What version of the Codex App are you using (From “About Codex” dialog)?

26.609.41114

What subscription do you have?

Enterprise

What platform is your computer?

Darwin 27.0.0 arm64 arm

What issue are you seeing?

I can no longer log into my work Codex account because of phone number verification. Support is not responding.

It's requiring phone number verification, but I cannot use my personal cell phone number because I used it for my personal ChatGPT account already (which is plus tier btw), and now I cannot verify for my work account. I am required to use my employer's subscription to work on our codebase, so I need this fixed ASAP :)

What steps can reproduce the bug?

Click login with ChatGPT in codex after being logged out because session token expired or something
Login with your ChatGPT enterprise email (work email)
Need to verify phone number
This phone number is already linked to the maximum number of accounts.

What is the expected behavior?

Enterprise/work accounts should be exempted from the requirement, especially since they are paid for! I understand abuse prevention on free tier, but enterprise tier is typically most expensive.

Not duplicate, this is an enterprise ChatGPT account from employer not a personal account

Same problem. Can't log in. When the pop-up window appears, nothing happens when I click any buttons.

Adding my case as a data point — same symptom, and I've already exhausted the official support route.

Environment:

Codex app on Windows
Free ChatGPT account (no paid subscription)
ChatGPT web login works perfectly with the same account
Country: Japan, carrier: NTT docomo

Symptom:
Codex sign-in redirects to auth.openai.com/add-phone. Entering my mobile number instantly returns "verification limit reached" — no SMS is ever sent, so this is not a delivery issue but a server-side block on the number.

Cause (confirmed via OpenAI Support):
My number was used years ago to verify one old account of mine. That's it — one account. Support confirmed my current (primary) account has no phone number associated with it.

What OpenAI Support said (two specialists, multiple exchanges):

Unlinking/changing a phone number: not possible
Manually resetting the verification limit: not possible
One-time exception / manual verification: not possible
Deleting the old account to free the number: does not free it
Support "doesn't have visibility into the number of accounts associated with a specific phone number or the ability to modify its verification status"
Their only suggested option: use a different phone number

Note the contradiction: support also stated a number can verify "up to three different accounts" — mine has been used on exactly ONE, yet it's instantly blocked. This suggests the limit logic itself may be buggy, or the error message is wrong.

A user fully authenticated on the web is blocked at the Codex entry by a phone-number limit that support can neither inspect nor reset, with no replacement or recovery path. Please provide a supported path to replace/reset a phone number, or fix the limit counting if it is miscounting.

My team already moved to Claude Code because of this issue, I recommend others facing issues to do the same since I have not encountered anything like that on Anthropic's end yet...
