Unknown Caller: How to Identify and Block an Unknown Number Calling

Many of the 100 million Americans using landlines today have been prey to phone scams, losing an average of $350 per person in 2021. With the number of spam calls increasing yearly, *60 to block spam calls on your landline phone is a short-term solution.

This article provides information on the following:

  • How to identify and block unwanted callers
  • An alternative to manual blocking: Community Phone spam-blocker services.

Who Is an Unknown Caller?

When you receive calls from an "Unknown Caller," it may mean that the number was not interpreted correctly by your telecom operator. In most cases, these calls are spam that you should not answer. You can let the call go to voicemail and respond if it is essential.

Call Tracing: How to Identify a Phone Number

Identifying unknown callers can help you protect yourself, your business, and your loved ones from scam calls.

1. Check Caller ID

If you suspect a spam call, check the caller ID after you hang up or when the call has stopped ringing.

Each telephone service provider has a different caller ID option. Depending on your provider, there might be a fee for using this service, and you may have to enable the service. Your service provider may need to rectify the issue if you have never seen a caller ID on your phone.

2. Dial *57

Phone companies provide anonymous caller ID service to customers because they keep records of previous calls. You can use the *57 services to find the unknown phone number and possibly other details if you have a phone carrier.

You will hear a recorded message when you dial *57 and get instructions to follow for a trace. You will receive a message if the trace is successful and may have to pay for it. Unfortunately, only some carriers offer this service and those who do often charge a fee.

3. Use Apps

A caller ID app reveals the caller's name even if you don't have their contact information stored in your phone. Many apps exist for both Android and iOS that identify the caller.

Truecaller (Android, iOS)

The Truecaller app can alert you to calls from unknown numbers and numbers that phone scammers frequently use. You can block unwanted callers or texts and search for unknown numbers using the app.

Trapcall (Android, iOS)

You can use Trapcall to identify hidden incoming calls and 'unmask' their identities. With this app, you can record your calls, block unwanted numbers, and block any number that bothers you. Android and iPhone users can download it for free.

How to Block an Unknown Number

Use one of these methods to block calls on a landline, Android phone, or iPhone.

Block Unknown Calls on Landline

Most options for blocking phone numbers on your landline phone require that you receive the call first. Manual blocking of numbers depends on your phone's capacity and service provider. Many landline providers do not provide spam-blocking services.

Community Phone understands how proactively blocking spam calls can protect you, your business, and your loved ones. They have different spam-blocking options to cater to people's unique needs.

Community Phone's Spam Call Blocking

Community Phone's Spam Call Blocking

  1. When you sign up for the Community Phone spam blocker, your phone will not ring immediately when a call comes.
  2. The caller will hear a recording that asks them to press a number.
  3. Robocalls start playing their recording the minute they hear a voice other than the phone ring.
  4. As soon as they start playing their recording, mistaking the Community Phone recording as a person, it gets flagged as a robocall.
  5. Community Phone disconnects the call and blocks the number from reaching you again before your phone rings.
  6. If the caller follows the instructions and your phone rings, you can always let the call go to voicemail with Community Phone's voicemail feature. You can choose to respond to the voicemail at your convenience.

Community Phone Whitelisting Services

This option is ideal for people with dementia and other ailments which would not want to be inconvenienced by unwanted calls.

  1. Contact Community Phone customer care at 866-914-1428.
  2. Compile the list of numbers you want to accept calls from and share it with the rep.
  3. Community Phone will whitelist these numbers for you.
  4. Your landline will allow calls only from those numbers and block calls from all other numbers.

Manual Call Blocking

Spam call-blocking in phones allows you to block numbers after receiving the call. These providers usually suggest using the *60 code as explained below:

  • Pick up your receiver and press *60
  • A message will guide you through blocking a number
  • You can block the most recent call by dialing #01#
  • Using #, dial the number (including the area code), followed by # to block the other number.

Some phone models, like the CPR V5000, allow you to block up to 1500 numbers. However, you will have to block these numbers one at a time on a landline phone.

Block Unknown Calls on Android

On an Android phone, "unknown" does not refer to numbers not saved in your contacts. You can block unknown numbers on an Android phone by following the steps below.

  • Click on the Phone app.
  • Click the three-dot menu, then select Settings.
  • You can block private and unknown numbers on your phone by clicking "block unknown/hidden numbers."

Block Unknown Calls on iOS

You can disable unknown calls using the iPhone app by selecting the "Silence Unknown Callers" option.

  1. Select Settings > Phone > Silence Unknown Callers
  2. On the next screen, toggle ON Silence, Unknown Callers.
  3. Silence Unknown Callers on iPhone
  4. This feature can, however, block genuine callers because of not listing them in your contact list.

Whenever you receive a call from an unknown number, it will be sent directly to voicemail and appear in your recent call list.

All the apps and phone feature only allow you to block numbers one by one manually or even block open calls due to app limitations.

Is there any difference between an Unknown caller and no caller ID?

The term "No Caller ID" refers to the caller hiding his mobile number using a unique feature on his device. In contrast, "Unknown Caller" refers to a telephone number that telecom companies cannot interpret.

How do I identify an unknown number?

When you receive a call and need to know who the caller is, one classic method is to call back and reconnect, but this is not an advisable option if the call is possibly spam. Using a reverse phone lookup site can also find out who called you.

What does it mean when an unknown number is calling?

When an unknown number calls, the caller has dialed *67 before the number to block their called ID.

Is an unknown caller always spam?

Unknown callers are mostly spam. Although engaging with anonymous users is okay, we suggest you not pick up the call.

Can you trace an unknown caller?

In most cases, it is possible to trace private, blocked, and restricted numbers. Due to anonymous data, unavailable or out-of-area calls are not traceable.

Why do I keep getting calls from an unknown number?

Entering numbers on particular websites or databases may trigger spam calls. You always were cautious when entering your phone number into databases because they are often open to thieves and scammers.

Can you block calls from private numbers?

Yes, you can block calls from private numbers using the following steps:

  1. Open the Phone App
  2. Tap 3 dots from the Keypad tab
  3. Select: Settings
  4. Go to Block Numbers
  5. Turn on: Block Unknown/Private Numbers

Does * 61 block unwanted calls?

Yes, *61 can help you block unwanted calls.


You can permanently block calls by adding numbers to the Do not call registry and downloading anti-spam software. You can block specific callers from calling your phone using this feature.

However, most landline phones have limiting call-blocking features, as you have to pick up the call before blocking it. Get Community Phone, your answer to blocking marketing calls on a landline.
