Phone Verification issue - This phone number is already linked to the maximum number of accounts

I’m having trouble verifying the phone number in the registration. The phone number I want to enter was linked to an existing account that I deleted, but the system won’t let me link that phone number again.

How can I solve it?

There is no clearing or reset of phone numbers even by OpenAI staff. “Delete account” makes the phone number forever unusable, even for the second account you could have created before.

You are just another datapoint in confirming it still is working that way.
