Go to the phone step during sign-up or when creating API keys on the OpenAI platform.
Enter the +41 number
Select Switzerland (+41) in the country picker and paste the number from your dashboard without a leading 0. Switzerland mobiles look like 07x xxx xx xx → +41 7x xxx xx xx.

Day-to-day life in Switzerland runs on WhatsApp, Instagram and Twint, yet ChatGPT (OpenAI) remains the app for an OpenAI account registered in a supported country. A +41 number keeps that account tied to the country without using your personal SIM.
Ski and travel bookings: Visitors to Zermatt, Verbier or St. Moritz use a Swiss number for hotels, ski schools and mountain guides.
OpenAI can ask for the phone again for API access, billing or security reviews.
Switzerland has four national languages and one of Europe’s largest shares of foreign residents, drawn by finance, pharma and international organisations in Geneva. Payments run on Twint, which is tied to a Swiss mobile number. Because the country sits outside EU roaming rules, many commuters and visitors prefer to hold a +41 number.
Local context
Switzerland is outside the EU, so EU roam-like-at-home doesn’t apply, and buying a local SIM requires showing ID. A Switzerland number from PhoneBorn needs no SIM and no ID — only an email.
