Why this rule existsrationale
The alternate identifier is optional and strengthens verification when it is present, but a number with no type is a number nobody can look up — the registry rejects the pair rather than storing half of it. It usually happens when a DUNS number is added helpfully, from a procurement record that never carried a type field.
How to fix itremediation
Set altBusinessIdType to the register the alternate number came from — DUNS for Dun & Bradstreet, GIIN for the IRS FATCA register, LEI for a legal entity identifier. If you do not have one, clear both fields rather than sending a bare number. Done when either both fields are populated or neither is.

Notesnotes
The field is optional and validated only when present, which is why this is LOW rather than BLOCKING — but it will reject the whole brand submission, so it costs a round trip like any other field error.
