NCOALink (National Change of Address)
As a service provider, our NCOALink service makes change-of-address information available to mailers in order to help reduce undeliverable mail pieces as they enter the mail stream. The NCOALink process improves mail deliverability by providing mailers with current, standardized, delivery point coded addresses for individual, family, and business moves.
DSF2 (Delivery Sequence File)
Another postal processing solution approved by the USPS to assist with identifying inaccurate and incomplete addresses on you database by validating it against the USPS master database of all 165+ million delivery points. This process helps you further enhance mailing data qulity – based on USPS delivery points. Using the DSF2 product helps to reduce the amount of undeliverable-as-addressed (UAA) pieces, which in turn will result in more efficient postal mail processing and delivery operations.
Using the DSF2 file on your mailing list can provide several benefits:
- Identify if an address has been vacant for more than 90 days
- Identify if an address is at a business or residential location
- Identify records that are seasonally occupied
- Identify records that are located at an educational institution
- Identifies if an address is delivered to a curb-side mailbox or by a door-slot. This information allows for more targeted mailings.
- DSF2 processing is one of the approved methods outlined in the Domestic Mail Manual for sequencing mail pieces in walk-sequence. This could allow you to qualify for lower postage rates. This service is available as a stand along process or combined with NCOA processing.
LACSLink (Locatable Address Conversion System)
The Locatable Address Conversion System (LACSLink) service provides mailers an automated method of obtaining new addresses when a 911 emergency system has been implemented. 911 address conversions normally involve changing rural-style addresses to citystyle addresses, but in some instances conversions may result in the renaming or renumbering of existing city style addresses. Address Management Systems (AMS) offices across the country collect and transfer information for this database to the National Customer Support Center in Memphis TN which is the main office for all of USPS.
Example
Before LACSLink Conversion: Rural Rount 16, Sweetwater, GA 30093
After LACSLink Conversion: 53 Heather Lane, Sweetwater, GA 30093
Input address information provided by a mailer to the LACSLink licensee is first standardized/CASS to include the ZIP + 4 Code where available. Once the address is standardized and the ZIP+4 Code applied, an attempt is made to match the address against the LACSLink file. If an exact match is made with the old address information on the LACSLink file, the LACSLink licensee is permitted to provide the 911 conversion address to the mailer.
