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. InstantNum gives you a shared inbox instead â you read the SMS on the web, copy the code, and move on.
What We Offer
Public Numbers
Access to temporary phone numbers from over 8 countries worldwide. Perfect for quick verifications, testing applications, and one-time account setups. All messages are visible publicly for transparency.
Instant SMS Reception
Messages arrive in real-time without any delays. No registration or sign-up required. Simply select a number, use it for verification, and check the inbox instantly. It's that simple.
Privacy Protection
Keep your personal phone number private. Use our temporary numbers instead of your real number when signing up for services, testing apps, or verifying accounts you don't fully trust.

Never Use For:
- Banking, financial services, or payment apps

- Two-factor authentication for important accounts
- Any service containing personal or sensitive data
- Long-term account access

- Temporary access to non-sensitive services
- SMS functionality testing
- App development and QA testing
Remember: All messages received on public numbers can be viewed by anyone. Never use them for sensitive or important accounts.
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 filter some message types (banking, 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 guides page covers what to do when SMS does not show up.
