You can change your AT&T phone number online, by phone, or in a store — the process takes a few minutes and is free

AT&T lets you change your phone number without switching carriers or losing your service. The change happens when ready once you confirm it, and your old number is released back into the pool for other customers. You do not need to buy a new phone or change your plan.

The fastest route depends on whether you want to keep your current number temporarily (to notify contacts) or switch right away. AT&T does not charge for a number change, though if you change more than once per account within a short window, they may flag it as unusual activity.

Key Takeaways

  • You can change your number through the AT&T mobile app, the website, by calling 611 from your AT&T phone, or by visiting a store in person.
  • The number change takes effect when ready once you confirm it, and your old number becomes unavailable to you.
  • AT&T does not charge a fee for changing your number, but changing multiple times in a short period may trigger account review.
  • After you change your number, update your contacts, two-factor authentication settings, and any services that use your phone number for login or recovery.

Change your number through the AT&T mobile app

Open the AT&T mobile app, tap the menu icon (three horizontal lines), and select "My wireless" or "Manage my mobile." Look for an option labeled "Change phone number" or "Phone number settings." The app will show you available numbers in your area code or let you search for a different area code.

Select the number you want, review the confirmation screen to make sure it is correct, and tap confirm. The change takes effect when ready. You will receive a text message and email confirming your new number. Keep this confirmation in case you need to reference it later.

Change your number on AT&T.com

Log into your AT&T account at att.com using your username and password. Navigate to "My wireless" and find the line you want to change. Look for "Manage" or "Settings" next to that line, then select "Change phone number."

AT&T will show you available numbers. You can filter by area code or search for a specific number if you have one in mind. Once you select a number and confirm, the change is when ready. You will see your new number displayed in your account right away.

Change your number by calling AT&T customer service

Call 611 from your AT&T phone, or call 1-800-331-0500 from any phone. Tell the representative you want to change your phone number. They will ask which line on your account needs the change and what area code you prefer.

The representative will offer you available numbers and read them aloud so you can choose one. Once you confirm your selection, the change happens when ready. Ask the representative to send you a confirmation email with your new number and the date of the change.

Change your number in an AT&T store

Visit any AT&T store with your ID. Tell a representative you want to change your phone number. They can show you available numbers on their system and process the change on the spot. The change takes effect when ready, and you will receive a printed or emailed confirmation.

Changing in person is useful if you want to ask questions about how the change affects your account or if you have trouble with the online or phone methods. Stores are usually busiest on weekends and late afternoons, so calling ahead to check wait times can save you time.

What to do after you change your number

Update your contacts as soon as possible. Text or call people who need your new number, or post it on social media if you prefer. For work contacts, send an email with your new number and the date it changed.

Log into any accounts that use your phone number for two-factor authentication — email, banking, social media, and work systems — and update your phone number there. If you use your phone number to recover a password, update that setting too. Check any subscription services (streaming, apps, utilities) that have your number on file and update them if needed.

If you use your old number for business purposes, consider setting up a voicemail message on your new number explaining that you have changed numbers and directing callers to reach you another way. Some people keep their old number active for a few weeks by forwarding it to their new number, though AT&T does not offer this service directly — you would need to use a third-party call forwarding app.

What happens to your old number

Your old AT&T phone number is released back into the pool of available numbers. AT&T typically waits 30 to 90 days before reassigning it to another customer, though this varies. You cannot reclaim your old number later, so if you think you might want it back, do not change it.

If you owe money on your account, changing your number does not affect your bill or payment obligations. Your account stays the same; only the phone number changes. If you are trying to avoid contact from a creditor or debt collector, changing your number is temporary — they can still reach you through other means and may pursue other contact methods.

Frequently Asked Questions

Can I choose any phone number I want?

No. AT&T shows you available numbers in your selected area code. You cannot request a specific number unless it happens to be available in their system. Numbers with patterns (like 555-5555) or vanity numbers are rarely available through the standard change process.

Will changing my number affect my plan or bill?

No. Your plan, pricing, and billing stay exactly the same. Only the phone number changes. Your next bill will show your new number, but nothing else changes.

How many times can I change my number?

AT&T does not publish a hard limit, but changing your number more than once per account within a few months may trigger a review. If you change frequently, AT&T may contact you to confirm the changes are legitimate and not fraudulent activity.

What if I change my number by mistake?

Contact AT&T when ready by calling 611 or 1-800-331-0500. If you call within a few hours, a representative may be able to reverse the change and restore your old number. The longer you wait, the less likely they can recover it. After a certain window (usually 24 hours), the change cannot be undone.

Do I need to change my number if I switch from one AT&T plan to another?

No. Changing plans does not change your number. Your number stays with you as long as you stay with AT&T. If you switch to a different carrier, you can port your number to them, or you can let it go and get a new one.
