## When do you need it?

OpenAI may ask you to verify a phone number when you **sign up, or sign in from a new device or network**. Many local numbers never get the text, and virtual numbers are usually refused. This is a **US number on a physical SIM**, not a virtual one, valid for **21 days**, and every text it gets shows on your order page.

## How it works

1. **Pay** — Card, Alipay or USDT. No sign-up, just an email.
2. **Get the number** — A US +1 number is assigned in seconds, on your order page and by email.
3. **Read the code** — Choose United States +1 when you sign in, enter the number, and the code shows on your order page.

## FAQ

### How long does the number last?

21 days. Every text in that time shows on your order page, so it also works when a later sign-in asks again.

### How many accounts can one number verify?

One OpenAI account. Verifying several accounts with one number tends to get them flagged.

### What if the code never arrives?

Switch network or VPN node and tap resend. If it still doesn't come, swap the number on your order page, up to 2 times per order at no charge.

### When can I get a refund?

If no number can be assigned, or none of your numbers received a text, the order page offers a refund to your original payment method. Orders that received a code are not refunded.

### Does it work for ChatGPT too?

Yes. Codex and ChatGPT share the same OpenAI account.

### Do you need my password?

No. You enter the number on your own sign-in page; we never see your account.
