🤖 Receive ChatGPT (OpenAI) SMS Online — Free
OpenAI asks for phone verification when creating some ChatGPT and API accounts to prevent abuse. If you'd rather not attach your personal mobile to another tech account, a free temporary number from SMSToMe can receive the OpenAI verification SMS — though note that OpenAI filters virtual numbers more aggressively than most services, so success may take a few attempts.

Frequently Asked Questions — ChatGPT (OpenAI) Verification
Why does OpenAI say "this phone number cannot be used"?
OpenAI actively blocks known virtual and VoIP number ranges. Try the newest number on SMSToMe, or a different country — and check the Telegram channel for freshly added numbers, which have the best success rate.
How many accounts can one number verify?
OpenAI limits how many accounts a single number can verify. If a shared number was already used, you'll see an error — simply pick a different number.
Does ChatGPT still require a phone number in 2026?
Not always — many sign-ups now complete with email only. Phone verification appears mainly for API/platform accounts and when abuse-prevention triggers. If you're not asked, you don't need a number at all.
Can I use the same number for account recovery later?
Shared numbers rotate, so don't rely on one for recovery. Keep a secure email on the account as your recovery method.
