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 .com.tr?

.com.tr is the commercial second-level zone under .tr and the extension most companies in Türkiye use. It is a zone inside .tr, not a TLD of its own, and it is on the Public Suffix List, so example.com.tr is treated as a registrable domain.

Who can register it

Until 2022 a .com.tr application had to be supported by documents such as a trade registry record or a trade mark certificate showing a right to the name. Since TRABİS went live in September 2022, .com.tr is allocated without documents, first come, first served, through accredited registrars (KK). Conflicts over a name are now resolved after the fact, through the dispute resolution procedure.

WHOIS, RDAP and privacy

.tr 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.trabis.gov.tr). 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 .com.tr domain?

Until 2022 a .com.tr application had to be supported by documents such as a trade registry record or a trade mark certificate showing a right to the name. Since TRABİS went live in September 2022, .com.tr is allocated without documents, first come, first served, through accredited registrars (KK). Conflicts over a name are now resolved after the fact, through the dispute resolution procedure.

How do I run a WHOIS lookup for a .com.tr domain?

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

Does .com.tr support RDAP?

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

Is .com.tr a top-level domain?

No. The top-level domain is .tr; .com.tr is a second-level zone the registry operates beneath it. Because it is on the Public Suffix List, tools and browsers treat example.com.tr as the registrable domain. WHOIS and RDAP data come from the .tr registry.
