What exactly is a DUNS number?
DUNS (Data Universal Numbering System) is a unique 9-digit numerical identifier created by Dun & Bradstreet (D&B), a company specializing in business information. This number functions as a global "business ID" and is used to:
- Uniquely identify each business entity
- Validate the legal existence and information of a company
- Establish business relationships with major technology platforms
- Build trust and credibility in the business ecosystem
The main application distribution platforms, such as Apple and Google, require this number to verify the legitimacy of companies publishing content in their stores.
Flutter and the need for a DUNS number
As Flutter developers, we know that one of the great advantages of this framework is the ability to create cross-platform applications with a single code base. However, when it comes time to publish these applications, both the App Store and Google Play will request your DUNS number if you're registered as a company or organization.
We've noticed that many development teams encounter this requirement in the final stages of the project, which can cause unexpected delays in launching. Despite the efficiency that Flutter offers in development, this administrative process can become a bottleneck if not managed in advance.
The maze of obtaining a DUNS number
Obtaining a DUNS number can become a confusing and sometimes frustrating process. Many developers encounter these obstacles:
- Multiple websites offering the service with contradictory information
- Complex forms requesting detailed business data
- Long waiting times for verification (which can extend for weeks)
- "Premium" services that promise to speed up the process in exchange for fees
It's important to note that obtaining a DUNS number should be free, although Dun & Bradstreet offers additional paid services. Unfortunately, some intermediary companies try to monetize this process by taking advantage of developers' confusion and urgency.
Our recommendation: Start with Apple
Based on our experience uploading applications to the stores, we recommend starting the DUNS number acquisition process through Apple. The reason is simple: Apple offers a more direct and transparent process.
Apple collaborates directly with Dun & Bradstreet to facilitate this process through its own form integrated into the business developer registration process. This approach has several advantages:
- Simplified form designed specifically for developers
- Step-by-step guided process with clear instructions
- Faster response times
- Free DUNS number acquisition
- Avoids dubious intermediaries trying to charge for a free service
Once you've obtained your DUNS number through Apple, you can also use it for your Google Play registration, thus leveraging the same identifier for both platforms and publishing your Flutter applications without impediments.
If you have questions about this process, need help obtaining your DUNS number, or face difficulties during your application registration, don't hesitate to contact us. Our team has extensive experience in publishing applications on different platforms and we'll be happy to advise you so you can complete this process in the simplest way possible
