We get a lot of requests to decipher serial numbers on saddles. So we've made a simple tool for you to look up your Circle Y serial number (above). Most Circle Y serial numbers are located on a silver plate or leather strap under the mounting side of your saddle.
Enter your serial # as one continuous number without dashes (ex. 1157860104)
In addition to the the serial number, a date code will be included on the plate, along with the long serial number, which will tell the year of manufacture and the unique number for that saddle (example 20090001- which is 2009 and 0001 the unique number for the saddle).
Seat Leather/Color Codes
This period of serial numbers are much like the above. Use the chart to determine tree sizes, seat sizes, and colors. There may be an extra number at the end (represented by CD). This just means that more than one of this type of saddle was made that day, so it got a unique number at the end.
These numbers vary greatly. The first three numbers could represent the style of the saddle. Beyond that, the number meanings are unclear.
