What is LACSLink?
The LACSLink Product is a secure dataset of converted addresses that primarily arise from the implementation of the 911 system, which commonly involves changing rural-style addresses to city-style addresses. The LACSLink Product also contains existing city-style addresses that have been renamed or renumbered.
The LACSLink Product:
- Reduces undeliverable mail by providing the most current address information for matches made to the LACSLink file.
- Lowers mailer costs by reducing the number of undeliverable and duplicate mailpieces by using the most current address information.
- Provides the opportunity for faster product/service marketing through accurate mail delivery.
LACSLink has three licensing categories:
- The LACSLink Developer License grants the right to develop a LACSLink interface for internal purposes and third parties.
- Initial License Fee: $1,690.00
- Annual License Fee: $490.00
- The LACSLink Distribution License grants Developers the right to distribute the LACSLink interface and redistribute the LACSLink data.
- Annual License Fee (Interface Distribution): $1,890.00*
- Annual License Fee (Data Distribution): $490.00
- The LACSLink End User Agreement grants the right to use the LACSLink Product to update addresses and mailing lists both internally and for third parties. End Users may receive data fulfillment directly from the USPS®.
- Annual License Fee: $490.00*
* The initial licensing year is prorated.
Once you have selected the appropriate licensing category, the next step is to complete the certification process. The process includes the completion of the following documentation:
- Confidentiality Statement
- Self-Certification Statement
- Key Personnel Listing
Upon completion of the certification documents, the appropriate license must be executed, including the payment of licensing fees.

Licensing Announcement: Issue with Downloading Both SHA-1 and SHA-256 Products on Electronic Product Fulfillment (EPF)
This announcement details an issue with downloading both the SHA‐1 and SHA‐256 versions of the products using the SOAP Web Services (ColdFusion).
To comply with the recommendations from the December 2014 Office of Inspector (OIG) audit of the NCOALink® program, the USPS® will begin the transition from SHA‐1 to SHA‐256 technology as the method for data encryption.
As a reminder, the Electronic Product Fulfillment (EPF) website will be migrated to a new server Saturday, March 15.
The CASS™ certification process is designed in cooperation with the mailing industry to improve the accuracy of postal codes, i.e., Five-Digit ZIP Code®, ZIP + 4®, delivery point (DPCs), and carrier route codes that appear on mailpieces.
The SuiteLink® product enables customers to provide improved business addressing information by adding known secondary (suite) information to business addresses, which will allow USPS delivery sequencing where it would not otherwise be possible.
