Printed Address Examples, Optional and Required Fields
The only required fields for your address file are street address, city, state and zip code. City, state
and zip code can be all in one field or in separate fields. In addition to the required fields, there
are also several optional fields.
Optional Generic Addressee
If you would like to add a generic addressee such as “or current resident” to each postcard choose one
of these two options: during the order process you can choose to have expresscopy.com add it to each
postcard or you can add a generic addressee field to your address list. If you choose to add a generic
addressee to your address list, it cannot be in the same field as the name or company fields.
Reasons to add a Generic Addressee
If you would like your postcard to be delivered regardless of the current resident of the address, you
must add a generic addressee. Also, less of your postcards will come back undeliverable.
Example: A postcard notifying each household that a new business is in their neighborhood.
Reasons not to add a Generic Addressee
If you would like a particular person/family to receive your postcard, you should not add a generic
addressee. For first class mail, if the recipient no longer lives at that address it will be forwarded to their
new address based on the National Change of Address (NCOA) information that we receive. For standard
(bulk) mail, if the recipient no longer lives at that address the postcards will be discarded by the United
States Postal Service.
Example: A postcard inviting your customers to an exclusive event.
CASS Certification
(Only applies to orders for both addressing AND mailing services. Addresses submitted for addressing-only orders will not be CASS certified.)
To improve the accuracy of addresses on all pieces mailed by expresscopy.com USPS CASS™ certified software compares submitted addresses to a constantly updated USPS database of addresses. The addresses are checked for validity and proper formatting. "Best-matches" are updated and "no-match" or "multiple-matches" are failed and removed from the list (you are not billed for these failed addresses). This software does not verify if the intended recipient actually resides at that address or if the property is occupied.
Expresscopy.com then calculates the variance between the addresses submitted against the result of the CASS™ certification process.
- If 90% or more of the addresses certify, we will continue with order processing, printing only those that certify up to the ordered amount
- If less than 90% certify, we will hold order processing and you will be contacted for advice
- If the quantity certified is 25% or greater than the ordered amount, we will hold order processing and you will be contacted for advice
If you would like to check your addresses (one at a time) for validity, you can do so at

CASS™ enables us to maximize deliverability and minimize return of mailed pieces due to invalid addresses. For more information on the USPS CASS™ system, please visit:

Ordering Extra Postcards
When ordering your postcards you can choose an option to have one postcard mailed to yourself. If you
would like to have more than one postcard sent to yourself, there are two ways to do this:
- Add another item to your order for Print-Only postcards (with the postcards coming directly to you).
Since this item is a separate shipment, this item must meet the $45 minimum. If you do not want your
postcards to have addresses on them, please choose this option.
- Add your name and address to your address list as many times as you like. CASS Certification
automatically deletes duplicates, so you must write a note in your order stating that the duplicate
addresses in your file are intentional. Each of these postcards will have the duplicate address on them.
