How to Get a DUNS Number for Your US Business

A Data Universal Numbering System (DUNS) number is a unique nine-digit identifier used to verify a business’s existence. U.S. businesses often need a DUNS number when registering for federal programs, applying for grants, or working with certain vendors. Although the DUNS number itself is free, many business owners experience delays because they skip required steps or submit information that cannot be verified.

The Data Universal Numbering System, aka DUNS, was established in 1963 by Dun & Bradstreet. This system was introduced to identify businesses as

Step 1: Check If Your Business Already Has a DUNS Number

Before applying, search the official database to see if your business already has a DUNS number. Many businesses are surprised to find one already exists. Claiming an existing record as faster than creating a new one. If you already have a DUNS number, you can claim that by signing in to the official site.

Step 2: Prepare Your Business Information

If you do not already have a DUNS number, you must apply for one. To start with, please gather the exact information shown on your state registration:

• Legal business name
• Physical business address
• Entity type (LLC, Corporation, etc.)
• Business phone number

Note that all information shared by you should match the existing state record.

Step 3: Submit the Free DUNS Application

Apply for a DUNS number using the official free application. During the process, you may see optional paid services. These are not required to receive a DUNS number. To submit the application, one must register on the site.

Step 4: Complete the Verification Process

After submission, verification may occur automatically or require follow-up. This can include:

• A phone call to the business number
• A request for state registration documents
• Address confirmation

Step 5: Receive and Save Your DUNS Number

Why DUNS Application Get Delayed

DUNS applications are delayed when the information submitted cannot be verified against existing public and commercial records. In most cases, delays happen because applicants skip the record-check step or submit details that do not match state filings.

Applying Without Checking for an Existing DUNS Number

Many businesses already exist in the system due to prior registrations, licenses, or vendor relationships. Applying for a new DUNS number without checking first can create duplicate records and pause the process.

Business Information Does Not Match State Records

Even small differences, such as abbreviations, missing suite numbers, or outdated addresses, can prevent verification. State registration records are the primary reference point.

Duplicate Business Records

Some businesses already appear in external business databases due to prior registrations, licensing, or filings. Applying without confirming whether a record already exists can result in duplicate entries and delays.

Verification Requests Are Missed or Ignored

Some applications require additional verification, such as a phone call or document request. Delays often occur when businesses do not respond promptly.

Final Words

Getting a DUNS number does not require payment or special services, but it does require accuracy and patience. Most issues arise when applicants skip steps or submit information that does not match state records. By checking for existing records, preparing accurate information, and responding promptly to verification requests, businesses can obtain a DUNS number without unnecessary delays.
