What is a domain authorization code (EPP code)?

A domain authorization code, also known as an EPP code (Extensible Provisioning Protocol code), is a unique authentication key assigned to a domain name by its registrar. It serves as a security measure to ensure that only the domain owner or authorized party can initiate domain transfers between registrars.

Here are the key aspects of a domain authorization code (EPP code):

1. **Purpose**: The primary purpose of the EPP code is to verify ownership and authorize domain transfers. When a domain owner wishes to transfer their domain from one registrar to another, they need to provide the EPP code to initiate the transfer process.

2. **Format**: The EPP code is typically a string of alphanumeric characters generated by the current registrar. It is unique to each domain and is not publicly visible in the domain's WHOIS information or DNS records.

3. **Security**: EPP codes enhance security by preventing unauthorized transfers of domain names. They serve as a safeguard against domain hijacking or unauthorized changes to domain ownership.

4. **Transfer Process**: To transfer a domain to a new registrar, the domain owner must obtain the EPP code from the current registrar. The new registrar will request the EPP code during the transfer initiation process to confirm authorization.

5. **Duration**: EPP codes are valid for a limited period, typically ranging from a few days to a few weeks, depending on the registrar's policies. If the transfer process is not completed within this timeframe, a new EPP code may need to be generated.

6. **Accessibility**: Domain owners can usually obtain their domain's EPP code through their registrar's online account management interface or by contacting customer support. Some registrars automate the process of providing EPP codes upon request.

In summary, a domain authorization code (EPP code) is a crucial element for securely transferring domain ownership between registrars. It ensures that only authorized parties can initiate domain transfers, thereby protecting the integrity and ownership rights of domain names.
