Why non-VoIP numbers matter

Higher acceptance rate: Google, OpenAI and banks detect VoIP ranges and reject them; carrier numbers pass far more often.
Built for second-factor verification: keep the number for 11-30 days and renew it instead of losing access after one code.
Private by design: each account only sees its own numbers, codes and links — nothing is shared publicly.
Built for scale: bulk purchase, batch txt export and an API for automation or downstream services.

How it works

Register and top up with Alipay / WeChat (or redeem a code).
Pick a project, prefix and day tier in the market, then place the order.
Enter the number on the target platform; the code shows up in your SMS center within a minute.
Need it longer? Renew before expiry — each renewal adds 30 days.

FAQ

What is a non-VoIP number?

A non-VoIP number is a real carrier number (for example US T-Mobile) instead of an internet-based virtual line. Platforms like Google, OpenAI and banks are much more likely to accept it.

How long can I keep a number?

sms688 sells by days: 2-10, 11-20 and 21-30 day tiers. You can renew before expiry, each renewal adds 30 days.

How fast do codes arrive?

SMS usually arrives within a minute and shows up automatically in your SMS center; the public link for each number always shows the latest message.

Can I use the API?

Yes. Every account can generate an API key to check stock, buy numbers and fetch codes programmatically — see the API docs after signing in.
