How to find your billing telephone number (BTN)

CenturyLink keeps asking me for my billing phone number, but I don't have phone service with them. So how could I have a billing phone number?  We get it. It doesn't seem to make sense, but every CenturyLink customer has a billing phone number, which functions as the account number. So where can you find this BTN?

What is a BTN?

If you contact CenturyLink wanting to talk about your account, we need to verify who you are. One of the ways we do that is through a distinct account number. If you only have Internet service with us, we still refer to that number as a "telephone number," even though it's not a phone number in the usual sense. 

We use your "billing telephone number" (BTN) to: 

  • Look up your account information
  • Troubleshoot your DSL line 
  • Make any changes to your service

Also, if you're filling out a CenturyLink form or using our automated phone system, you'll need to have your BTN handy.

Did you know? You might notice that our customer service agents use "billing telephone number" and "account number" interchangeably to mean the same thing.

Where you can find your billing number

You can find your BTN on the top of the first page of your paper bill. Or, if you're logged in to My CenturyLink, look for it at the top right part of the screen. If you haven't received your first bill yet, you can find your BTN in the Welcome Letter we sent. In all cases, you're looking for the words, "Account Number," which is the same thing as the Billing Telephone Number.

If you can't find your BTN or need other assistance, chat with us. We're here to help
