About ReceiveTmpSMS
ReceiveTmpSMS is a free public inbox viewer for temporary phone numbers. We list numbers from supported countries so you can receive SMS verification codes in the browser without creating an account.
Public inboxes
Messages are visible to everyone. Do not use these numbers for banking, email recovery, or sensitive accounts. Read the disclaimer.
Why we built this
A lot of sites want a phone number before you can even look around. Handing over your personal SIM for every trial, test account, or throwaway signup gets old fast. ReceiveTmpSMS gives you a shared inbox instead - you read the SMS on the web, copy the code, and move on.
We only offer shared public numbers. There is no private rental, no paid exclusivity, and no outbound calling. The product stays simple on purpose: pick a country, open a number, read the inbox.
What we offer
Public numbers
Shared temporary numbers you can open in the browser. Fine for quick OTPs, app testing, and one-time signups - never for private accounts.
Instant inbox view
Pick a number, request the SMS elsewhere, then refresh the inbox. No account and no payment for public inboxes.
Keeps your SIM out of it
Useful when you want a code but do not want to hand your personal number to every untrusted form.

A few honest notes
Public numbers are not a privacy product in the strong sense. Anyone can open the same inbox you are looking at. They are convenient, not confidential.
We may filter some message types (for example banking or password resets) on purpose. If you need a code for something important, use your own number.
Availability changes. A number that worked yesterday might be overloaded today. The FAQs cover what to try when SMS does not show up.
