How can I find out when my Mexican-made instrument was manufactured? How can I find out how old my instrument is?

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.

SERIAL NUMBERS | PRODUCTION DATES |

MN0 + 5 or 6 digits |
1990-1991 |

MN1 + 5 or 6 digits | 1991-1992 |

MN2 + 5 or 6 digits | 1992-1993 |

MN3 + 5 or 6 digits | 1993-1994 |

MN4 + 5 or 6 digits | 1994-1995 |

MN5 + 5 or 6 digits | 1995-1996 |

MN6 + 5 or 6 digits | 1996-1997 |

MN7 + 5 or 6 digits | 1997-1998 |

MN8 + 5 or 6 digits | 1998-1999 |

MN9 + 5 or 6 digits | 1999-2000 |

At the end of 1999, the serial numbers transitioned from an “MN” prefix to an “MZ” prefix with the “M” designating Mexico and the “Z” designating the 2000s.

SERIAL NUMBERS | PRODUCTION DATES |

MZ0 + 5 or 6 digits |
2000-2001 |

MZ1 + 5 or 6 digits | 2001-2002 |

MZ2 + 5 or 6 digits | 2002-2003 |

MZ3 + 5 or 6 digits | 2003-2004 |

MZ4 + 5 or 6 digits | 2004-2005 |

MZ5 + 5 or 6 digits | 2005-2006 |

MZ6 + 5 or 6 digits | 2006-2007 |

MZ7 + 5 or 6 digits | 2007-2008 |

MZ8 + 5 or 6 digits | 2008-2009 |

MZ9 + 5 or 6 digits | 2009-2010 |

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 Fender’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 instrument’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.

The Jim Root Telecaster, James Burton Standard Telecaster, Buddy Guy Stratocaster (polka dot model), Robert Cray Stratocaster and Jimmie Vaughan Stratocaster use an “MSN” serial number prefix.

The Ritchie Blackmore Stratocaster and Duff McKagan P Bass use an “MSZ” serial number prefix.

The Reggie Hamilton and Frank Bello Jazz basses used an “MX” serial number prefix

California Series electric guitars and basses from 1997 and 1998 use an “AMXN” prefix and share U.S./Mexico origin.
