ROMs used by Sega have a unique part number that corresponds to the program (including revisions). The first part is a 3-letter identifier:

The next part is the number itself, ranging from 4 digits (Sega's earliest arcade games) and up.

The number is usually silkscreened onto the ROM package or printed on a label that is affixed to the ROM.

ROM types

A lot of Sega's ROM chips produced by Fujitsu are in a particular form, with a line along the long edge of the body and a large circular depression in the middle. These have a number which describes the ROM type:

83100028-pin PDIP128Kx8, no mapper
83100128-pin PDIP128Kx8
83201132-pin PDIP256Kx8, SRAM support
83400032-pin PDIP512Kx8, no mapper
834011 512Kx8
834200 ?Kx16 (?)
838200 ?Kx16 (?)

Sometimes the part number has an A suffix, though its meaning is not understood. Following the part number is a speed designation value, typically '-025' for 250ns.
