Why Do I Receive Call from an Unknown Number? How to Avoid

Receiving a call from an unknown number has (almost) become a norm these days and it sure can be annoying. 

According to the FTC, scammers are more likely to contact you by phone than any other method. Victims of scam calls lose an average of $1,200, which is significantly higher than losses from texts, emails, or websites. 

The thing is, sometimes it’s a spam call, and other times it might be important. Knowing who’s behind that mysterious number can save you from stress and keep you connected to the right people. 

In this blog post, we’ll explain why you might get calls from unknown numbers and give you tips on how to avoid them.

Key Takeaways

  • “Unknown Caller” indicates your phone provider can’t identify the caller, while “No Caller ID” means the caller has intentionally hidden their number.
  • Calls from unknown numbers can be from scammers or telemarketers.
  • You can block “No Caller ID” calls on iOS and Android devices to avoid interruptions and potential scams.
  • Use *69 and *57, or TrapCall and TrueCaller, to identify unknown callers and avoid scams.
  • TurisVPN can help you protect your data, especially on public WiFi, ensuring your online activity remains private and secure from hackers.

What Is “Unknown Caller” or “No Caller Id”?

“Unknown Caller” means your phone provider doesn’t know who’s calling you. On the other hand, “No Caller ID” means the caller has purposefully hidden their number, which clearly indicates an intention to remain anonymous.

What Is an “Unknown Caller”?

When your phone displays “Unknown Caller,” it means that the caller’s information isn’t reaching your device due to network issues. This could happen even if the caller is in your contact list. 

Sometimes, “Unknown Caller” appears when someone is calling you from another country because your phone service provider can’t recognize the foreign caller ID.

If you’re not expecting a call from an unknown number, it’s usually best not to answer. Important callers will likely leave a voicemail or send a message.

What Is “No Caller Id”?

When you see “No Caller ID,” it means the caller has intentionally hidden their phone number. People and organizations hide their IDs to stay anonymous for privacy reasons or work-related purposes, such as telemarketers or fundraisers. However, this feature is also used by scammers to hide their identity and carry out malicious activities.

6 Differences Between “Unknown Caller” and “No Caller Id”

While similar in that you don’t know who’s calling you, “No Caller ID” (or “Private Caller”) and “Unknown Caller” are not interchangeable terms.

The table below will show these differences to help you decide how to handle such calls and protect yourself from potential scams or unwanted interruptions:

Unknown CallerNo Caller ID
DefinitionProvider doesn’t transmit infoCaller hides their number
CauseTechnical issues, international callsCaller blocks their ID on purpose
UsageUsually unintentionalUsually intentional
FrequencyCommon with different carriersCommon in privacy/business contexts
Caller’s IntentNo clear intent to hide identityClear intent to remain anonymous
Recipient’s ActionCould be harmless or importantOften seen as suspicious

Is an Unknown Caller Always Spam? Should I Accept Unknown Caller Calls or Call Back?

No, an unknown caller is not always spam. However, many unknown calls are from telemarketers or scammers. 

Scammers often pretend to be from reputable companies, trying to create a sense of urgency to trick you into giving out personal information. Telemarketers might be trying to sell products or services you don’t need. 

While there are rare instances where legitimate callers might be flagged as unknown, it’s safer to assume the worst and act cautiously.

It’s best not to answer calls from unknown callers

When you see “Unknown Caller” on your screen, it doesn’t always mean the call is spam, but it’s wise to be cautious. 

Both Apple and Google have improved their systems to flag probable spam calls. This means that when “Unknown Caller” appears, it’s often best to assume it’s not a call you’ll want to answer.

Is *67 Sign Of a Spam Call? How to Identify Unknown Callers?

No, not all calls using *67 are spam. But, it’s wise to be cautious.

Using *67 is a common way for people to hide their Caller ID when making a call. When you dial *67 before a phone number, it blocks your number from appearing on the recipient’s phone, showing “Private Number,” “Unknown Caller,” or “No Caller ID” instead. 

This feature is widely used for privacy and is not necessarily a sign of spam. However, it can be used by scammers to conceal their identity. 

Identify Unknown Callers

Knowing who is calling can help you avoid scams and unwanted calls. Here are some easy ways to identify unknown callers:

  • Check for voicemails: Listen to any voicemail left by the caller. Legitimate callers usually leave clear messages. Avoid calling back if the voicemail sounds suspicious.
  • *Use 69 (apply for US & Canada): Dial *69 to find out the number of the last person who called you. This works on most phones and can give you the caller’s number. You can then search the number online to see if it’s linked to spam.
  • *Identify threatening callers with 57: If you get a threatening call, dial *57 right after hanging up. This will send the caller’s info to your service provider, who can then work with the police. Note that this service may cost extra.
  • Contact your phone company: Your phone company might have services to help trace unknown callers. They can give more details than *69 or *57. Check with them for options and any fees.
  • Use apps: TrapCall will show the identity of unknown callers after you decline the call. It also blocks robocalls. Or TrueCaller can help you identify unknown callers and block spam calls. It also lets you send and receive texts.
