Most obviously, it helps protect your personal privacy. For example, you may want to sign up for a new service without sharing your real phone number. With United SMS, you can receive SMS verification codes on a one-time number instead of exposing your personal contact information.

They must NOT be used for illegal activities, restoring access to other people's accounts, identity theft, financial fraud, or any other form of abuse. Please take a moment to read our article about prohibited uses for temporary phone numbers before requesting numbers for SMS verification through our service.

It may be possible to receive additional SMS verification codes from the same app or service by reusing a one-time number. We offer a 50% discount on MDN reuse requests. However, due to the nature of temporary phone numbers, we cannot guarantee that a one-time number will remain available for reuse. For more information, please read our article about reusing one-time phone numbers.

While our numbers are a paid verification service, we're currently offering a limited selection completely free for you to receive SMS online.
