The first 6 digits are the manufacturer and the next 5 digits identify the product. The error has been corrected in the examples. Thanks to bobskinner and others for visiting the site. I hope your students are enjoying the math of NUMBERS...Kathy E Thanks to bobskinner for catching that error. The first 6 digits are the manufacturer and the next 5 digits identify the product.

Could you help us out as to which one is the correct version? This seems like an excellent real life task for students who otherwise might find math less than interesting.
