Question

Company name not valid when registering for MS partenr

tlonist 5

When applying for microsoft partnership, I input my company's DUNS number.

It correctly identified my company, but the page says the retrieved company name is not valid. what should I do here? The company name is not something I typed, but retrieved and autofilled from DUNS input.

Hi @tlonist ,

Thanks for raising this issue—it's a common point of confusion during Microsoft Partner Center registration, especially when using a DUNS number to autofill company details.

When the Partner Center retrieves your company name from Dun & Bradstreet (D&B) via the DUNS number, it applies a set of validation rules to ensure the name meets Microsoft's formatting and verification standards. Even if the name is correct and officially registered, it may still be flagged as invalid due to one of the following reasons:

1. Formatting Conflicts with Validation Rules
Microsoft enforces specific rules for company names, such as:

No use of only special characters or repeated characters (e.g., “###” or “999”).
Avoiding standalone abbreviations like “LLC” or “INC” without additional context.
No domain extensions (e.g., “.com”) in the name. You can review the full validation criteria here.

2. DUNS Data Mismatch or Delay
Sometimes the DUNS data retrieved by Microsoft may be outdated or formatted differently than expected. If your company name includes symbols, abbreviations, or spacing that violates Microsoft’s rules, it may be rejected even though it’s valid in D&B.

3. Verification Status and Role Permissions
Only users with Global Admin or Account Admin roles can update legal business profiles. If your account is not authorized or pending verification, you may be restricted from editing the company name directly. In such cases, you’ll need to submit a support request with documentation showing the correct legal name. You can check it here.

Recommended Steps:

Go to Partner Center > Settings > Account Settings > Legal Info and attempt to update the company name manually.
If the update fails, create a support request and attach a HAR file or PSR showing the error steps.
Alternatively, use the “I don’t have a DUNS number” option to manually enter your company details and proceed with verification.
Ensure your domain and email match your company name and are not personal accounts, as this can also affect verification.

Let me know if you need help navigating the Partner Center or preparing documentation for support. If not, please consider interacting with the system accordingly so I can close this case!

Thanks for taking time to answer my question.

Our company name 'Sherpas Co.Ltd,.' doesn't seem to violate the mentioned rule

It also doesn't seem to violate microsoft duns rule.

Go to Partner Center > Settings > Account Settings > Legal Info

this shows no information at all, what did I miss?
some screenshots to help understand. First one shows there's nothing shown in the legal info, unlike the link(https://learn.microsoft.com/en-us/windows/apps/publish/store-business-verification-reqs#:~:text=Ensure%20you%20are%20in%20the%20Developer%20tab.)

secondly, there's nothing shown for the workspaces. is this normal?

If your workplace is empty, that's probably because you haven't set up a developer account, or the set up didn't go through properly. I suggest referring to this page https://learn.microsoft.com/en-us/windows/apps/publish/partner-center/open-a-developer-account?tabs=individual to set up your individual or company account accordingly.

Legal Info section coming up empty usually means that your account vetting status is rejected and it might be possible that you are locked out of submitting revisions.

I suggest going through your submission process again. If the legal info section still comes up empty again, I suggest opening a ticket here: https://support.serviceshub.microsoft.com/supportforbusiness/create?sapId=bc9d4067-7218-61b9-1d2c-68ae591acf9d

You could also consider setting up a new developer account with correct information. you can also check whether your account meets the requirements here: https://learn.microsoft.com/en-us/partner-center/enroll/mpn-create-a-partner-center-account

Thanks. I found out that my company name [Sherpas Co.,Ltd.] contains a comma(,) that is not allowed in the company name? https://learn.microsoft.com/en-us/partner-center/customers/validate-names-addresses

Can this really be the case? I mean having a comma between Co. and Ltd. seemed common.

I don't think that is the case. You might want to try adding a space between Co., and Ltd. The validators might be sensitive to spacing like that. Since company's name is a sensitive area, it's best that you open a support ticket for this matter.

Thanks for answering.

Turns out it was the case! The company name warning does not appear anymore.
But now another validation problem occured.

As can be seen from the screenshot, the page says it can't validate the pre-filled address. Clicking either 'Enter a different address' or 'Continue' does not do anything and the popup disappears.

What might be the problem in this case?

Hi,

I suggest not sharing your full address here for privacy. For Partner Center, ensure the country follows ISO rules (e.g. US for United States, KR for South Korea). If the form expects the full country name, use the official full form.

For the expected address structure, refer to Microsoft’s validation template (field layout) shown in the official doc:
Validate an address (Partner Center API)

That page shows the template-style fields you should map to (e.g. addressLine1, addressLine2, city, state, postalCode, country). I suggest referring to them as guidance.

If the form still fails after using ISO country codes, continue privately with Microsoft Support rather than pasting the full details publicly. You can find more information on this part here https://learn.microsoft.com/en-us/partner-center/support/report-problems-with-partner-centerOr you can create a ticket here directly https://support.serviceshub.microsoft.com/supportforbusiness/create

The country name was chosen from the dropdown list, hence using Korea instead of KR is correct. I want to file a ticket directly to MS, but creating the ticket requires me to have a workspace, which I'm not able to make due to the unfinished enrollment process. This is a frustrating catch-22 situation here.

This looks like the Partner Center address‑validation dialog failing to apply changes. Try these few steps:

Open Partner Center in an InPrivate/Incognito window with extensions disabled; if possible, try a clean Edge/Chrome profile.

Clear cookies/site data for partner.microsoft.com and login.microsoftonline.com, then hard‑refresh.

Temporarily switch Windows/browser display language to English (United States), retry, then switch back.

Re‑select Korea in the country dropdown and re‑enter the address exactly in KR format (province/do, city/si, 5‑digit postal code). The validator uses ISO2 ‘KR’ rules behind the scenes.

If the popup still does nothing, contact Microsoft support without a workspace via Contact us → Ask Copilot and ask to open a Partner Center enrollment ticket.

If that doesn't work also, I suggest sending a ticket here https://support.serviceshub.microsoft.com/supportforbusiness/create?sapId=bc9d4067-7218-61b9-1d2c-68ae591acf9d
