Brother sewing machine serial numbers are coded to indicate the manufacture date of the machine. The letter and first number indicate the month and last digit of the year the machine was made. Because the first number in the serial number could correspond to a year in any decade, you need help from Brother International Corp., the machine's manufacturer, to determine when the machine was made. You can submit an e-mail request through the company's website.
Find both the model and serial numbers on your Brother sewing machine and write them down. The model and serial numbers are usually printed on a tag affixed to the back of the machine, but may be located elsewhere on the machine's exterior.
