Phone numbers are more than just digits — they are gateways to personal communication, sensitive information, and digital identities. Because of their importance, misusing phone numbers is taken seriously by governments and regulatory bodies worldwide. Misuse can include activities such as unauthorized access, spam, fraud, identity theft, and privacy violations. Various laws and regulations impose penalties ranging from fines to imprisonment to deter such misuse and protect individuals’ rights.
Common Types of Phone Number Misuse
Spam and Unsolicited Calls/SMS:
Sending unwanted marketing messages or robocalls without consent is a widespread problem. It disrupts users’ lives and wastes network resources.
SIM Swapping and Identity Theft:
Fraudsters hijack phone numbers by convincing mobile providers to transfer a victim’s number to a new SIM card. This allows them to intercept calls and messages, often used to bypass two-factor authentication (2FA).
Phishing and Social Engineering:
Using phone numbers to trick individuals into revealing recent mobile phone number data personal information or to impersonate trusted entities.
Harassment and Stalking:
Repeated calls or messages intended to intimidate or harass someone.
Unauthorized Data Collection and Sharing:
Collecting or selling phone numbers without user consent violates privacy laws.
