About OpenAI numbers in Slovakia
OpenAI (ChatGPT) requires one-time phone verification per account; one number can only verify a limited set of accounts, ever. VoIP ranges are rejected — the mobile numbers here pass that check. The SMS contains a 6-digit code and arrives near-instantly; the number is never needed again after signup.
Slovakia numbers are issued in the +421 mobile format and can receive SMS from 493 services. For OpenAI, this country currently ranks 161 of 180 available countries by price.
