About OpenAI numbers in Singapore
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.
Singapore numbers are issued in the +65 mobile format and can receive SMS from 290 services. For OpenAI, this country currently ranks 180 of 182 available countries by price.
