Bangkok Pet Registration: 2 Months Left – 2026 Step-by-Step Guide and Free Microchip Points

It may still feel far off, but the end of the year is already approaching. Mandatory registration of dogs and cats in Bangkok starts on January 10, 2027 – about two months from now. Based on the official information available today, this article explains the steps to register and where you can get the service for free.

The start date is January 10, 2027, confirmed in the Royal Gazette

On January 7, 2026, the Bangkok Metropolitan Council approved a one-year delay of the city ordinance on keeping dogs and cats (enacted in 2024). The reasons given included far more pets than expected, only 8–10 permanent service points, and issues around landlord consent letters for rented homes.

The amending ordinance was published in the Royal Gazette (ราชกิจจานุเบกษา, the Thai government's official journal) on January 8, 2026, setting the start date at January 10, 2027. As of November 8, 2026, we have found no official announcement of a further delay.

Registration in three steps

The detailed rules are set out in a Bangkok Metropolitan Administration notification published in the Royal Gazette on January 23, 2026. The process is as follows.

• Get a microchip: a 15-digit chip that meets ISO 11784/11785 and is certified by ICAR (the international animal identification body) is implanted under the skin on the back, around the shoulder blades.
• Receive the certificate: after implantation, a certificate (form คลส.1) is issued.
• Register: at a BMA veterinary clinic, a district office (สำนักงานเขต), or online (petregis.bangkok.go.th). Online registration requires logging in with the ThaID identity app.

Microchips can be implanted at BMA veterinary clinics and at licensed private animal hospitals. If you get the chip at a BMA clinic, you can complete registration on the spot.

Documents to prepare

• Microchip implantation certificate (คลส.1)
• Dog/cat registration application form (คลส.2)
• Owner's ID document
• House registration (ทะเบียนบ้าน) for the address where the pet lives
• Landlord's consent letter if you rent
• Power of attorney if someone applies on your behalf

For foreign residents, official information does not state which ID or address documents are accepted. It is a good idea to call the service point before you go. ThaID is based on Thai identity cards, so if you cannot use it, plan to register in person.

Get ready this month, before the rush

Even the City Council has raised concerns about crowded service points just before the start date. With the year-end holidays in between, it is best to act early.

• If your pet already has a chip from Japan or elsewhere, ask your vet to check the number and standard (ISO 11784/11785)
• If you rent, ask your landlord or property manager for a consent letter
• Keep the certificate (คลส.1) and other documents both on paper and on your smartphone
• Call the service point in advance to ask which documents foreign residents need

Summary

Mandatory dog and cat registration in Bangkok starts on January 10, 2027. Get a microchip, receive the certificate (คลส.1), and register at a BMA clinic, a district office or online. Services are free at BMA facilities, so start preparing before the rush.
