Yep, "serial number" was basically the argument for using a number type in the first place, and here they were sequential. Even then, ignoring the JSON peculia

Yep, "serial number" was basically the argument for using a number type in the first place, and here they were sequential. Even then, ignoring the JSON peculiarities, it would have been ok up till someone had the brilliant idea to have x digit serial numbers for one product line, and y digit for another. With only zero padding to tell them apart. This person, not a programmer, could not fathom why it caused the "tech heads to go crazy". Sometimes I debate collecting stories like this.
