Does my Wi-Fi MAC address change periodically?

I am curious if my Wi-Fi MAC Address changes each time or periodically as I re-connect to the same network multiple times. For instance, when I connect to my home wifi network, will my Wi-Fi MAC address always be the same for that specific network, or will it change periodically/every time I establish a new session?

iPhone 14 Pro Max, iOS 18

Whether or not your MAC Address will change will be determined by your WiFi settings:

Settings > WiFi > [Your WiFI Network Name / SSID] - tap the blue "i" icon - Private WiFi Address > select OFF, Fixed or Rotating as required


  • OFF - Your iPhone will use its unique burned-in MAC Address that was assigned during manufacture.
  • Fixed - Your iPhone will use a randomly selected MAC Address; this MAC Address will always be used for this WiFi connection.
  • Rotating - Your iPhone will use a randomly selected MAC Address; this MAC Address will change periodically, or when reconnecting to this WiFi network connection.


Be aware that the Private Address feature is largely unnecessary for your home WiFi network; if enabled, Private Addressing can cause issues if specific MAC addresses are expected by your WiFi Router. You may need to disable this feature - and can be enabled or disabled for each individual network.
