AddressVerify

About AddressVerify

AddressVerify is a powerful and easy-to-use API designed to help businesses ensure their address data is accurate, residential, and actionable. In simple terms, it's a tool that checks if a mailing address is a real home, tells you what type of home it is, and even provides an estimated value—all in real-time. This is crucial for companies that rely on accurate customer data, such as those in marketing, lead generation, home services, and direct mail. The main value of AddressVerify is its ability to instantly filter out fake, non-residential, or incorrectly formatted addresses. This means you stop wasting time and money on bad leads and can instead focus your efforts on reaching real, potential customers at their actual homes. By improving your data quality from the very start, AddressVerify helps you run more targeted campaigns, improve your return on investment, and connect with your audience more effectively. It's built for developers and businesses of all sizes, offering a straightforward way to integrate precise address validation into any application or workflow.

Features of AddressVerify

Real-Time Residential Verification

This core feature validates any U.S. address instantly as you collect it. It doesn't just check if an address exists; it specifically confirms whether it's a deliverable residential address. It filters out commercial properties, PO boxes, vacant lots, and completely fake entries, ensuring your lists only contain genuine homes. This immediate feedback prevents bad data from ever entering your system, saving you from costly mistakes down the line.

Home Type Classification

AddressVerify goes beyond simple validation by classifying each verified residential property into one of seven specific types: Single-Family, Multi-Family, Condo, Townhouse, Apartment, Manufactured Home, or Lot. This detailed insight allows for incredible precision in your marketing and outreach. You can tailor your messaging and offers based on the type of home, leading to much higher engagement rates.

Estimated Home Value Data

For an even deeper layer of insight, the API provides an estimated current market value for the home. This powerful data point allows you to segment your audience by property value. You can identify and prioritize high-value prospects, tailor your service tiers or product offerings accordingly, and allocate your sales and marketing resources more strategically for maximum impact.

Address Correction & Standardization

The API automatically corrects common typos, missing suite numbers, or incorrect abbreviations in addresses. It then standardizes the format of every address to meet USPS guidelines. This process, known as address cleansing, ensures your data is clean, consistent, and ready for use in any system, from CRM platforms to direct mail software, eliminating delivery issues.

Use Cases of AddressVerify

For Targeted Marketing Campaigns

Marketing teams can use AddressVerify to build highly qualified contact lists from the ground up. By ensuring every address is a real residence and knowing the home type and value, marketers can create hyper-personalized campaigns. For example, a lawn care company can target single-family homes, while a security system provider might focus on higher-value properties.

For Lead Generation Companies

Companies that sell leads to others have a responsibility to provide high-quality data. Integrating AddressVerify into their lead capture forms or data processing pipelines guarantees that every address lead is verified as residential in real-time. This dramatically improves the accuracy and conversion potential of the leads they deliver to clients.

For Home Services Advertisers

Businesses like roofers, remodelers, or solar panel installers can use the home type and value data to tailor their outreach. They can create specific ad sets for townhouses versus single-family homes or develop different service packages for different property value ranges, making their advertising spend much more efficient and effective.

For Direct Mail Campaigns

Direct mail is expensive, and sending mail to invalid or non-residential addresses is a huge waste. AddressVerify ensures every address on a mailing list is a deliverable residence before the mail is ever sent. This boosts response rates by getting your materials to real people, reduces return-to-sender costs, and maximizes the return on your direct mail investment.
