Port-In/Out Basics FAQ's

What is the difference between a port-in and a port-out?

A port-in is when a number is moving to your carrier from somewhere else — you're the gaining carrier. A port-out is when a customer is taking their number away from your carrier to a competitor — you're the losing carrier. Dealers handle far more port-ins, but understanding port-outs matters for customer retention conversations.

What information do I always need to complete a port?

At minimum: the phone number being ported, the account number on the losing carrier's bill, the transfer PIN (also called a port-out PIN or account PIN), and the billing zip code on file. The account holder's exact name as it appears on the losing account matters just as much, even though it isn't always listed as a separate field.

How long does a port usually take?

Wireless-to-wireless ports often complete within a couple of hours during business hours, sometimes less than an hour. Landline-to-wireless and business or multi-line ports can take one to several business days. These are general ranges — verify current timelines with your carrier or master agent since systems vary.

Why do most ports get rejected?

The large majority of rejections come down to a mismatch between the information submitted and what the losing carrier has on file — usually the account name, a stale or expired PIN, or a billing zip that doesn't match. Verifying each field directly against the customer's current bill or account app prevents most rejections.
