D-U-N-S number request stuck / company not found in Apple's D-U-N-S lookup

Organization enrollment requires a Dun & Bradstreet D-U-N-S number whose legal-entity details exactly match your registration documents. New numbers take up to ~5 business days to issue, then up to 2 more weeks to propagate into Apple's systems. Mismatched legal names (missing 'LLC', abbreviations, old addresses) cause silent lookup failures.
