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.

NLS 5.15 and later

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

Select Override Mailing Name and enter the addressee’s name as you would like it to appear in the fields provided.

Batch Delivery Point Validation

This option will allow for the validation of all addresses already entered into NLS.

Select View > Processing > DPV ValidationProcessing > DPV Validation from the shortcut bar to display a dialog showing the number of unique addresses found in the database under contact, relationship, vendor, CDFI, and statement categories.

Select Process All to validate all addresses or Process Unvalidated to process only address that have not been validated. Click Process to begin validation of the addresses.

For reference, when the validation process is complete, click Write Unvalidated Addresses to a Text File to save unvalidated addresses to a text file; enter a filename and choose the location to save the text file.

Click Done to dismiss the dialog.
