If your product came in plastic packaging (a clamshell), you’ll find the model number on the front of the insert card, on the lower left corner. If your product came in a box, you’ll find the model number on the top of the box.
Most model numbers are 12-16 characters and start with a couple letters followed by a dash.
No packaging? No problem!
The product number is on a label on the side of the dimmer or switch.*
If you’ve already installed the dimmer/switch, turn off the electricity and then remove the wallplate. Unscrew and remove the wallplate adapter, then unscrew the dimmer/switch and pull it out of the wall until you can see the label.
*Please note: The product number for Ariadni/Toggler dimmers is not on a label. It’s located directly on the front of the dimmer on the top left, or right below the on/off toggle.
