I don’t know if it has a base designation, but there is a way to represent natural numbers without 0. You just use 1, and numbers are distinguished by the number of 1s. So you’d count 1 11 111 1111 11111 and so on.
I think you’re thinking of the unary numeral system. While some people do call it “base 1”, it’s not really a positional number system like the other base N systems. In unary, you “write” 0 by just not writing anything.
