Fender began producing instruments in its Ensenada, Mexico, factory in 1990.
Instruments made between 1990 and 2000 carry MN prefix serial numbers,
with the M designating Mexico and the N designating the 1990s.
The numbers for each year typically overlap, as there is always a transitional period between successive
years and as necks that are made and serial numbered late in any given year are used on instruments assembled in the early
months of the following year.

A new serial-numbering scheme was adopted toward the end of 2009 using the number 10 as a prefix,
followed by a space, followed by seven digits. The 10 prefix was designed to identify the first year of the second decade
of the new millennium, and while it appears on the instrument decals, it was not captured in Fenderâ€™s operating system.
Only the seven-digit suffixes were actually entered into the database. These serial numbers did not identify the country of
origin in the body of the number. Instead, the instrumentâ€™s country of origin appears on the decal on the back of the headstock,
near the serial number.
This new numbering scheme was short-lived and was replaced only a few months later by an improved scheme
that identifies an instrument's country of origin and year of manufacture in the body of the serial number.
This new scheme uses the letters MX as a prefix to designate an instrument made in Mexico,
followed by an eight-digit number. The first two digits of the number identify the year of manufacture,
(10 for 2010, 11 for 2011, etc.). The following six digits are the unit identifier, although it should be noted that
these final six numbers are not sequential and do not provide any other identification information about the instrument.
This new scheme is now used on the majority of Fender instruments made in Mexico, with certain exceptions.

EXCEPTIONS
The Jim Root Telecaster, James Burton Standard Telecaster, Buddy Guy Stratocaster (polka dot model),

The Reggie Hamilton and Frank Bello Jazz basses used an MX serial number prefix before the 2010 change.
California Series electric guitars and basses from 1997 and 1998 use an AMXN prefix and share U.S./Mexico origin.
