11 * We're sanitizing EU tax ids. Stripe expects a prefixed tax id (ATU12345678),
12 * but users might not realize this and enter only the numbers (12345678) without the
13 * country code prefix.
14 *
15 * Our sanitize function should handle 3 cases:
16 * 1. take an un-prefixed tax id (12345678) and add the country prefix to it (ATU12345678)
17 * 2. take a correctly prefixed tax id (ATU12345678) and just pass it through
18 * 3. take a non-EU tax id and just pass it through
