One page for each genuinely different question
We separate different user intents — for example, cost, processing time and Apple organization verification — while keeping wording variants of the same question on one canonical page. This makes the site easier to navigate and avoids creating thin pages that repeat the same answer.

Read guide →Frequently asked questions
Where should I start if I do not know whether my company has a D-U-N-S number?
Start with a D-U-N-S lookup before submitting a new application.
Are Apple and Google D-U-N-S requirements identical?
No. Each platform has its own organization-verification workflow, timing and documentation requirements.
Should every D-U-N-S question have a separate page?
No. These guides separate distinct user intents; closely related wording is kept on the same page to avoid duplicate content.
