Fender squier serial number dating service
Stagemaster Deluxe (neck-thru maple necks with basswood wings), and the Double Fat Tele Deluxe (all solid mahogany with set necks), with serial numbers starting with KC for Korean Cort, followed by 2-digit year.
There were also some KV (Korean Saehan(Sunghan)) serial numbers followed by 2-digit year.
Neck-dating can be useful in determining the was produced, rather than the complete instrument.
Given the modular nature of Fender production techniques, an individual neck may have been produced in a given year, then stored for a period of time before being paired with a body to create a complete guitar, perhaps, for example, in the following year.
Korean Squiers: C refers to Cort, V refers to Saehan(Sunghan), S was already taken by Samick so Saehan(Sunghan) used V instead (Saehan(Sunghan) made the Vester guitars). The second character refers to the decade: N represents Nineties (1990's). So, for example "CN6" = made by Cort in 1996 and "VN6" = made by Saehan(Sunghan) in 1996.
Exceptions: Pro-Tone Series (solid ash bodies) had serial numbers with either a) no preceding letters and 7 digits, with the first number being the year, or b) starting with KC for Korean Cort, followed by 2-digit year.

Japanese Squiers: For Japanese serial number dating see Fenders site.USA Squiers: USA Squires are very rare and usually have a E serial number and were made for less than a year spanning 19.Six-digit serial numbers with no preceding letters, with the first number being the year. CY appears on most models produced in China, and is by far the most common form.Squier II's could not possibly have been assembled before 1987/88, as these represent the transition to Indian and then Korean production, and all the ramifications of such (the serial numbers can be off by years for these particular axes, and neck dates may also be misleading). This form is associated with Made in China Affinitys (with the standard body thickness of 45mm/1.75). These forms are apparently associated with the change to Crafted in China, so post-1996 models only would have this form of serial number. YN is associated with 'made in china' rather than 'crafted in china' and 1996 was the year they swapped to 'crafted in china' and mostly CY prefixes.
