How to Get a D-U-N-S Number for Free

Why You Should Never Pay for a D-U-N-S Number

Third-party services charge $50 to $300 for something Dun & Bradstreet (D&B) provides at zero cost. The Data Universal Numbering System (DUNS) number is free to obtain directly from D&B. Paying a middleman buys you nothing except a faster form submission - and Apple offers its own expedited path that beats even that.

This guide walks you through every free method, step by step.

What Is a D-U-N-S Number?

A DUNS number is a unique nine-digit identifier that D&B assigns to a single business entity. It links to a profile containing your company’s name, address, phone number, workforce size, and industry classification.

Apple requires this identifier for any organization enrolling in the Apple Developer Program. Without one, you can only enroll as an individual developer, and your personal name replaces your company name on every App Store listing.

Method 1: Request Through Apple (Fastest Free Option)

Apple partnered with D&B to speed up the process for developers. This is the quickest free route - most requests resolve within five business days.

Step 1: Check If You Already Have One

Visit the D-U-N-S Number lookup tool on Apple’s developer site. Enter your legal business name and address. If your company already has a number, you will see it here.

Step 2: Submit a Free Request

If no number exists for your organization, the same lookup tool lets you request one. Click the link to submit your information to D&B through Apple’s portal.

You will need the following details:

• Legal business name
• Headquarters address
• Mailing address (if different)
• Phone number
• Contact name and title
• Number of employees at your location

Step 3: Wait for Confirmation

D&B will email your new DUNS number, typically within five business days. Save this email - you will need the number for enrollment.

Step 4: Enroll in the Apple Developer Program

Once your number is active and your organization appears in D&B’s database, proceed with enrollment. Make sure your company name and address match the D-U-N-S record exactly. Even small differences like “LLC” versus “L.L.C.” can trigger rejection.

Method 2: Apply Directly Through D&B

You can also request a DUNS number from D&B’s own website. This method works for any purpose, not just Apple enrollment.

How to Apply

1. Go to the D&B website and navigate to their DUNS number request page.
2. Fill in your business details - the same information listed above.
3. Submit the free application.

Processing Time

The standard timeline is up to 30 business days. This is significantly slower than the Apple route. Choose this method only if you need the number for government contracts, grants, or vendor registration rather than developer enrollment.

Expedited Options From D&B

D&B offers paid expedited processing for those who need a number within 24 hours. Skip this. Unless you face an urgent government contract deadline, the free Apple path delivers faster results for app developers.

Method 3: Federal Government Contracts

If your business bids on federal contracts, you can receive a DUNS number within 24 hours at no cost. The federal registration process prioritizes speed because government procurement depends on these identifiers.

Register through the System for Award Management (SAM) portal, which handles DUNS assignment as part of vendor enrollment.

What Happens After You Get Your Number

Your DUNS number unlocks several capabilities that matter for App Store Optimization (ASO).

Professional Developer Identity

Your company name appears on every app listing instead of a personal name. Users trust recognized business names more than individual developer names, which directly improves your conversion rate.

Team Access in App Store Connect

Organization accounts unlock team-based access to App Store Connect. You can assign roles for marketing, development, and finance - essential for managing metadata optimization across multiple titles.

Keyword Advantages

The App Store search algorithm indexes your developer name. If your business name contains relevant terms, those words contribute to your keyword rankings. This hidden advantage starts at enrollment.

Portfolio Management

A single organization account can host multiple apps under one brand. This lets you build authority across your portfolio, share credibility from app ratings, and run a unified ASO strategy that platforms like ASODOG help you track.

Common Mistakes That Delay the Process

Name Mismatches

The legal name on your DUNS record must match your Apple Developer enrollment exactly. Verify the spelling, punctuation, and entity suffix before submitting.

Outdated Address Records

If your company has moved, update the DUNS record with D&B before enrolling. Stale information causes verification failures.

Duplicate Applications

Check for an existing number before requesting a new one. D&B assigns numbers per physical location - your business may already have one from a prior registration.

New Business Not in Database

Recently formed companies may not appear in D&B’s system yet. Submit a new request and allow time for the record to propagate.

Free vs. Paid: What You Actually Get

Option	Cost	Timeline	Best For
Apple lookup tool	Free	5 business days	iOS developers enrolling as organizations
D&B standard request	Free	Up to 30 days	Government vendors, general business use
Federal SAM registration	Free	24 hours	Government contract bidders
D&B expedited service	$229+	1-5 days	Urgent non-Apple needs only
Third-party services	$50-$300	Varies	Never recommended

The free options cover every legitimate scenario. No app developer needs to spend money on this.

International Developers

D&B operates in over 200 countries. Developers outside the United States can request a DUNS number through D&B’s international offices. Processing times vary by region, but the Apple lookup tool works globally and remains the fastest free path for developer enrollment.

Keeping Your D-U-N-S Number Current

A DUNS number does not expire, but the associated business record requires maintenance. Update D&B whenever your company changes its legal name, address, or phone number. Outdated records can block Apple Developer Program renewals and cause issues during app store localization efforts across multiple markets.

Next Steps

1. Search for your existing number using Apple’s free lookup tool.
2. Request a new number if none exists - through the same tool.
3. Wait for the confirmation email from D&B.
4. Enroll in the Apple Developer Program with matching business details.
5. Set up your organization account in App Store Connect and start optimizing your app listings.

The entire process costs nothing. Save your budget for building great apps.
