Where to start
Use the official D&B route or Apple’s official organization lookup. Have the registered name, address and work contact details ready.
If you find multiple or outdated records
Identify the correct legal business and location. Ask D&B about ambiguous matches or updates instead of assuming a similarly named company is yours.
How we help

Frequently asked questions
Is MASTERSTAP Dun & Bradstreet?
No. MASTERSTAP is an independent assistance provider. Dun & Bradstreet issues and manages D-U-N-S Numbers. You can also approach D&B directly.
Can I get a D-U-N-S Number in 24 hours?
A 24-hour issuance cannot be guaranteed. Timing depends on existing records, document completeness, business verification and D&B processing. Tell us your deadline so we can assess your case before you proceed.
