<prompt> Human: Im moving in August, and the landlord of the apartment Ill be moving to wants checks for the security deposit and first months rent. The problem is that I dont have any checks. If I buy some, theyll have my current address, but I only need two. So Ill have an entire checkbook of checks with my old address once I move. Can these still be used or will I need to buy an entire new checkbook?  <response>: The address on a check is merely informational. It has zero impact on the validity of the check.You can get a cashiers check from your bank for your landlord.
