Identify the Owner of a VOIP Number

Voice over Internet Protocol (VOIP) numbers have become increasingly common. With the ease of making calls over the internet and the widespread availability of internet connections, many individuals and businesses have embraced this technology for its convenience and cost-effectiveness. However, the anonymous nature of VOIP numbers has also made them a popular choice for scammers and spammers, who exploit the ease of spoofing caller IDs. If you have ever received a suspicious call or missed an important one, you may find yourself wondering how to track and identify the owner of a VOIP number. In this article, we will explore various methods and tools that can help you in your quest.

Is it Possible to Trace a VOIP Number?

Tracing the owner of a VOIP number can be challenging due to the potential for caller ID spoofing. While traditional landline numbers are often associated with physical addresses, VOIP numbers are not bound by the same requirements. However, this does not mean that tracing a VOIP number is impossible. By utilizing certain techniques and tools, you can increase your chances of uncovering the identity behind a VOIP number.

Method 1: Reverse Phone Lookup

One of the easiest and fastest ways to find the owner of a VOIP number is by using a reverse phone lookup tool. This method works similarly to a Google reverse image search. By entering the VOIP number into a reverse phone lookup application, you can obtain valuable information such as the owner’s name and address. Several online applications offer this service, some of which are free while others require a fee for additional features.

It is important to note that reverse phone lookup tools can also help you determine if a number has been spoofed. This feature can be particularly useful in identifying potential scam calls. Additionally, some tools offer batch search capabilities, allowing you to perform multiple searches at once, which can be beneficial for businesses or individuals dealing with a large volume of phone numbers.

Method 2: Contact the VoIP Service Provider

If you receive an unknown call from a VOIP number, reaching out to the associated VoIP service provider can be a helpful step in tracing the owner. Provide the time of the call and the phone number to the provider, who may be able to track down the owner. However, it is important to keep in mind that if the caller used a fake IP address or a third-party service to make the call, the provider may not have access to the necessary information.

Tracing the owner of a fixed VOIP number, which is associated with a physical address, is generally easier than tracing a non-fixed VOIP number. Fixed VOIP numbers require a physical address to be assigned to the number, making it more straightforward to identify the owner.

Method 3: Utilize Packet Analyzers

Packet analyzers can be a valuable tool for tracing VOIP numbers, particularly if you use a hardphone or softphone in your communication setup. These phones operate using the Session Initiation Protocol (SIP) and connect to a server or proxy. By installing a packet analyzer and enabling the SIP filter, you can capture data about incoming calls, including the IP address and CNAM information. This method allows you to trace the origin of the call and potentially identify the owner of the VOIP number.

It is worth noting that this method requires setting up the packet analyzer before receiving a call. Therefore, it may not be suitable for numbers that you do not anticipate receiving calls from or numbers that you have not previously recorded.

Method 4: IP Address Lookup

If you have access to the IP address associated with a VOIP number, you can perform an IP address lookup to gather information about the owner. While an IP address lookup may not provide as much detail as a reverse phone lookup, it can reveal the location, internet service provider, and domain name associated with the IP address. With some investigation and detective work, you may be able to connect these pieces of information to identify the owner of the VOIP number.

It is important to note that this method can be time-consuming and may require additional research to obtain accurate results. Therefore, it is best utilized as a last resort.

Method 5: CNAM Lookup

CNAM lookup, also known as Caller Name Lookup, can provide valuable information about the owner of a VOIP number. While the caller ID can easily be manipulated, CNAM data is more challenging to fake. By performing a CNAM lookup, you can retrieve the CNAM data associated with a phone number. However, it is worth mentioning that CNAM lookup may require coding skills or the assistance of your VoIP service provider.

To conduct a CNAM lookup, you may need to provide your VoIP service provider with the specific CNAM you are searching for. It is important to note that some providers may require justification for conducting a trace, particularly if you have received scam calls from the number you are tracing.

Method 6: Access Call Logs

Checking your call logs can provide valuable information about incoming calls from VOIP numbers. Similar to traditional phone bills, VOIP service providers maintain call logs that document all calls made and received. By reviewing your call logs, you can gather details such as the time of the call and the specific VOIP number. This information can then be used in conjunction with other tracing methods to identify the owner of the VOIP number.

Method 7: Automated Service *69

An automated service known as *69 can also assist in identifying the owner of a VOIP number. By dialing *69 on your phone, you can access information about the last call, including the time, the VOIP number, and the location of the call. This method can be particularly useful when the caller has blocked or hidden their ID.

Method 8: Seek Assistance from Law Enforcement

If you are dealing with spam calls, harassing calls, or suspect that the VOIP number may be associated with illegal activities, it is advisable to involve law enforcement. Local law enforcement departments can investigate these matters and assist in identifying the owner of the VOIP number. Make sure to provide them with all relevant information, including call logs and any evidence of abuse or threats.


Tracing the owner of a VOIP number may require some effort and the utilization of various methods and tools. Reverse phone lookup, contacting the VoIP service provider, utilizing packet analyzers, performing IP address lookups, conducting CNAM lookups, accessing call logs, using automated services like *69, and seeking assistance from law enforcement can all contribute to identifying the owner of a VOIP number. By combining these methods and employing persistence, you can increase your chances of successfully tracing a VOIP number and uncovering its owner.
