Yes, the Amazon Smart Plug has a MAC address, and you can find it in the Alexa app

Every Amazon Smart Plug comes with a MAC address — a unique identifier that your network uses to recognize the device. You'll need this address if your router requires you to manually register devices, if you're setting up network security rules, or if you're troubleshooting connection problems.

The easiest way to find it is through the Alexa app on your phone. Open the app, go to Devices, select your Smart Plug, tap the settings gear icon, and scroll down to "About" or "Device Information." The MAC address appears there as a string of six pairs of letters and numbers, like AA:BB:CC:DD:EE:FF.

If you can't access the app, you can also find the MAC address on your router's connected devices list. Log into your router's admin panel (usually at 192.168.1.1 or 192.168.0.1), look for a section called "Connected Devices," "DHCP Clients," or "Device List," and search for "Amazon" or "Plug." The MAC address will be listed next to it.

Key Takeaways

  • The Amazon Smart Plug's MAC address appears in the Alexa app under Device Information or About settings.
  • You can also find the MAC address by logging into your router and viewing the list of connected devices.
  • The MAC address is formatted as six pairs of characters separated by colons, like AA:BB:CC:DD:EE:FF.
  • You'll need the MAC address if your router uses MAC filtering, if you're setting bandwidth limits, or if you're troubleshooting network issues.
  • The MAC address does not change unless you factory reset the device or change its network connection method.

Where to find the MAC address in the Alexa app

Open the Alexa app and tap the Devices tab at the bottom of the screen. Select "Plugs" or "All Devices," then tap the specific Smart Plug you want to check. Tap the settings icon (usually a gear) in the top right corner of the device card.

Scroll down until you see a section labeled "About," "Device Information," or "More Details." The MAC address will be listed there, sometimes labeled as "MAC Address," "Hardware Address," or "Wi-Fi MAC." It's a 48-bit address shown as six pairs of hexadecimal characters.

Write down the MAC address or take a screenshot — you'll want to keep it handy if you need to reference it later for router settings or network troubleshooting.

Finding the MAC address through your router

If the Alexa app isn't working or you prefer to check your router directly, log into your router's admin panel. Open a web browser and type your router's IP address into the address bar. Common addresses are 192.168.1.1, 192.168.0.1, or 10.0.0.1. You'll be prompted to enter your router's username and password.

Once logged in, look for a menu option called "Connected Devices," "DHCP Clients," "Device List," "LAN Devices," or "Attached Devices." The exact name depends on your router brand and model. Search the list for "Amazon" or look for a device named something like "Amazon-Plug" or "Alexa-Device."

The MAC address will be displayed next to the device name. If you see multiple Amazon devices, match the name or IP address to the specific plug you're looking for. Some routers also let you click on the device to see more details, including the MAC address in a different format.

What the MAC address format looks like

A MAC address is always 48 bits long and is written as six pairs of hexadecimal characters (0–9 and A–F) separated by colons or hyphens. An Amazon Smart Plug's MAC address might look like 50:F5:DA:12:AB:CD or 50-F5-DA-12-AB-CD. Both formats are the same address — the separator style just depends on where you're viewing it.

The first three pairs (called the Organizationally Unique Identifier, or OUI) identify the manufacturer. Amazon's Smart Plugs typically start with 50:F5:DA or similar prefixes. The last three pairs are unique to your individual device, so no two Smart Plugs will have the same complete MAC address.

When you enter a MAC address into your router or another device, make sure you use the exact format that device expects — some systems want colons, others want hyphens, and some want no separators at all. If you're copying and pasting, the system usually handles the conversion automatically.

Why you might need the MAC address

The most common reason to find your Smart Plug's MAC address is MAC filtering — a security feature where your router only allows specific devices to connect. If your router has MAC filtering enabled, you'll need to add the Smart Plug's address to an approved list before it can join your network.

You might also need the MAC address if you're setting up bandwidth limits or quality-of-service (QoS) rules on your router. These features let you prioritize or restrict network speed for specific devices. Some routers require the MAC address to identify which device the rule applies to.

If your Smart Plug keeps disconnecting or won't connect at all, your router's support team might ask for the MAC address to help troubleshoot. It's also useful if you're resetting your network and want to make sure the plug reconnects to the same device name and settings.

What happens if you factory reset the Smart Plug

Factory resetting an Amazon Smart Plug does not change its MAC address. The MAC address is burned into the device's hardware when it's manufactured and stays the same throughout the device's life, regardless of how many times you reset it or change its network settings.

However, if you reset the plug, you'll need to set it up again in the Alexa app as if it were new. The device will reconnect to your network with the same MAC address, but you may need to re-add it to any MAC filtering lists or QoS rules you had configured.

Frequently Asked Questions

Can I change the MAC address of my Amazon Smart Plug?

No, the MAC address is a hardware identifier that cannot be changed. It's permanently assigned to the device during manufacturing. If you need a different MAC address for network purposes, you would need to replace the device with a new one.

Is the MAC address the same as the device name in Alexa?

No, they're different. The device name (like "Living Room Plug") is what you call it in the Alexa app and is changeable anytime. The MAC address is a hardware identifier used by your network and cannot be changed. Both identify the device, but in different ways.

Do I need the MAC address to use the Smart Plug normally?

No, the MAC address is only needed for specific network configuration tasks like MAC filtering, QoS rules, or troubleshooting. For everyday use — turning the plug on and off through Alexa — you don't need to know or use the MAC address at all.

What if I can't find the MAC address in the Alexa app?

Make sure you're looking at the right device and that the plug is connected to your network. If the app doesn't show the MAC address, try logging into your router instead. Every connected device's MAC address appears in the router's device list, even if the Alexa app doesn't display it clearly.

Can two Smart Plugs have the same MAC address?

No, every device has a unique MAC address. If you own multiple Amazon Smart Plugs, each one will have a different MAC address. This is how your router tells them apart on the network.
