To start the porting in process for US numbers, you will need to go supply Fiitfu with the following information:


  • The authorized user or owner’s first and last name.  
  • The corresponding service address. This must be an actual physical address. PO Boxes are not valid addresses.
  • A Letter of Authorization (LOA) signed by the authorized user and/or owner of the number(s). Note that the information on your LOA must match the authorized user name and service address provided by your current carrier.
  • Obtain a Customer Service Record (CSR).
  • A scanned (or electronic) copy of the most recent phone bill, within the last 30 days, that includes the account, owner/authorized user name, and address information for all the numbers you’d like to port.
  • Read the most common reason for rejections to avoid them.
