Check Car Plate Checksum: Check

📖 Frequently Asked Questions (FAQs)

What makes a car plate checksum invalid?

The plate does not follow the pattern:
1–3 letters (prefix) + 1–4 digits + 1 letter (checksum)

Even if the format looks correct, the last letter (checksum) might not match the calculated value.
This happens if:

• Someone simply made up a plate without calculating the checksum properly.
• A typo occurred when writing the plate.
• An old plate was misread or tampered with.

Why does the checksum matter?

It’s a safeguard to prevent mistakes and fraud, similar to a check digit on a credit card or barcode.
It ensures that a valid plate can be verified algorithmically without consulting a central database.

Is this tool official?

This tool is not affiliated with LTA. It helps you quickly check validity based on current formats and rules. Always double-check with official sources if needed.

Does it work for motorcycles and commercial vehicles?
