In addition to supporting 5 digit Zip Codes all CDXZipStream versions have a built-in function for Zip+4 address correction CDXZip4.  This will allow you to get an exact zip code for any US address, correct errors and provide a USPS standardized output.  The CDXZip4 function is accessed by right-clicking on any cell in your worksheet. Then click on "CDXZipStream Functions", select "CDXGeodata Functions" and "Insert CDXZip4 function".   

Addresses can be entered in single or multi-line address formats.  As with other CDXZipStream functions,  text or cell references can be entered.  Requests are checked against a USPS database to determine the correct format and if it is deliverable.   Addresses not validated with return "Unknown or Invalid Address".  The results should closely match the individual results returned at the USPS site.

To gain access to this functionality you must have a CDXGeoData API Key which is not part of the CDXZipStream license.  Tokens are used to access CDXGeoData with different levels for each service request.  This Zip+4 address verification will require 5 tokens per request.  

A free CDXGeodata API key to try out the service can be obtained on our website.  Click the "Generate API Key" button to get your free key. The free key can be used for evaluation, development or non-profit use and is good for 24 hours. Users are allowed to generate one free key each day.  The key can also be used to evaluate our other CDXGeodata Excel templates.

For higher usage levels and commercial use purchase blocks of additional token requests at this link.  A single API key can be used for all the CDXZipStream licenses in your account. The key is licensed by request and not users.The tokens are available for up to one year and include an additional development API key with 1000 tokens per month. The development key will reset each month. No automatic rebilling.

CDXZipStream licensed users can request a development account by contacting support@cdxtech.com.
