AddressVerify.io — Analytics & Data

What AddressVerify.io does

AddressVerify.io is a real-time address verification and property data API. It validates residential addresses in the US, corrects errors, standardizes formats, and filters out non-residential or fake addresses. In the same API call, it returns property details such as home type, estimated home value, bedrooms, bathrooms, living area, year built, lot size, tax assessment, and listing data.

Problem it solves

Lead generation and data enrichment teams often pay for leads that turn out to be invalid or not qualified. AddressVerify.io ensures you only pay for leads that are real and fit your criteria. By verifying the address and enriching it with property intelligence, you can score leads upfront and reduce wasted spend.

Who it is for

It is built for businesses that buy or generate residential leads, such as insurance, solar, real estate, and home services companies. It is also useful for data providers and platforms that need accurate address data. It is not intended for non-residential address verification (e.g., commercial properties) or for international addresses.
