Internet statistics say that there are 5.16 billion Internet users worldwide. With this vast number of users, most of us probably already know how to make calls using Internet apps.

But did you know that a phone number can be attached to online calls? It's called a VoIP number, and a person who uses this is a VoIP caller

VoIP is short for Voice over Internet Protocol. A VoIP number is an actual telephone number operating on an internet connection instead of through local telephone lines. They’re basically virtual phone numbers that many reliable companies provide.

If you're receiving calls with this number but need to know who's on the other end, there's a way to find out who they are. 

In this article, discover the different ways you can look up an unknown VoIP number. 

Methods of Tracing Unknown VoIP Numbers

There are multiple ways you can do a VoIP reverse phone search:

  1. Your VoIP service provider
  2. Social Catfish and other reverse phone search websites
  3. CNAM Lookup
  4. Packet Analyzers
  5. IP Address Lookup

These are reliable ways to help you find out who owns the VoIP number that is trying to reach you. It would be good to get a grasp of how to do this since there have been many cases of anonymous calls both from Android phones and iPhones. Some of these applications and websites offer their services for free, while others require payment. 

Using a VoIP Service Provider

A VoIP service provider is a business entity that offers VoIP services directly to business and individual customers. 

Here's how a provider might help you identify the owner of a number:

  1. Note the caller ID and the time you received the call. 
  2. Contact your VoIP service provider and give them the necessary information.

Your provider will be able to track the number owner for you.

The caller you are trying to track down may have a registered caller ID or IP address they use to make calls. If they use a fake IP address or a third-party ID, it can be harder to know their identity. 

CNAM Lookup

There are two identifiers when making calls: a phone number and a CNAM. 

The CNAM is called Caller ID Name, which is usually a 15-character string. It helps display the calling party's name and phone number to help users quickly identify a caller.

You can use a CNAM lookup tool to get the CNAM data for a phone number. A CNAM lookup tool can be free or charge you low fees per query or monthly. Some examples are:

  1. Bulk Vs
  2. CallerIDservice
  3. CallWithUs
  4. Digital Conceptions Canada
  5. Multitel

Among these applications, Bulk Vs., CallerIDservice, and Multitel offer free queries.

Searching for the CNAM will only work if you have your VoIP number. It can be tricky to find the phone number's owner with just the caller ID since, unfortunately, this can be faked.

The CNAM, on the other hand, is difficult to fake. Many spoofers don't even bother trying to alter it. You can also do a CNAM query if you have some coding skills. 

IP Address Lookup 

An IP means Internet Protocol, which refers to a collection of rules governing the format of data transmitted over the Internet.

The 'address' refers to a unique number linked to all activities you do online. This address is similar to a return address on a letter you'd send out, only the data-sending occurs much faster across the internet.

For example, you might see the IP address displayed on your VoIP phone screen. This display gets it from your router. This protocol is what assigns IP addresses within a computer network. It is possible for an individual to hide their IP address 

Also, you can use a reliable website that can obtain IP addresses, such as Searchbug: 

Type the address in the box, and you're ready. Wait for the results and the instructions to come in.

This tool will tell you the IP address location, the internet service provider, and the domain name.

These pieces of information can help you have an idea about who might be calling you or where they’re coming from.  

Social Catfish Reverse Phone Lookup

There are other ways to look up phone numbers but one of the best ways to do it is through Social Catfish. 

Social Catfish is a website that uses images, emails, and social media profiles to investigate the online dating world; it also uses phone numbers.

Its reverse phone search tool can help you verify the person behind the phone number you have. 

It can also help you find friends or connections. Here's how to search: 

1. Click the Phone tab

Other Reverse Phone Search Websites

Several reverse phone number lookup websites and tools offer their services for free. Some examples are USPhoneLookup, USSearch, and Numlooker.

Using any of these websites is pretty straightforward; their layouts are simple and easy to use.

Go to any of the links above, and with the number you have, type it in the search box on the website. Wait a few minutes for the results. 

You’ll see that most of these sites offer comprehensive results. It may be a matter of which pieces of information you’d like to know aside from the name of the person behind the number. 

Most of these sites will ask you to provide your email address to access the results. With this comes the warning that you should not use any info you receive for illegal purposes.

Some paid websites that offer reverse phone lookup services are BeenVerified and Spokeo. While they require payment, they're also relatively simple as Social Catfish. 

Installing Packet Analyzers

Packet analyzers trace the numbers on SIP or Session Initiation Protocol phones. SIP is a signaling protocol. It manages voice communications and multimedia sessions. You can find these phones in call centers.

You can categorize packet analyzers according to softphones and hard phones.

A packet analyzer is a program that intercepts or logs network traffic. On softphones, the packet analyzer's SIP filter will display the IP address and Caller ID Name of the VoIP owner.

You can use a packet analyzer on your local router and filter for hard SIP and IP on hard phones. You can trace the number on your own using an Internet Telephony Service Provider.

How To Trace a Non-Fixed VoIP Number

There are two types of VoIP numbers: fixed and non-fixed. Non-fixed VoIP numbers are more challenging to trace than fixed numbers because the latter requires a physical address to be assigned to the number. On the other hand, non-fixed ones have no address requirement. 

To get a non-fixed VoIP number, you only need an email address. Though tracing it can be difficult, you can use a caller ID lookup service. You have a good chance of getting information from that service that matches that of the caller.
