Codex and Claude from Mainland China: Access Checks for Work

Mainland China is absent from the published OpenAI API and Anthropic access lists. A reseller account does not establish an approved working arrangement.

If you need an AI coding tool for work in mainland China, settle access and data handling before setting up payment. Otherwise you may buy a subscription that the intended user cannot properly access, or send company code to a service the company has not approved.

Separate three decisions

DecisionQuestion to answer
Service eligibilityIs your actual location and account covered? Mainland China is not listed for OpenAI API or Anthropic’s direct services.
Product entitlementDo you need a chat account, an IDE/terminal tool, or an API project? Verify the exact product in the agreement.
Company dataMay this code or document be sent to that provider, under those retention and access settings?

For an employer-provided account

Ask IT or procurement for the service name, provider, authorized user locations, support contact and billing owner. A corporate gateway or third-party platform may have its own contract and product coverage; do not assume it is equivalent to a direct consumer account, or that an overseas server changes the user’s eligibility.

Use a named account assigned to you. Confirm what happens when you leave the company, whether the organization can view work, and where the repository is processed. Start with a non-sensitive sample task until the correct workspace is clear.

If you are choosing for yourself

  1. Check the provider’s current location and product rules. If the service does not cover you, compare tools that explicitly do.
  2. Avoid prepaid annual commitments until you can sign into your own eligible account and complete the task you need.
  3. Price the actual work: subscription allowance, separately billed API calls and any platform fee.
  4. Keep the invoice, terms and cancellation process. A reseller’s promise of permanent access is not a substitute for these.
