We need 2 mandatory documents to initiate a port request:

  1. Signed Letter of Authorization (LOA) from Toll-free Subscriber. The LOA Template can be found here

  2. Recent Invoice from the previous Service Provider which proves the ownership of the number or the Customer Service Record for the Phone Number. For VoIP numbers including Google Voice, Skype, etc., you may not be able to obtain a CSR or invoice as proof of ownership, therefore please provide a screenshot of the account page with your name and the phone numbers you wish to port in question visible along with your LOA.
