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.
A traditional Delivery Line 1 is comprised of a number of possible components, including:
Most of us are familiar with a structure’s primary number, street name, and street suffix. In a traditional Delivery Line 1, the primary number must always appear first. Each of these familiar components can be seen in the following address:
2 EASTWOODS RD SYOSSET NY 11791-2425
Delivery Line 1 can include some components that may be unfamiliar, however. Secondary designators (Ste, Apt, Bldg, PH, TRLR, HNGR, etc.) and secondary numbers (2, A, 2A, 101C, 203D, etc.) describe locations within a complex or building. These components can be seen in the following address:
232 WILLOW AVE APT 2L HOBOKEN NJ 07030-3645
In this example, Apt is the secondary designator and 2L is the secondary number.
Extra secondary designators and extra secondary numbers are similar, but describe the location of a building within a campus. These components can be seen in the following address:
5619 LOOP 1604 STE 101 BLDG E-5 SAN ANTONIO TX 78253-5795
In this example, Bldg is the extra secondary designator and E-5 is the extra secondary number.
A street predirection provides directional information before a street name, while a street postdirection provides directional information after a street name. These components can be seen in the following address:
1145 W GATEWAY CIR S APT 26A FARGO ND 58103-3552
In this example, W is the predirection and S is the postdirection.
Finally, Delivery Line 1 can include Private Mail Box (PMB) designators and PMB numbers. These components can be seen in the following address:
5546 SCRANTON RD APT A1 PMB 9571 HAMBURG NY 14075-3769
In this example, PMB is the PMB designator and 9571 is the PMB number.
A non-traditional Delivery Line 1 is comprised of slightly different components, including:
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.
The primary number of a non-traditional Delivery Line 1 looks like and serves the same purpose as in a traditional Delivery Line 1. The following example shows a non-traditional street name component followed by a primary number:
PO BOX 4735 TULSA, OK 74159-0735
That should be enough to get you rolling.
