AT&T may call this a Number Transfer PIN, Transfer PIN, Port Out PIN, or Port PIN. It is used when moving an AT&T wireless number to another carrier.
Quick answer
For most AT&T Business Wireless accounts, the fastest way to request a Number Transfer PIN is online through the account's AT&T online access.
- The primary user on the business account should sign in online.
- Go to the profile or account settings area.
- Look for Transfer phone number or Request new PIN.

This page explains the Transfer PIN process. A Transfer PIN is needed when moving an AT&T wireless number to another carrier.
Important: Do not cancel AT&T service before the number transfer is complete. The line should stay active until the new carrier confirms the number has moved.
Business account note: AT&T Business Wireless accounts may have different online options depending on the type of account and the user's online access and permissions.
Get the Transfer PIN online
If the business account has the correct online access, requesting the Number Transfer PIN online is usually the cleanest option.
- Sign in to the AT&T account online.
- Go to the account profile or settings area.
- Look for Transfer phone number.
- Select Request new PIN.
- The Number Transfer PIN should display on the screen.
- Give the PIN to the new carrier when submitting the transfer request.
Request the PIN close to the time you are ready to submit the transfer because Transfer PINs expire.
AT&T Premier Transfer PIN steps
Some AT&T Business accounts can request a Port Out (Transfer) PIN directly through AT&T Premier.
- Sign in to your AT&T Premier account.
- From the Account Management menu, select Port Out (Transfer) PIN.
- Search for the wireless number you want to transfer.
- Select Create a PIN.
- Review the Port Out Transfer PIN and its expiration date.
- Provide the PIN to the new wireless carrier when submitting the port request.
Do not see Port Out (Transfer) PIN in Premier?
Your Premier login may not currently have that capability enabled. Contact Curtis Matthews, and I can work on getting the Port Out Transfer PIN capability added to your Premier access.
What if the Transfer PIN option is missing?
If you cannot find the Transfer PIN or Port Out PIN option, the issue may be connected to account access, user permissions, account type, or account security settings.
- The wrong user may be signed in.
- The login may not have the required online permissions.
- The Premier Port Out Transfer PIN capability may not be enabled for the login.
- Wireless Account Lock or another account security setting may be blocking the transfer.
- An authorized user or online access update may be required.
Premier users: If Port Out (Transfer) PIN is not available under Account Management, contact Curtis Matthews so I can work on getting the capability added to your Premier access.
Important: Do not keep generating new Transfer PINs if a port is already in progress. A newer PIN may replace an older PIN, which could require the port request to be updated.
Transfer PIN, account passcode, and billing transfers are different
A Number Transfer PIN is used when moving a wireless number from AT&T to another carrier. It is not the same thing as the normal account passcode used for account verification.
Transfer of Billing Responsibility is also different. A billing responsibility transfer moves a line from one AT&T account to another AT&T account.
Simple distinction:
- Staying with AT&T and moving the number to another AT&T account: Transfer of Billing Responsibility.
- Moving the number from AT&T to another wireless carrier: Port Out Transfer PIN.
