Transferring domains between owners is a simple process involving the domain registrars of both the buyer and the seller.
A domain registrar is a company like GoDaddy, Name.com, etc. which holds all the information pertaining to the domain's ownership.
If buyer and seller have accounts on the same domain registrar, the process is straightforward. The seller simply retrieve's the buyer's account ID and requests a "domain push" within their control panel.
If buyer and seller have accounts on different domain registrars:
- The buyer may initiate the transfer by contacting their domain registrar, who will then reach out to the administrative contact of the site's old registrar.
- The seller may facilitate a smooth transfer by unlocking the domain and providing an authorization code or an EPP code.
Each domain registrar may have different processes. For more detailed information, you may contact your domain registrar for the exact process for transferring domain ownership.
