Find Pico MAC Address
Aug 2026
Introduction
When dealing with Wifi networks, or networks in general, especaially if your WIFI has MAC Address filtering enabled, you will need the MAC Address of your Pico(s).
A MAC Address is a 6 part address that looks like so:
- 88:a2:9e:01:49:57
The first three numbers are to identify the manufacturer, the last 3 numbers are for the ID of the device. In a layer 3 network (most networks now) we generally use the IP Address of the device, but in purely Layer 2 networks then the MAC addresses are used.
