Early Warning System Return Code

Output port that indicates whether an address contains a street name that is part of a new development that the address reference data does not yet recognize.

The United States Postal Service (USPS) Early Warning System (EWS) is a list of streets that are not yet included in the reference data to ZIP+4 Code level. The list is incorporated in United States address reference data to ensure that address validation does not dismiss newly completed streets or code them inaccurately.

Early Warning System Return Code Usage

Select Early Warning System Return Code if you are concerned that an input address refers to a new street that the primary United States address reference data does not recognize. If address validation does not validate an address to ZIP+4 Code level, you can check the Early Warning System Return Code value and determine whether the address may be too new for complete validation.
