Digital Footprint Check: How Exposed Is Your Phone Number?
The Reality Check: Most people don't realize that their mobile number, address, and full name are often legally available to purchase online for less than the price of a coffee.
We often wonder, "How did these scammers get my number?" The answer is rarely a sophisticated hack. More often, we gave it to them—or rather, we gave it to a company that sold it, or we left it visible on a public profile. This guide helps you find where your number is leaking and how to plug the holes.
Step 1: The "Google Yourself" Test
It sounds simple, but have you ever searched for your own number?
- Open Google.
- Type your phone number in quotation marks (e.g.,
"07700 900123"). - Try different formats (with/without spaces, +44).
What to look for: Old CVs hosted on job sites, community club newsletters (PDFs), or classified ads you placed years ago. Contact the site owners immediately to request removal.
Step 2: The Social Media Audit
Social platforms are goldmines for data scrapers.
Go to Settings > Privacy > How people can find and contact you.
Set "Who can look you up using the phone number you provided?" to Friends or Only Me. If it's set to "Everyone," your number is searchable.
Check your "Contact Info" section on your profile. Many professionals list their personal mobile number here. Remove it and use a work email instead.
Step 3: The "Open Electoral Roll" & Data Brokers
This is the biggest source of legal data trading in the UK.
When you register to vote, you can opt out of the "Open Register" (also called the Edited Register). If you don't opt out, your name and address can be bought by anyone—marketing firms, debt collectors, or nosey neighbours—via sites like 192.com.
How to Fix It:
- Future: Always tick the "Opt out of the Open Register" box when you update your voter registration.
- Current: Visit sites like 192.com, search for yourself, and use their specific "CO1" form to request record removal. It is free, but they make it hard to find.
Step 4: The "Third Party" Trap
You sign up for a car insurance comparison site. You tick the box saying "I agree to the Terms & Conditions."
Buried in those terms is often a clause saying: "We may share your data with our trusted partners." "Trusted partners" can mean hundreds of marketing companies.
The Fix: Always look for the marketing preferences boxes. Often they use "Trick questions" (e.g., "Untick this box if you do NOT want to receive offers"). Read carefully!
