.tr WHOIS Lookup: Second-Level Zones and Fields
.tr entered the root zone on 17 September 1990. Its registry is the Information and Communication Technologies Authority (BTK), and TRABIS operates the zone on the authority's behalf. A single WHOIS server, whois.trabis.gov.tr, answers for the whole family. Names registered directly under .tr and names in com.tr, org.tr, net.tr, gov.tr or edu.tr all come from the same place. The zone is signed with DNSSEC.
A TRABIS reply is split into blocks that start with two asterisks, one each for the registrant, the registrar, the domain servers and additional info. The registrant block opens with the holder's personal name or company title. The address, phone, fax and email lines that follow read Hidden upon user request when the holder has asked for privacy. The registrar block is public in full, NIC Handle included. No abuse contact or DNSSEC line is published. For commercial names, open the .com.tr WHOIS lookup.

WHOIS FAQ
Does a .tr WHOIS lookup also cover com.tr and org.tr names?
Yes, whois.trabis.gov.tr answers for every .tr sub-zone, so you look up a com.tr, org.tr or edu.tr name exactly as you would a name registered directly under .tr. The block layout stays the same in every sub-zone and only the content changes. Government addresses under gov.tr are open to queries as well and show the holder's title and registrar like any other record.
Can I see who owns a .tr domain in a WHOIS lookup?
Yes, the first line of the registrant block gives the holder's name or company title, and a privacy request does not hide it. Privacy covers the four contact lines that follow. A .tr record therefore tells you who holds the name but usually not how to reach them. For contact, go through the registrar, whose address and phone number stay visible in the record.
What is the IP address next to a name server in a .tr record?
The IP address next to the host name is a glue record. When a domain uses a name server inside its own zone, such as ns1.example.tr, resolvers need that server's address from the parent zone before they can reach it. TRABIS prints the same address in the WHOIS reply. Name servers in another zone need no glue, so their lines show only the host name.
Where is the expiry date in a .tr WHOIS record?
The expiry date sits on the Expires on line of the additional info block, and the registration date on the Created on line. TRABIS writes both as year, abbreviated English month and day, closing the line with a dot, and stamps the last update time with Türkiye's +03:00 offset. Tools that expect ISO dates misread this layout. The whois.com.tr result screen converts the dates to a standard format.
Is there an RDAP service for .tr domain names?
No, IANA's RDAP bootstrap registry has no endpoint for .tr, so port 43 WHOIS is the only machine-readable source of .tr registration data. The ICANN rule that made RDAP the definitive source on 28 January 2025 binds generic extensions only. For a country code extension the national authority makes that call, and for .tr that authority is BTK.
How does an unregistered .tr name show up in a WHOIS lookup?
An unregistered .tr name gets a short No match found reply from the server, with none of the usual blocks. The result screen lists such a name as available. Names reserved under TRABIS policy can return the same empty reply, so an empty reply alone does not prove that a name can be registered.
