# BC PHN Validator

Check a BC Personal Health Number against its check-digit rule.

Canonical HTML version: https://pharmflow.io/tools/phn-validator

A BC Personal Health Number has ten digits. It starts with 9 and ends with a mod-11 check digit.

Enter a number below to verify its structure. A valid structure does not confirm identity or coverage.

The check uses the same British Columbia Personal Health Number rule as PharmFlow check-in.

## Does a valid PHN confirm coverage?

No. This tool checks the structure of the number only. It does not confirm identity, registration, or eligibility.

## Does it work for other provinces?

No. The rule is specific to British Columbia Personal Health Numbers.

## Is the number sent to a server?

No. The check runs in your browser. Nothing you enter is uploaded.
