A function named CDXZip4 is included with CDXZipStream and provides address correction and USPS Zip+4 approved formatting using our CDXGeoData web service. Available in all versions of CDXZipStream with a CDXGeoData API key, you can now perform address verification and correction using U.S. Postal Service databases. Get address data in standard format and find ZIP+4 Codes even for addresses with missing data.
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 that is good for 24 hours. We also offer CDXZipStream registered users a free development account available at the following link with 1000 tokens per month. The account can be used for evaluation, development and non-profit use.
The CDXZip4 function can be used by right-clicking on any cell in your worksheet and selecting Insert CDXZip4 Function from the new CDXGeoData Functions drop down menu. Provide the input address information as either a single-line or multiple line address.
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.
Tokens are used to access CDXGeoData with different levels for each service request. This Zip+4 address verification will require 5 tokens per request. Any number of users can access the CDXGeodata service with a single API key. The tokens can also be used with the free CDXGeodata templates available on our web site.
