I was wondering about that actually. The first 5 characters of my wife’s drivers license now match the first 5 characters of my own after she changed her last name. (NJ drivers license and the numbers are a bit longer than the ones in MA)

Here's a site that shows the algorithm for FL, WI, and IL. It claims that MA uses the SSN, but I don't think that's the case, as you've noticed the number wouldn't change with a name change if it was based on SSN. Shortly before I moved back here ~5 years ago, I checked this algorithm against my FL license number and it was accurate, fwiw.
