Important: Ensure all details (e.g., customer number and name) match those on file with your current provider to avoid delays.

Duration of Porting

• A single-line port takes at least 7 business days.

• Multi-line ports require at least 10 business days. sipgate will notify you of the confirmed porting date once your current provider accepts the application.

Canceling a porting request

• Ports can be canceled if the completion date is at least seven calendar days away.
