Understanding your Wi-Fi MAC address, or Media Access Control address, might seem like a technical deep dive, but it’s actually a pretty straightforward process. Your MAC address is a unique identifier assigned to your network interface card (NIC), which allows your device to connect to Wi-Fi. Think of it as your device’s physical address on the network. Knowing this address is useful for various reasons, from network troubleshooting to setting up parental controls or whitelisting your devices on a network.
Why Do You Need to Find Your MAC Address?
You might be wondering, why bother finding my MAC address? There are several compelling reasons.
Firstly, network security often relies on MAC address filtering. Many routers allow you to create a list of approved devices that can access the network, preventing unauthorized devices from connecting. This adds an extra layer of security beyond just a password.
Secondly, troubleshooting network issues often requires knowing the MAC address. Network administrators can use it to identify specific devices experiencing connectivity problems. If you’re having trouble connecting to a Wi-Fi network, providing your MAC address to the network administrator can help them diagnose the issue.
Thirdly, setting up parental controls frequently involves using MAC addresses. Routers often allow you to associate MAC addresses with specific profiles, enabling you to restrict internet access for certain devices at specific times. This is particularly useful for managing children’s screen time.
Finally, some public Wi-Fi networks require registration based on MAC address. This helps them track usage and prevent abuse. Understanding how to find your MAC address is essential for accessing these networks.
Finding Your MAC Address on Different Devices
The process of finding your MAC address varies depending on the device you’re using. Here’s a breakdown of how to find it on some of the most common devices:

The Command Prompt is a powerful tool that allows you to interact directly with your operating system. It’s a quick and reliable way to find your MAC address.
Open the Command Prompt by searching for “cmd” in the Windows search bar and pressing Enter. Once the Command Prompt window is open, type the command “ipconfig /all” (without the quotes) and press Enter.
This command will display a wealth of information about your network connections. Scroll down until you find the section related to your Wi-Fi adapter. Look for the line labeled “Physical Address.” The value next to this label is your MAC address. It will typically be displayed as a series of six pairs of hexadecimal numbers, separated by hyphens or colons (e.g., 00-1A-2B-3C-4D-5E).
Remember to look for the “Physical Address” specifically under the section related to your Wi-Fi adapter. If you have multiple network adapters (e.g., Ethernet and Wi-Fi), you’ll see multiple “Physical Address” entries.
Using Network Connections
You can also find your MAC address through the Network Connections settings.
First, open the Control Panel. You can do this by searching for “Control Panel” in the Windows search bar. In the Control Panel, navigate to “Network and Internet” and then “Network and Sharing Center.”
In the Network and Sharing Center, click on “Change adapter settings” on the left-hand side. This will display a list of your network adapters.
Right-click on your Wi-Fi adapter and select “Status.” In the Wi-Fi Status window, click on the “Details” button. This will open the Network Connection Details window, where you’ll find your MAC address listed as “Physical Address.”
Finding Your MAC Address on macOS
Finding your MAC address on a Mac is just as simple.
Using System Preferences
The easiest way to find your MAC address on a Mac is through the System Preferences.
Click on the Apple menu in the top-left corner of your screen and select “System Preferences.” In System Preferences, click on “Network.”

Using Wi-Fi Direct (Alternative Method)
Some Android devices also display the MAC address in the Wi-Fi Direct settings.
Go to Settings and then Wi-Fi. Tap on Wi-Fi Direct. The MAC address should be listed there, sometimes labeled as “Device Address”.
Finding Your MAC Address on iOS (iPhone/iPad)
Unfortunately, Apple has restricted direct access to the Wi-Fi MAC address on iOS devices for privacy reasons. Since iOS 14, iPhones and iPads use a private Wi-Fi address by default. This means that each time your device connects to a different Wi-Fi network, it uses a different MAC address.
Private Wi-Fi Address
The private Wi-Fi address feature is enabled by default to enhance privacy. You can disable it for specific networks, but you won’t find a global setting to disable it entirely.
To check if Private Wi-Fi Address is enabled for a particular network, go to Settings, then Wi-Fi. Tap on the “i” icon next to the network you are connected to. You’ll see a toggle for “Private Wi-Fi Address.” If it’s enabled, your device is using a randomized MAC address for that network.
Disabling Private Wi-Fi Address will reveal the actual MAC address of your device to that specific network. However, this address will likely be different from the one displayed on other devices. This is because iOS may still be using a randomized address internally.
Workarounds for Finding the Original MAC Address
While you can’t directly find the original MAC address on your iOS device, you might be able to find it through your router’s admin panel. When your iPhone or iPad connects to your Wi-Fi network, your router will record the MAC address it’s using. You can log in to your router’s admin panel (usually by typing its IP address into a web browser) and look for a list of connected devices. The MAC address associated with your iPhone or iPad will be displayed there. Keep in mind that this will be the randomized MAC address if Private Wi-Fi Address is enabled.
Finding Your MAC Address on Other Devices
The process for finding your MAC address on other devices, such as smart TVs, gaming consoles, and streaming devices, varies depending on the device’s operating system and interface. However, the general approach is similar: look for network settings or device information.
