Hmm, looks like quite easy.

For each digit, we have 26 letters + 10 numbers = 36 possibilities. There are 7 digits. So, total number of codes is 36*36*36*36*36*36*36 = 36^7.

I think that was an irony. But don't laugh at me.
I usually make mistakes in such questions In fact every time I see a probability/combinations problems, I'm dead.

I get E, $$36^7$$ too, but i'm kind of surprised the answer wasn't $$6^{14}$$ since 36 is a perfect square of 6.

I guess that depends on $$36^7$$ being the correct answer.
