I added my phone to my DUNS listing, still no validation. Why?

Some Certificate Authorities (especially Sectigo and DigiCert) may ask you to update or add your phone number to your company’s DUNS listing, as a part of your Business or Extended Validation process.

After you have contacted Dun & Bradstreet and added your phone number to your company’s DUNS listing, it may take between 5 and 40 days for Dun & Bradstreet to make your DUNS listing update available to the public. When you talk to Dun & Bradstreet over the phone, they may tell you that they added or updated your phone number. However, they only initiated process. Your phone number will appear on the Dun & Bradstreet website (https://www.dandb.com/) in about 5 to 40 days after that.

You will know that your DUNS listing has been truly updated, only when you get an email message from Dun & Bradstreet saying that your DUNS profile has been updated successfully. Your phone number will start appearing on your DUNS listing only after you get this email from them. Also, Certificates Authorities (such as Sectigo and DigiCert) can verify your phone number based on your DUNS listing only when your phone number is publicly available. That’s why you or we should contact the Certificate Authority requesting them to check your DUNS listing only after you get that confirmation by email.

In the past, we asked the Validation Department representatives from Sectigo and DigiCert to contact Dun & Bradstreet directly, and check our customer’s phone number with Dun & Bradstreet. We did that after our customers told us that they added or updated their phone number on their DUNS listing. Each time, Sectigo and DigiCert were told by the Dun & Bradstreet representatives that our customers’ DUNS listing update is “in progress” and “has not been completed yet”, and were advised to get back to Dun & Bradstreet when the customers receive an email message from Dun & Bradstreet which confirms them that their DUNS listing was updated.

If 5-40 days is too much to wait, we recommend you to go with other methods of validating your company and phone numbers, such as providing a legal letter written by a notary, an attorney, or a certified public accountant. This method will allow you to pass the Business or Extended Validation within 1-2 days.
