Address Element Correction (AEC) – USPS Definition

Address Element Correction (AEC)

A process that identifies and revises incomplete or incorrect computerized address files and then attaches ZIP+4 and carrier route codes. It entails computer matching address records that cannot be coded using CASS-Certified address matching software. AEC can correct or add missing address elements (e.g., directionals like N or NW or street suffixes like AVE or DR) and return a standardized address along with information identifying the correction.
