Years of production and serial numbers for Underwood Typewriters

Important Note:

When use these lists, please considere these facts:

  1. I'm not an expert. I'm not able to clearly identify the models, or to provide other information if it doesn't appear in this site.
  2. Serial numbers for Underwoods are not so precises as you could expect. Several series of numbers could have been used at the same time. Various letters and numbers were used with serial numbers and I have no information on this. Lots of units were refurbished or reconditioned and original serial numbers could have been altered in this process. I have no information about other models than the ones that appear on this site.
  3. These serial numbers come from Underwood files, records kept by Remington Co., and Goverment Typewriter Catalogue (1.954)

So, if you can recognise your model and your serial number match with one of the following tables, you can date your Underwood precisely and with confidence. Otherwise I can provide you little additional help.

Any information you can provide will be wellcomed and included here.
