 Shit. I was not paying attention to the five groups.

And why should you?

For some reason 3+8+8+1+1 = 21, is that mapping to an alphabet?

No doubt it could be made to be if one were determined enough... but no, I was just trying to make it easier on the eye than a great wodge of digits, and there is no need to read anything more into it than that.
I will be posting a (very small) hint tomorrow.
