Required Documentation for Porting Telephone Numbers

Reliable documentation verifying active service on your porting telephone numbers can assist in resolving many issues that arise when attempting to port phone numbers from a losing carrier. Flowroute often has to request customer assistance to provide proper documentation during the process if the document is not correct at the onset.

NOTE:  If you are porting multiple telephone numbers, they must all be listed on the documentation under one account; if the telephone numbers are on multiple accounts, then separate port orders must be created for each account. Failure to do this results in needless rejections and delays.

The cornerstone of proof of active service is a legible Copy of Bill (CoB). A CoB is usually an invoice from the current service provider showing: 

  • a dated statement within the past 30 calendar days
  • all porting telephone numbers
  • the provider/carrier logo or name

A bill copy is an essential component of porting and should be uploaded. In cases where the bill copy does not list the porting telephone numbers, additional documentation is recommended to supplement proof of ownership. Types of documentation can include: 

  • A customer service record (CSR) from the current service provider listing the porting telephone numbers and the address on file.
    NOTE: Toll-free numbers do not have CSRs.
  • An email from a representative of the current service provider dated within the past 30 days listing the porting numbers

  • A screenshot of your provider’s account portal showing the porting numbers, this should include enough information to link it to a bill copy. The document needs to include the account number and the provider’s logo. 
NOTE: All uploaded documents must be in a PDF format.
