How to freeze your local or long-distance service provider

Prevent any company from changing your service provider to another provider by putting a service freeze on your CenturyLink local or long-distance services — at no charge.

A service freeze protects your service from getting "slammed," i.e. having one of your chosen phone service providers changed without your permission. Sometimes this service is known as a PIC freeze.

A freeze does not prohibit you from making changes to your services and your service providers at any time, but you must contact us directly with a verbal, written or electronically signed authorization. Once a freeze is effective, authorization given to others, even in writing or verified by a third party will not be enough to change the provider of that service.
