AT&T may call this a Number Transfer PIN, Transfer PIN, or Port Out PIN. Most business customers call it a port out PIN. It is the security PIN used when moving a wireless number from AT&T to another carrier.

This page explains how AT&T business customers can request a port out PIN through AT&T Premier, myAT&T, the myAT&T app, or Business Wireless Support.

Do not cancel AT&T service before the number transfer is fully completed. Keep the line active until the new carrier confirms the number has moved. If the line is canceled too early, the port can fail.
