What Is a MAC Address?
A MAC (Media Access Control) address is a unique 48-bit identifier assigned to every network interface. It's written as six pairs of hexadecimal digits (e.g. AA:BB:CC:DD:EE:FF). The first three octets (OUI — Organizationally Unique Identifier) identify the manufacturer, while the last three are assigned by the manufacturer to each device.

FAQ
Can a MAC address reveal my location?
No. Unlike IP addresses, MAC addresses operate at the local network layer and are not transmitted across the internet. They cannot be used to determine your geographic location.
Can I change my MAC address?
Yes. Most operating systems allow you to spoof (change) your MAC address. This is sometimes done for privacy on public Wi-Fi networks. Modern iOS and Android devices randomize MAC addresses by default.
Protect Your Device Identity
While MAC addresses stay local, your IP is exposed everywhere. NordVPN hides your real IP and encrypts your traffic on any network — especially public Wi-Fi.
