Live experiment

I gave 11 companies 11 different phone numbers. Let's see who leaks them.

Most people give the same phone number to everyone. CloakID lets you give a different one to each relationship — so when spam starts, you know where it came from.

How it works

The experiment, in three steps.

1

Each company gets a unique number

Using CloakID, I created 11 different phone numbers — one per company. Each company only ever sees its own number.

2

Calls are tracked automatically

Every incoming call is logged. If a robocall, spam caller, or telemarketer shows up, we know exactly which number they dialed.

3

Spam reveals the leak

Because every company got a different number, spam traffic tells us exactly where the exposure came from.

The roster

The 11 companies.

Each got a unique CloakID number. If spam appears on that number, we know exactly which company leaked it.

Why this matters.

Your phone number was never meant to become your identity. But today it's used to identify you, track you, authenticate you, market to you, and sell your data. And once it spreads, you can't take it back.

CloakID changes the model. Instead of one number for everything, you get one identity per relationship. When something goes wrong, you can block it, retire it, or delete it — without affecting the rest of your life.

What CloakID does.

Think of it as a firewall for your identity.

  • Create separate phone identities for separate relationships
  • Screen unknown callers before your phone rings
  • Block, rotate, or retire exposed numbers in seconds
  • Keep trusted people on an approved list so they always get through
  • Know exactly where your number leaked — and who leaked it

This experiment is directional and observational. Spam on a number may result from sharing, resale, reuse, or other downstream exposure, and is not by itself proof of wrongdoing by any specific company.

Follow the results.

We publish updates as the experiment unfolds. If a company leaks, you'll see it here first.
