Can this tool confirm an ID number belongs to a real person?

No. It checks the numeric format only (1–8 digits, not all-zero). It cannot query any government database or confirm a number is live or linked to anyone — that requires official verification.

Is my ID number sent anywhere?

No. The validator is privacy-first. All processing happens locally in your browser with no network requests — your ID number never leaves your device.

Kenya National ID Validator — Check ID Number Format

Q: Does the Kenyan ID number encode date of birth or county?

No. The Kenyan national ID number is a sequential numeric serial of up to 8 digits assigned by the Department of Civil Registration. It does not encode date of birth, county or gender, and there is no published check-digit algorithm.

The only deterministic, offline-verifiable rule is therefore the format: 1–8 numeric digits, not all-zero.

Privacy-first: everything runs in your browser with no network requests. This tool checks the format only — it cannot confirm an ID against any government database.
