Thailand incorporation checkpoint
Thailand Company Name Reservation: DBD Rules and 30-Day Validity
Reserve a viable name, protect the filing window, and keep the incorporation record consistent from the first DBD submission.
A Thailand company name reservation is a short, preliminary DBD control, not incorporation and not a trademark clearance. Once the Department of Business Development accepts a proposed juristic-person name, the reserved name must be used for the registration filing within 30 days of the reservation date. If the thirtieth day is a business holiday, the next business day is treated as the deadline under DBD’s published reservation rule.
The practical risk is not the reservation fee; it is losing time after a name is accepted while the founders are still resolving shareholding, Thai-language particulars, signing authority, address evidence, or the proposed business objectives. Treat the 30 days as a filing deadline with a documented owner, not as time during which the name is permanently protected.
Key takeaways
- A DBD acceptance reserves the name for the registration process; it does not create the company, grant a business licence, or clear a trademark.
- Use the 30-day period to complete the incorporation filing, not merely to choose directors or draft a business plan.
- The Thai and English versions should correspond in meaning or pronunciation, and restricted or misleading wording can require correction.
- A name that passes an automated reservation check can still cause downstream issues if its wording conflicts with the real activity, sector approval, or separate intellectual-property rights.
- Foreign founders should settle the ownership and activity analysis before relying on a name reservation as their project milestone.
How the 30-day reservation window works
The clock runs from the date on which the name is reserved, not from the date a founder later starts preparing incorporation documents. The DBD’s published name-reservation text states that a reserved juristic-person name must be registered within 30 days; it also addresses a final day that falls on a business holiday. Keep the reservation confirmation with the incorporation file and record both the reservation date and the calculated deadline.
The safest project plan works backward from that deadline. Allow time for the Thai and English name details, Memorandum of Association particulars, capital and share-allocation decisions, director signing authority, registered-office support, required identity documents, and any foreign-investment review. DBD’s current automated juristic-person name reservation portal is the operational source for the live reservation result; do not rely on a screenshot or an email summary if the portal record differs.
Put the 30-day deadline behind a complete filing plan
An early review can identify whether the proposed name, activity wording, ownership route and incorporation documents are ready to move together.
What DBD assesses in a proposed name
The reservation process is designed to prevent a name from entering the register where it is unavailable, prohibited or likely to mislead. DBD’s published rules require the requested Thai and English names to be entered together; the English version must have the same meaning as, or a pronunciation corresponding to, the Thai name. A different foreign-language form requires the supporting request contemplated by the DBD rule.
The same rules identify categories that need particular care: royal or current royal-family names, government or public-authority wording without permission, country names used outside the prescribed format, wording that suggests government or international-organisation ownership, and terms that imply regulated financial or similar activities without the required support. The exact rule wording and current notices should be checked in the DBD legal materials when a proposed name uses a protected, regulated or public-facing term.
For foreign founders, this is where a literal English brand translation often fails. A name can be linguistically attractive but still produce a Thai version that is confusing, carries an unintended regulated meaning, or does not align with how the company will be presented to a bank, customer or licensing authority. HSJGlobal supports Thailand company registration projects by checking whether the name reservation is coordinated with the underlying entity and foreign-founder filing requirements; DBD, a regulator and a bank each remain responsible for their own decision.
Before the name is treated as a project green light, compare the proposed shareholders, directors, business objectives and filing sequence with Thailand company formation requirements . The name reservation is one input to incorporation; it cannot cure a document, ownership or business-activity mismatch.
The relationship between an accepted name and the next filing steps is easier to manage when the team separates the name decision from the evidence needed to establish the company.
A filing-ready reservation workflow
- Choose the legal vehicle and real activity first. A Thai private limited company, partnership, branch or representative office has a different filing path. Name selection should follow the vehicle and the business purpose, not substitute for them.
- Prepare both language forms together. Confirm the Thai spelling, English presentation and the correct entity suffix before submitting. Do not leave translation choices for after acceptance.
- Check regulated words before reservation. If the wording could imply banking, finance, securities, education, a government connection or another controlled activity, identify the competent authority and needed support before filing the name.
- Submit and retain the official result. The reservation result should be available to the authorised person who will complete the incorporation filing; it is not enough to circulate an informal proposed-name list.
- Set a deadline owner. Assign one person to confirm that the company filing is submitted inside the reservation period, and escalate immediately if shareholder, director, address or supporting-document issues are still unresolved.
For a private limited company, the name reservation should be coordinated with the incorporation record rather than handled as a standalone marketing task. The private limited company registration sequence explains why the company’s constitutional particulars, people and documents need to be ready to follow the name result.
Why name acceptance is not full clearance
DBD name reservation and legal-operating readiness are separate questions. An accepted company name does not decide whether a proposed activity is restricted to foreigners, whether an FBL, FBC, BOI route or sector licence is needed, whether a bank accepts the account application, or whether the name conflicts with a registered trademark. Each issue has its own authority, evidence and timing.
The DBD’s digital-registration communications confirm that online incorporation has its own verification, electronic-signature and payment stages. A name reservation therefore should be treated as a dependency in that workflow, not as evidence that the company is already formed. If the filing cannot be completed, the practical recovery is to re-check the current portal result, correct the missing issue, and make a fresh name plan where the reservation has expired rather than assuming a lapsed result can be reused.
When to reserve and when to pause
Reserve a name when the legal vehicle, name language, business objectives, key people and filing timetable are sufficiently settled to complete the incorporation process within the live 30-day window. The better outcome is a short reservation period followed by a clean filing, not a reservation made weeks before the project is ready.
Pause before reserving if the name may imply a regulated activity, the Thai and English forms are not genuinely aligned, a foreign-ownership route is unresolved, or the documents needed for incorporation will not be ready in time. In those cases, validate the issue first and reserve only once the DBD result can move directly into the filing sequence.

Frequently asked questions
Can a reserved name be used for any Thai company type?
The DBD reservation rule describes use for a partnership or company registration, but the actual filing must still match the chosen vehicle and its current registration requirements. Confirm the entity type before submitting the name.
Does DBD name acceptance protect a trademark?
No. A DBD reservation is a company-register process. Trademark rights, domain availability and sector naming rules require their own checks and may affect whether the name is commercially safe to use.
