Have you received a call from an unknown VoIP number and wondered who was behind it?

Whether it was a missed business call, a suspected scam, or repeated unwanted calls, identifying the caller isn’t always straightforward. VoIP numbers operate over the internet, making them more flexible and sometimes harder to trace.

The good news is that there are several legitimate ways to gather information about a VoIP number. While you may not always discover the person’s name, you can often identify the service provider, caller ID information, business details, or whether the number has been reported as spam.

This guide explains the safest and most effective methods to help you find the owner of a VoIP number.

Difference B/W VoIP & Regular Number

Before searching for the owner, it helps to understand what makes a VoIP number different from a traditional phone number.

A regular phone number is connected to a mobile carrier or landline network. A VoIP (Voice over Internet Protocol) number makes and receives calls through an internet connection instead of the traditional telephone network.

VoIP Number	Regular Number
Uses an internet connection	Uses cellular or landline network
Can work from almost anywhere	Usually tied to a SIM card or physical line
Easy to move between devices	Normally linked to one phone
Common for businesses and virtual phone systems	Common for personal use
May be harder to identify	Usually easier to trace through the carrier

Fixed vs. Non-Fixed VoIP Numbers

Not all VoIP numbers work the same way.

1. Fixed VoIP Numbers

A fixed VoIP number is registered to a physical address. Businesses often use these numbers because they appear more reliable and are associated with a specific location.

These numbers are generally easier to verify since they are linked to an address during registration.

2. Non-Fixed VoIP Numbers

A non-fixed VoIP number is not tied to any physical location.

Users can create and use these numbers from almost anywhere with an internet connection. Virtual phone services frequently offer non-fixed numbers because they provide flexibility for remote workers and international businesses.

Since there is no fixed address, these numbers are usually more difficult to trace back to an individual.

Method to Find the Owner of a VoIP Number

No single method guarantees you’ll identify every caller. However, combining several of the techniques below gives you the best chance of finding useful information.

1. Use a Reverse Phone Lookup

A reverse phone lookup is usually the fastest place to start.

Simply enter the phone number into a reputable lookup service. Depending on the available records, you may see:

Owner or business name
Line type (VoIP, mobile, or landline)
Carrier or provider
General location
Spam reports

Keep in mind that some services only provide basic information for free, while detailed reports may require payment. New VoIP numbers or private accounts may not return any owner information.

Using a Reverse Phone Lookup

Suppose you receive a call from +1 (415) 555-1234, but you don’t recognize the number.

Here’s what you can do:

Copy the complete phone number.
Visit a reputable reverse phone lookup website, such as Whitepages, Truecaller, or Spokeo.
Enter the number into the search box.
Review the available results.

2. Check the Number With a Caller ID Service

Modern smartphones include built-in caller identification features, and many third-party apps also maintain large caller databases.

If the caller has been identified by enough users, the app may display:

Business name
Caller name
Spam warning
Fraud alerts

Remember that caller ID isn’t always accurate. Scammers sometimes use caller ID spoofing to display fake names or trusted numbers. Treat caller ID as a clue rather than proof of identity.

Here are a few popular Caller ID services:

Truecaller (Android, iPhone, Web)
Hiya
CallApp
Google Phone App (on supported Android devices)
Apple Live Caller ID (supported regions and apps)

3. Identify the VoIP Provider or Carrier

Many phone lookup tools can tell you which carrier currently serves a phone number.

While knowing the provider won’t reveal the subscriber’s identity, it helps you determine:

Whether the number is VoIP
Which company issued the number
Whether the number has been ported between providers

This information becomes especially useful if you later need to report abuse or contact the provider.

You can use a carrier lookup tool such as Twilio Lookup, Telnyx, or other reputable phone-number lookup services.

4. Check CNAM Information

CNAM stands for Caller Name.

In supported regions, telecom providers maintain caller name databases that can display a business or person’s name when a call arrives.

A CNAM lookup may reveal:

Business name
Individual name
Caller label

However, CNAM records are not always current and are not available for every country or carrier. They should be treated as supporting information rather than definitive proof of ownership.

5. Search the Phone Number on Google

Sometimes the simplest method works surprisingly well.

Search the complete phone number using quotation marks.

For example:

“123-456-7890”

You may discover the number listed on:

Company websites
Customer support pages
Online forums
Public directories
Scam reporting websites

If multiple websites mention the same business, the information is generally more reliable than a single listing.

6. Check Business Directories and Social Profiles

Many businesses publish their contact numbers online.

Search the number on:

LinkedIn
Facebook
Yelp
Google Business Profile
Company websites

If the number belongs to a business, these platforms often reveal:

Company name
Address
Website
Business hours

Personal numbers are much less likely to appear publicly because of privacy protections.

7. Check Your Own Call Logs and VoIP Records

If you’re already using a VoIP service, review your call history.

Most providers record:

Date
Time
Duration
Incoming number
Missed calls

These details can help you match the suspicious call with other information you find during your investigation.

Business VoIP systems may also include additional call analytics and reporting features.

8. Contact the VoIP Provider

If the calls involve harassment, fraud, or repeated abuse, contact your VoIP provider.

Provide as much information as possible, including:

Phone number
Date and time
Call duration
Screenshots or recordings (if available)

Providers may investigate abuse reports internally, although they generally cannot disclose another customer’s private information because of privacy laws.

9. Report Serious or Suspicious Calls to the Appropriate Authorities

If someone is threatening you, attempting fraud, or impersonating a government agency, report the incident instead of trying to investigate on your own.

Depending on your country, you can report:

Scam calls
Harassment
Identity theft
Financial fraud
Robocalls

Law enforcement agencies can work directly with telecom providers when necessary as part of an official investigation.

Is It Legal to Look Up a VoIP Number?

In most countries, performing a reverse phone lookup is legal when you use publicly available information or legitimate lookup services.

However, there are important limits.

You should never:

Attempt unauthorized access to someone’s account
Use private information for harassment
Misuse personal data
Assume lookup results prove someone’s identity

Most lookup services collect information from public records, telecom databases, and business directories. Even then, the results should be verified before taking any action.

FAQs – Finding the Owner of a VoIP Number

Q1. Can I find a VoIP number’s location?

Usually, you can only identify a general region or the provider serving the number. A VoIP number does not reveal someone’s real-time location.

Q2. Are VoIP numbers traceable?

Yes. VoIP numbers can often be traced to a service provider, carrier, or business.

Q3. Can Google identify a VoIP number?

If the number appears on business websites, directories, forums, or public profiles, Google may help you identify the owner.

Q4. Can I find the owner of a VoIP number for free?

Free tools may reveal basic details such as the carrier, line type, or business listing. Complete owner information is not always available, especially for personal or newly created VoIP numbers.

Q5. Can police trace a VoIP number?

During an official investigation, law enforcement agencies can request records from telecom providers when legally authorized.

Q6. Does a VoIP number mean it is a scam?

Millions of legitimate businesses use VoIP every day because it is affordable and flexible. While scammers may also use VoIP services, having a VoIP number alone does not indicate fraud.

Q7. Can someone hide their identity using a VoIP number?

Virtual numbers, privacy settings, and caller ID spoofing can make identifying the caller more difficult. However, legitimate investigations and provider records may still help identify abusive users when required by law.

Final Verdict – Finding the Owner of a VoIP Number

Finding the owner of a VoIP number isn’t always easy, but it’s often possible to gather useful information.

Start with a reverse phone lookup, verify the carrier, search the number online, review caller ID details, and check business directories. If the calls involve fraud, harassment, or threats, contact your VoIP provider and report the incident to the appropriate authorities instead of trying to investigate further on your own.

No single lookup can guarantee the caller’s identity, but combining multiple legitimate methods gives you the best chance of discovering who is behind the number while respecting privacy laws.
