Every day, millions of people enter their personal phone numbers when registering on various websites and applications. It may seem harmless—just another verification step. But in reality, it can lead to serious consequences.
Why is this a problem?
Your phone number is not just a sequence of digits. It is a unique identifier linked to your identity, bank accounts, social networks, and many other services.
Main risks:
1. Data leaks
Every time you enter your number on a website, you trust its owners. But companies are regularly hacked:
In 2023, more than 2,800 major data breaches occurred
Over 8 billion personal data records were compromised
Phone numbers are often included in stolen databases
2. Spam and fraud
Once your number gets into databases:
You start receiving spam calls
Scammers use it for phishing attacks
The number may be sold on the black market
3. Identity tracking
A phone number allows:
Linking all your accounts together
Tracking your online activity
Building your digital profile
4. SIM swapping
Attackers can:
Convince a carrier to transfer your number to a new SIM card
Gain access to all accounts linked to the number
Bypass two-factor authentication
Real-life consequences
Case 1: Crypto wallet hack
An investor lost $24 million in cryptocurrency after attackers accessed his phone number via SIM swapping and bypassed two-factor authentication.
Case 2: Identity theft
After a data breach at a popular online store, a user became a victim of credit fraud—loans were taken out in their name.
Case 3: Stalking
A former partner used a phone number to track the victim’s location and activity through services where the number was registered.
