How far has your number travelled?

Six honest questions. One rough — and usually uncomfortable — estimate of how many databases hold your mobile number right now.

Answer honestly

Your last few years, in six questions.

1 · How many food delivery & shopping apps have your number?

2 · Loyalty programmes you’ve ever joined — restaurants, stores, pharmacies, fuel?

3 · Events, exhibitions or weddings where you filled a form or scanned a pass?

4 · Gyms, clubs, societies, schools or associations with your number on record?

5 · Website and app sign-ups where the form demanded a mobile number?

6 · How many years have you had this number?

A rough, conservative estimate:

0+ databases likely hold your number.

And that’s before any of them shared it onward — to marketing agencies, SMS vendors and “partners”. Every copy is permanent. None of them ever asked again.

The fix isn’t changing your number. It’s never giving it out again.

This is an illustrative estimate based on your answers, not a measurement. The real number is unknowable — which is rather the point.

Why this matters

Every copy is a door.

Spam is the least of it

Distributed numbers fuel profiling, social engineering and identity mapping — attacks that start with “we know your number and your name”.

No copy ever comes back

There is no recall button on a shared database. Deletion requests chase copies that have already multiplied.

The only winning move

Stop handing out the permanent identifier. Hand out a permission-based one instead — and keep the power to revoke it.
