How long does it take to transfer my existing domain name?

This pretty much depends entirely on the Administrative Contacts and specifically, how fast they reply to the e-mail sent from IndicHosts.net, approving the transfer of the domain name in question. You should also ensure your domain name is Not REGISTRAR-LOCKED as this will automatically nullify the transfer request. These two are the only steps in transferring a domain name that can cause a hold up.

If the Administrative Contact sends the authorization back immediately and your domain name status is ACTIVE, your domain name could be transferred within 2 to 4 days but can take up to 7 days to complete.
