OpenAI requires a verified phone number during the account creation process for ChatGPT, the OpenAI API, DALL·E, and all associated products. If you do not want to link your personal number — or if you need to create multiple OpenAI accounts for testing, research, or development — a temporary virtual phone number is the cleanest solution.
NumberOTP supplies real, carrier-grade numbers from 70+ countries. Unlike generic VoIP numbers, our numbers are sourced from actual SIM pools, which means they consistently pass OpenAI's carrier validation and deliver OTP codes without being flagged or blocked.
Instant OTP Delivery
OpenAI SMS codes typically arrive within 5–15 seconds. Our dashboard displays the code the moment it lands — no polling or refreshing required.
No Personal Info Exposed
Keep your personal phone number private. The temporary number receives the OTP and is discarded afterward — your real number is never shared with OpenAI.
