# banking_set_owner_tax_identifier

Files one beneficial owner's Social Security Number or ITIN against a banking application. The whole number goes to the secret store and only its last four digits are recorded, which is all the response returns. Ask the person which of the two they hold and pass it as kind: an ITIN starts with 9 and an SSN never does, and a mismatch is refused. Ask for the number directly and pass it once — never guess it, never read it back to them, and never repeat it in your own message. The owners section cannot be completed without one for each assessed owner.
