Purchasing Data Updates for CDXZipStream

CDXZipStream, our Excel add-in for zip code and location-based analysis, is an intentionally non-subscription, pay-as-you-go software so our clients can decide for themselves how often to purchase new data.  The need for data updates certainly varies depending on what data is used and how it is applied, and ultimately we feel this decision is best left up to our clients.

CDXZipStream updates are available as a one-time purchase and as a one-year subscription, where twelve updates are provided monthly.  Updates apply to CDXZipStream Basic and Premium versions, and to a separate Canadian database of postal codes.  Please see the last portion of our price list for pricing for all update versions.

Our basic and premium data feeds for zip codes are updated with new data every month.  Since zip codes are frequently retired or added by the U.S. Postal Service, this data is most subject to change. Out of about 42,000 zip codes in the U.S., an average of 0.9% of records change per month, and 11.2% of records change per year.  Unemployment data (provided in county, state, and Core Based Statistical Area data feeds) are also added and updated monthly.

All our other data feeds, which are primarily based on U.S. Census Data, are updated less frequently.  Data from the American Community Survey (ACS), which will soon be replacing much of the data from the ten-year census, is updated annually, usually in the last quarter of the following year.  We will be using our newsletter to announce updates to these data feeds as they occur.

When you need to update your database, click on the "License Information and Software Updates" icon on the CDXZipStream toolbar, and select "Data Updates" to login to your account and purchase an update. If you've forgotten your user name or password, please contact us at support@cdxtech.com. (Alternatively, your username is normally your email address, and you can retrieve a new password by selecting "Forgot your password?" to the right of the sign-in area.)  For our clients who have purchased support plans, we send an email notification when monthly updates are available.  For more information please call 1-877-239-8321 or contact us at sales@cdxtech.com.

Once a new update has been purchased, or to obtain a monthly update as part of a subscription plan, you can select the “Product Management” under the My Account area of our website (on the left-side menu), and click on “Download Data Files” to download and install the new database.  Alternatively, you can also click on “Buy Data Updates” here to purchase updates.

So, how often should you get updates?  First, consider how critical accuracy is for your application.  If you’re using CDXZipStream to verify addresses in a direct marketing campaign, and even a small percentage of non-valid addresses can make or break the return on investment, consider getting a year’s subscription so you get new data every month.  For non-critical applications, we generally recommend updates at least every six months.  In fact, you’ll see a reminder when you open CDXZipstream if your data is more than six months old.  (You can disable this feature by clicking on the “License Information and Software Updates” icon on the CDXZipStream Toolbar, and unselecting the “Warn if Zip Code Data Out of Date” checkbox.)

Please note that CDXZipStream functions related to driving and mapping use information from Microsoft MapPoint, and are only as good as the MapPoint version installed on your computer.
