Phone verification is no longer required for creating a new OpenAI account or using ChatGPT. However, it is now required on platform.openai.com when generating your initial API key, but not for any subsequent API key generation.
If you're not receiving your phone verification code, here are a few possible reasons and steps to help resolve the issue:
Ensure you are using a mobile number that is supported. OpenAI does not support VoIP, landline numbers, or premium numbers
Double-check that you've entered the correct phone number and country code
Ensure you have a strong network connection. Sometimes, it may take a few minutes to receive the code, but depending on your mobile carrier or network conditions, it could take longer
Check if your phone is blocking unknown or spam messages. You may need to adjust your settings or contact your provider to allow verification codes
If you've attempted to verify your phone multiple times, the system might have temporarily blocked you. Try again in a few hours
If you've tried all these steps and still can't receive the verification code, please reach out to the support and provide your full phone number, including the country code, so further investigation can be conducted.
