What checksum does this use?

It uses the standard Israeli ID checksum, a Luhn variant — each of the 9 digits is multiplied alternately by 1 and 2 starting from the left, two-digit products are reduced by 9, and the number is valid when the total is divisible by 10.

How accurate is the result?

A valid checksum confirms the number is well-formed, but it does not mean the number is issued or belongs to anyone — it has no link to any government database.

Is my ID number sent anywhere?

No. The validator is privacy-first — all processing happens locally in your browser and the number never leaves your device.

Israel Teudat Zehut (ID) Validator

Israel Teudat Zehut (ID) validator

Validate an Israeli Teudat Zehut (תעודת זהות) number. The tool pads shorter numbers to 9 digits, then applies the standard Israeli checksum — a Luhn variant that weights digits alternately by 1 and 2 and checks that the total is divisible by 10.

It is privacy-first: nothing leaves your browser. A valid checksum only means the number is well-formed — it carries no link to any government database and the number encodes no date of birth or gender.
