I must be wrong then, I thought a Z serial number was made in America.
My `08 Strat had a Z prefix and was made here so I`m a little confused at this point.
Z prefix serial numbers should be a USA-made "modern" models built in the 2000s (and as you know the first digit tells you the year). Fender added additional prefix letters for various series:
D for the American Deluxes (starting in 1998 when these came out) - so these serial numbers read "DN" for the 1998/99s and DZ for the 2000/2009s. There is an exception where some 2000 American Deluxes did not have the "D" prefix. S
S for the Artist Signatures starting in the late 1980s with "SE8" serial numbers (it took Fender up until about 1992/93 to use up the SE8 and SE9 decals and "catch up" to the year code).
M for the Made in Mexico models from their introduction until last year, so an "MN" would be an MIM in the 1990s; an "MZ" would be one made in the 2000s.
MS was used for MIM signature models like the Jimmie Vaughn guitars.
The new serial numbers really mess up these sites - all "modern" USA models used just a "10" from say January through about April, starting in May they began using a "US10" prefix. Also Fender has dropped the "D" and "S" additional prefixes.
As of about July of last year the MIM models now use an "MX10" serial number.
