The error is caused by the ongoing currency transition for Bulgaria in Microsoft storefronts.
Bulgaria is moving from Bulgarian lev (BGN) to euro (EUR) across Microsoft platforms. As part of this change:
- All consumer transactions across Xbox and Windows (including gamertag changes and other paid actions) are being migrated from BGN to EUR.
- Paid transactions in Bulgarian lev are temporarily disabled. When a product or service is still configured in BGN, attempts to buy it show a message that the currency is not supported or that the product is temporarily unavailable.
- Microsoft is republishing products in EUR in phases. Republishing started in early January 2026 and is expected to complete by late February or early March. Until the specific offer (such as the gamertag change) is republished in EUR, purchases from Bulgarian accounts can fail with this message.
Actions:
- Confirm the account region is set to Bulgaria and that no region change is pending or blocked (for example, by recent region changes or account suspension). If there are region‑change issues, use the guidance under “Troubleshooting issues when changing your region in Microsoft Store.”
- If the account is correctly set to Bulgaria and in good standing, the issue is not something that can be fixed locally; it depends on when the specific Xbox/Microsoft Store offer is republished in EUR for Bulgaria.
- For status or to escalate the specific offer (gamertag change), contact Microsoft Store/Xbox support and reference that the account is in the Bulgarian storefront and is affected by the euro transition. Use the Microsoft Store or Xbox support contact options listed for account‑billing or purchase issues.
Until the republishing for that offer is complete, changing the gamertag through paid purchase from a Bulgarian storefront may remain unavailable.
