The concept for Serial Box began many years ago while trying to solve the problem of carrying around reference and serial number books when inspecting equipment. The team at Serial Box has worked over the course of the last year to compile and validate one of the largest collections of serial numbers in the world. At Serial Box, we believe the first step in buying construction equipment related to the construction industry, such as Caterpillar, Komatsu, John Deere and Bobcat is validating the machine’s serial number. Serial Box is your go-to Heavy Equipment Serial Number guide.
