will appear until they finish the process.
How to add an authorized user over the phone
If you prefer to add an authorized user by phone, call T-Mobile customer service. As the BRP, you must verify your identity by providing your account number or mobile number and the security customer PIN/passcode. T-Mobile may also require the authorized user's Social Security number for verification. Have the new authorized user's legal first and last name, date of birth, and the phone number or email they will use ready. The representative will complete the addition and the new user will receive a text or email to set up their access.
What can an authorized user do on a T-Mobile account?
An authorized user has substantial but limited control. They can make changes to the account that could cause charges, change the rate plan, add or remove services and features, receive notices, and purchase devices (including on an Equipment Installment Plan after the initial seven days of account activation). For account access outside of My T-Mobile and the T-Life app, authorized users must provide the account or mobile number and the security customer PIN/passcode. When visiting a T-Mobile store, they must provide a photo ID.
However, only the BRP on consumer accounts can perform these restricted actions: account type conversion, changing the bill cycle, updating the billing name, canceling or resuming lines, and managing the PIN/passcode. Authorized users cannot perform these tasks.
Frequently Asked Questions
What is the age requirement for an authorized user on T-Mobile?
An authorized user must be at least 18 years old. In Puerto Rico, the minimum age is 21.
Why does my new authorized user show as "incomplete"?
They need to follow the instructions in the text or email they received to finish the process.
What ID does an authorized user need to visit a T-Mobile store?
When visiting a T-Mobile store, authorized users must provide a photo ID that matches the legal name entered during the setup process.
Can an authorized user cancel lines on my T-Mobile account?
No. Only the Billing Responsible Party on consumer accounts can cancel or resume lines. This restriction also applies to changing the billing name, converting account types, and managing the PIN/passcode.
How many authorized users can I add to my T-Mobile account?
T-Mobile does not publicly specify a hard limit on the number of authorized users, so it is best to check with customer service for the most current information. However, only one Primary Account Holder (PAH) can exist per account, and all authorized user additions must follow the verified process.
