Why a second number
You give it to the marketplace buyer, the dating match, the delivery guy, the form that “requires” it. Then come the spam calls, the awkward messages, the number you can't take back — because your real number is forever.
SpareNumber gives you a second number for all of that. Hand it out freely. Keep your real one for the people who've earned it.
Features
Crystal-clear calling over Wi-Fi or data — powered by real carrier-grade infrastructure, not a walkie-talkie app.
The person on the other end sees your SpareNumber — never the number your mom calls.

Send and receive SMS like you always do. Same thumbs, different number.
Missed a call? Your second line takes a message like a proper phone should.
Block numbers, silence spam, and keep your second line as calm as your first.
Pick a number that fits — your city, your country, or somewhere you do business.
How it works
Pre-register on Google Play and it installs automatically the day we launch. Coming to the App Store too.
Choose a local or international number you like. It's yours.
Start talking. Your real number stays out of it.

Use cases
Post the listing, take the calls, close the deal. When it's sold, the buyer has a number that isn't you.
Chemistry is great. Giving a stranger your permanent number on date one is not. Text freely, decide later.
A dedicated 2nd line for work that rings on your own phone. Look professional without carrying two devices.
A local number without hunting for a SIM kiosk at the airport. Wi-Fi is all it needs.
Privacy & security
Your calls route through our infrastructure but are never recorded — and messages aren't stored once delivered.
Calls and texts travel over encrypted protocols wherever technically supported.
Your personal data is not for sale. Not to advertisers, not to data brokers, not to anyone.
We collect the minimum needed to run the service — and our Privacy Policy says exactly what that is, in plain English.
