How this service works
Validate a 13-digit Thai national ID or company tax ID by its checksum and format it (x-xxxx-xxxxx-xx-x). Checks format only; it does not look up whether the ID was issued. Query: ?id=1101700230708
Output
Returns whether the 13-digit Thai national ID or company tax ID passes checksum validation and its properly formatted representation as x-xxxx-xxxxx-xx-x. Does not confirm the ID was actually issued by the government — only structural/checksum validity is checked.
Example use cases
KYC pre-check for Thai users
“Before we save this customer's profile, can you verify that the Thai ID number 3100600215821 passes checksum validation and format it correctly?”
Invoice tax ID verification
“I have a Thai company tax ID from a vendor invoice — 0105542085767 — can you check if the format and checksum are correct before we process payment?”
Form input validation in onboarding
“A user entered 1-1017-00230-70-8 as their Thai national ID during sign-up. Can you validate whether it's a real ID checksum-wise and give me the canonical formatted version?”
Technical details
Endpoint
GEThttps://api.thaikit.dev/validate-id?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, offline-style checksum and format verification of Thai national IDs or company tax IDs — for example during form validation, KYC pre-screening, or invoice processing. It is not a government registry lookup, so it cannot confirm whether an ID was actually issued, but it reliably eliminates invalid or mistyped numbers.
Side effects
- ID is not 13 digits after stripping spaces and dashes — returns invalid format error
- Checksum digit does not match computed value — returns checksum failure
- Non-numeric characters other than dashes/spaces provided — returns format error
- Missing or empty id query parameter — returns bad request
