Maximize address quality, minimize mailing cost.

Standardizing, sequencing, and tracking are examples of services provided by the U.S. Postal Service® and offered to mailers to manage and increase the accuracy of their mailing addresses.

Address Element Correction & AEC II® Service

Corrects and standardizes address elements.

When CASS Certified™ address-matching software cannot match an address to the ZIP + 4® Product, the address becomes a candidate for Address Element Correction (AEC). AEC is a service that corrects and standardizes address elements. AEC processing may transform problem addresses into accurate, standardized addresses, which allows mailers to take full advantage of automation discounts.

AEC focuses on correcting address element deficiencies such as misspellings, nonstandard abbreviations, incorrectly joined elements, improperly ordered elements, address lines containing data other than the actual address, and missing elements. After resolving address element issues, AEC matches the address against the ZIP + 4 Product using CASS Certified address-matching software, resulting in a correct, standardized address.

AEC II™ is the next generation of AEC. AEC II uses Delivery Force Knowledge™ to correct the errors in addresses that are not correctible by existing programs. Delivery Force Knowledge leverages the efforts of local delivery unit employees who review bad addresses and enter corrections into an AEC II electronic process for return to the submitting customer. AEC II participants must process their file through AEC first.

For additional information contact the National Customer Support Center at 800-238-3150 or visit the AEC website on RIBBS. Click the appropriate link below to view the AEC & AEC II User Guide.

Address List Sequencing Service

Delivery order sequencing of mailers’ address cards.

Address List Sequencing Service is a manual process that is a prerequisite to the electronic process of list sequencing, Computerized Delivery Sequence (CDS). Address List Sequencing is a service provided to mailers who have mailing lists containing at least 90 percent—but not more than 110 percent— of the total possible deliveries in a 5-digit ZIP Code™ area. The Postal Service receives cards from the mailer containing mailing addresses and sequences the addresses in delivery order. The mailer can then place mail in sequence and present it to the Postal Service as carrier-ready mail.

The Postal Service does not compile mailing lists: Address List Sequencing is designed primarily for use in high-density or saturation mailings to a particular area for mailers who already maintain a list. The following levels of address sequencing are available:

  • Sequencing of address cards (DMM 507.7.3.9)
  • Sequencing of address cards, with blank cards added for missing addresses (DMM 507.7.4)
  • Sequencing of address cards, with cards added containing missing and new addresses (DMM 507.7.5).

Customers are expected to incorporate the changes in their mailings within 75 days after they receive the sequenced cards.

Address List Sequencing provides mailers:

  • Cleaner mailing lists
  • Reduced handling of mail due to the elimination of non-deliverable mailpieces
  • Increased revenue potential due to addresses added to mailing lists
  • More timely and consistent delivery

For more information about Address List Sequencing Service, contact the National Customer Support Center at 800-238-3150.

Electronic Address Sequencing

Allows electronic processing of address files for sequencing and/or qualification for CDS.

Electronic Address Sequencing Service (EAS) is available to mailers who wish to have their address lists electronically processed under one of three options:

1. DMM® 507.8.3.9 – Sequenced and non-existent addresses removed,
2. DMM 507.8.4 – Sequenced, non-existent addresses removed, and
    missing address locations identified, or
3. DMM 507.8.5 – Sequenced, non-existent addresses removed, and
    missing addresses added, if qualified.

Fees are associated with processing all levels. DMM 507.8 is required for Computerized Delivery Sequence (CDS) product qualification.

To obtain additional information about EAS contact the National Customer Support Center at 800-238-3150 or visit the RIBBS website at https://ribbs.usps.gov. On RIBBS you can view the EAS User Guide and other related documents.

LACSLink® System

An automated method of obtaining new addresses when a 911 emergency system has been implemented.

The LACSLink product provides mailers an automated method of obtaining new addresses when:

  • a 911 emergency system has been implemented to convert rural-style Addresses to city-style addresses.
  • a street address has been renamed or renumbered.

Address Management Systems (AMS) offices across the country collect and transfer information for this database to the National Customer Support Center in Memphis, TN.

The LACS service is available through all NCOALink® Full Service Provider Licensees and companies utilizing CASS Certified™ software. This service is offered as a stand-alone process or as a front-end process with the NCOALink service to ensure a high quality mailing list.

Input address information provided by a mailer to the licensee is first standardized according to Publication 28, Postal Addressing Standards to conform with U.S. Postal Service® requirements including the ZIP + 4® code. Once the address is standardized the input address is considered to be a candidate for matching against the LACSLink data under the following conditions…

  • the address matches to a Rural Route or Highway Contract Record on the ZIP + 4 file
  • the address matches a record that has an “L” in the LACS Status indicator in the ZIP + 4 file
  • the address does not match a record in the ZIP + 4 file

If an exact match is made with the old address information to the LACSLink data files, the new address should be provided to the mailer.

LACSLink benefits include…

  • reduces undeliverable mail by providing the most current address information for matches made to the LACS file
  • prevents the need for duplicate mailpieces or re-mailings after address corrections are received since the address correction is applied prior to the mailing
  • lowers mailer costs by reducing the number of undeliverable and/or duplicate mailpieces by using the most current address information
  • provides the opportunity for faster product/service marketing through accurate mail delivery

A ZIP™ Code listing (Microsoft Word Format) contains one column of ZIP Codes and quantities of records on the LACS database. Currently, there are approximately 5.8 million records on the LACS database of addresses that have been converted. (e.g., E-911 changes, etc.)

This listing will give mailers a good indication whether or not an area on their mailing list has undergone conversion based on the ZIP Code of their customers.

NOTE: Just because a ZIP Code is found on this list, mailers should not assume that all the converted addresses have made it to the file. There are parts of the country that have only reported a percentage of their changes and therefore, the LACS database is not yet complete.

For more information, contact the National Customer Support Center at 800- 238-3150.
