So, you want to string together your own DeliveryLine1?
The second line of a US address is generally well understood: city, state, and ZIP Code. However, the first line can be trickier because there are a lot of possible address components that we don't see very often. In this article, we will show you how to assemble the various components that you might see in Delivery Line 1, including a discussion of the two types of Delivery Line 1: traditional and non-traditional.
In this example, Apt is the secondary designator and 2L is the secondary number.
In this example, Bldg is the extra secondary designator and E-5 is the extra secondary number.
In this example, W is the predirection and S is the postdirection.
In this example, PMB is the PMB designator and 9571 is the PMB number.
Unlike a traditional Delivery Line 1, the street name component always comes before the primary number. If the first word of the address is in the following collection, use a non-traditional Delivery Line 1. Otherwise, use a traditional formulation.
That should be enough to get you rolling.
