What Is a DUNS Number?
A DUNS Number — Data Universal Numbering System — is a unique nine-digit identifier assigned to businesses by Dun & Bradstreet. It functions as a universal business identifier that is used to track a company’s commercial credit history, verify its business information, and facilitate transactions with government agencies, financial institutions, and large corporations that require verified business identification.
A DUNS Number is required for businesses that want to apply for federal contracts or grants through SAM.gov — the System for Award Management — which is the primary federal government database for contractor registration. Many state government contracting programs, international trade platforms, and large private sector procurement systems also require a DUNS Number as part of the supplier qualification process. Manay CPA manages the DUNS registration and advises on the downstream registrations that depend on it.
Steps
Information Review
We review your business’s legal name, address, structure, and EIN to ensure all information is accurate and consistent before initiating the DUNS registration — because discrepancies in business information can delay the issuance process.
DUNS Registration
We submit your DUNS Number request to Dun & Bradstreet through the appropriate channel with accurate, complete business information and manage any follow-up correspondence through issuance of your nine-digit DUNS Number.
SAM.gov Registration
For clients pursuing federal government contracts or grants, we coordinate your SAM.gov registration — which requires a DUNS Number and must be renewed annually — and ensure that your federal business profile is complete and current.
Dun & Bradstreet Profile
We advise on maintaining an accurate and complete Dun & Bradstreet business profile — including updating information when your business name, address, or ownership changes — so your DUNS record reflects your current business accurately.

Federal Government Contracting Requires a DUNS Number and SAM Registration
Any business that wants to bid on federal government contracts, apply for federal grants, or receive federal financial assistance must be registered in SAM.gov — the System for Award Management. SAM.gov registration requires a DUNS Number as a prerequisite. Without both a DUNS Number and an active SAM.gov registration, a business is ineligible to be awarded any federal contract or grant regardless of the quality of its proposal or qualifications.
SAM.gov registrations must be renewed annually. A SAM.gov registration that lapses — even for a single day — can disqualify a business from receiving contract awards or grant payments until the registration is renewed. Manay CPA manages SAM.gov renewals for clients pursuing government work and alerts them well in advance of their renewal deadline.
The DUNS Number Builds Your Business Credit Profile
Dun & Bradstreet uses the DUNS Number as the anchor for a business’s commercial credit profile — the Dun & Bradstreet Business Information Report and the PAYDEX score that many commercial lenders, insurance underwriters, and large corporate procurement departments use to evaluate a business’s creditworthiness and reliability. Establishing a DUNS Number is the first step in building a documented commercial credit history that is separate from the owner’s personal credit.
Businesses that want to qualify for trade credit, net payment terms from suppliers, commercial lease financing, or supplier registration with large corporations benefit from establishing their DUNS profile early and maintaining a strong payment history that is documented in the Dun & Bradstreet system.
Accuracy of Business Information Is Critical
The DUNS Number is issued based on the business information submitted at registration — legal name, physical address, entity type, EIN, and principal contact. This information must match the business’s official records exactly. If the name on the DUNS record does not match the name in SAM.gov, which must match the name in the IRS system, the registration process will encounter errors that delay the issuance of a DUNS Number or the completion of the SAM.gov registration.
Manay CPA reviews all business information for consistency before initiating the DUNS registration, reducing the risk of information mismatches that create delays in the registration process.
Updating Your DUNS Record Is Required When Business Information Changes
When your business changes its legal name, moves to a new address, undergoes a change in ownership, or changes its legal structure, the DUNS record must be updated to reflect the new information. An outdated DUNS record can create mismatches in SAM.gov and in the databases of businesses and agencies that rely on Dun & Bradstreet data to verify your business information.
Manay CPA advises clients on when a DUNS record update is required and manages the update process to ensure that your business’s information is current and consistent across all platforms that depend on it.
Frequently Asked Questions about State Department of Labor Registration
Do I need a DUNS Number if I am not pursuing government contracts?
The DUNS Number is primarily required for federal contracting and grant applications through SAM.gov. However, many large private sector corporations — particularly in supply chain and procurement contexts — also require suppliers to have a DUNS Number as part of their vendor qualification process. It is also useful for building a separate business credit profile. If your business does business with large corporations or plans to pursue government work in the future, obtaining a DUNS Number is worthwhile.
How long does it take to get a DUNS Number?
Dun & Bradstreet typically issues DUNS Numbers within one to two business days for expedited requests. Standard processing can take up to five business days. If you need a DUNS Number as part of a SAM.gov registration for a pending contract opportunity, plan for the DUNS registration to precede the SAM.gov registration — SAM.gov processing can take an additional one to three weeks after the DUNS Number is issued.
Is the DUNS Number free?
Dun & Bradstreet offers DUNS Number registration at no charge for businesses that need it for federal contracting purposes. There is no fee for the basic DUNS Number. Dun & Bradstreet does offer paid services — such as business credit monitoring, enhanced business reports, and credit-building programs — that are separate from and not required for basic DUNS registration.
Does my DUNS Number expire?
The DUNS Number itself does not expire. However, your SAM.gov registration — which requires the DUNS Number — must be renewed annually. If your SAM.gov registration lapses, your business cannot be awarded federal contracts or receive federal grant payments until it is renewed. Manay CPA manages SAM.gov annual renewals for clients with active government contracting programs.
What is a PAYDEX score and how does the DUNS Number relate to it?
The PAYDEX score is Dun & Bradstreet’s business payment index — a score from 1 to 100 that reflects how promptly your business pays its bills relative to agreed payment terms. It is calculated based on payment history data reported by vendors and creditors to Dun & Bradstreet. The PAYDEX score is associated with your DUNS Number. Establishing a DUNS Number and paying vendors on time — ideally before the due date — builds a strong PAYDEX score that commercial lenders and corporate procurement departments use to evaluate your business’s creditworthiness.
