How to Register Your Pet in Korea (동물등록제)

Dog registration in Korea is mandatory. Every dog aged 2 months or older must be registered in the animal registration system (동물등록제). The rule has applied nationwide since January 1, 2014 under the Animal Protection Act (동물보호법). Cats are a separate case and are covered at the end of this guide.

The deadline: when registration is required

A dog must be registered by the time it reaches 2 months of age (60 days). If you adopt an older dog that is not yet registered, register it as soon as possible.

This applies to foreign residents and Korean nationals equally. The registration system does not distinguish by nationality. What you need is a dog, an Alien Registration Card (외국인등록증), and a Korean residential address. If you do not yet have an ARC, see the ARC registration guide first.

Two registration methods

You choose one of two methods when you register.

Internal microchip (내장형 마이크로칩)

A vet implants a small RFID chip under the skin at the back of the neck. The procedure takes a few minutes and is similar to a standard injection. The chip contains a unique identification number that links to your registration record.

• Government registration fee: 10,000 KRW (as of 2026, verify at animal.go.kr)
• Total cost at a vet clinic, including the implant: typically 30,000-50,000 KRW
• The chip is permanent. It cannot be lost, removed by accident, or left at home.
• At some Seoul dog parks (반려견 놀이터), the chip also serves as an RFID entry token.

This is the method most vets recommend. It is also the only option available for cats.

External wearable tag (외장형)

A registered tag is attached to the dog's collar. The tag contains a chip that holds the registration number.

• Government registration fee: 3,000 KRW (as of 2026, verify at animal.go.kr)
• Total cost including the device: approximately 8,000 KRW
• The dog must wear the tag every time it leaves the home. If the tag is lost or broken, you need to get a replacement and update the registration.

The external tag costs less upfront but requires ongoing attention to make sure the dog is wearing it.

Where to register

You have four options:

1. Designated vet clinic. Most vet clinics that handle dogs are authorized to process registration. Call ahead to confirm. Bring your ARC and the dog.
2. Authorized pet shop. Some pet shops are authorized registration points. Less common than clinics but available.
3. District office (시군구청). Walk in to your local city or district office. Staff process the paperwork in person. Bring your ARC and the dog.
4. Online at animal.go.kr. If your dog already has a chip from a previous registration or from entering Korea, you may be able to complete the process online. The site is primarily in Korean.

For most foreign residents, registering at a vet clinic in person is the most straightforward option. You can handle registration at the same appointment as your dog's first health check in Korea.

Registering with an ARC

Foreign residents register using their Alien Registration Card (외국인등록증) and their Korean residential address. The registration system links to your ARC number. There is no additional paperwork for foreign residents beyond what Korean nationals provide.

If your ARC shows a different address from where you currently live, update your ARC address first. Your registration address must match your actual residence. See the ARC registration guide for how to update address information.

Fines for non-compliance

Non-registration carries escalating fines per the Seoul Metropolitan Government's 2024 enforcement notice (as of 2026, verify at animal.go.kr):

Failure to report a change in your pet's status carries a separate, lower set of fines:

Seoul enforces registration through street inspections and follows amnesty periods with active checks. Being caught during an enforcement period without registration results in a fine on the spot.

---

Amnesty periods: register now, no fine

Seoul runs voluntary self-reporting windows where fines are waived for owners who come forward and register. According to the Seoul city news portal, an amnesty period runs from May 1 to June 30, 2026. Enforcement inspections typically follow.

If your dog is not yet registered, the amnesty window is the time to do it. The registration fee is the same whether you register during amnesty or not. The only difference is that the fine for late registration is waived.

---

What you must report: 10-day and 30-day rules

Registration is not a one-time task. Two reporting deadlines apply, depending on what changed.

Within 10 days:

• Your pet goes missing

Within 30 days:

• Your pet dies
• Ownership transfers to another person
• You change your residential address, phone number, or other owner contact details
• You or your pet relocates overseas
• Your pet is found after being lost
• Your pet's external tag is reissued

The shorter window for a missing pet exists because recovery becomes harder the longer the database is out of date. If you are unsure which window applies, report immediately: there is no penalty for being early.

Report changes through the registration portal at animal.go.kr or at your local district office (시군구청). The change-of-information fines apply regardless of whether the original registration was completed on time.

If your pet dies and is registered, reporting the death also closes the loop with the legal disposal requirement. See the end-of-life guide for that step.

Cats: voluntary, with one difference

Cat registration is voluntary nationwide. Seoul and Gyeonggi Province run expanded pilot programs, but no fine applies to unregistered cats anywhere in Korea as of May 2026. Verify the status at publish time, as the legislative direction is toward broader coverage.

Even without a legal requirement, registering a cat is practical. A microchipped cat that gets lost and arrives at a shelter can be matched to its owner through the database.

One key difference from dogs: cats can only be registered using an internal microchip (내장형 마이크로칩). There is no external tag option for cats.

Quick reference checklist

Use this before your appointment:

• Dog is at least 2 months old
• You have your Alien Registration Card (외국인등록증) with you
• Your ARC address matches your current residence
• You have decided between internal microchip and external wearable tag
• You know which vet clinic, authorized pet shop, or district office you will use
• If registering online: your dog already has a valid chip number in the system

After registration:

• Keep your registration certificate or confirmation number
• If you chose an external tag: confirm the dog wears it every time it leaves home
• Set a reminder: if your pet goes missing, you have 10 days to report it; for other changes (death, ownership transfer, address change, relocation overseas), you have 30 days

FAQ

Does a foreign resident have to register their dog in Korea?

Yes. The animal registration system (동물등록제) is mandatory for all dogs aged 2 months or older in Korea, regardless of the owner's nationality. You register using your Alien Registration Card (ARC) and a Korean residential address. The process is identical to that for Korean nationals.

What is the difference between an internal microchip and an external tag?

An internal microchip (내장형 마이크로칩) is implanted under the skin by a vet, costs approximately 30,000-50,000 KRW all-in, and cannot be lost or removed. An external wearable tag (외장형) attaches to the collar, costs approximately 8,000 KRW all-in, and must be worn by the dog whenever it leaves the home. Veterinarians generally recommend the internal chip because it is permanent and doubles as the dog's identifier at some Seoul dog parks.

Where can I register my dog in Korea?

You can register at any designated vet clinic, an authorized pet shop, or your local district office (시군구청). You can also complete registration online at animal.go.kr. Bring your ARC and your dog. Staff at the clinic or district office will process the paperwork.

What is the fine if I do not register my dog?

Fines are escalating. A first offense costs 200,000 KRW, a second offense costs 400,000 KRW, and a third offense costs 600,000 KRW. Seoul runs periodic amnesty windows where these fines are waived for owners who voluntarily self-register. An amnesty period is running from May 1 to June 30, 2026.

What changes must I report, and within how long?

You must report any of the following within 30 days: your pet's death, a change of ownership, a change of address, departure overseas, the pet going missing or being found, or a microchip being reissued. You report through animal.go.kr or at your district office. Failure to report carries a fine of 100,000 KRW for a first offense, 200,000 KRW for a second, and 400,000 KRW for a third.

Do I need to register my cat?

Not by law. Cat registration is voluntary nationwide. Seoul and Gyeonggi Province have expanded pilot programs, but no fine applies to unregistered cats anywhere in Korea as of May 2026. Still, registering your cat makes it easier to recover if it gets lost. Cats can only be registered using an internal microchip, not an external tag.

Is there an amnesty period if I am behind on registration?

Seoul runs voluntary self-reporting windows periodically where fines are waived for owners who come forward. The most recent window runs from May 1 to June 30, 2026, according to the Seoul city news portal. After amnesty periods, Seoul typically runs enforcement inspections. If you are behind, registering during the amnesty window is the most cost-effective option.

What if my dog was already microchipped before I moved to Korea?

If your dog already has an ISO 11784/11785-compliant 15-digit microchip, the existing chip number can usually be used for Korean registration. Bring your dog and its health records to a designated vet clinic or district office. Staff will scan the chip and link it to your registration record. If the chip does not meet the ISO standard, a new chip will need to be implanted.
