You have a landline, and you want to move your number onto your cell phone with AT&T. That makes sense; maybe you're looking for a way to get rid of your landline service, but keep your number.

In this article, we'll show you the easiest way to transfer or move your landline number to an AT&T cell phone. After following these steps, your existing landline service will be canceled, and folks who call your landline number will be able to reach you on an AT&T cell phone (including the one you already have.)

  1. Collect Your Landline Account Information

  2. Port Your Number to AT&T

  3. Choose a Cell Phone Plan

Step 1: Collect Your Landline Account Information

No matter where you move your landline number, you will need to collect your account information from your current landline provider. Your account information is what allows carriers to access your number and move it onto their system.

Here is what you need to get:

  1. Account Number

  2. PIN Number

  3. Account Holders Full Name

To get your account and PIN, we recommend you call your current landline provider's customer support. Even if your landline is bundled with other services, your current provider will be able to provide you this information. Just give them a call!

Step 2: Port Your Landline Number to AT&T

AT&T has a dedicated process for porting numbers. ("porting" means moving a number from one carrier to another). Once you have your account information, give AT&T's number porting department a call at 1-844-433-0113.

You can also try porting your number by signing up for one of their online plans at at& You will be asked to fill out a form with your account information.

Step 3: Choose a Plan.

AT&T has a variety of plans to accommodate your needs. Maybe you need your landline number to be placed on a simple flip phone with Talk & Text. AT&T offers simple flip phone plans starting at just $20/month. In most cases, they will be able to ship you a flip phone with your landline number already on it.

Before porting your number to AT&T, we recommend selecting a cell phone plan on their website that closely matches your needs. Remember, you don't need the latest and greatest option. Often just a simple flip phone will do the trick!

And that's all you need to do. Once you get on the phone with AT&T and provide them your account information, they will be able to take care of you from there.
