Delivery Point Validation

Delivery Point Validation is a test of an address to verify that it is a valid deliverable address. Addresses entered in NLS will be validated with the database at the data center using a web service call from within NLS. This feature must first be enabled in Contact Setup > Defaults.

Support for Canadian address validation was added in NLS 5.6.

During address entry, NLS will automatically look up the address when the OK button is clicked.


An alert dialog will be shown if the address is not valid or if additional information is required for verification.

An icon will be displayed in the Address button when DPV is enabled to indicate if the entered address is:

Valid or

Invalid . A drop down list shows why the address could not be verified.

Also stored in the database are the delivery point code, delivery point verification date, address type, FIPS code, latitude, and longitude of the address.

Select Disable Address Verification to disable DPV for this address.

Selecting Disable Address Verification will also exclude this address from verification in the batch delivery point validation process.
