Where to find your iPhone's MAC Address

Your iPhone's MAC address (Media Access Control address) is a unique identifier that your home network uses to recognize your phone. Unlike your IP address, which can change, your MAC address stays the same. You find it in Settings under Wi-Fi, in a section called Wi-Fi Address.

Open Settings, tap Wi-Fi, then look for the network you are currently connected to. Tap the information icon (a small circle with an "i") next to your network name. Scroll down and you will see "Wi-Fi Address" — that 12-character string of letters and numbers is your MAC address. It looks like this: a4:b2:3c:d1:e5:f6.

If you need your MAC address for a device that is not yet connected to your network, you can also find it in Settings under General, then About. Scroll to the bottom and look for "Wi-Fi Address" there as well. Both locations show the same number.

Key Takeaways

  • Your iPhone's MAC address appears in Settings under Wi-Fi, next to your connected network name, labeled as Wi-Fi Address.
  • You can also find it in Settings under General, then About, scrolled to the bottom of the page.
  • The MAC address is a 12-character code made of letters and numbers, and it never changes on your phone.
  • Your router uses the MAC address to recognize your iPhone on the network, separate from the IP address your phone receives.

Why your router needs your MAC address

Your router keeps track of devices on your network using MAC addresses. When you connect your iPhone to Wi-Fi, the router assigns it an IP address — but the router remembers which device that IP address belongs to by storing the MAC address. This is how your router knows to send data to your phone and not to your laptop or smart speaker.

Some routers also use MAC addresses for a feature called MAC filtering, which means the router only allows devices with approved MAC addresses to connect. If your router has this turned on, you would need to add your iPhone's MAC address to an approved list before it can join the network. Most home routers do not use this feature by default, but some people turn it on as an extra security step.

When you need to write down your MAC address

You might need your iPhone's MAC address if you are setting up a new router, troubleshooting a connection problem, or registering your phone on a guest network. Some workplaces and schools also ask for MAC addresses before allowing a device on their network — this is how they control which devices can connect.

If you are setting up a new Wi-Fi network at home, you generally do not need to do anything with MAC addresses. But if your router has MAC filtering turned on, or if you are connecting to a network that requires device registration, having your MAC address written down saves you a trip back to Settings.

The difference between MAC address and IP address

Your iPhone has both a MAC address and an IP address, and they do different jobs. The MAC address is permanent — it is built into your phone's hardware and never changes. The IP address is temporary — your router assigns it when you connect, and it can change if you disconnect and reconnect, or if your router restarts.

Think of the MAC address as your phone's serial number and the IP address as your phone's mailing address on that specific network. The MAC address identifies what device you have. The IP address tells the router where to send data while you are connected. Your router uses the MAC address to decide which device gets which IP address.

What your MAC address reveals about privacy

Your MAC address is visible to any network you connect to, including coffee shops, airports, and libraries. The network operator can see it and log which devices connected and when. However, your MAC address does not reveal your identity by itself — it is just a number that identifies your phone on that specific network.

Some phones and operating systems let you randomize your MAC address when you connect to public networks, so the network sees a different number each time instead of your real one. iPhones running iOS 14.3 and later have a feature called Private Wi-Fi Address that does this automatically. You can check whether it is turned on by going to Settings, Wi-Fi, tapping the information icon next to your network, and looking for "Private Wi-Fi Address" — if it shows "On", your real MAC address is hidden from that network.

Copying and sharing your MAC address

Once you find your MAC address in Settings, you can tap and hold it to copy it, then paste it into an email or a form. Some routers have a setup page where you paste MAC addresses into an approved list. Some networks ask you to enter your MAC address on a registration page before you can connect.

When you share your MAC address with someone, you are not sharing anything that identifies you personally — it is just a device identifier. But only share it with networks or people you trust, because someone with your MAC address could potentially use MAC filtering to block your phone from a network, or use it to impersonate your device on a network they control.

Frequently Asked Questions

Is my MAC address the same on Wi-Fi and Bluetooth?

No. Your iPhone has a separate MAC address for Wi-Fi and a separate one for Bluetooth. The Wi-Fi Address in Settings is only for Wi-Fi networks. Bluetooth devices use a different identifier. If a device asks for your MAC address, ask whether they mean Wi-Fi or Bluetooth — usually they mean Wi-Fi.

Can I change my iPhone's MAC address?

You cannot permanently change your iPhone's MAC address — it is part of the hardware. However, iOS 14.3 and later can randomize it temporarily for each network using Private Wi-Fi Address. This is turned on by default for most networks, but you can turn it off per network in Wi-Fi settings if a network requires your real MAC address.

What if I see two different Wi-Fi Addresses in Settings?

You are probably looking at two different places — one in Wi-Fi settings and one in General, About. They should show the same number. If they do not, restart your phone and check again. If they still differ, contact Apple Support, because this usually means a hardware problem.

Do I need my MAC address to connect to my home Wi-Fi?

No. Most home routers do not use MAC filtering, so your iPhone connects automatically without needing to register your MAC address. You only need it if your router specifically asks for it, or if you are setting up a guest network with restrictions.
