The serial number can now be found on all boxes on the base, inside the box at the rear of the driver’s side. The only exception is the RocketBox Pro 12.
On the RocketBox 12 you can find the serial number printed on the bottom of the box, near the mid-section, on the driver’s side.
In the example below the first 7 digits are the part number or SKU, and the last 4 digits are the serial number for the box.
On older boxes the Serial number was on a white sticker typically located on the inside of the box lid, but could also sometimes be found on the inside of box base.
