And, sometimes account activities will change your account number, and this new account number needs to be added to your My CenturyLink before you can use it to pay or view your bill.

It's fast and easy to do both, if you have the right items handy before you start. The first is your account number, which you can find on your paper bill. The second varies: you'll either need the zip code of your billing address or a security code.

Want to register now? If not, you can click the "Enroll Now" button on the My CenturyLink sign in page whenever you're ready.

If you've moved, or changed important information on your account, then we may create a new account number to replace the old one. You can see and manage both accounts in My CenturyLink.

To add a new account to your My CenturyLink profile, go ahead and sign in to My CenturyLink with your current username and password. Then select "Add Account" from the account drop down menu on the top right of the screen.

Your online account contains enough personal information that CenturyLink and the Federal Communications Commission (FCC) agree it should be secured from unauthorized access. Sometimes it might feel like it's too secure, but please understand that we aren't intentionally trying to be difficult. Rather, we take every customers' privacy very seriously.

While some accounts have a security code, others may have a security question and answer. Until you've created a security question and answer, your account is given a random system generated security code.

You have the option to request your security code. It's also available in the registration or add new account form. You'll be able to choose either an automated voice message, which will call the primary telephone number on the account right away with the information, have it emailed to the email address on the account, or have a paper letter sent to the billing address.
