Check Pay address confirmation 

Not Available in Canada

This service is unavailable for users of our Canadian products.

After you enter the address information for your payee, Quicken runs an algorithm that helps to find and correct important details required for sending the check. Quicken will display any address suggestions, which commonly include changes to the street address or zip code. This to ensure reliable delivery through USPS First Class Mail. You can choose whether to save the new suggested address for the payee or to use your original address entry. 

Select Done when you are through reviewing the address.
