Enter the +381 number
Select Serbia (+381) in the country picker and paste the number from your dashboard without a leading 0. Serbia mobiles look like 06x xxx xxxx → +381 6x xxx xxxx (some numbers are one digit shorter).

Finish the profile; the number may be used again for API or security checks.
Day-to-day life in Serbia runs on Viber, WhatsApp and Instagram, yet ChatGPT (OpenAI) remains the app for an OpenAI account registered in a supported country. A +381 number keeps that account tied to the country without using your personal SIM.
Serbian diaspora: Large Serbian communities in Germany, Austria and Switzerland rely on Viber to reach relatives, and a +381 number keeps them part of those chats.
OpenAI can ask for the phone again for API access, billing or security reviews.
Viber is practically the national messenger in Serbia, used by families, shops and businesses alike. Belgrade has grown into a regional tech and freelancing hub, and many foreigners have relocated there in recent years. A +381 number helps newcomers, freelancers and the diaspora stay connected to Serbian life.
