AddressVerify

About AddressVerify

AddressVerify is the definitive real-time API for U.S. residential address intelligence, engineered to supercharge data-driven marketing and lead generation. In a landscape cluttered with inaccurate data, AddressVerify goes beyond simple validation. It instantly confirms if an address is a real, deliverable residence, filters out commercial properties, PO boxes, and fake entries, and enriches each record with critical property intelligence. This includes classification into one of seven specific home types—from Single-Family homes to Condos and Manufactured Homes—and provides an estimated current market value. Built for scaling businesses, its core value proposition is transforming raw lead data into a high-quality, actionable asset. By ensuring every address is accurate, residential, and enriched with context, companies can achieve unprecedented precision in targeting, dramatically improve campaign ROI, and allocate resources to the highest-value prospects. It's the essential tool for marketing professionals, lead gen companies, home service advertisers, and direct mailers who are serious about growth, efficiency, and dominating their market with data.

Features of AddressVerify

Real-Time Residential Verification & Filtering

Our API processes addresses in milliseconds, performing live checks against authoritative datasets to confirm deliverability. Crucially, it intelligently filters out non-residential addresses like businesses, warehouses, and vacant lots, as well as blatantly fake or undeliverable entries. This ensures your marketing spend and operational efforts are concentrated solely on genuine residential households, eliminating waste and building a foundation of pure, high-quality data from the very first touchpoint.

Property Type Classification

Gain deep insights with automatic classification into seven distinct residential property types: Single-Family, Multi-Family, Condo, Townhouse, Apartment, Manufactured Home, and Lot. This granular detail allows for sophisticated audience segmentation and hyper-targeted campaign strategies. Tailor your messaging for condo owners versus single-family homeowners, or identify multi-unit properties for scalable service offerings, enabling personalized engagement that drives significantly higher conversion rates.

Home Value Estimation

Unlock the power of value-based targeting with estimated current market values for verified properties. This feature enables you to segment your audience by equity and investment level, prioritize high-value leads for premium services, and customize your outreach messaging to resonate with the financial profile of the homeowner. It transforms your lead list from a simple directory into a prioritized roadmap for maximum sales efficiency and resource allocation.

Address Correction & Standardization

Automatically clean and perfect your address data on the fly. The API identifies and corrects common errors like misspellings, transposed numbers, and incorrect abbreviations. It then standardizes every address into a consistent, postal-approved format. This eliminates mailing errors, ensures seamless CRM integration, and guarantees that your data is always analysis-ready, reliable, and professional for every downstream application.

Use Cases of AddressVerify

Optimizing Direct Mail Campaigns

Drastically increase your direct mail response rates and ROI by verifying every address on your list is a deliverable residence. Eliminate the cost of printing and postage for fake or commercial addresses. Further, use property type and value data to segment your mailing lists, sending relevant offers to specific homeowner groups (e.g., roof repair mailers to single-family homes, renovation offers to high-value properties), making each piece of mail more impactful and personalized.

Supercharging Lead Generation for Home Services

For companies in roofing, solar, landscaping, or remodeling, lead quality is everything. Integrate AddressVerify at the point of capture to instantly validate and enrich lead data. Filter out non-residential leads and prioritize incoming requests based on property type and estimated value, allowing your sales team to focus immediately on the most promising, high-intent homeowners, thereby shortening sales cycles and improving close rates.

Enhancing CRM and Marketing Automation Data

Clean and empower your existing customer databases. Run your CRM lists through the AddressVerify API to standardize formats, remove dead entries, and append valuable property intelligence. This data enrichment creates powerful new segmentation fields (e.g., "Condo Owner," "High-Value Property") within your marketing automation platform, enabling highly personalized email nurture streams, retargeting campaigns, and lifecycle marketing based on concrete property attributes.

Building Targeted Audience Segments for Digital Ads

Create laser-focused lookalike audiences and targeted segments for platforms like Meta and Google Ads. Use verified residential addresses, classified by home type and value, to build custom audience lists. Upload these to ad platforms to target current customers or find new prospects with similar property profiles, ensuring your digital ad spend reaches households with the highest propensity to engage with your specific product or service offering.

Frequently Asked Questions

How accurate is the home value estimation?

Our home value estimates are derived from current market data and proprietary models, providing a reliable benchmark for segmentation and prioritization. They are designed for marketing and lead scoring purposes to identify value tiers (e.g., high, medium, low). For precise financial valuations such as refinancing or sale, we recommend consulting a licensed appraiser or real estate professional.

What is the difference between AddressVerify and a standard address validation service?

Standard services often only check if an address format is postal-compliant, not if it's an actual, occupied residence. AddressVerify is specialized for residential marketing. We actively filter out commercial properties, PO Boxes, and fake addresses, and we add the crucial layers of property type and value intelligence that generic validators do not provide, making it uniquely suited for targeted outreach.

Can I integrate AddressVerify into my existing website or CRM?

Absolutely. AddressVerify is a developer-friendly REST API designed for easy integration. We provide comprehensive documentation with code examples to help your team implement real-time verification into lead forms, batch processing for existing lists, or backend systems. It seamlessly connects with most CRMs, marketing platforms, and custom applications to fit into your workflow.

What does the "100 free API calls" offer include?

Our free tier allows you to test the full power of the API with 100 verifications at no cost and with no credit card required. This includes all features: real-time residential verification, property type classification, home value estimation, and address standardization. It's the perfect way to validate the impact on your data quality and see the enriched results firsthand before scaling up.
