It's easier for me to remember numbers, only on glance sometimes. Those who answered no, is it just because it's not important? Do you remember your bank accts?
I rarely use PIN-PIN messaging, and the only time I need to communicate my PIN is if I'm changing devices, for software licensing. So it wouldn't really be a benefit to remember it in my case.
