IBM Typewriter Serial Numbers

Also known as ElectromaticInternational (electric)Lexmark

Serial Number Table Last Edited: 07/1/17 09:59
NOTE: dates shown are JAN 1 unless noted, so the serial number shown is the *first* serial number produced the given year. Exceptions are serial numbers preceded by "up to"(where you can assume that the numbers reported in that subsection are DECEMBER 31, END OF YEAR NUMBERS) or rows where a month is given in the month column. If the serial number is shown as a range (xxxx-xxxx) it indicates that we know the entire range of serial numbers for the given year.

IBM       USA-Built and WT (World Trade) serial numbers followed different patterns.
Early USA-built Selectrics only have a 7-digit serial number (4000000 and up) without any other codes. Later machines have the product code (21, 26, 27 or 30) in front of the serial number. It seems that factory codes did not appear on Selectrics made in the USA until the Selectric III was introduced (around 1981).
 
        It seems MOST WT (World Trade) machines used the following numbering pattern:
XX - YY - ZZZZZZZ
Where XX is the Factory Code
Where YY is the Model Code
Where ZZZZZZZ is the Sequence Number
However, examples exist where the serial number follows pattern YY - XX - ZZZZZZZ
USA-made Selectric III's will usually follow the pattern YY - Machine ID Code - XX - ZZZZZZZ.
For Machine ID Codes, see table below.
