Most people I know have several bank account and credit card numbers memorized. It's the same for me, and I also remember my phone number from when I was 4; but not the area code!
I think there is a cultural bias in the U.S. against remembering numbers, but that people are generally able to do so. Memorization tends to happen naturally through use: it's easier for me to remember a bank account number after making deposits over a few months than by purposefully memorizing it, for instance.
