Taiwan Serial Numbers (1971 to 1981+)
Yamaha changed the Taiwan serial number system 4 times between 1971 and 1979:
• They started in June 1971 with a 7 digit serial number (sequential, not related to a date), prefixed with a “T”, stamped on the neck block. I assume they started with T0000001.
• In May 1972 they added an 8 digit serial number on the brace under the fretboard. YMMDDUUU, the same as the Japan made guitars, except these guitars have TWO sets of serial numbers.
• In the beginning of June 1973 they removed the “T” prefix from the lower serial number. They still have 2 sets of serial numbers.
• In May 1979 the stopped stamping the lower serial number. So, now they only have the 8 digit serial number on the brace under the fretboard, like the guitars exported from Japan.
• As typical for Yamaha, there are a few oddball serial numbers. I have some serial numbers in June 1976 thru September 1976 that have an extra “0” on the front of the 7 digit lower serial number, so they have 8 digits, starting with “00”.
• AND, although this is outside my scope of 1966 to 1981, it seems ALL guitars made in 1982 have 9 digits, adding a fourth Unit digit. YMMDDUUUU.
