Summary

Automated address validation is presented as a key tool for reducing domicile fraud, in which individuals use false, misleading, vacant, or otherwise inappropriate addresses to create accounts, obtain loans, or avoid scrutiny. Basic confirmation that an address exists may not be sufficient, so effective systems combine USPS-based standardization, Coding Accuracy Support System processing, Delivery Point Validation, Residential Delivery Indicator checks, and ZIP+4 data to assess formatting, deliverability, and property type. Geocoding and location mapping can add geographic context by identifying address clusters, comparing locations linked to a user, distinguishing residential and commercial properties, and incorporating property records or other external data. A layered approach that also uses risk scoring and behavioral analytics can help identify anomalies while real-time validation during onboarding may reduce manual reviews and friction for legitimate users. Didit is described as offering an API that combines these capabilities, including real-time verification, geocoding, configurable rules, and fraud-risk assessment.
