Find your CenturyLink account number

We try to give you many options to access your account information. Sometimes we ask for your account number. You can find your account number on your bill, in My CenturyLink, and in the Welcome Letter or order confirmation you received when you ordered service.

Get it delivered to your email

We can email your CenturyLink account number to you. For your security, we can only send it to the email address on your account. If you don't have access to that mailbox, you can find your account number in other places, described below.

Find it on your bill

You can find your account number on the top of each page of your monthly bill. Learn how to view your bill in My CenturyLink.

Find it in My CenturyLink

You can find your account number in My CenturyLink on the web or in the app.

On the website, you'll find it in the upper right-hand corner of every page. The image here shows what to look for.

In the app, you'll find it in the upper left-hand corner under the drop-down with your name.

Find it in your welcome letter or order confirmation

In addition to your bill, there are two other documents that show your account number:

  1. Welcome letter. If you haven't gotten your first bill yet, you can find your account number in the Welcome letter we sent when you signed up for service. Look for "Account Number" or "Reference Number" in this letter.

  2. Order confirmation. Any time you start or make changes to your service, you will receive an order confirmation. This includes details about what you ordered and show your account number. If you don't remember getting anything from us in the mail, check your email, as we usually email the confirmation document to you as well.

Other information about account numbers

In some communications we refer to a "billing telephone number (BTN)." If you have CenturyLink internet service only, this may seem confusing, as the BTN is not a typical phone number that you can call. It is simply the number that is associated with your internet line. If you have home phone service, the BTN will be the same as your working phone number.


In essence, BTN and the term "billing account number" (BAN) are all interchangeable and serve as the account number linked to your CenturyLink service.

You may need to use your account number to: 

  • Use the online service troubleshooter to test your internet service
  • Request changes to your service by phone
  • Give to the agent if you call in with any service or repair requests
  • Make a payment online or through the automated phone system

If you still can't find your account number, or have other questions, contact us. We're here to help!
