Country code, two check digits, and a country-specific account number, validated with the ISO 7064 mod-97 checksum and per-country length rules.
One pattern, high confidence, NO supporting keywords required. The mod-97 checksum is strong enough that Microsoft trusts the bare match. This is the counter-example to "high confidence needs supporting evidence": when the maths does the validating, context is optional.
