An iPhone's hardware Wi-Fi MAC address is labeled Wi-Fi Address in Settings. The address a particular Wi-Fi network sees may be different because iPhone can use a private Wi-Fi address for that network. Check which one you need before copying an address to a router, school, or workplace administrator.
Find the hardware Wi-Fi address
- Open Settings.
- Tap General, then About.
- Scroll to Wi-Fi Address. The colon-separated letters and numbers are the iPhone's hardware Wi-Fi address.
- Touch and hold the value if you want to copy it, or carefully transcribe it.
The Bluetooth address is a different identifier. Do not send that value when someone has asked for the Wi-Fi MAC address. If you manage several devices, check the device name at the top of About before recording the number.
Find the address used for a specific network
Open Settings > Wi-Fi, then tap the information button next to the connected network. Look for Wi-Fi Address and the Private Wi-Fi Address control. When the private-address feature is enabled, the network-specific value can differ from the hardware value in About. The network settings page is therefore the better place to look when an administrator is trying to identify the address currently seen by that network.
On iOS 18 and later, Apple lists Off, Fixed, and Rotating private-address options. Fixed uses a private address that stays the same for that network; Rotating periodically changes it. The choices shown can depend on the network's security and your iOS version. If a network access list uses an address, ask its administrator which value to register. Turning private addresses off reduces a privacy protection, so make that change only when the network requires it and you understand the tradeoff.
When an address does not match
First verify that you are looking at the correct Wi-Fi network, particularly if multiple networks have similar names. Then compare the value under the network's information page with the value in General > About. Private addressing is the usual reason they differ. If you recently reset network settings or changed the private-address mode, a network may see a new address; update its device registration if necessary. A cellular identifier, IP address, and Wi-Fi MAC address solve different problems and should not be substituted for one another.
Which Wi-Fi address should you give someone?
If an administrator is trying to identify the iPhone on a particular network, use that network's information page under Settings > Wi-Fi. If a form specifically asks for the hardware or built-in Wi-Fi address, use Settings > General > About > Wi-Fi Address. The values can be different when Private Wi-Fi Address is enabled. A router access list that expects the current network address may reject a hardware address copied from About.
Apple offers Off, Fixed, and Rotating choices for private addresses on supported iOS versions. Off uses the hardware address; Fixed uses a private address that stays the same for that network; Rotating changes it periodically. A network administrator may prefer a stable value for registration, but turning the feature off reduces the privacy protection it provides. Ask which address the network needs before changing a setting. A public or shared Wi-Fi network generally does not need your hardware address merely to let you browse.
Check and copy the value accurately
A Wi-Fi MAC address is a series of letters and numbers separated into pairs. Read the label carefully because Bluetooth Address, IP Address, and Wi-Fi Address appear in different settings and are not interchangeable. If you can copy the value, paste it into a secure message to the administrator instead of retyping; a single wrong character can prevent registration. Before sending it, confirm that you are on the intended network and that the request is legitimate.
When a registered iPhone still will not join
Check whether the network is seeing a private address different from the one you registered. Confirm the network name, then revisit its Wi-Fi details. If the administrator uses an allowlist, register the value currently shown for that network. A changed private-address mode or a reset of network settings can lead the network to see a new address. Also check that the Wi-Fi password and network service are working; an address mismatch is only one possible cause of a failed connection. If the password is rejected, follow the steps to forget the network and enter the correct Wi-Fi password.
Is the Wi-Fi address the same as the phone's serial number? No. The serial number identifies the device for support and ownership tasks; the Wi-Fi address identifies a network interface. Neither one tells you the country the phone came from; our guide to where iPhones are made explains how to check that.
Does every network see the hardware address? Not when private addressing is active. Apple designed private Wi-Fi addresses to reduce tracking across networks, so check the network's details for the value that network uses.
