Hi,
I am not OpenAI staff member. But let’s see if I can help you in any way.

From March 2023 until now, OpenAI has undergone intense changes, mainly with regard to security, including the hiring of Cloudflare for this area.

There are several symptoms when signing up for a new account:

  1. Your account has been flagged for possible abuse: Happens most often in
    1.1 Unsupported Countries - unresolved.
    1.2 Supported Countries - related to email reliability, browser reliability, and IP address already used - solution found.
    More details and solutions at: Your account was flagged for potential abuse ;

  2. Looks like this is a virtual phone number (also known as VoIP): So far it has only been detected in Canada (Supported Country). No solution so far.
    More details at: My phone number is not a VOIP! ;

  3. The carrier associated with this phone is not supported: so far only detected in Supported countries (non-US) - this thread;

The mobile/cell phone is only used to send SMS with the confirmation code for opening a new OpenAI account. It is normally not flagged - and may continue to be used when opening a new account, because

  • IP is temporarily flagged - must be changed;
  • The email is flagged… forever - another one should preferably be created on Google (@gmail.com.xx) and Microsoft (@outlook.com.xx, @hotmail.com.xx) domains. These two domains have a security/id verification service (one password for everything), and new users must sign in using the Google/Microsoft account.

Here in the forum, there are some who are suspecting that 2. VOIP and 3. Unsupported carriers are just justifications - and may be more related to some phone brands and software from Unsupported Countries.

What we can do is spot the coincidences as everyone in this thread seems to be from Supported Countries with different legitimate carriers.
Then describe what is possible for sign up:

  1. DO NOT PUT YOUR PHONE NUMBER HERE;
  2. Phone brand (Apple iPhone, Huawei, Samsung, etc.):
  3. Your active carrier service (3G, 4G, 5G, LTE, VoLTE, etc.):
  4. Any active messaging service/product (iMessage, FaceTime, etc.):
  5. Any software from Unsupported Countries on phone or computer (ad blocker, antivirus, Tik-Tok, etc.):
  6. Computer browser (Chrome, Edge, etc.):
  7. Any VPN service or hidden VPN under antivirus:
  8. Email domain (@abcde.xx):
    DO NOT PUT YOUR FULL EMAIL HERE

And we can check what coincides as the cause of some of these problems.
