OpenAI 403 country_region_not_supported

403 country_region_not_supported

OpenAI is blocked from your country or region. This is enforced at the network layer based on your request's originating IP. The list of supported countries is maintained at platform.openai.com/docs/supported-countries.

What you see when this happens

HTTP 403 with message: 'Country, region, or territory not supported'
Works when tunneling through VPN to a supported country
Fails from certain IPs/regions consistently
Same key works elsewhere

Common causes

OpenAI service unavailable in your country

Sanctions, regulatory restrictions, or business decisions limit availability.

Cloud provider IP mapped to unsupported region

Your cloud region's IP block may resolve to a blocked country in OpenAI's geo-IP database.

VPN or proxy routing through unsupported region

Ironically, VPNs can trigger the block if their exit is unsupported.

How to fix it

Deploy from a supported region

Move your app deployment to a cloud region in a supported country (US, most of Europe, most of Asia-Pacific). This is the proper fix for production apps.

Route through a proxy in a supported region

For temporary access, deploy a lightweight proxy in a supported region and route OpenAI API calls through it. Note: this may violate OpenAI's ToS depending on your intent.

Use Azure OpenAI in a supported region

Azure OpenAI has different regional availability from direct OpenAI API. Deploy Azure OpenAI in a region that's available for your country's accounts.

Use alternative providers

Anthropic Claude, Google Gemini, or Mistral may be available in your region even when OpenAI isn't. Multi-provider architecture (see B6) makes this substitution transparent.

How to prevent it

Verify your deployment region against OpenAI's supported countries list before shipping
Design multi-provider architecture from day one for regional flexibility
Monitor 403 country errors — sudden appearance may signal IP block changes

Frequently asked questions

Which countries are unsupported?

The list changes over time — check platform.openai.com/docs/supported-countries for the current list. Common unsupported: China, Russia, Iran, Cuba, North Korea, Syria, and certain other sanctioned regions.

Can I appeal a country block?

Country blocks are enforced by OpenAI based on their business/legal decisions. Individual appeals aren't typical. For enterprise arrangements, contact OpenAI sales — some enterprise contracts have wider geographic reach.
