Commercial Mail Receiving Agencies
DPV
®
Delivery Point Validation. DPV is technology available from the U.S.
Postal Service
®
. Used in conjunction with CASS mode geocoding,
DPV enables you to verify whether an address is a deliverable
USPS
®
address.
EWS
Early Warning System. The EWS file contains addresses that did
not make it into the current USPS
®
update, and therefore do not
match. Records that have no match because they are in the EWS
file can be flagged in the EWS output column. EWS usage is not
required for CASS discounts.
The EWS file is shipped as a file named ews.niu (not in use) and
installed in the Data folder. If you want to use EWS processing,
rename this file as ews.txt. Otherwise EWS will not be used.
geocoding
The process determining the X and Y coordinates of a location by
its address.
geographic geocoding
Candidate coordinates are based on state, county, or city centroids.
This not very precise, but may be suitable for certain applications.
LACS
Link®
Locatable Address Conversion System. LACS
Link
allows business
mailers to electronically update their rural-style addresses with
locatable street-style addresses resulting from 911 emergency
response address conversions.
For example, and address like RR 1 Box 32 might be converted to
a street-style address like 141 Morrison Ave.
location code
The geocoding engine returns location code for each record it
matches or attempts to match. Location codes indicate the
accuracy of the assigned geocode. Location codes begin with an
A (Address location), S (street centroid) Z (ZIP + 4
®
centroid), or
G (geographic centroid). See
Match Codes and Location Codes
.
match code
The geocoding engine returns a match code for each record it
matches or attempts to match. Match codes allow you to determine
the quality of the address match and indicate what type of match
was made, as well as the address elements that were changed to
match the input address to the returned output address. See
