AT&T requires a Number Transfer PIN before any number can move to another provider. From an AT&T mobile line you can request one by calling *PORT, which on a standard keypad is *7678 — the iPhone dialler has no letters, so you enter the digits. You will need your account passcode to complete the request, and the PIN arrives by text. The PIN is the same for every number on the account you are transferring and it expires after 4 days for consumer accounts, 14 days for business. Requesting a new one invalidates all previous PINs, so do not request another after you have already handed one to your new carrier. Two things will stop this working. If Wireless Account Lock is on, no transfer PIN can be used at all — turn it off first. And AT&T Prepaid does not use Number Transfer PINs, so this route does not apply there. **Important:** Never give a Number Transfer PIN to anyone who contacts you. It exists to let a new carrier claim your number, which is exactly what a port-out thief needs. ## How do I use *7678? - Turn off Wireless Account Lock first if you have it enabled. - Dial *7678 from the AT&T line you want to transfer. - Follow the prompts and enter your account passcode. - Read the PIN from the text message AT&T sends you. - Give it to your new carrier within 4 days. ## Which carriers does this apply to? | Published for | AT&T | | Type | Carrier specific | | Good to know | AT&T consumer wireless lines only. Business Wireless accounts cannot use the dialled method, and AT&T Prepaid does not need a transfer PIN. | _Screenshot: The Secret Codes detail screen shows the steps, the carriers and an Open in Phone button._ ## Related security and scam reporting - [UScellular Account Lock](/blog/uscellular-account-lock-iphone/) - [Number Transfer PINs Explained](/blog/number-transfer-pins-explained-iphone/) - [AT&T Wireless Account Lock](/blog/att-wireless-account-lock-iphone/) - [Verizon Account PIN](/blog/verizon-account-pin-iphone/) - [T-Mobile SIM Protection](/blog/t-mobile-sim-protection-iphone/) - [T-Mobile Account PIN Or Passcode](/blog/t-mobile-account-pin-or-passcode-iphone/) See all [security and scam reporting](/blog/iphone-codes/security-and-scams/) or [every category of iPhone codes](/blog/iphone-codes/). ## How Secret Codes helps Secret Codes keeps this and every other entry a search away.
