3. Potential for DoXXing and Harassment:
In more serious scenarios, if your publicly listed number is associated with other publicly available personal information, malicious individuals could potentially use it for doxxing – revealing your private information online – which could lead to harassment or even real-world safety risks.

4. Increased Vulnerability to Social Engineering Attacks:
Scammers may use your publicly listed number as a starting point for social engineering attempts. They might try to impersonate trusted entities or individuals to trick you into revealing sensitive information or performing certain actions on WhatsApp or other platforms.

While WhatsApp has settings to control who can add you to groups, publicly known numbers are more likely to be added to random or promotional groups, which can be annoying and expose your number to a wider audience.

Your publicly listed phone number can be easily collected and aggregated with other online data by various entities, including marketing companies or data brokers. This can contribute to the creation of detailed profiles about you, potentially impacting your privacy across different online services.

Mitigating Risks (Limited):

It's important to understand that WhatsApp requires a phone number to function, and there is no built-in way to completely hide your number within the app. However, you can take some steps to mitigate the risks associated with a publicly listed number:

Adjust Privacy Settings: Limit who can see your profile photo, "About" info, and "Last Seen" status to "Contacts" or "Nobody."
Be Cautious About Sharing: Avoid sharing your WhatsApp number publicly on websites, social media, or in other easily accessible online spaces.
Enable Two-Step Verification: This adds an extra layer of security to your account.
Use the "Block" Feature: Block unwanted contacts or numbers immediately.
Report Spam: Report spam messages and contacts to WhatsApp.
Consider a Secondary Number: If you frequently need to share a contact number publicly, consider using a secondary phone number specifically for that purpose, keeping your primary WhatsApp number private.
In conclusion, while using a publicly listed phone number for WhatsApp offers convenience in certain situations, it significantly increases your exposure to various privacy and security risks. Users should carefully weigh these risks against the benefits and take proactive steps to manage their privacy within the platform.
