Israel Teudat Zehut (תעודת זהות) validator
How the Teudat Zehut (תעודת זהות) format works
- Format
- 9 digits with a standard Luhn (mod-10) check digit
- Example
- 039337423
Things to watch for
- Standard Luhn (mod-10) check digit over all 9 digits — IDs shorter than 9 digits are conventionally left-padded with leading zeros before the check is applied, so include any leading zero when entering yours
- Format + checksum only — a pass doesn't confirm the Teudat Zehut is currently issued or active
- A Teudat Zehut identifies a specific individual — this check runs entirely in your browser, so nothing you type is stored or transmitted
^[0-9]{9}$Israel’s Teudat Zehut (תעודת זהות) is the 9-digit identity number the Population and Immigration Authority issues to citizens and permanent residents, printed on the ID card and blue ID booklet and required for banking, healthcare, voting, and most government services — for example 039337423.
Many Teudat Zehut numbers were originally assigned with fewer than 9 digits, and older ones are still commonly seen written as 7 or 8 digits. The check digit, however, is always calculated over the full 9-digit form, so a shorter number needs to be padded with leading zeros before the standard Luhn algorithm — doubling every second digit from the right, summing the results, and requiring a total divisible by 10 — can confirm the final digit is correct. Drop that leading zero and an otherwise-genuine ID will fail the check.
How this validator works
This tool confirms the input is 9 digits and runs the standard Luhn algorithm over the full number, entirely in your browser. Nothing you type is sent to a server or stored.
What a pass doesn’t tell you
A pass confirms the 9 digits are internally consistent with the Luhn formula — not that the number was ever issued by the Population and Immigration Authority or that it’s currently active. A Teudat Zehut identifies a specific individual, so treat any number you check here with the same care as other personal ID data.
Scope: this page and tool cover Teudat Zehut format and Luhn checksum validation only — not Population and Immigration Authority registration or identity verification.

Teudat Zehut (תעודת זהות) FAQ
My Teudat Zehut only has 7 or 8 digits — how do I check it here?
Left-pad it with zeros until it's 9 digits long. Israel's Population and Immigration Authority calculates the Luhn check digit over the full 9-digit form, including any leading zeros, so dropping them will make a genuine ID fail this check.
Why does Israel use the same Luhn algorithm as credit cards for a national ID?
Luhn is a general-purpose check-digit method rather than something exclusive to payment cards, and the Population and Immigration Authority applies that same doubling-and-summing formula across all 9 digits of a Teudat Zehut.
Does a valid Luhn checksum confirm I'm registered with the Population and Immigration Authority?
No. It only confirms the 9 digits are mathematically consistent with each other — not that the number was ever issued or is currently active.
