Hiding your phone number when calling is the ability to conceal your personal identity during a phone call. It’s done by using a variety of techniques like *67 or anonymous caller ID apps. For example, if you call a customer service line, you can hide your number to protect your privacy.
The ability to hide your number has become increasingly important in a world where phone numbers are often used for spam calls, phishing scams, and identity theft. By hiding your number, you can protect yourself from unwanted solicitations and potential harm.
