Open ChatGPT (OpenAI)
Go to the phone step during sign-up or when creating API keys on the OpenAI platform.
Enter the +352 number
Select Luxembourg (+352) in ChatGPT (OpenAI)'s country picker, then paste the digits your dashboard shows after +352 into ChatGPT (OpenAI).
Enter the ChatGPT (OpenAI) code
ChatGPT (OpenAI) sends a 6-digit code by SMS. SMS codes appear in your PhoneBorn dashboard next to the +352 number; type the code into ChatGPT (OpenAI) to finish.
Tips for Luxembourg numbers
- After +352, Luxembourg mobile numbers begin with 6 — a quick check that you pasted the whole number.
- Only need one code and the country doesn't matter? Ukraine costs $0.25 for ChatGPT (OpenAI), against $1.64 here.
- Keep your email and number consistent between ChatGPT and the API platform.
Why use a Luxembourg number for ChatGPT (OpenAI)?
Day-to-day life in Luxembourg runs on WhatsApp, Instagram and Facebook, yet ChatGPT (OpenAI) remains the app for an OpenAI account registered in a supported country. A +352 number keeps that account tied to the country without using your personal SIM.
Cross-border workers: Roughly 200,000 people commute daily from France, Belgium and Germany, and a Luxembourg number lets them keep work contacts separate from their home-country line.
OpenAI can ask for the phone again for API access, billing or security reviews.
