How to Find IP Address By Phone Number

Finding an IP address using a phone number is a matter that many people search for when they receive unknown calls, VoIP scam calls, or suspicious messages. While a phone number does not directly reveal an exact IP address, it can help you collect useful network and location-related clues when combined with the right tools and methods.

Today, most calls (especially spam and scam calls) use VoIP services, and these calls travel through internet servers instead of traditional mobile networks. As a result, digital footprints, such as ISP type, server region, and IP ranges, can sometimes be identified indirectly.

In this guide, you’ll learn how lookup tools, IP loggers, manual searches, and network commands work together to provide a clearer picture of where a call may be coming from. These methods are commonly used by cybersecurity researchers, digital marketers, and fraud investigators to analyze unknown callers.

To make this easier, you can try the TechniqueHow’s caller number tracker tool. With this tool, you simply enter a phone number and instantly get:

• Approximate location (country, region, city level)
• Server or ISP information linked to the number
• Multiple IP blocks shown as examples only (CIDR format)

What is an IP Address?

An IP address is a network identity given to a device when it connects to the Internet or any local network. It works like a routing label, helping data know exactly where to go and where it came from. Every online action, i.e. opening a webpage, sending a message, or using an app, depends on this address to function properly.

If a device had no IP address, it would be invisible online. Websites wouldn’t know how to respond, apps wouldn’t load, and online services wouldn’t be able to communicate with it.

Modern smartphones usually operate with two IP addresses at once:

Local (Private) IP – Assigned inside your Wi-Fi or internal network. It is used only between devices on the same network and never appears publicly.

External (Public) IP – Assigned by your internet provider. This is the address seen by websites, servers, and online platforms.

The public IP may change frequently, especially on mobile networks, while the private IP remains stable during a network session.

Here are two main formats:

• IPv4 → short numeric format (e.g., 192.168.1.1).
• IPv6 → longer alphanumeric format, designed to replace IPv4.

Every smartphone usually has:

• Private IP → works inside your Wi-Fi or local network.
• Public IP → visible to websites, apps, and online services.

How to Find IP Address By Phone Number?

Many people mix up IP addresses, phone numbers, and emails, thinking they all reveal the same information. In reality, they work very differently. A phone number does not directly expose an IP address, but it can help you find digital clues that point toward network location, ISP type, or VoIP usage.

In this guide, you’ll learn practical, step-by-step methods to gather those clues using VoIP lookup services, IP logging tools, manual online searches, and basic system commands.

1. Call Number Tracker App

Many spam and scam calls today use VoIP (Voice over Internet Protocol) instead of traditional mobile networks. VoIP numbers often leave traces across public databases, people-search platforms, and caller directories.

By checking these sources, you can learn whether a number is linked to online activity, virtual phone services, or known spam behavior.

A. Whitepages

Whitepages is a widely used online directory that helps identify details connected to phone numbers, including carrier type, general location, and spam reputation. While it does not directly reveal an IP address, it plays an important role in understanding whether a phone number is linked to VoIP services, virtual numbers, or traditional telecom networks. This distinction matters because VoIP numbers are internet-based and often associated with servers, ISPs, and rotating IP ranges rather than a fixed physical location.

When dealing with unknown or suspicious calls, Whitepages helps you quickly decide whether a number looks legitimate, recycled, or potentially risky, which is a strong starting point before moving to deeper IP-related analysis.

Here’s how to use it effectively:

Step 1: Visit the official Whitepages website using any browser on desktop or mobile.

Step 2: Enter the full phone number (including country code, if applicable) into the search bar and start the lookup.

Step 3: Review the summary details shown on the results page. This may include:

• Carrier type (mobile, landline, or VoIP)
• General location (city or region level)
• Spam or fraud risk indicators
• Whether the number is frequently reported by users

Step 4: Just look at the labels such as “VoIP number”, “non-fixed line”, or “high spam risk”. These labels strongly suggest the number uses internet-based calling systems.

If available, check related information such as associated names, past locations, or business tags. These details can be cross-checked with social media or manual Google searches.

B. Spokeo (Reverse Lookup)

Spokeo gathers data from public records, online profiles, and digital directories. While it does not show an IP address, it helps you build context around a phone number.

Step 1: Visit Spokeo’s official website using a browser, sign up, and select the phone number search option to start.

Step 2: Now, type the phone number into the search field, then press Enter to initiate the lookup automatically.

Step 3: Spokeo displays available details, including name, linked addresses, social media, and sometimes even photos for context.

Step 4: Check the available addresses and email connections to strengthen leads related to that person’s digital presence online.

You can save results and cross-check them with social searches or other lookup platforms for confirmation or added details.

Remember: Spokeo is a paid service, so full details may require purchasing a report subscription plan for access.

2. Online Log Tool: Grabify

Another indirect way to find someone’s IP address is by using an IP logging service like Grabify.

This tool allows you to create a custom tracking link that records the IP address of anyone who clicks it. The beauty of this method is that it doesn’t require advanced technical skills. Let’s start.

Step 1: First, open the Grabify IP Logger website and find an article or video and copy its link, which is catchy enough to interest any user to open it.

Step 2: You’ll need to paste the copied link into the white input box and click on Create URL, and proceed.

Step 3: You’ll be taken to the next page, where you’ll be able to find the shortened link as New URL. Copy that link.

Step 4: You’ll also see the tracking code that you need to remember so that you can use it later and send the copied link via SMS to the person whose IP you want to trace.

Step 5: Wait for the user to click to open the link, and as soon as the user opens the link, Grabify records its IP address and directs back to the original topic of the link.

Step 6: Next, head on to Grabify’s homepage, enter the tracking code in the white input box, and click on Tracking Code/Access Link.

From the access link, scroll down to see the Results. It will display the number of users that have clicked on the link as well as their other details like IP address, date and time, country, user agent, etc.

You can also enter the IP address into the TechniqueHow’s IP lookup tool and see more accurate details, including ISP and more.

3. Try Manual Search (Social Media or Google)

Manual searching can be powerful because people leave digital traces online, and that is why Google search, social media platforms, and reverse image lookup are common tools to start with.

This approach doesn’t directly reveal IP addresses but helps gather leads that may eventually point to IP-based details.

Many investigators start with simple Google searches before moving to technical tracing.

Step 1: Enter the person’s email address directly into the Google search bar and check the results for possible connections.

Step 2: Now, try usernames used by the person across platforms; check if accounts are linked under the same name.

Step 3: Here, upload their profile picture to Google Images or TinEye for the reverse image search identification process.

You can also check on the social media platforms like Facebook, Instagram, or Twitter for activity linked to searched details.

Now, cross-check email, username, and images to create connections between accounts belonging to the same person online.

On social platforms, IP data helps find fake accounts, cyberbullying, or scams. Combined with usernames, emails, or activity patterns, it gives a clearer picture of who is behind an account. By combining IP addresses with social data, investigators can connect accounts, find hidden links, etc.
