What is an LOA?

LOA stands for Letter of Authorization or a Letter of Agency. An LOA is a legal document allowing a new service provider or a carrier port a phone number. They represent the signer for moving phone or fax numbers.

LOAs contain all relevant information about phone numbers with the same owner. They provide everything a porting representative needs to transfer a phone number successfully.
