PER/ZIP4 Includes PER/SLK, a SUITELink™ Interface
In August of 2011 the United States Postal Service began requiring that all CASS Certified™ postal coding solutions perform SuiteLink processing as part of CASS processing. PER/SLK is the module that adds SuiteLink functionality to PER/ZIP4. PER/SLK is automatically installed with PER/ZIP4 and cannot be bypassed or disabled.
According to USPS estimates, nearly 1.8 billion mailpieces are sent to business addresses in large buildings without the correct suite number. Getting these mailpieces delivered depends entirely on the carrier's personal knowledge. But the carrier might not always know where the mail should be delivered and the mailpiece can end up as undeliverable-as-addressed (UAA).
SuiteLink is designed to help fix these incomplete or inaccurate business addresses by matching to the business name and providing the correct suite number. This allows the mailpiece to be correctly and completely addressed to a valid delivery point and avoid becoming possible UAA mail. With SuiteLink, mailers experience more efficient processing and delivery of their business-addressed mail.
SuiteLink processing is performed by all three PER/ZIP4 interfaces; Interactive, Callable Program (API), and Batch.
While using the PER/ZIP4 interactive interface, if SuiteLink processing results in the conversion of an address, the message Secondary address information updated by SUITE-Link will appear at the bottom of the screen.
Callable Program (API) Interface
While using the PER/ZIP4 callable program interface, if SuiteLink processing results in an address being updated, the updated address will be returned and the informational code “SLK” will appear in the error code (ECOD##) field.
While using the PER/ZIP4 batch interface, if SuiteLink processing results in an address being updated, the address will appear on the PER/ZIP4 Coding Report with an “SLK” informational code. This informational code will appear for each address that is updated as a result of SuiteLink processing.
Addresses converted as a result of SuiteLink processing will also appear on the PER/ZIP4 SuiteLink Address Updates Report.
Note: Just like “ALT”, “BNR”, and “LLK”; “SLK” is an informational code and not a true error.
