How to Cancel AT&T Service (2026 Guide)

To cancel AT&T, dial 611 or call 1-800-331-0500. If you're keeping your number, don't cancel — request your transfer PIN and port to your new carrier, which closes the AT&T line automatically.

Keeping your number? Port first — canceling can permanently release it.

To cancel AT&T wireless, contact customer support by phone or chat — dial 611 from your AT&T phone or call 1-800-331-0500. But if you plan to keep your number, don't cancel first: request your transfer PIN and activate with your new carrier instead, and your AT&T line closes automatically once the number transfers. Canceling before porting can permanently release your number.

Key takeaways
Dial 611 or call 1-800-331-0500 to cancel; chat works for simple cases.
Keeping your number? Port first — canceling can release it.
No traditional ETF, but device balances come due and promo credits stop.
You can cancel a single line without closing the account.
Two different situations
Switching carriers and keeping your number? Don't cancel manually — start the transfer with your new carrier. Only fully cancel if you no longer need the number at all.

How to cancel

  1. Call 1-800-331-0500 or dial 611 and ask to cancel your wireless service (identity verification required).
  2. Or use live chat in your AT&T account for simple cancellations.
  3. To remove just one line, sign in > manage wireless lines > cancel line (some accounts still need phone confirmation).
  4. Get a confirmation of the cancellation and the effective date.
Check before you cancel
Review your device installment balance, any promotional bill credits, and your billing cycle end date. Remaining device payments come due and promo credits stop when you cancel early.

Fees and what happens after

  • No traditional ETF on most modern AT&T unlimited plans.
  • Remaining device installments must be paid; promo credits end.
  • Service may stop immediately or at cycle end; a final bill follows.
  • Final-bill proration varies — review your plan and cycle before canceling.

Cancel without losing your number

  1. Keep your AT&T line active.
  2. Get your AT&T transfer PIN (att.com > Profile > Sign-in info, or text PORT to 7587).
  3. Activate with your new carrier and request the number transfer.
  4. Let the completed port close your AT&T line automatically.
Canceling to save money?

Compare AT&T-network MVNOs that use the same towers for much less — porting takes about 30 minutes.
