A guest arrives late, hands over a passport, and expects check-in to take two minutes. For the property owner or manager, that passport starts a separate clock: the TM30 report. Knowing what passport details are needed lets you collect the right information once, submit with confidence, and avoid chasing guests for missing photos the next morning.
For most Thailand TM30 filings, the passport is the primary source for the guest’s identity, nationality, passport number, and entry information. But not every field on a TM30 report comes from the passport. The property address and the date the guest arrived at your accommodation matter too. Keeping those two sources clear makes the process much faster.
What passport details are needed for a TM30 filing?
A clear passport photo or scan should show the biographical information page and, where applicable, the current Thailand entry stamp or visa information. The exact fields requested can vary slightly by Immigration Bureau system or the guest’s circumstances, but the core information is consistent.
Identity details from the passport bio page
Start with the passport’s main identification page. This is the page with the holder’s photograph and machine-readable lines at the bottom. For a TM30 report, you will generally need the guest’s full name exactly as printed, nationality, passport number, date of birth, and gender.
Accuracy matters more than formatting preference. Do not shorten middle names, replace a name with a nickname, or guess at spelling when a passport uses unfamiliar name order. Enter the details as the document presents them. A single transposed passport-number character can create a mismatch later, especially for returning guests or a longer stay.
The passport’s expiration date may also be requested by the reporting system or useful for your records. Even when it is not the main reporting field, capturing it helps flag a document that could expire during an extended tenancy.
Thailand entry details from stamps or immigration records
A passport bio page identifies the person, but it does not tell you when they entered Thailand. For TM30 reporting, the guest’s date of arrival in Thailand is commonly needed. This is usually found on the Thailand entry stamp or supported by the traveler’s current arrival documentation.
Depending on the filing flow and the guest’s immigration status, you may also need information connected to the visa or permitted-stay stamp, such as the visa type, visa number, or permission-to-stay date. These details are not always relevant in the same way for every visitor. A tourist, long-term resident, student, or work permit holder may have different stamps and supporting documents.
When a stamp is faint, cropped, or unreadable, do not guess. Ask for another image before submitting. A clear photo taken under good light is usually enough, provided every number and date is legible.
Arrival card or digital arrival information
Older TM30 processes often referred to the TM6 arrival card number. Thailand has changed its arrival procedures over time, including the move to digital arrival information for many travelers. Because the documents a guest holds can differ, treat an arrival-card number as a field to verify when your filing system requests it, not as something to invent when it is absent.
The practical rule is simple: use the guest’s current immigration documentation and provide only accurate information. If a required entry-related field is unclear, resolve it before filing rather than using placeholder text.
What information is not on the passport?
A passport scan is necessary, but it is not the whole TM30 submission. The report also needs details about where the foreign guest is staying and when they arrived there.
For the accommodation portion, you will need the property’s registered address and the date the guest checked in or arrived at the residence. This date can be different from the date they entered Thailand. For example, a guest might land in Bangkok on Monday, stay with friends for two nights, and arrive at your Chiang Mai apartment on Wednesday. Your report should reflect their arrival at your property, not their flight landing date.
The person filing also needs the correct host, owner, or accommodation operator account details. That is a setup issue rather than a guest passport issue, but it is where many first-time filers lose time. Make sure the property is registered correctly before a busy check-in day.
A practical passport-photo checklist
The fastest TM30 filing begins with a usable image. Ask guests for a photo or scan that includes the full page, all four corners where possible, and text that is sharp enough to read without zooming into a blur. Avoid screenshots that cut off the passport number or hide the machine-readable zone.
For entry information, get a separate photo of the Thailand entry stamp or relevant visa page if it is not visible in the same image. Check the year carefully. Dates written in different formats are easy to misread, and an incorrect arrival date can cause an avoidable reporting problem.
Before you submit, compare these points against the image:
Full name and name orderNationalityPassport numberDate of birth and gender, if requestedPassport expiration date, if requestedDate of entry into ThailandVisa, permission-to-stay, or arrival-document details when the form requires them
This short check is worthwhile for every guest. It takes seconds and prevents the much slower task of correcting records after submission.
Common mistakes when collecting passport details
The most frequent error is using the wrong date. Staff may enter the property check-in date as the Thailand arrival date, or use the date a visa was issued instead of the date the traveler entered the country. These dates can all be different, so label them clearly in your internal process.
Another common issue is confusing the letter O with zero, or the letter I with one, in a passport number. This is especially likely when staff type details manually from a low-quality image. Zoom in, compare the number with the machine-readable lines, and request a new image if there is any doubt.
Property managers also sometimes collect only the bio page and realize later that they cannot confirm the entry date. Make the second image part of your standard check-in request for foreign guests. That small change reduces follow-up messages and protects your reporting deadline.
Finally, do not reuse old passport data without checking it. A returning guest may have renewed a passport, received a new visa, or re-entered Thailand since their last stay. Each new arrival should be reviewed against their current documents.
How automation reduces TM30 data-entry risk
Manual entry is manageable for one guest, but it becomes a bottleneck when several guests arrive on the same day. It also creates predictable errors: skipped digits, mixed-up dates, and forms left unfinished while staff wait for an unreliable government portal.
A service such as TM30.io can extract relevant details from a passport photo or scan, populate the reporting workflow, and submit through the immigration system. The key benefit is not just speed. It is a more consistent process: clear document collection, automated data extraction, retry handling when the official system is unavailable, and a confirmation record after submission.
Automation still depends on a readable source document. Think of it as removing the repetitive work, not removing the need to check the guest’s information. A quick review of the extracted passport number and entry date is a sensible control, particularly for high-volume properties.
When passport details need extra attention
Some stays require a closer look. Dual nationals may travel on one passport but have records from a previous stay under another. Guests with long-term extensions, non-immigrant visas, or recent passport replacements may have entry and permission-to-stay information across multiple pages. Families can also hand over several passports at once, increasing the chance of assigning an entry stamp to the wrong person.
In these cases, slow down long enough to match each stamp and document to the correct passport holder. If anything is unclear, ask the guest for clarification while they are still available at check-in. It is far easier than trying to reconstruct the record after they have left the property.
A clear passport image, the correct Thailand entry date, and your property’s accurate address are the essentials. Build those checks into check-in, keep the process consistent, and the TM30 requirement becomes a quick operational task rather than a late-night compliance problem.
