WHAT IS A .CO.KR DOMAIN

.co.kr Domain: South Korea's Commercial Domain Zone

.co.kr is the commercial zone under South Korea's country extension .kr, and it is the most familiar shape a Korean web address takes. The zone is administered by the Korea Internet & Security Agency (KISA) and operated by the Korea Network Information Center (KRNIC) within KISA. The rules come from the Domain Name Management Rules made under Article 13 of the Internet Address Resources Act, last amended on 30 October 2024.

Attached Table 1 states the eligibility for the co zone as 'corporations or individuals', so co.kr is not closed to natural persons. Nor do the rules require a business registration certificate specific to this zone. What does apply here is the general condition in Article 4: both the applicant and the registrant must have an address in the Republic of Korea. If you want a shorter address, .kr is the top level of the same scheme.

Allocation follows what Article 9 calls the order of arrival of the application forms. The accuracy of registration data carries a sanction: Article 11 allows a registration to be cancelled 30 days after the data is found to be false, with a 30-day suspension running first. Article 10 requires changes to be reported to KISA through a registrar. Check the name you are targeting with domain search.

The Korean address condition applies to foreign applicants too: Article 4 of the rules applies to co.kr as well: both the applicant and the registrant must have an address in the Republic of Korea. Because the condition is defined by address rather than nationality, a brand from abroad can apply once it has a valid in-country address and contact arrangement. Settle that arrangement before you apply.

.co.kr Domain Lifecycle

What happens day by day after it expires

Day 0 is the domain's expiry date

In short: for .co.kr the post-expiry timeline is set by the registry, so it differs from one extension to the next. The diagram below shows the windows that actually apply to .co.kr, day by day. One thing never changes, whichever extension you hold: renewing before the expiry date is always the cheapest and safest route.

Domain Is Available (Available)

Open-ended

A .co.kr address at this stage has not been taken yet, and it goes to whoever registers first. Check the name you have in mind — if it is free, it can be yours within minutes.

Domain Is Active (Active Period)

1 - 10 years

Once registration is complete, the domain is registered to you for the term you selected. You can renew at any point before it expires to keep it active, or switch on auto-renewal so you never have to watch the date.

Renewal Window (Grace Period)

Day 0 – 30

The registration does not end on the expiry date: for .co.kr the registry keeps the name for you during this window, and a renewal brings it back. Depending on the registry, the site and e-mail may stop working from day 0, so renewing before expiry is still the safe route.

Domain Is Available Again

After day 30

Once deletion completes, the domain leaves the system and anyone can register it — popular names are often taken the same minute by someone watching. Keep auto-renewal on so a name you care about never gets this far.

Frequently Asked Questions About .co.kr Domains

The questions people actually ask before registering — answered plainly.

  • Attached Table 1 states the eligibility for the co zone as corporations or individuals, so the zone is not closed to natural persons. Nor do the rules require a business registration certificate specific to it. What decides the matter is the general condition in Article 4: both the applicant and the registrant must have an address in the Republic of Korea. If you want a shorter address, .kr is the top level of the same scheme.

  • Yes. Article 4 of the rules applies to every .kr zone and admits no exception: both the applicant and the registrant must hold an address in the Republic of Korea. Because the condition is defined by address rather than nationality, a foreign company can register once it has a valid in-country address and contact arrangement. Settling that arrangement is the longest item in the process; the registration itself proceeds normally afterwards.

  • Both sit under the same registry and the same rules, and the Korean address requirement applies to both. The difference is purpose and shape: co.kr is the third-level zone set aside for commercial use and the most familiar address form in Korea, while .kr is the top level and keeps the name short. The character rules differ slightly too: co.kr allows a minimum of 2 characters, directly under .kr the minimum is 3.

  • Article 9 of the rules ties allocation to the order of arrival of the application forms; KISA may use a separate method only where the public interest requires it. If two parties want the same name, what decides it is when the application arrived. If your Korean address arrangement is ready, waiting gains you nothing; check the name with domain search.

  • Third-level names are 2 - 63 characters long and are built from the letters A-Z, the digits 0-9 and the hyphen. A name may not begin with a hyphen or with 'xn--', and may not end with a hyphen. Korean syllables are defined for names taken directly under .kr, where a name containing Hangeul runs from 2 to 17 characters.

  • Article 11 of the rules provides that a registration may be cancelled 30 days after the data is found to be false, with a 30-day suspension running before cancellation. Suspension means the address stops resolving in practice — website and email go down. Article 10 requires changes to be reported to KISA through a registrar. When the Korean address or the responsible person changes, do not delay that filing.

  • Article 25 of the rules lists what a lookup shows: the registrant's name and address, details of the management officer, name server information, the registrar's name and the registration dates. The same article forbids KISA and the registrars from using that data, or passing it to third parties, beyond the scope stated in the terms of use. You can run the lookup on the whois search page.

  • Article 12 of the rules opens a route to the Internet Address Dispute Resolution Committee for anyone in dispute over the registration, holding or use of a domain name. Where the parties accept — or are deemed to have accepted — a draft conciliation, and where a court decision becomes final, KISA or the registrar acts on the result.
