An EPP (Extensible Provisioning Protocol) code, also known as an authorization code or transfer code, is a unique alphanumeric code used to facilitate domain transfers between domain registrars. It serves as a security measure to ensure that only the domain owner or an authorized party can initiate a domain transfer.

When you want to transfer a domain name from one registrar to another, you typically need to obtain the EPP code from the current registrar. The EPP code acts as a password or authentication token for the domain. It helps prevent unauthorized transfers and ensures that the domain owner has control over the transfer process.

The EPP code is usually generated by the current registrar and can be obtained through your domain management account or by contacting their support. Once you have the EPP code, you can provide it to the new registrar during the domain transfer process. The new registrar will use the code to validate your ownership and initiate the transfer request on your behalf.

It's important to note that not all domain extensions use EPP codes, and some registrars may use alternative methods for domain transfers. If you are unsure about the transfer process or the requirement of an EPP code for your specific domain, it's recommended to check with your current registrar or the new registrar where you intend to transfer your domain.
