Go to the phone step during sign-up or when creating API keys on the OpenAI platform.
Enter the +43 number
Select Austria (+43) in the country picker and paste the number from your dashboard without a leading 0. Austria mobiles look like 06xx xxxxxxx → +43 6xx xxxxxxx (length varies by operator).

Finish the profile; the number may be used again for API or security checks.
Day-to-day life in Austria runs on WhatsApp, Instagram and Facebook, yet ChatGPT (OpenAI) remains the app for an OpenAI account registered in a supported country. A +43 number keeps that account tied to the country without using your personal SIM.
Students in Vienna and Graz: International students at the University of Vienna, TU Wien or Graz use an Austrian number for flat hunting on willhaben and university services.
OpenAI can ask for the phone again for API access, billing or security reviews.
Austria’s mobile numbers have a variable length, a quirk that sets them apart from most of Europe. Vienna hosts UN agencies, OPEC and a large international student body, while the Alps draw millions of winter visitors each year. With prepaid SIMs requiring ID since 2019, many newcomers look for an Austrian number they can set up without visiting a shop.
Local context
Since 2019 Austria requires ID verification to activate any prepaid SIM, so short-term visitors can’t buy one anonymously. A Austria number from PhoneBorn needs no SIM and no ID — only an email.
