This number is given to you when you are looking in the paper for a new place. You are offered to buy a list of homes in the are that you live in. You are also told that if you do not find a place in 90 days your money will be refunded to you. My 90 days have been up since april of this year and they still do not want to refund my money. There are alot of companies that sell the list make sure if you buy a list it is a good company, not all of them try to take people for their money.
