Sharing your phone number may seem harmless, but experts warn that this information can open the door to financial and security risks. Being linked to multiple personal accounts, a simple action can lead to more complex frauds.
1. It can become the key to your identity
The telephone number is considered the deepest identifiable information. It is linked to bank accounts, emails and social networks, making it a starting point for criminals to collect more data through public records or information brokers.
With enough combined data, they can build a complete profile that facilitates financial fraud.
2. Fraud calls and messages increase
By sharing your number, you are more likely to receive fake calls or messages that appear to be from banks, delivery services, or government institutions.
This type of deception, known as ‘smishing’, seeks to get the person to click on malicious links or share sensitive data.
Older adults are usually one of the most vulnerable groups, with significant economic losses in this type of scams.
3. Risk of having alters taken from your accounts
One of the most dangerous frauds is ‘SIM swapping’, where criminals manage to transfer your number to another device.
By having an alter of your line, they can intercept verification codes and access important accounts like online bankingemail or even retirement funds.
4. They can use your identity to deceive others
If someone gains access to your number, they can impersonate you. This allows them to send messages to family or friends requesting money or deeper information.
By coming from a known number, these messages generate trust, which facilitates fraud and can affect personal relationships.
5. Loss of privacy and potential abuse
In addition to the financial risks, sharing the number can lead to harassment, constant messages, or even activity tracking on linked apps.
Once the number becomes public or circulates in different databases, it is very difficult to control who has it or eliminate it completely.
A risk that goes beyond digital
The telephone number has become a key piece in digital security. Its misuse can not only affect finances, but also people’s privacy and peace of mind.
