AddressVerify

About AddressVerify

AddressVerify is a powerful, real-time API designed to transform how businesses handle and utilize U.S. residential address data. At its core, it's more than just a simple address checker; it's a comprehensive data intelligence tool that validates, classifies, and enriches address information instantly. The API is engineered to filter out non-residential, commercial, or fake addresses, correct formatting errors, and standardize data to ensure you're working with only the highest quality, deliverable residential leads. Its unique ability to classify a property into one of seven specific types—such as Single-Family Home, Condo, or Apartment—and provide an estimated current home value sets it apart. This depth of insight is invaluable for data-driven decision-making. Built with a mobile-first and app-centric philosophy, AddressVerify offers seamless integration and a smooth user experience, allowing developers and businesses to embed robust verification directly into their workflows, CRMs, or marketing platforms. It's the essential tool for marketing professionals, lead generation companies, home service advertisers, and direct mailers who need to improve campaign ROI, enhance lead quality, and execute precise, targeted outreach by ensuring every piece of data is accurate, relevant, and actionable.

Features of AddressVerify

Real-Time Residential Verification

AddressVerify processes and validates addresses in real-time, providing instant confirmation of an address's residential status and deliverability. This goes beyond basic USPS validation by actively filtering out commercial properties, PO boxes, and completely fake or non-existent entries. The immediate feedback loop ensures your databases are cleaned on the fly, preventing low-quality data from ever entering your system and saving significant resources on wasted outreach efforts.

Property Type Classification

This advanced feature analyzes a verified residential address and classifies it into one of seven distinct property types: Single-Family, Multi-Family, Condo, Townhouse, Apartment, Manufactured Home, or Lot. This granular data unlocks powerful audience segmentation, allowing marketers to tailor campaigns specifically for condo owners versus single-family homeowners, for example, leading to more relevant messaging and significantly higher engagement rates.

Estimated Home Value Intelligence

AddressVerify enriches address data with an estimated current market value for the property. This financial insight allows businesses to segment audiences by property value, prioritize high-value leads for sales teams, and customize service offerings or product recommendations. It transforms a simple address into a key indicator of potential customer lifetime value and purchasing power.

Data Correction & Standardization

The API automatically corrects common input errors, such as misspellings, incorrect abbreviations, or missing suite numbers, and standardizes addresses into a consistent, postal-approved format. This ensures perfect deliverability for direct mail, improves match rates for data append services, and maintains a clean, professional database that enhances operational efficiency across all departments.

Use Cases of AddressVerify

Targeted Marketing Campaigns

Marketing teams can leverage AddressVerify to ensure their digital and physical campaigns only target verified residential households. By combining property type and home value data, they can create hyper-segmented campaigns—like targeting high-value single-family homes for premium landscaping services or apartment complexes for renter's insurance—dramatically increasing conversion rates and marketing ROI.

Lead Generation & Qualification

Lead generation companies and sales teams use the API to scrub incoming lead lists in real-time. By instantly filtering out non-residential and invalid addresses, they guarantee clients only pay for high-quality, actionable leads. The added property type and value data further qualify leads, allowing for immediate prioritization and more efficient sales funnel management.

Home Services Advertising

Contractors, remodelers, solar companies, and other home service providers can tailor their advertising with precision. The API allows them to target specific property types (e.g., targeting townhouses for exterior painting or manufactured homes for HVAC services) and estimate project potential based on home value, ensuring their ad spend attracts the most likely and valuable customers.

Direct Mail Optimization

For businesses relying on direct mail, AddressVerify is essential for list hygiene. It verifies the deliverability of every address, filters out commercial drops, and ensures accurate formatting for postal automation discounts. This reduces waste from undeliverable mail, increases response rates, and provides a clear picture of the true residential reach of any mailing campaign.

Frequently Asked Questions

How accurate is the home value estimate?

The estimated home value provided by AddressVerify is a current market valuation derived from a combination of public records, recent sales data, and proprietary modeling. It is designed for segmentation and prioritization purposes. While highly accurate for identifying value brackets (e.g., $300k-$500k), we recommend it as a guide for marketing strategies rather than a formal appraisal for real estate transactions.

What is the API's latency for real-time verification?

AddressVerify is built for speed and efficiency. Typical API response times are under 500 milliseconds, ensuring real-time validation without causing delays in your user sign-up flows, checkout processes, or lead capture forms. This performance is consistent across all endpoints, providing a seamless experience for both your business and your end-users.

Can I verify addresses in bulk or just one at a time?

The API supports both individual, real-time verification for form fills and high-volume batch processing for cleaning existing databases. You can seamlessly integrate the single-address endpoint into your apps or use our batch tools to upload and cleanse large lists of addresses, making it versatile for both operational and data hygiene projects.

How does AddressVerify differentiate residential from commercial addresses?

Our system uses a sophisticated multi-source verification process that cross-references addresses against comprehensive datasets of known residential dwellings. It identifies and filters out addresses classified as commercial properties, government buildings, industrial lots, and vacant land, ensuring you only receive confirmation for genuine, occupied residential locations.
