Thai ID Generator & Validator
Generate valid 13-digit Thai ID card numbers (correct checksum) for testing forms and software — plus a validator. All in your browser.
Generated in your browser — nothing is sent.
About this tool
Developers and QA teams often need fake Thai ID numbers to test a system, but using someone's real number is both inappropriate and illegal. This Thai ID number generator creates checksum-valid 13-digit numbers in one click — safe and convenient for testing work.
The key thing to understand is that the numbers are not real people's identities. They are randomly generated only to match the checksum formula of a 13-digit Thai national ID. They are meant strictly for software testing and should never be used to impersonate anyone or to carry out any kind of transaction.
The tool does two things:
- Generates numbers that pass the checksum, ready to copy into a test form or database
- Validates existing numbers, checking whether the final digit matches the weighted formula, which helps catch mistyped entries
Everything runs in your browser, with no numbers stored or sent anywhere. It is free with no signup and opens on phone or desktop right away. It is perfect for testing registration forms, identity-verification flows, or data-validation logic — all without touching anyone's real information.
Click generate for your first number and drop it into the system you are building, or paste a number you already have into the validator to confirm it is correct.

Frequently asked questions
- Are the generated numbers real people's IDs?
- No. They are randomly generated to satisfy the checksum formula only, and are not tied to any real person.
- What can I use them for?
- Testing forms, databases, or any system that requires an ID field, without using anyone's real data.
- How does the validator work?
- It computes the final digit using the weighted checksum of the 13-digit ID and tells you whether your number is valid.
- Is it free and safe?
- Free, no signup, and it runs entirely in your browser — no numbers are stored or sent anywhere.
