Pioneer Manufacturing Date Codes
Pioneer Version Codes

Find the date (month and year) your Pioneer audio equipment was manufactured. This is NOT a chart of when the Pioneer Units were "sold." Depending on many factors, the unit may have been first sold at retail many months or possibly years after it was manufactured.

Use this chart to figure out the date you Pioneer audio equipment was manufactured. The Serial Number on the back of your unit has two letters at the beginning. The FIRST LETTER = the YEAR it was manufactured and the SECOND LETTER = the MONTH of that year.

Pioneer started the alphabet over again starting in 1980 and presumably will do the same in 2006.
