    What is a Private Phone Number? 

    A “Private Number” is when the caller has intentionally blocked their personal number from coming up on caller ID. Private numbers are also known as unlisted numbers or an anonymous source call.

    Depending on the make and brand of your smartphone, your service provider, or if your number is for a landline, a private number might show as “Private,” “Private Caller,” “Private Number,” or even “Unknown Number.” Most masked calls coming from inside the United States are labeled this way. A lot of phone call spammers use VoIP numbers to solicit people because they are able to create thousands of numbers on the fly.

    Private numbers are used so a caller can block their number from showing up on your caller ID, for example, by entering *67 before making the call. Most telephone carriers offer this caller id blocking service and can be used on a per-call basis.

    Landline telephone services and some wireless carriers provide features to continuously block caller id for outgoing calls. Subscribers generally have to pay monthly for this service, but when their number is registered with their provider as “private,” they don’t have to enter *67 (activates call block on most phones) before making a call.

    Are private numbers dangerous?

    There are various reasons calls are private, but numerous solicitations and spam calls abuse private numbers or unknown numbers to catch you off-guard.

    Why Private Phone Number Phone Calls are a Concern?

    With the number of robocalls, solicitations, and fraud happening today, it’s important to be cautious when answering unidentified calls.

    How do you know if the “private number” call you are receiving is not a spam caller? Here are some tips for unmasking private numbers and how to deal with them.

    How to Deal with and Call Trace Private Phone Numbers

    How to handle private numbers

    Let the Private Call Go to Voicemail

    When you get a call and see on your caller ID information that it is a private caller, let the call go to voicemail (this is your best bet!). When in doubt, don’t answer the phone; send it to voicemail. If the private caller leaves a message, you can then review the voicemail and decide if it’s a legitimate call.

    I personally use this method all the time, especially with voicemail transcription offered by most providers. You don’t even have to listen to the voicemail. Transcription provides a written copy of the voicemail so you can read and review it. Sending private calls to voicemail is definitely the easiest way to handle these types of calls.

    How to call back a private number? Dial *69 to Call The Private Number Back

    How to call someone private and how to call back unknown number? If the caller did not provide a call back number, you can dial *69 call back last number. Using this feature does not give you the number but actually calls the number immediately back. I personally would not do this because I feel that legitimate callers will provide their contact information.

    So my advice would be only to use this feature if you absolutely have to return the call and the caller forgot to leave their number, or if they did, but you couldn’t hear all or part of the number. This feature doesn’t always work and can only be used for the last call received, but it is worth trying to reach the caller.

    How to call back a no caller id, restricted number or unknown number?

    If your incoming call had no caller id which means it might be private, unknown or restricted, you can still try entering *69 on your phone and see if your call can be returned.

    Purchase Anonymous Call Blocking

    Purchase or subscribe to Anonymous Call Blocking or block calls from unidentified callers meaning to spam you. Most telephone service providers offer this service either for free or for a small monthly fee. If you enable this service, you will no longer receive anonymous or private number calls. You will not hear a ring or any other notification that you receive a call from a private or unknown number. In fact, callers will receive a message that you do not accept anonymous or private number calls, and they should disable it if they want to get through to you.

    This is a great option for people who are inundated with spam calls. I think of this as a last resort option for customers. The downside of this feature is that you might miss calls that are legitimate and important. For example, many doctors and other healthcare professionals have private numbers to return calls from their cell phones or home phones.

    When private numbers are permanently blocked, you don’t get a call, but the blocked caller will receive a recording that states the recipient does not accept private or unknown calls. Permanently blocking calls can be an issue if the caller does not know how to disable caller id blocking, resulting in a considerable challenge to get in touch with you.

    Check Cell Phone Call Records and Logs

    Check your cell phone call records to find private phone numbers. Many cell phone carriers include a complete list of incoming and outgoing calls by date and time on your monthly cell phone bill.

    On occasion, a phone number might show up on your call log that appears as an unknown or private caller on your caller ID. This option requires that you know the date and time the call came in to check it against the call logs.

    Use a Service to do a Reverse Number Lookup to get the name or company before you call back

    If you have a number only and no information like a name, you can use a reverse lookup to find additional information. There are some paid reverse lookup services such as and Sometimes, Google has some of the information like a name in some of its natural search results. A reverse lookup is generally a good option when the number belongs

    to an individual or known business. In fact, there are many way to find names, addresses and phone using just the web!

    Check if Phone Provider Offers Call Tracking

    Some phone providers have a call tracking feature that can be used to find out the name and number of a private caller. The feature was initially developed to trace calls of a harassing or threatening nature.

    This call tracking feature can be used by hitting *57 from a landline or #57 from a cell phone after receiving an unknown call and then follow the prompts. There is generally a small charge for this call tracing feature (sometimes called last call return). These call traces are advantageous if you need to file any legal action against the caller and may provide information so you can call them back.

    Tips For Tracing Threatening Private Phone Numbers

    Private Call Spam

    A common question is “can a blocked number be traced?”. If you are receiving threatening, intimidating, aggressive telemarketers, scam, or scammer calls from a private caller ID, contact your cell phone provider and request to speak to its security department, which (depending on the provider’s policies) may set up a call trace or request you file a complaint with local law enforcement. Neither course of action means the personal information associated with a private caller ID (such as the person’s name, phone number, address) is released to you; however, it means authorities will take action on your behalf to halt that caller from making further phone calls to you.

    If you find a phone number for an unknown caller, you can permanently block the number on your cell phone. Go to your recent calls log, find the number, click the “i” circle to the right of the number, scroll down and click “Block this Caller,” and tap the “Block Contact” on the pop-up. These last two options are in red to make certain you want to block this number. If you blocked a number by mistake, or change your mind, find the number, and then in the information screen, scroll down and click “Unblock this Caller.”

    How to Make a Private Phone Call or Call a Number Anonymously?

    How to call a number privately or call a number anonymously? After making such a fuss about receiving private calls, why would there be an occasion to make a private call? We aren’t sure, but there are still ways to accomplish this.

    1. Dial *67 and then the phone number you are calling. By dialing *67 before making your call, your number will be hidden and will not show up on the receiving caller ID. This service is generally free and works on both landlines and mobile numbers.
    2. Block your number permanently by registering for a private number. This service is generally offered for landlines only, and there is a monthly fee to have a private, unregistered number, also called an unlisted number. A word of caution, having a private number may limit who receives your calls because, as noted earlier in the article, many people do not accept calls from private, unlisted numbers. To unblock your number, you can use the same tip above and dial *67 before making your call. When doing this in reverse, *67 will unblock an otherwise private number.
    3. You can also hide your number by default on your cell phone by going to your IOS Settings, then Phone, Show My Caller ID, then change to show or not show your phone number. If any calls cannot go through because your number is unknown, just dial *82 before the phone number to unblock your own number.
    4. Some cell phone carriers also provide the option to make your number permanently private, just like landline numbers. Reach out to your carrier and see what they provide and a fee for the service. You should also check your monthly statement to make sure you are not already subscribed.
    5. Sign-up to a free phone service app and use that number to make private calls.
