ID number and personal data format test

The rules are the same as those used by EnjoyPDF secure redaction: where a check is possible, numbers are validated by check digit or date to reduce false positives. The text is processed only in your browser.

● Runs locally · no upload

Please do not paste real personal data. This tool sends no data, but your clipboard and browser history may still keep traces.
