23 Delivery Address Line

231 Components

The Delivery Address Line, as matched against the ZIP+4 file, must be broken down into its individual components on the mailpiece with one space between address elements.

These components are the primary address number, predirectional, street name, suffix, postdirectional, secondary address indentifier, and secondary address.

The Postal Service uses the parsing logic below to enter address information into the files. When parsing the Delivery Address Line into the individual components, start from the right–most element of the address and work toward the left. Place each element in the appropriate field until all address components are isolated. This process facilitates matching files with AIS products and produces the correct format for output to a mailpiece.

Note: Mailers may use any parsing logic to achieve the same result.
