Frequently asked questions
How do I buy extn.in?
Select Buy now, pay with a card or another supported method, and the payment is held in escrow. Once the seller starts the transfer, you confirm the domain is in your account and we release the funds.
How does purchase protection work?
Your payment goes into escrow, not to the seller. The seller only gets paid after you confirm the domain has been transferred to you. If the transfer cannot be completed, you get a full refund.
How long does the transfer take?
Most transfers finish within 1 to 3 days. We guide you through each step, and our support team helps if your registrar asks for extra checks.
Which payment methods can I use?
You can pay with Visa, Mastercard, American Express, PayPal, Apple Pay and Google Pay.
Do I get the website or logo with the domain?
No. You buy the domain name extn.in only. The artwork on this page is a preview to show how the name could look.
Can I get a refund after I buy?
No. All sales are final once you have bought a domain. The one exception is a transfer we cannot complete, in which case the payment held in escrow is returned in full. Our refund policy has the details.
Can I renew the domain after I buy it?
Yes. After the transfer, the domain lives at your registrar and you manage renewals there.
