AddressVerify

About AddressVerify

AddressVerify is a real-time API designed to validate, standardize, and enrich U.S. residential address data. It instantly verifies if an address is a real, deliverable residence, filtering out commercial properties, fake entries, and undeliverable locations. Beyond basic validation, it classifies the property into one of seven specific home types and provides an estimated current market value. This tool is built for businesses that rely on high-quality address data for marketing, sales, and service delivery. Its core value proposition is transforming raw lead data into actionable intelligence, enabling precise targeting, improved operational efficiency, and significantly higher return on investment for campaigns and outreach efforts.

Features of AddressVerify

Real-Time Residential Verification

The API validates addresses instantly against authoritative databases. It confirms deliverability, corrects common typos and formatting errors, and standardizes addresses to USPS standards. Crucially, it filters out non-residential addresses, ensuring your lists contain only genuine homes and not businesses, vacant lots, or invalid entries.

Home Type Classification

Every verified residential address is classified into one of seven distinct property types: Single-Family, Multi-Family, Condo, Townhouse, Apartment, Manufactured Home, or Lot. This granular data allows for hyper-targeted marketing strategies and service offerings tailored to the specific characteristics of a prospect's dwelling.

Estimated Home Value Data

The API provides a current estimated market value for verified residential properties. This enables segmentation of audiences by property value, allowing businesses to prioritize high-value leads, tailor product offerings, and customize messaging to match the financial profile of the homeowner.

Data Standardization & Error Correction

AddressVerify automatically corrects misspellings, fills in missing components like ZIP codes, and standardizes the format of addresses to a consistent structure. This cleanses your database, improves deliverability for direct mail, and ensures seamless integration with other systems like CRMs and marketing platforms.

Use Cases of AddressVerify

Targeted Marketing Campaigns

Marketing professionals use the API to ensure campaigns reach only verified residential households. By filtering out invalid addresses and segmenting lists by home type and value, they can craft relevant messages, boosting engagement rates and overall campaign effectiveness.

Lead Generation & Qualification

Lead generation companies integrate the API to validate and enrich lead data in real-time. This process filters out fake or low-quality leads, provides crucial property context, and delivers higher-quality, actionable prospects to clients, improving conversion rates.

Home Services Advertising

Contractors, remodelers, and service providers tailor their advertising by targeting specific home types. A roofing company can focus on single-family homes, while a condo renovation service can target apartment and condo dwellers, ensuring ad spend reaches the most relevant audience.

Direct Mail Optimization

Direct mailers verify the deliverability of every address on a list before sending costly materials. This eliminates waste from undeliverable mail, increases response rates by reaching real residences, and improves ROI on print and postage budgets.
