In today’s globalized world, businesses that want to expand internationally often choose to use a DUNS number. This code, issued by Dun & Bradstreet (D&B, USA), is especially useful for import-export companies in Vietnam.
The DUNS number is also very important for Vietnamese tech and software companies that want to work with global tech giants like Apple, Google, and Facebook. It’s required if they want to publish apps on platforms like the Apple Store or Google Play.
In the article below, GLA will explain what the DUNS number is, its benefits, and how we offer full support for registering it.
