Free phone numbers for SMS verification
Free temporary phone numbers to receive SMS verification codes online
Get a free phone number for SMS verification without signing up. Use a temporary number to receive OTP codes for WhatsApp, Telegram, Google, and more — then upgrade to paid virtual numbers when you need privacy, higher success rates, or unlimited activations.
Public free numbers — success rates can be low
These free SMS numbers are shared publicly. Anyone can see and reuse them, so many platforms may block or throttle verification. Expect lower success rates than private paid numbers. For reliable OTP delivery, privacy, and access to hundreds of services, use paid SMSTwins numbers.
Daily free limit
You can get up to 15 free phone numbers per day. For unlimited SMS verification numbers, create a free account and buy paid virtual numbers.
Need privacy and high success rates?
Paid virtual numbers are private to your account, routed for higher OTP success, and work across many services and countries. Ideal when free public numbers fail, when you verify different apps often, or when you want a clean number that is not shared with the whole internet.

Can I get a free phone number for SMS verification?
Yes. SMSTwins offers free temporary phone numbers so you can receive SMS verification codes online without an account. You may claim up to 15 free numbers per day. For unlimited use, sign up and purchase paid virtual numbers.
Why do free SMS numbers often fail verification?
Free numbers are public. Many people reuse the same lines, so apps like WhatsApp, Telegram, or Google may reject them. Paid SMSTwins numbers are private to your session and usually deliver much higher success rates.
When should I use paid virtual numbers instead?
Choose paid numbers when you need privacy, higher OTP success, rentals, API access, or to verify many different services. Developers integrating signup testing should use the paid API rather than free public receivers.
Is there a daily limit on free temporary numbers?
Yes — up to 15 free phone numbers per day. For unlimited use, sign up and purchase paid virtual numbers.
