RDAP availability is taken from the IANA RDAP bootstrap file published on 2026-09-16; WHOIS server and delegation year from the IANA root zone database. Registry policies change: check the registry's own policy before relying on an eligibility rule.

What is .eu?

.eu is the top-level domain of the European Union. It is listed as a country-code TLD because "EU" is an exceptionally reserved ISO 3166 code, and it is operated by EURid, a non-profit appointed by the European Commission.

Who can register it

Eligible registrants are EU citizens wherever they live, residents of an EU or EEA member state, and organisations established in the EU or EEA. After Brexit, UK-based registrants who did not meet these criteria lost eligibility.

WHOIS, RDAP and privacy

.eu is not listed in the IANA RDAP bootstrap file dated 2026-09-16, so no public RDAP service is announced for it. OrbitProbe falls back to the classic port-43 WHOIS server (whois.eu). WHOIS output is free text in a registry-specific layout, so only a fixed set of fields is read (registrar, dates, status, nameservers) and some of them may simply not be present. For ccTLDs, what is published is decided by the registry and local law rather than by ICANN, so output differs from one extension to the next. Most registries do not show the personal data of individuals in public output. OrbitProbe only ever shows the organisation name and country.

FAQ

Who can register a .eu domain?

Eligible registrants are EU citizens wherever they live, residents of an EU or EEA member state, and organisations established in the EU or EEA. After Brexit, UK-based registrants who did not meet these criteria lost eligibility.

How do I run a WHOIS lookup for a .eu domain?

Type the name, in the form example.eu, into the form on this page. Because no RDAP service is published for .eu, OrbitProbe queries the WHOIS server whois.eu. The result shows where the data came from and when it was observed.

Does .eu support RDAP?

The IANA RDAP bootstrap file dated 2026-09-16 does not list an RDAP service for .eu. Registration data is queried through the classic WHOIS server whois.eu. Registries can add RDAP later, so this may change over time.

Does .eu support internationalised domain names (IDN)?

Yes, names containing non-ASCII characters can be registered under .eu. Which characters are allowed is defined by the registry's IDN table. In the DNS such names are stored in Punycode form starting with "xn--"; OrbitProbe accepts either form.
