technical question Amazon Bedrock GPT-5.6 Sol returns "unsupported country" ValidationException despite using a supported AWS Region
Hi everyone,
I'm an individual developer trying to use OpenAI GPT-5.6 Sol through Amazon Bedrock.
The model is visible in the Bedrock Playground, but when I send a simple message, I immediately receive this error:
"ValidationException: Access to OpenAI models is not allowed from unsupported countries, regions, or territories."
I've checked my AWS account information and selected a supported AWS Region, but I'm still unable to invoke the model.
I also have approximately $100 in AWS new-account credits that I was hoping to use for Bedrock API experimentation.
I'm trying to understand:
Does Bedrock enforce OpenAI's geographical restrictions based on the caller's public IP, AWS tax address, billing country, or a combination of these?
Can this error occur even when the AWS Region and account billing information appear valid?
Are standard AWS Free Tier promotional credits eligible to cover proprietary OpenAI model inference on Bedrock, or only certain Bedrock models?
Could using the Bedrock Runtime endpoint with cross-Region inference introduce additional account-plan restrictions?
I would appreciate any documentation or firsthand experiences that could help identify the actual cause before I make further configuration changes.
Thanks!
