Telephones, especially cell phones, are an integral part of our modern-day lives, and many of us use our phones throughout the day to call and text others. However, it’s important to understand phone call safety, as ensuring that you only call safe phone numbers can help you protect your privacy and personal information.

Why Should You Be Careful When Calling Certain Phone Numbers?

Calling certain phone numbers can be dangerous, as they might accidentally connect you to scammers and spam callers.

You can utilize services to hide your phone number from the receiver if you are worried about your identity being revealed when you call certain numbers.

If you cannot find any information, there’s a good chance that the number is a bad idea to call.

Common Scam Area Codes

Along with the above numbers, there are some area codes (this is the location indicator at the front of a phone number) that are well-known to be associated with scams or spam. They also have a +1 country code, which can lead some people to trust these numbers, even if they aren’t familiar with the number.

You should be wary of phone numbers with the following scam area codes:

216 – Cleveland, Ohio
218 – Northern Minnesota
332, 347, 646 – New York City, New York
657 – La Palma, California
712 – Western Iowa
268 – Antigua and Barbuda
649 – Turks and Caicos
829 – Dominican Republic
868 – Trinidad and Tobago
876 – Jamaica

It’s especially important to pay attention to these area codes and to any country codes attached to a number calling you. Repeated calls from areas and countries that are far away from your location can indicate that your number is being targeted by scammers or spam callers.

How Can I Detect a Dangerous Number?

Figuring out if something is a dangerous number can be relatively easy once you know which red flags to look for. We give you several red flags to look out for to help you determine if a number is safe to call or not:

You do not recognize the number, or the number has a suspicious area code
The number does not leave a message, but it repeatedly calls your phone
Your phone flags a text or call as a potential scam
The number leaves a message, but the message is a classic scam starter, such as claiming you’ve won money or you have a package for delivery
You accidentally answer the call, and the person on the other end tries to threaten you, coerce you into handing over money, or sweet-talk you by offering something too good to be true.e

You should keep in mind that, generally, if a number is raising one or two red flags, it is probably not a phone number you should call back. If the number calls you again and they happen to leave a valid message, or if you connect the number to a person you actually know, it might be safe to dial the number.

However, only do this if you are certain you are not calling back a scammer or an unsafe number.

Should I Answer Suspicious Numbers?

If you receive a call from an unknown or blocked number, or if you receive text messages from suspicious numbers, you should refrain from answering them. While these calls and texts may be from robodialers and relatively harmless, save for being a nuisance, others could be targeted calls by scammers and spammers.

Never return a call to a number that has been marked as spam or a scam by your phone, and do not reply to scam text messages. Doing so could lead to the scammer getting more of your information, confirming that your number is active, and further harassing you. Make sure to use your cell phone’s settings to block and screen suspicious calls as necessary.

Understanding Phone Call Safety

Our cell phones are an important part of our lives today, and it’s vital that you understand phone call safety when using your phone. Scams and spam phone numbers are something that can be a nuisance or a serious safety risk, and you do not want to risk accidentally dialing a phone number that leads to your information or money being stolen.
