To change your phone number on AT&T for a wireless line, you can do it yourself online or in the AT&T app, or get help at a store or by contacting support. This process is specifically for AT&T wireless numbers and is separate from updating the phone number tied to your AT&T ID.
How to change your phone number on AT&T
AT&T lets you change a wireless number online, in the AT&T app, at an AT&T store, or by contacting support. The steps are the same whether you use the website, an iPhone, or an Android device. Before you start, know that changing your phone number is not the same as porting a number to another carrier, that requires a separate Number Transfer PIN. You can also change your number by porting a number from another carrier to AT&T, which is a distinct method from the standard number change.
Change your number on the AT&T website
- Go to your wireless account and sign in if asked.
- Select Switch to choose a number, if needed.
- Choose Device options, then Change phone number.
- Complete the form and select Search for available numbers.
- Select the number you want and follow the prompts to complete the request.
Change your number on iPhone or Android
AT&T documents the same steps for iPhone and Android devices. The process is accessed from the account’s Services area.
On iPhone
- Open the AT&T device support page for the iPhone model.
- From the Services tab, select the device you’d like to view.
- Tap Manage.
- Scroll to and tap Change phone number.
- Tap ZIP code.
- Enter your ZIP code and tap Search for available numbers.
- Choose a number and tap Select.
- Tap Change my number.
On Android
- Open the AT&T device support page for the Samsung model.
- Tap Manage.
- Tap ZIP code.
- Choose a number and tap Select.
- Tap Change my number.
Get help from AT&T customer support or a store
You can request the number change by contacting AT&T customer support or visiting an AT&T store. AT&T customer support hotline is available 24/7. You can contact AT&T customer support via live chat or email through their website. When contacting support or visiting a store, you need to provide valid identification (e.g., driver's license or passport). If you need a Number Transfer PIN for porting your number to another carrier, call *PORT from your AT&T mobile device, or get the PIN in the app under Settings > Transfer phone number > Request new. This is not the same as changing your AT&T wireless number, it is only for leaving AT&T. If you are looking for how to change my number on T-Mobile, that process is handled separately by T-Mobile.
