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.

You may enter your website here. There will be a link to this site from your submission details.

Your Website:

Enter the country that the game is currently in. Please do not enter your country if the game is located in a different country. We are trying to track serial trends and where games were shipped from the distributor.


Enter the serial number of your game here. Be sure to verify your serial in multiple places on the game if possible as it can be difficult to read serial numbers especially when they are stamped into the wood.

Serial Number:
Note: Spaces and dashes are removed automatically

Some games have a serial number that is formatted specifically for that game, it may have a special prefix/suffix or have special characters in the middle of the number. Be sure to enter your serial number in the format examples as shown otherwise the site will not accept your submission.


It is often the case that game serials can be registered by non-owners when a game is at a show etc. We want to be able to distinguish ownership if possible.

Owner Status:


It is important for us to distinguish between serial numbers tha have been submitted by physically reading them off a game vs. serial submissions that come from other sources such as owner's list, auctions, RPG posts or other sources. The value of these other sources is still there but they inherently have a little less value simply because there is more chance of error since the submitter is not looking at the actual machine.

Collection Method:


Specify if the serial number you are registering is for a complete games, just the backbox or just the cabinet. You may also specify that the serial number you are submitting is for a game part such as a CPU, Driver or other PCB. It is common for games to have PCB's from other games due to repairs etc. These are still valuable to us as they verify the existence of serial numbers. If you submit a game part serial number under a specific game, that serial will not be directly linked to that game but will be put into the database as a stand alone serial number.

Game Part:
(What Happened to Game Parts?)  

It is common for games to have a datestamp somewhere on them, it is often stamped on the edge of the playfield plywood on the front edge. It is occaisionaly on the side edge. It is also common for games not to have this date anywhere on the cabinet. Please only submit dates that are on the game itself, not from other sources.

Date Stamps:

Specify if the game or part is complete, only of value as parts or unknown to you.

Game Condition:

You may add any additional comments about your submission here. If there is something special you know about the game (known prototype, oddities, artwork differences, etc) please enter it here.



You can now specify a physical location of the game with the registered serial number, this allows us to over time track and map games around the world!!

Game Traits are properties that you or anyone else can add to a game in the IPSND. There are instances where a particular game model may have features, printing differences or other properties that changed through the production run of the game. It is often interesting to find trends about these features and collect info on what exact serial number range that feature existed on. An example is Williams 1981 game Jungle Lord which had two different cabinet colors, red and blue.

Game Traits: (Submit your own custom Fields)

Backglass 'Added Balls' Feature - Typical games had a normal credit display in the center of the backglass. There exist some games that have a larger score reel in place of the credit display and the backglass has a label saying 'Added Balls' under the reel.

Lower Playfield Artwork - Early Production games had their lower playfield artwork filled with musical instruments, as in the flyer. During production, the artwork was changed to remove all of the musical instruments in the lower playfield, leaving a large expanse of blue paint in this area.
