What does an MN prefix mean on a Fender?

MN identifies Fender's Ensenada plant in Mexico during the 1990s. The digit after the letters gives the year within the decade, so MN5 is 1995–1996.

Are Mexican Fenders worse than American ones?

They are built to a different specification at a different price, in a Fender-owned plant under Fender's control. The difference is real but considerably smaller than the price gap implies, and country of origin is a poor proxy for how a particular instrument plays.

Fender Mexico serial prefixes and their production periods
Prefix	Years
MN0	1990–1991
MN1	1991–1992
MN2	1992–1993
MN3	1993–1994
MN4	1994–1995
MN5	1995–1996
MN6	1996–1997
MN7	1997–1998
MN8	1998–1999
MN9	1999–2000
MZ0	2000–2001
MZ1	2001–2002
MZ2	2002–2003
MZ3	2003–2004
MZ4	2004–2005
MZ5	2005–2006
MZ6	2006–2007
MZ7	2007–2008
MZ8	2008–2009
MZ9	2009–2010

From 2010 the format changed to MX followed by the two-digit year, e.g. MX17123456 for 2017.

Reading the number

MN covers the 1990s and MZ the 2000s, with the digit after the letters giving the year within the decade. MN5123456 is 1995–1996; MZ3123456 is 2003–2004.

From 2010 the pattern changed to MX plus the two-digit year, which dates the instrument to a single year rather than a range.

Examples

MN5123456 — 1995–1996
MZ3123456 — 2003–2004
MX17123456 — 2017

What Ensenada actually is

Ensenada is a Fender-owned plant in Baja California, not a contract factory. It opened in 1990 as production capacity was expanded, and it has built the Standard, Player, Vintera and Classic series among others.

It is worth being clear about this because “Made in Mexico” carries a reputation in the used market that the instruments do not always deserve. Ensenada builds to Fender's specification under Fender's control, and the gap between a Mexican and an American instrument of the same series is narrower than the price difference suggests.

The serial tells you where an instrument was built. It does not tell you how good it is, and treating country of origin as a proxy for quality will lead you past some very good guitars.
