not publicly documented for Business: the residency page in the Help Center (as of 2026-10-18) names as eligible "Eligible API customers and new ChatGPT Enterprise/Edu customers" (q5), the business data page "Eligible ChatGPT Enterprise, ChatGPT Edu, ChatGPT for Healthcare, and API platform customers" (q11); ChatGPT Business is not named in either. The pricing page lists data residency in ten regions only for the Enterprise plan. The sub-processor list (as of 2026-10-14) names processing locations for Business in the USA and other countries (including EU Member States), without a choice.

not publicly documented: the Help Center refers to sales for data residency and EKM ("You require advanced enterprise features (for example, data residency or EKM)"); the residency page does not name Teachers.

Help Center Data residency (as of 2026-10-18): "Eligible API customers and new ChatGPT Enterprise/Edu customers can choose to have in-scope customer content stored at rest in supported countries." Regions: Australia, Canada, Europe (EEA + Switzerland), India, Japan, Singapore, South Korea, UAE, UK, USA. Inference residency (GPU execution in the region) only for Europe (EEA + Switzerland), USA and UAE, and only with data residency activated in the same region. In scope: Memory, Code Interpreter/Data Analysis artefacts, conversations (text, image, voice), Custom GPTs, files, image generation inputs/outputs, incl. backups/replicas; new features only if listed. Outside the region, data from external integrations (Apps & MCP, Web Search), transient processing steps, workspace metadata and name, billing information and logins, among others, may be stored ("Certain categories of data may be stored outside the chosen data region"); CPU processing such as authentication, routing and analytics may run outside the region. Applies to newly provisioned workspaces; eligibility via sales; at no additional cost for Enterprise and Education.

Help Center Data residency (as of 2026-10-18): "new ChatGPT Enterprise/Edu customers can choose to have in-scope customer content stored at rest in supported countries"; Europe (EEA + Switzerland) is a supported region; inference residency for Enterprise/Edu with data residency activated (Europe, USA, UAE). Exceptions as for Enterprise (including external integrations, workspace metadata, billing information, logins). Eligibility via sales; at no additional cost for Education.

Help Center Data residency: "Eligible API customers ... can choose to have in-scope customer content stored at rest in supported countries". API documentation (Data controls, as of 2026-10-18): data residency is a project setting; "Contact our sales team to see if you're eligible for using data residency controls." Regions with their own endpoints: USA, Europe (EEA + Switzerland, eu.api.openai.com), Australia, Canada, Japan, India, Singapore, South Korea, UK, UAE; inference in the region only for the USA, Europe and the UAE, the other regions storage only; all regions except the USA require Modified Abuse Monitoring or Zero Data Retention. System data (account data, metadata, usage data without customer content) may be processed and stored outside the region. For models released from 2026-03-05, a 10% uplift applies on residency endpoints.

Gemini Notebook Enterprise documentation (comparison table): with the personal Gemini Notebook, users cannot specify data residency ('Users can't specify'). Google LLC is certified under the EU-U.S. Data Privacy Framework (Google Privacy Policy, Data transfer frameworks). Google Privacy Policy (Data transfer frameworks): 'We maintain servers around the world and your information may be processed on servers located outside of the country where you live.' A storage location specific to Gemini Notebook is not documented.

As Standard: data residency cannot be selected for personal accounts (Enterprise documentation); Google LLC certified under the EU-U.S. Data Privacy Framework. Google Privacy Policy (Data transfer frameworks): 'We maintain servers around the world and your information may be processed on servers located outside of the country where you live.' A storage location specific to Gemini Notebook is not documented.

not publicly documented: Workspace Privacy Hub: 'Your organization's file sharing and data region settings do not apply to data in Gemini Notebook.' Workspace Admin Help 'Data covered by data regions': Data Regions are not supported for Gemini Notebook. The pages do not name a storage location. Sources added from Drive are stored as a copy with the Gemini Notebook data.

Enterprise documentation: data stays in the customer's Google Cloud project; Gemini Notebook Enterprise is available in the 'eu' and 'us' multi-regions and 'global', with data residency commitments for storage (at rest) and ML processing depending on the location; for data in the EU, licences from an 'eu' subscription are required. Google recommends 'global' if there are no regulatory reasons for a region.
