Benefits of a temporary number for OpenAI / ChatGPT

Activation or rental
A one-time activation keeps the number for about 20 minutes, which is enough for one OpenAI / ChatGPT code. If you expect OpenAI / ChatGPT to ask for verification again, for example when you log in on a new device, a rented number is safer because it stays assigned to you for days or months. Read more in renting vs one-time numbers.
If the OpenAI / ChatGPT code does not come
Wait 1 to 2 minutes before requesting again, check that the country code is not entered twice, and try another number or country if OpenAI / ChatGPT refuses the first one. See 10 fixes for codes that do not arrive.
Use it responsibly
Temporary numbers are a privacy and testing tool. Follow OpenAI / ChatGPT’s terms of service, do not use numbers for spam, fraud or impersonation, and keep your own SIM on accounts you must be able to recover long term.
