Address Fixer is a separate utility that is automatically installed with DYMO Label Software, aka DLS (that's the software you get for FREE when you buy a Dymo LabelWriter).

Using DYMO Address Fixer, you can check the recipient’s address against a database of US addresses, correct any mistakes, and automatically add the complete nine-digit ZIP+4 barcode.

To check an address simply:
1. Select one of your contacts in Dymo Label Software
2. Click the ‘Check Address’ button or select ‘Check Address’ from the ‘Address Book’ drop-down menu

The Dymo software will automatically check your contacts’ address against the database and correct it with the proper 9-digit ZIP+4 postal code, ensuring that your mail gets delivered accurately.
