Can I request a specific address number?

No, addressing allows for very little flexibility in the number issued because the way addressing works. Address numbers run sequentially along named roadway segments, on the left and right, at a ratio of 1000 digits per mile. These are called centerlines. Whether the left or right side of the centerline is assigned odd or even numbers depends on the roadway orientation. Generally, odds run along the north and west, evens run along the south and east. The appropriate address number for a structure is set by where the access (driveway) or the front door (invisible perpendicular line) intersects with the centerline, depending on the situation. So, a structure's address is determined by its position along the centerline; it's math.
