National ZIP+4 Address Database Information Source
The National ZIP+4 Address Database is published by CD Light, LLC, a company which holds a non-exclusive license from the United States Postal Service to publish and sell the National ZIP+4 Address Database. The content of these files comes directly from the United States Postal Service, which is solely responsible for the accuracy of the information contained therein.
National ZIP+4 Address Database Contents
The National ZIP+4 Address Database consists of 929 separate files, organized by 3-digit ZIP code, on a single CD-ROM. Each file contains a variable number of fixed-field-length ASCII ZIP+4 (9-digit ZIP code) address records of 182 bytes each, with no record delimiter (no carriage return nor line feed characters). Within a given file, the records are sorted by 5-digit ZIP code. Each file is then compressed using PKZIP V2.04g.
This database also includes the US Postal Service city-state file, which contains a complete listing of the approximately 42,700 5-digit ZIP codes currently assigned by the USPS. This file has approximately 71,500 fixed-field-length ASCII records of 129 bytes each. This file is also compressed using PKZIP V2.04g.

Documentation
In addition to the ASCII text documents from the US Postal Service which accompany the ZIP+4 address files, the National ZIP+4 Address Database also includes a copy of the USPS's Address Information Products Technical Guide in Adobe Acrobat format. This document provides much more detailed formatting and usage information for the ZIP+4 address files and the city-state file, among others.
Address Ranges
The USPS claims that privacy laws passed by Congress prohibit it from making available an exact street address database. Like all other databases based on the USPS ZIP+4 address database, the National ZIP+4 Address Database does not actually contain every street number to which mail can be delivered. Instead, the database contains a total of about 30 million records, many of which define address ranges, especially in residential areas.
An address range record defines the lowest and highest street numbers which can exist for a given "block face" as well as the ZIP+4, carrier route number, and county name which apply to all addresses which may actually exist on that block face. In many cases exact street numbers are not actually defined in the database. This, by the way, is exactly the case for all commercial products based on the USPS ZIP+4 address database.
Matching the ZIP+4 Records to the City-State File
If you wish to identify the city name to which a particular ZIP+4 address record belongs, you should use the ZIP+4 "city-state key" field. This 6-character alphanumeric field identifies a unique record with that same key in the city-state file, which contains the city name preferred by the US Postal Service for mail delivered to that particular address or address range.
CAUTION - THIS DATABASE IS VERY LARGE AND NOT EASY TO USE. IT IS BEST SUITED FOR EXPERIENCED SOFTWARE DEVELOPERS ONLY!
