TM30 in Thailand: Foreigner Address Reporting Without the Mess

TM30 sounds small until an address confirmation becomes relevant to another immigration matter. Then “the address is somewhere in a chat” reveals itself as less of a system and more of a ritual sacrifice to chaos.

This guide explains TM30 in practical, careful terms. It is not legal advice or an official instruction. Local immigration offices may apply procedures differently, so important decisions should be checked with official sources or the relevant office.

The short answer

TM30 is the notification of a foreigner’s place of stay in Thailand. In practice, it relates to the address where a foreigner is staying: a hotel, apartment, house, rented room or other accommodation.

The notification is usually handled by the owner, hotel, landlord, house master, accommodation manager or another responsible party. The foreigner is often not the main person filing it, but should know whether it was done and keep confirmation where possible.

What TM30 is

The TM30 form concerns notification of residence for foreigners by the person responsible for the accommodation. Samut Prakan Immigration describes the obligation in relation to house owners, heads of household, landlords and hotel managers accommodating foreign nationals.

TM30 is not a visa, not an extension of stay and not a 90-day report. It is an address notification. That sounds harmless, but a confirmed address can appear in other processes, such as TM47 or TM7.

Who is usually involved

Depending on the accommodation, TM30 may involve:

• a hotel,
• a landlord,
• a building manager,
• a rental agent,
• a house owner,
• a person formally responsible for the place of stay.

The foreigner should know who reports the address, when it is reported and whether confirmation can be provided. This is not dramatic bureaucracy. It is basic document hygiene, the boring cousin of survival.

When TM30 may matter

TM30 may matter when you:

• change address in Thailand,
• move from a hotel to a rented apartment,
• rent a condo or house long term,
• prepare a 90-day report,
• prepare an extension of stay,
• need address evidence,
• need the address in immigration records to match your current stay.

Do not assume that because a hotel or landlord “probably did it”, everything is correct. Ask for confirmation or at least confirm what address was reported.

What to keep recorded

For each stay address, keep:

• the full address in English and Thai if available,
• building or hotel name,
• room or unit number,
• stay start date,
• stay end date if known,
• owner, reception or agent contact,
• TM30 confirmation if provided,
• rental agreement or booking confirmation,
• screenshot or PDF from the system if available.

This helps reconstruct address history. During a longer stay, addresses change faster than memory, and memory was never a particularly reliable storage engine.

What to ask your hotel, landlord or agent

Useful questions:

• Has the TM30 notification been filed?
• Which exact address was reported?
• Can I get a confirmation or reference?
• Do the details match my passport?
• What happens when I return after leaving Thailand?
• Who files a new notification if I move?

No need to interrogate anyone under a lamp. Just collect the facts before they become urgent.

Common mistakes

The first mistake is treating TM30 as purely the landlord’s problem. Even when someone else files it, you may later need the confirmation.

The second mistake is storing the address only in chat. After a few months, building names, room numbers and dates tend to drown under food delivery messages.

The third mistake is allowing the real address, contract address and reported address to drift apart. If they differ, an immigration office may ask questions.

The fourth mistake is ignoring a change of address. Moving accommodation may require a new notification by the relevant responsible party.

How Thaiva helps

Thaiva does not file TM30 and does not replace the owner, hotel or immigration office. It can help organize addresses, stay dates, contacts, documents and confirmations.

The practical benefit is simple: when another immigration matter comes up, you can see where you stayed, when, who the contact was and what confirmation you have. That is not a guarantee of acceptance, but it is structured information instead of a last-minute document search.

FAQ

Does the foreigner file TM30 personally?

Usually the responsible party is the owner, hotel, landlord, house master or accommodation manager. The foreigner should still know whether a notification exists and keep confirmation where possible.

Does a hotel handle TM30 automatically?

Often yes, but it is still sensible to ask for confirmation, especially if you may later deal with immigration matters.

Can TM30 matter for TM7 or TM47?

It can matter as address evidence or as part of local office practice. Requirements depend on the case and office.

Does changing address matter?

Yes. When you change accommodation, confirm who reports the new address and what confirmation you can keep.

Is a screenshot enough?

A screenshot is better than nothing, but a clear PDF, readable screenshot or dated confirmation with address details is safer.
