How to bypass an address found in the Early Warning System (EWS) database using CODE-1 Plus

The Early Warning System (EWS) was devised by the USPS to prevent address records from miscoding due to a delay in postal data reaching the USPS address matching files. The less recent the ZIP+4 File, the higher potential you have for miscoding addresses. When a valid address is miscoded because the address it matches to in the ZIP+4 File is inexact, it will result in what is termed a “broken address.” Once an address is broken, the effect is permanent without manual intervention.

Using the EWS Auxiliary File with CODE-1 Plus will prevent “broken addresses” from occurring. EWS consists of records containing partial address information limited to the ZIP Code, street name, pre- and post-directionals, and a suffix. For an address record to be EWS-eligible, it must be an address not present on the most recent
monthly production ZIP+4 File.


If you are executing our batch driver, C1BM00, you can use the CONFRM parameter to bypass certain addresses/records (on the EWS file) based on some criteria on the input record (ZIP code, special character, etc.). All confirmed address will not be processed by CODE-1 Plus but will be added to the Coded file ASIS.
