The Internet Pinball Serial Number Database or IPSND collects serial numbers of pinball machines and publishes a database of these on the Internet. Our goal is to make available a registration of all pinball machines in existence and allow tools for slicing, dicing and visualization of the data.

Locating Serial Numbers on a Pinball Machine:

Finding serial numbers on a game can sometimes be quite challenging. They are commonly hidden, painted over, destroyed or just in non-obvious places. The main difficulty is that manufacturers put their serial numbers in a variety of places in and out of the game and then they often changed the location of the serial number as time went on. Several manufacturers used a consistent numbering system for many years and others changed their formats often. In addition, there are frequently numbers on a game that might not be the serial number at all, it could be a part number, an inspector number or something that has no connection to the actual serial number at all.

This page is a reference on how to locate serial numbers for all manufacturers in the database. The nice part is that you can add your own tips and suggestions for other people to read as well. I have added initial comments on the information that I have from Bill Ung out of the original Internet Pinball Project (now defunct). Feel free to submit new information on serial number locations specific to each manufacturer and appropriate time period.

It seems that serial numbers are stamped into the side of the cabinet directly below the right flipper button.

Or under the coin door, or sometimes on the back of the machine.

For all Atari pinball there should be an info sticker on the back of the machine. If this is too damaged to read, then look at the main board. Atarians will have a four digit number near the MPU. (eg. 0214). Time 2000 will have a GS followed be four digits (eg. GS2468). Airborne Avenger will have a six digit number stamped into the right side under the flipper button starting with a 13 (eg. 132567) Middle Earth and Spaceriders 6 digit number will be under the coin door. Middle Earth starts with a 24 and Space Riders with a 25.

The Superman machine has it stamped into the cabinet below the coin mech door - 26xxxx
