It depends on the coords of your village. The first number of the Y coordinate (xxx|yyy) is your first digit, with the second one coming from the first number of the x coordinate (xxx|yyy)
For example: 300|450 = k43
53|301 = k30 (the first digit would be 0, as there is only 2 numbers shown)
732|53 = k7 (first digit of y coord is 0)
