depending on numbers on loop , have same long character

What i'm trying to do is this : write a script that's gonna increment numbers and write them in two different files Now these files are inputs for another command that , in order to consider a user valid, we mush have 24 characters in the ISE2 = 6000011914A0A2E60004DC6$i

But in my loop, when numbers are above 9 , it becomes more than 24 and the users are no longer eligibles; How can i fix that?

echo "exits"
else
