Address Verification is developed using the

C++

programming language. Address Verification provides different software packages to suit the hardware and software environment in which you want to install Address Verification. The Address Verification software packages contain C and Java based APIs.

You can install Address Verification on devices that run any of the following configurations:

Address Verification is designed to be highly efficient in its memory and resource usage. To ensure best possible performance, install Address Verification on a device that has fast input and output systems and sufficient memory.

The device on which you install Address Verification should have a minimum of 512 MB RAM.

Before you finalize the memory requirements, consider the size of the reference address databases that you require. The complete set of worldwide postal reference databases, including supplementary databases for address enrichments, consumes approximately 55 GB of storage space.

Preloading databases into memory significantly improves the performance of Address Verification. The device on which you install Address Verification must have sufficient RAM to preload the databases that you require.

As the total size of the worldwide databases is approximately 55 GB, the RAM required to preload all databases and perform address processing is approximately 60 GB. For smaller file sizes, less RAM is required. For example, the worldwide batch and interactive databases consume approximately 9 GB of space, and the geocoding databases consume an additional 11 GB. To preload and run the worldwide batch, interactive, and geocoding databases, 20 GB to 25 GB of RAM is necessary.

You set the database preloading method in the

SetConfig.xml

file. For more information on database preload settings, see the
