The numbers start with the year and are sequential after that, resetting each year. So your number, 2017171** is the 17,1** submission of 2017. There were a lot of 10 digit numbers (i.e., hundreds of thousands of submissions) last year because so many people were trying to avoid 41F (the rules requiring photos/fingerprints that killed e-filing).
