The Registration Data Access Protocol is the standards-based service used to retrieve current domain registration data from registries and registrars.

Registration dates · renewal controls

Domain expiry and ownership checklist.

Check the registration dates and registrar reported through RDAP, then make sure the right people can renew, recover and manage the domain your business depends on.

Check a domain

Authoritative service discovery

Look up the registered domain.

Use the name you renew with the registrar, such as example.co.uk, rather than www or another subdomain.

Registration lookup. Results come from the RDAP service listed for the domain. Availability and detail vary between registries.

The part RDAP cannot tell you

Can your business still control and renew the domain?

A registration date is useful, but continuity depends on account access, recovery routes, payment details and clear responsibility.

Registrar loginAt least two authorised people know which registrar holds the domain and can reach the sign-in page. Business-controlled accountThe registrar account and its primary email are controlled by the business, not a former employee or outside supplier. Multi-factor authenticationMFA is enabled and its recovery method does not depend on one person's device. Recovery route testedRecovery email, phone and backup codes are current, protected and available to the right people. Renewal paymentAuto-renew is understood and the payment method will remain valid before the renewal date. Independent remindersCalendar reminders reach more than one responsible person well before the renewal window. DNS responsibilityThe team knows who hosts DNS, who may approve changes and how access is recovered. Supplier exit planContracts and records explain how the domain, DNS and credentials return to the business if a supplier changes.

How the lookup works

RDAP evidence, without an ownership verdict.

RDAP standardises registration-data queries, but different registries publish different fields. The response cannot prove who controls the registrar login today.

01
Find the responsible service
IANA's bootstrap directory is matched label by label to find the RDAP base URL for the domain ending.
02
Make one bounded query
The lookup uses HTTPS, follows at most three validated redirects and accepts a limited JSON response from public network addresses.
03
Show operational fields
Dates, registrar, status, nameservers and DNSSEC delegation are summarised. Personal registrant contact fields are left out.
04
Confirm control directly
Use the checklist and sign in to the registrar to verify renewal, billing, recovery and account ownership.

Domain registration questions

Dates are evidence—not the whole control story.

What is RDAP?

The Registration Data Access Protocol is the standards-based service used to retrieve current registration data from registries and registrars.

Does a past expiry date mean a domain is available?

No. Registration lifecycles can include renewal, grace, redemption and deletion stages. Confirm the live position with the registrar or registry before taking any action.

Why are registrant contact details not shown?

Registration services decide which data is public and often restrict personal information. This tool focuses on operational details and does not display personal registrant contact fields.

Should I enter a website subdomain?

Use the registered domain you renew with the registrar, such as example.co.uk, rather than www, shop or another service subdomain.
