If I bought a name through one registrar, am I allowed to switch to a different registrar?
Yes. The Inter-Registrar Transfer Policy, applicable to all ICANN-accredited registrars, provides that registered name holders must be able to transfer their domain name registrations between registrars. You must wait 60 days after the initial registration or any previous transfers to initiate a transfer.
Transferring Your Domain Name
As a domain name registrant it is one of your rights to transfer your domain name to another registrar or registrant, and to have access to the necessary information from your registrar regarding the process for making a transfer should you wish to do so.
To protect against unauthorized transfers, you must be the registrant of record or the administrative contact for the domain name in order to initiate the transfer process. Always be sure to keep your contact information up-to-date to ensure that you are able to do so.
