Part numbers

For decades Sega has maintained a list of part numbers for physical products it has created, ranging from game disc and box labels, to screw sizes and electronic components. Everything that makes up a Sega product usually has an internal part number, designed exclusively for Sega.

Sega part numbers typically take the form of a three-part code separated by hypens:

XXX-YY..YY-ZZ

In this example, the X section represents a three character code depicting the type of part. The Y section, initially 4 but now often six (or more) characters in length, is an exclusive code to the specific part. The Z section is an optional region code or revision. Initially codes were constructed entirely out of digits between 0 and 9, though it is more common in newer arcade machines to see letters, often to give clues for game-specific parts.

Not all parts of a Sega product conform to this standard, particularly those sourced from outside of the company.
