Frequently asked questions about siss.dot

As a bank or credit union, 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.

How do I prove I'm eligible for siss.dot?

Proving eligibility for siss.dot usually means providing accurate registrant details and, where requested, information showing your payment or financial-related intended use. The .PAY registry may run validation checks before activation. domain.pay helps you prepare and submit what's needed; begin at https://domain.pay/register.

Is .PAY a good fit for subscription billing when choosing travel.pay?

.PAY can work for subscription billing, account payment, renewal and failed-payment recovery flows. Search brandable options on domain.pay: https://domain.pay/domains. A clear .PAY label can reduce confusion when customers need to update payment details.

What makes siss.dot different from a .com?

Unlike an open TLD, siss.dot sits in the .PAY namespace operated by Amazon Registry Services, which may apply eligibility and validation expectations around payment-related use. This positions siss.dot for financial branding. domain.pay can register it for you at https://domain.pay/register.

Do premium .PAY names cost more than standard names for crypto payments?

Premium .PAY names can carry additional registry retail fees set by Amazon Registry Services. domain.pay says premium retail can vary by tier, so check the exact label before paying: https://domain.pay/pricing. The pre-order or fast-track fee does not make a premium name standard-priced.

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.
