Phone number formatting bug for +251 adds extra leading zero and prevents verification code delivery
What issue are you seeing?
When attempting to log in to Codex, I am redirected to the "Add Phone Number" page. After entering my phone number with the country code +251 (Ethiopia), the system incorrectly modifies the number during the verification step.
Specifically, I enter my number in the format:
+251 9XXXXXXXX
But on the verification screen, it is displayed as:
+25109XXXXXXXX
This results in an invalid phone number format, and I do not receive the verification code.
What steps can reproduce the bug?
Log in to Codex.
Get redirected to the "Add Phone Number" page.
Select or confirm country code +251.
Enter a valid Ethiopian mobile number starting with 9XXXXXXXX (without leading 0).
Submit the phone number.
Observe the number shown on the verification page.
What is the expected behavior?
The phone number should remain in the correct international format:
+251 9XXXXXXXX
It should not prepend an extra 0. The system should send the verification code to the correctly formatted number.
Additional information
This appears to be a formatting issue where a leading 0 is incorrectly added after the country code.
Ethiopian phone numbers should not include the leading 0 when using the international format (+251).
Because of this issue, users are unable to receive verification codes and cannot proceed with login.

Exactly Same Issue!
I think it's a UI formatting bug, and it doesn't have anything to do with not receiving verification code problem. If you check the response body after verification code request, the phone number is still in the correct format (which would be +2519XXXXXXXX in your case). But nvm, I couldn't receive the verification code either...

Please let me know if anyone has found a workaround—this is getting really frustrating.
After this, I’m no longer able to add a new number at all.

Formatting issue looks fixed now, but SMS verification is still failing.
UI error:
"Unable to send a verification code to this phone number. Please try again later or use a different number."
API response:
code: "fraud_guard"Response message:
"We've detected suspicious behavior from phone numbers similar to yours. Please try again later or contact us through our help center."
This is happening even though I’m using the phone number for the first time
@henokhackz It worked for me and I received the SMS successfully.
I’d suggest logging out of ChatGPT, logging back in, and then signing into Codex again that might fix it.

SMS option still doesn’t work, but they added a WhatsApp option, and I’m able to log in using it and receive the verification code.
