How do you find your port number? This is a common question among users who are either troubleshooting network issues or configuring certain applications. Port numbers are essential for communication between devices on a network, as they help identify which application or service is being used. Whether you are a tech-savvy individual or someone who is just starting to explore the world of networking, understanding how to find your port number can be quite beneficial.
In this article, we will explore various methods to help you locate your port number, depending on the operating system you are using. By the end of this guide, you should have a clear understanding of how to find your port number and use it effectively for your needs.
Locating Port Number on Windows
Finding your port number on a Windows computer is relatively straightforward. Here are the steps you can follow:
1. Open the Command Prompt by pressing the Windows key + R, typing “cmd” in the Run dialog box, and pressing Enter.
2. In the Command Prompt, type “netstat -an” and press Enter. This command will display all active network connections and their corresponding port numbers.
3. Look for the port number associated with the application or service you are interested in. The port number will be listed next to the application’s name or IP address.
Locating Port Number on macOS
On a macOS computer, you can find your port number using the following steps:
1. Open the Terminal application, which can be found in the Utilities folder within the Applications directory.
2. In the Terminal, type “lsof -i -n | grep [port number]” (replace [port number] with the specific port you are looking for) and press Enter. This command will list all open files and their associated port numbers.
3. Look for the port number and the application or service that is using it.
Locating Port Number on Linux
On a Linux system, you can find your port number using the following steps:
1. Open the Terminal application.
2. In the Terminal, type “netstat -an | grep [port number]” (replace [port number] with the specific port you are looking for) and press Enter. This command will display all active network connections and their corresponding port numbers.

Using Port Forwarding
If you are experiencing network issues with a specific application or service, you may need to set up port forwarding on your router. Port forwarding allows you to direct incoming network traffic to a specific device on your network, which can resolve connectivity problems. Here’s how to find your port number for port forwarding:
1. Log in to your router’s web interface by entering its IP address in a web browser.
2. Navigate to the port forwarding section.
3. Enter the port number you wish to forward, along with the IP address of the device that will be receiving the traffic.
4. Save the settings and test the connection to ensure that port forwarding is working correctly.
In conclusion, finding your port number is a valuable skill that can help you troubleshoot network issues and configure applications effectively. By following the methods outlined in this article, you should now be able to locate your port number on any Windows, macOS, or Linux system.
