Stop giving out your real phone number

Jan 20, 20264 min read

Think about all the places that have your phone number right now:

  • Every app you've ever signed up for
  • Every online order you've ever placed
  • That car dealership from 2019
  • Your gym, your dentist, your landlord
  • That one website where you just wanted to see the price

Your phone number is the one piece of personal information you can't change without enormous hassle. And you hand it out like Halloween candy.

Why your phone number is more sensitive than your email

You can create a new email in 30 seconds. You can't create a new phone number without updating every bank, every account, every contact. Your phone number is effectively permanent — which makes it the perfect tracking identifier.

Data brokers use your phone number to:

  • Link your identities across services
  • Build advertising profiles
  • Sell your data to robocallers
  • Enable SIM swap attacks

The two-number solution

The fix is simple: have two numbers.

Number 1 (your real number): For banks, government, close friends and family. Guard it like your SSN.

Number 2 (your cloud number): For everything else. Shopping, apps, forms, services, acquaintances, Craigslist, dating apps, work contacts.

If your cloud number gets compromised or starts getting spam, you can manage it without affecting your banking and personal contacts.

"Isn't that complicated?"

No. Your cloud number lives in your browser alongside your real phone. You don't carry two devices. You don't switch SIMs. You just have a second number that rings in a browser tab.

When a website asks for your phone number, you give them your Jaambo number. When your bank needs to verify your identity, you use your real number. Simple.

The bonus: it works everywhere

Since your cloud number isn't tied to a carrier or country, it works anywhere you have internet. Travel internationally without roaming charges. Move countries without losing your number. It's a phone number that's as flexible as your email.
