Giới Thiệu · USPS Address Informational Tool
USPS offers an online tool to Validate Address Information. However, it is up to the individual company to program and implement. All the work has been done in this DLL. Easily validate an address (street level), perform a city state lookup or a zip code lookup quickly and easily for your USPS shipments in an object oriented environment with this tool. See our home page for code examples and additional licensing information.
This tool is intended for use by programmers. We are not affiliated with USPS. Version 1.32 added additional functionality and relaxed registry permissions.
