AT&T Business Transfer PIN (Number Transfer PIN)

You need a Number Transfer PIN to move your business wireless number from AT&T to another carrier. For business accounts, the primary user must request it. Do not cancel service before the port is complete.

Quick takeaway: For business accounts, the primary user should request the Number Transfer PIN online in myAT&T. If that option is missing, contact AT&T to request it.
Important: Keep your AT&T service active until the number transfer is fully completed. If you cancel too early, the port can fail and you may have to reactivate service before the number can move.

Method 1: Primary user requests it online

  1. Sign in to your AT&T online account.
  2. Go to your account profile.
  3. Select Settings.
  4. Scroll to Transfer phone number and select Request new PIN.
  5. Your Number Transfer PIN will display on the screen.
Request the PIN close to when you are ready to port out. If you request a new PIN later, older PINs become invalid.

Method 2: If the online option is missing

If you are the primary user on the business account and the online option is not available, contact AT&T Business support and request the Number Transfer PIN.

For business accounts, AT&T says the PIN can be requested online by the primary user or by contacting AT&T, and a rep can generate the PIN and email it to you.

Business accounts cannot use the AT&T app or *PORT method to create a Number Transfer PIN.

How to Get Your AT&T Business Transfer PIN from myAT&T

Follow these steps to request your AT&T Business Transfer PIN through your online AT&T account. This PIN is used to securely move your business number to another wireless provider. Keep the PIN private and give it only to your new carrier.

What Premier users should know

Many business customers manage their wireless accounts in Premier. If your Premier view shows a Port Out (Transfer) PIN option, use it. If you do not see that option, the safest path is for the primary user to request the Number Transfer PIN through the online account or by contacting AT&T.

Do not assume every business login looks the same. Menu options can vary by account setup and access level.

Before you port out

  • Make sure the correct person is signed in. For business accounts, the primary user requests the PIN.
  • Do not disconnect service first.
  • If you have Wireless Account Lock turned on, turn it off before trying to transfer the number.
  • Your business Number Transfer PIN expires after 14 days.
  • Give the PIN only to your new carrier, not to random callers or texts.
