OpenAI has re-enabled ChatGPT on WhatsApp across the European Economic Area, but only after a European Commission intervention forced Meta to reverse its ban on rival chatbots. Since July 13, 2026, users in the 27 EU member states plus Liechtenstein, Iceland, and Norway have been able to reach the chatbot by messaging the verified contact 1-800-CHATGPT (+1-800-242-8478). No OpenAI account is required to start a conversation, and the bot responds to text prompts, image uploads, voice messages, and image generation in multiple languages.
What the EU Ruling Changed for WhatsApp Chatbots
Meta removed ChatGPT, Microsoft Copilot, and Perplexity from WhatsApp on January 15, 2026, after updating its business rules to allow only Meta’s own AI assistant on the platform. The move drew immediate regulatory scrutiny. In June 2026, the European Commission issued interim measures under EU competition rules, ordering Meta to let third-party chatbot providers back onto WhatsApp free of charge. OpenAI’s ChatGPT was the first to reappear, and the company is expected to restore other services gradually. The ruling underscores how the EU’s digital markets framework can directly shape how major platforms handle AI integrations.
How ChatGPT on WhatsApp Works Now
When asked which model powers it, the chatbot states it runs on GPT-5.5. For image requests, the bot appears to route those queries to gpt-image-2, OpenAI’s dedicated image-generation model. Users can also link their WhatsApp account to a ChatGPT account, enabling the chat to pull in context from previous conversations and sync message history across devices. Voice messages are supported, and the system can handle multiple languages without switching. The experience is notably leaner than the full ChatGPT web or mobile app, but it provides a functional conversational AI layer inside the world’s most popular messaging platform.
Usage Limits and Model Routing Questions
OpenAI has not published explicit usage limits for unlinked WhatsApp users. Without an account, the bot may cap the number of messages or throttle response quality after a certain threshold. There is also uncertainty about whether OpenAI is quietly routing requests to older, less expensive models for anonymous users. The image generation quality observed in tests suggests gpt-image-2 is active, but the company could dynamically downgrade the model behind the scenes to manage costs. Users who link their accounts likely get higher priority and consistent model access.
Expansion Beyond WhatsApp
ChatGPT is also launching on the KakaoTalk messenger in South Korea and on Viber in other markets. These moves signal OpenAI’s strategy to embed its assistant into the messaging apps where billions of users already spend their time, rather than requiring them to open a separate ChatGPT interface. Each integration adapts to the platform’s native features — WhatsApp supports end-to-end encryption, so OpenAI must work within those constraints.
What European Users Should Do Now
Anyone in the EEA with WhatsApp installed can message +1-800-242-8478 and start interacting with ChatGPT immediately. No sign-up is required, but linking a ChatGPT account unlocks context syncing and likely more favorable usage limits. Users should be aware that the bot is still a research preview-level service within WhatsApp, and OpenAI may fine-tune the experience based on traffic and regulatory feedback. This development also serves as a reminder that regulatory actions can directly expand user access to competing AI tools on dominant platforms — a trend worth watching as other jurisdictions consider similar rules.
