What OpenAI requires from a number
- Non-VoIP required
- Yes. VoIP ranges are rejected or limited.
- Number reuse
- A number can verify more than one account over time.
OpenAI rejects VoIP and virtual desk numbers at signup, so the number has to be a real carrier line. Verification is tied to the number itself: a line already attached to an OpenAI account may be refused on a new signup. On a one-time OTP, reusing the same number is free inside the 15-minute window and paid after it expires; a rental or dedicated line keeps the same number for as long as you hold it.
AI agents
An agent can handle OpenAI verification
An AI agent can rent the OpenAI number, poll for the incoming message and read the parsed code through VoidMob's open-source MCP server, with no dashboard round trip. Works with Claude, Cursor and any MCP client.
Verifying OpenAI with a real carrier number
OpenAI no longer asks for a phone number to create a ChatGPT account, but it still requires one on platform.openai.com before it issues your first API key, and it can ask again on later verification or account-change steps. The check runs against carrier data, not just number format: OpenAI states it does not support landlines, VoIP, Google Voice or premium numbers, so those are refused before a code is ever sent. What passes is a real mobile line on a carrier network, which is what the numbers in this catalog are: non-VoIP carrier numbers that receive the OTP the same way a handset would.
Three ways to take the code. A one-time OTP holds a US number for 15 minutes and starts at $0.25 for OpenAI/ChatGPT; if no code arrives in the window the rental cancels and refunds in full, and reusing the same number inside the window costs nothing. A multi-day rental keeps a US number for 3, 7, 14 or 30 days, always active, which covers re-verification, API tier changes and login challenges that land days after signup. A dedicated monthly non-VoIP line is the option offered per country, currently from $16.99 a month, and it stays yours across platforms.
Pick by how long you need to be reachable. If the account is throwaway-adjacent or you only need the initial signup code, a one-time OTP is enough. If the account holds a billing relationship, an API key or a team workspace, treat the number as part of that account's identity and hold it: losing the line means losing the recovery path. Pair either with a stable IP if you sign in from unusual locations, because OpenAI weighs login network and device signals alongside the number.
