CASS Certification
Coding Accuracy Support System (CASS™) is a United States Postal Service (USPS) acronym that is widely used when referring to verification status of an address list. For an address list to receive CASS™ certification, it must be checked against the USPS Address Matching System (AMS), and the barcode and the corresponding 11-digit delivery ZIP code must be added.
Only addresses with both the delivery ZIP code and barcode are eligible for automation bulk mailing rate discounts. To ensure a mailing list is up to date, it should undergo CASS™ certification every three months for carrier route mailings, and six months for non-carrier route mailers.
Allmail USA uses the latest CASS™ certification technology to help our clients ensure a high percentage delivery rate and keep the cost of their mailing as low as possible.

NCOA
National Change of Address (NCOA); you could call this address updating. If you haven’t kept up with your database and whether any addresses have actually changed or not you may be surprised at what you will find out. Consider having your database updated in combination with an ancillary endorsement to be as current as possible. Accurately addressed mail helps keep your name in front of your clients, increase revenue and lower mailing costs.

File Conversion
We have reasonable conversion costs when data conversion is needed and in most cases your file work is included in any complete direct mail project. To help keep costs down, please ensure that all your data elements are consistent from record to record. This simply means that in each position within a record, the same kind of data is in that same position in each record.
For example: First, Last, Title, Company, Address1, Address2, City, State, Zip Code. If any of these elements are missing, make sure to leave the field blank and go on to the next field.
For our software to quickly and accurately process your files it needs to know what kind of data is in each field. The most important fields are the Address, City, State and Zip Code fields. If your company name ends up in the address field, there will be no way to verify the accuracy of that address. In addition, pieces that are addressed with misplaced elements will leave a negative impression with the recipient of your mail piece.

Error Codes
Our CASS™ software codes all records during the certification run and these codes can give clues as to why a particular record may not be deliverable including an address that no longer exists. By default, we remove all records that do not fully code and can provide these back to you upon request, along with their error codes and a code sheet to help you complete these records for future use.
