For government contracting, which identifier is commonly required for vendors?

• A. Passport number
• B. DUNS number
• C. Social Security Number
• D. Employer Identification Number

Answer: (B)

In government contracting, vendors are identified by a unique business identifier used across procurement systems. The DUNS number serves that role: a unique nine-digit code assigned to each business by Dun & Bradstreet and used by federal procurement processes to register, verify, and track vendors. This standard helps agencies link registrations, bids, contracts, and payments to the correct entity, ensuring consistency across departments. A passport number or Social Security Number relate to individuals, not organizations, and aren’t appropriate for corporate vendor records. An Employer Identification Number is a tax identifier for a business, but the widespread, cross-agency identifier used in vendor data and contracting workflows is the DUNS number, which is why it’s the best answer.
