You can prevent any company from changing your service provider to another provider with 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.
For further assistance adding or removing a service freeze, contact us at 800-201-4099.
You can add or remove a service freeze on your CenturyLink® local or long-distance service by email, fax, or postal mail. Download the Letter of Authorization to Freeze Preferred Service Provider(s) and send:
