Stuck on Store developer registration — Macao SAR has no state/province

Leave State/province empty if the form permits it; if submission requires a value, try Macao, then Macau, and finally MO as a form-validation workaround while keeping every other address field consistent with your official address documents.

Microsoft does not document an official State/province value for Macao SAR. MO is the documented ISO country/region code for Macao SAR—not a province code—so these are troubleshooting attempts rather than guaranteed profile values.^1^

Try these values in order

1. Leave State/province blank and submit, if the field allows it.
2. If it is mandatory or rejects the blank value, enter Macao.
3. If rejected, try Macau.
4. If text validation still fails, try MO. Partner Center has previously had registration validation issues where an abbreviation was accepted instead of a full state/province name, although that case did not specifically involve Macao.^2^
5. Do not select an unrelated province or change the country/region. The remaining address details should match your identity or legal documents because profile information can be verified, and changing key details can restart verification.^3^

If none of those values is accepted

Because you have completed ID verification and are using a personal email address, this may be the new Individual developer onboarding flow:

• Email [Email]. Microsoft designates this mailbox specifically for issues with the new individual-developer onboarding process.^4^
• If this is a Company account or another enrollment flow, use the Windows developer support link provided by the Store onboarding documentation: https://aka.ms/windowsdevelopersupport.^5^
• If you can access Partner Center, select Help (?) → Contact Support → Create support request.^6^

Include these details privately in the request:

• Country/region: Macao SAR
• Blocked field: State/province has no valid option
• Correlation ID and exact UTC timestamp from the failure
• Account type: Individual or Company
• Confirmation that ID verification has passed
• Browser and version
• Values attempted: blank, Macao, Macau, and MO
• A screenshot showing the field and validation message, with email and other personal data redacted
• A request to correct the address-field validation or complete the enrollment review

If the page offers Collect more information, save the diagnostic report, review it for personal information, remove anything unnecessary, and attach it to the private support request.^7^

Do not post the correlation ID, diagnostic report, or unredacted account details publicly.
