Address Standardization/Correction/Geocoding

Question

My place of employment is looking into buying a third party tool, for batch based US and Canadian Address correction, with Geo-coding.

• What Products have you used?
• What do you like about them?
• What do you not like about them?

Note that, We are a C/C++ Unix Shop.

Answer 1

We use Melissa Data, they have a number of solutions including geocoding and address normalization. They have good APIs and the support has been great. Their solutions work on many platforms and languages including C and C++ on Unix. Can't think anything negative about them.

Answer 2

We use Trillium in our office. They provide C# libraries that you can incorporate into your projects. It will take an address and return a pretty complex standardized address object but does include information like geocodes (which are important for calculating tax).
