How to Safely Handle Private Number Calls: A Guide for Everyday Users

Receiving calls from private or unknown numbers can be unsettling. While some may be legitimate, others could be unwanted solicitations or potential scams. Understanding how to handle these calls can help you make informed decisions.

What Are Private Number Calls?

A "private number" call occurs when the caller intentionally hides their phone number from your caller ID. This is often achieved by dialing a specific code before the number (e.g., *67 in the U.S.) or by configuring the phone settings to block the number. While this feature can be used for privacy reasons, it is also commonly exploited by telemarketers and scammers. (nice.com)

Should You Answer Private Number Calls?

It's generally advisable to exercise caution with private number calls. Many legitimate callers, such as doctors or businesses, may use private numbers to protect their privacy. However, the anonymity provided by private numbers is also favored by telemarketers and scammers. Therefore, answering such calls without screening can expose you to unwanted solicitations or potential fraud. (icaughtyou.com)

How to Identify and Unmask Private Number Calls

If you receive a call from a private number and wish to identify the caller, consider the following methods:

  1. Use Call Return Services: In the U.S., dialing *69 immediately after receiving a private call can help you identify the last incoming call. This service may not work if the caller has blocked their number using certain methods. (avg.com)

  2. Contact Your Service Provider: Some carriers offer services to unmask private numbers. For instance, T-Mobile's Scam Shield and AT&T's Call Protect can sometimes reveal blocked numbers. (reversephonelookup.org)

  3. Use Third-Party Apps: Applications like Truecaller and TrapCall can identify unknown callers by accessing a vast database of phone numbers. These apps can provide information about the caller, including their name and location. (makeuseof.com)

How to Block Unwanted Private Number Calls

If you prefer not to receive calls from private numbers, you can block them using the following methods:

  • On iPhone: Go to Settings > Phone > Silence Unknown Callers. This feature silences calls from unknown numbers and sends them to voicemail.

  • On Android: Open the Phone app, tap the three-dot menu, select Settings > Blocked numbers, and enable "Block unknown callers."

  • Using Call Blocking Services: Some carriers and third-party apps offer services to block calls from private numbers. For example, Verizon's Call Filter and AT&T's Call Protect can block or identify spam and robocalls. (aura.com)

When to Seek Help

If you receive repeated private number calls that are harassing or threatening, consider the following steps:

  1. Document the Calls: Keep a record of the dates, times, and frequency of the calls.

  2. Contact Your Service Provider: Inform them of the situation; they may offer additional services or advice.

  3. Report to Authorities: If the calls are threatening or constitute harassment, report them to local law enforcement.

Conclusion

While private number calls can sometimes be legitimate, they are often used by telemarketers and scammers. By understanding how to identify and manage these calls, you can protect yourself from unwanted solicitations and potential fraud. Utilizing available tools and services can help you make informed decisions about answering or blocking private number calls.
