You have four digits, each of which could be any of ten possible numbers, so the total number of possibilities is 10 x 10 x 10 x 10 = 10,000. However, since De Witt actually has two prefixes, (563) 659 and 221, it could have as many as 20,000 phone numbers. Of course, 221 numbers can only start with 221-1, 221-8, or 221-9, so it's really only 13,000 possible numbers.
