Perfect Address Software Developer's Kit - Programmer Information

The SDK contains:

• A 32-bit Windows DLL for access to the database via C or similar languages
• Programmer's Guide
• Several sample programs written in Microsoft C++ and Visual Basic
• A header file for use with C compilers
• One current national address database CD-ROM

If the city and state are missing from the address, the DLL can usually match an address even if provided only an incorrect 5-digit ZIP code (within certain limits, of course).


Street Address
The DLL employs advanced parsing and soundex routines to analyze, correct, and standardize street addresses. It finds and corrects misspelled street names, missing and/or misspelled street suffixes and missing pre and post directionals. It checks for known alias street names, correcting the address to the preferred street name. It detects and corrects numeric street names which are spelled out (tenth for 10th), as well as fully spelled directionals (EAST for E) and suffixes (DRIVE for DR).

The parsing routines cleanly combine or separate misused street name elements (BROAD WAY for BROADWAY, or SOUTHWESTERN AVE for S WESTERN AVE). The DLL accepts many forms of secondary addresses, including # (as in 425 Medical Dr # 118), correcting to the secondary type appropriate for that address (APT, STE, etc.). It recognizes many corrupted forms of PO Box, Rural Route, Highway Contract, and General Delivery. The DLL even recognizes the Spanish form of many addresses!


ZIP+4, Congressional District, Delivery Point Bar Code, County Name and County FIPS Code, Area Code, Time Zone and Daylight Saving Time Flag
Having matched and standardized an address, the DLL also provides the ZIP+4, congressional district, delivery point (POSTNET) bar code, county name and county FIPS code, area code, time zone, and daylight saving time flag for that address.


ZIP Code and ZIP+4 Lookup
The DLL provides two special "reverse search" functions which are used to find the city and state or full address associated with a ZIP code. If you call the DLL with a 5-digit ZIP code, it returns the preferred city name and state for that ZIP code. If you call the DLL with a full ZIP+4, it returns the address or address range to which that ZIP+4 applies.


Address Lookup Functions
The address lookup functions provided by the Windows DLL fall into two types:

1. Handle-based, where the calling task identifies itself via a unique handle assigned by the DLL, and parameters are passed individually, primarily as string pointers. These functions are provided for those situations where the DLL is called from a production application program, such as Visual Basic or WordPerfect, which cannot directly address the parameter block allocated for the task by the DLL. The handle identifies an internal parameter block maintained for the calling task by the DLL.

2. Parameter-block, where the calling task identifies itself via a pointer to a parameter block allocated by the DLL, and all parameters are passed in the parameter block. These functions are used provided for those situations where the DLL is called from a custom application program which can directly address the parameter block and its string variables. Such applications are usually written in C or C++.
