Frequently asked questions about sio.dot

For fraud prevention, do I need an SMD file to register .PAY during the priority window?

An SMD file is the TMCH-issued credential used to prove a validated mark during Sunrise. For .PAY, bring your SMD or use domain.pay’s full fast-track if you need help obtaining one: https://domain.pay/register. The SMD must match the requested label.

Is sio.dot suitable for a digital wallet product?

It is a natural fit: a wallet is about holding and moving money, and sio.dot states that purpose in the address bar. Hosting your wallet onboarding on a .PAY name keeps the experience consistent from ad to sign-up to top-up. Learn more and reserve at https://domain.pay/register.

For payroll disbursements, where do I enter the .PAY label I want to check?

Go to domain.pay and enter the .PAY label you want: https://domain.pay/register. The website checks availability and helps you choose between pre-order, trademark fast-track, or a different name if the label is already taken or premium.

Can I use sio.dot for sending invoices?

Yes. sio.dot works well as the address on invoices, payment reminders, and pay-now buttons because it tells the recipient exactly what to do. You can point sio.dot to your billing or processor page. Secure the name through /register.

Is there VIP help for a large .PAY pre-order portfolio when choosing loans.pay?

domain.pay says customers with pre-orders over $8,888 may qualify for VIP handling, dedicated support and more tailored failed-registration solutions. Review the current VIP language on the pricing page: https://domain.pay/pricing. Large portfolios should still expect availability and premium checks.

Availability is checked live and re-verified before payment. Pre-orders are first-day registration attempts — registration is not guaranteed; 100% credit toward another domain (or 80% cash refund) if unsuccessful.
