A
authorization code
A code created by a registrar to help authenticate the registrant of a domain name in a generic top-level domain. The authorization code is a security measure to help prevent fraudulent or unauthorized transfers. This code is required for a registrant to transfer a domain name from one registrar to another.
Some registrars generate authorization codes for their registrants, and some allow registrants to generate their codes through a control panel on the registrar’s website. When registrants request an authorization code from the registrar, the registrar is obligated to provide the code within five days.
