Easy, affordable address verification and postal data access

Works in Microsoft Excel

Do your address correction and ZIP Code analysis in a familiar software environment. No need to upload your file – get your data in real time through the web.

Patented interface

Using our intuitive interface, you simply specify the data you want and where you want it. Commonly-used interface settings are stored and can be used again in other files.

Dynamic updating

Your spreadsheet updates automatically using embedded CDXStreamer formulas that link to the data. Both your data and software version are always the latest available.

Easy access

Invisible until you need to use it. Just click on the CDXStreamer commandbar in your worksheet, or right-click on any cell in your worksheet to get data or verify addresses.

Data driven

Do hundreds of data requests at a time. Data is available for ZIP+4, TIGER/ZIP+4, and Canadian postal codes. And it’s all on our servers – you don’t need to download or maintain massive databases.
