Hi @MikuMikuBeaaam,
Welcome to Microsoft Q&A forum.
I am sorry for the inconvenience you might have. Based on your sharing, it is taxing to ensure all your account details are accurate, only to be met with a persistent error message stating that your information does not match.
To resolve this discrepancy, please follow the troubleshooting steps outlined below:
Step 1: Verify regional and profile consistency
The age verification system requires a perfect match between your legal verification method and your digital profile.
- Log into account.microsoft.com and navigate to "Your Info."
- Confirm that your Country or region is set strictly to South Korea.
- Ensure your Date of Birth exactly matches the identification you are using for the I-PIN/PASS verification.
Step 2: Allow for server propagation (wait 24–48 hours)
When you modify a birth date on a Microsoft account, the change will be shown save successfully on the web, but it can take 24 to 48 hours for that data to synchronize with the Xbox Live gaming servers. If you attempt to verify your age immediately after changing your profile, the system will likely still see your previous data, triggering the mismatch error.
Step 3: Clear browser cache or use incognito mode
Your web browser may be storing "cookies" or cached data from your previous failed attempts.
- Open a new InPrivate window.
- Navigate directly to the 연령을 확인할 때 로그인 오류가 발생합니다. | Xbox Support. (Kindly refer to the Korean link since you mentioned you're in South Korea. Please let me know if you need the English link)
- Attempt the verification process again to ensure the system pulls fresh data from your account.
Step 4: Check for Family safety Interference
If your account was ever flagged as a "child" account, it might still be restricted even if you are now the only member of your Family Group.
- Visit family.microsoft.com.
- If your account is listed as a member rather than an organizer, or if there are lingering restrictions, the age verification may fail regardless of the birth date provided.
If the issue remains unresolved after you have completed these steps and allowed 48 hours for the system to synchronize, I highly recommend reaching out to Xbox Support directly for further investigation. Their specialized team can manually review your account's verification status and address any persistent regional data mismatches that may be preventing your access.
