Country codes

Country codification

For Williams/Bally
WPC-89, WPC-S and WPC-95.


Prior to 1990, Williams and Bally used a simple three-digit code to designate pinball models.

To differentiate the exported models from the US ones, an "I" (International) was added before the six-digit serial number that followed (the "proto / sample" models received an "X").

Example on a "Diner" (model 571):

From 1990 they started to use a five-digit coding by inserting two zeros after the first digit. This "00" was not really useful, except to differentiate the new models and the principle of the serial number remained unchanged.

Example on a "Fun House" (model 50003):

It was not until 1993 that this number was finally used, with the appearance of a bar code as well. The two-digit code corresponds to the configuration of the machine when it left the factory, which depends on on the one hand, the power supply used, and on the other hand, the coin mechanisms installed. These elements are specific to the country where the machine was sold.

Example on a "White Water" (model 5xx18):
