Address Element Correction II (AEC II)

What is AEC II?
AEC II is an enhancement to the existing AEC service, which identifies and corrects "bad" addresses using a complex computer program. "Bad" addresses that cannot be resolved using AEC are submitted, via AEC II, to delivery offices for review and resolution by the same people who deliver the mail for you every day. When USPS delivery personnel are able to identify and correct address errors, or to identify addresses that do not exist, address quality is improved.
How does AEC II work?
AEC II uses an electronic process to correct address records once delivery unit personnel have reviewed the address, which has been submitted by mailers. As addressing errors are identified, they are added to a historical database so the same addressing errors, found on different mailing lists, are not submitted again. As each new incorrect address is submitted, and AEC or the AEC II historical file is unable to make a match against either table, the record is sent to a program called Electronic Uncoded Address Resolution System (eUARS). From there, the records are sent to a post office, which services the suspected address, for possible correction.
Why let a single customer slip through your fingers?
Through AEC II service you can use the delivery knowledge of the Postal Service, nationwide, to correct those "worst of the worst" addresses that plague every mailing list. AEC II uses Delivery Force Knowledge™ methodology to help mailers resolve unrecognizable portions of an address that prevents the address from ZIP + 4 coding, which reduces the possibility of achieving mail automation discounts, through any existing address matching software.

When an address is inaccurate or missing an element, there is a chance that USPS’s Certified address-matching software may lack sufficient information to deliver a mailpiece. AEC is a process that turns problematic addresses into accurate addresses or identifies them as potentially undeliverable.
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.
