About IQUALIF U.S.

Built for U.S. teams

IQUALIF is a desktop application that turns public yellow and white pages directories into structured prospect files for U.S. sales teams, call centers, recruiters, agencies, and market researchers. Trusted since 2013, IQUALIF helps teams across all 50 states build cleaner contact lists in less time - with U.S. phone support at +1 (646) 760-7250 Monday through Friday, 9 AM - 5 PM ET.

Records export directly to Excel, CSV, and SQL formats with U.S.-friendly column structure: separate first name, last name, street address, city, state abbreviation, ZIP code, phone numbers, business website, and available email. That means less time reformatting and more time prospecting, dialing, or analyzing.

Our story

IQUALIF was originally developed for marketing professionals on a PHP client-server architecture. The move to a commercial product required a full overhaul and a new approach: a multi-platform desktop application that runs on Windows, macOS, and Linux, with shorter development and maintenance cycles and higher availability for paying customers.

Our philosophy

Keep the product as easy to use as possible, and focus on the heart of the business: contact extraction. We are guided by Niklaus Wirth’s 1995 observation that “software development is slower than the accelerated development of hardware.” Computers get faster every year, but most software does not. User experience is too often used as a proxy for performance, and economic pressure pushes companies to ship new products at the expense of maintaining existing ones. We avoid that trap by constantly optimizing IQUALIF so paying customers can keep using the same tool, faster and cleaner, year after year.

Designed for U.S. go-to-market teams

IQUALIF is primarily used to feed U.S. call centers, sales-development teams, B2B agencies, recruiters, and small-business outreach campaigns. Beyond outbound dialing, the same exports power professional mailing, e-mailing campaigns, market sizing exercises, and territory planning.

IQUALIF automates data extraction from public yellow and white pages directories across more than 80 countries, including the United States, and exports complete data sets to Excel. Custom data-mining projects can also be scoped to other directory sources and online catalogs, depending on your team’s needs.

One software for the U.S. and international markets

The same software covers the United States and international markets:

• - U.S. individuals: extracts consumer contact information from public U.S. white pages directories for local B2C, residential, and community-outreach campaigns.
• - U.S. businesses: extracts business contact information - names, addresses, phones, websites, and available emails - from public U.S. yellow data pages directories for B2B prospecting.
• - Canada: cross-border lead lists for U.S. teams operating in or expanding to Canada.
• - United Kingdom, Australia, and Europe: the same software for international expansion (UK, Ireland, Australia, France, Germany, Spain, Italy, Belgium, Switzerland, Luxembourg, and more).

Our goal is to ship a simple, reliable, and effective tool that compounds your marketing and sales results. IQUALIF is engineered to boost output in both volume and efficiency.

40% more contacts than competing extractors

The volume of contacts extracted by IQUALIF is on average 40% higher than competing tools. For any U.S. team running prospecting, dialing, or research campaigns, that gap is a real productivity advantage. The difference comes from how IQUALIF queries multiple secondary directories and recovers cleanly from errors that would cause other extractors to drop records.

Our coverage of more than 80 countries gives us a wider view of how directories evolve, which helps us keep improving IQUALIF for U.S. teams. For any questions, use our contact form or call +1 (646) 760-7250.

Engineering

IQUALIF is built on Excel macros and core development in VBA, Access, PHP, Java, Python, C#, and C++. Owning each layer of the stack lets us control every stage of the IQUALIF lifecycle, from parsing logic to export formatting. The software works with business directories, registers and other sources from more than 80 countries, such as the United States, Canada, France, Belgium and Switzerland.

For qualification files built from yellow and white pages data, IQUALIF acts as a complete pipeline rather than a simple scraper: it pulls every record from B2B professional directories and B2C residential listings, with a capture rate roughly 40% higher than competing tools. We also offer automated enrichment, so file fields are completed either manually or automatically with high reliability.

Manual searching across directory websites is over. IQUALIF is not a single-site analyzer - it is a complete engine that speeds up B2B and B2C contact discovery and gives you exports you can take straight into your CRM, dialer, or spreadsheet workflow.

Responsible U.S. outreach

IQUALIF collects structured data from public directory sources. Your team retains full control over where data is used, and stays responsible for complying with U.S. outreach rules - including TCPA, CAN-SPAM, the National Do Not Call Registry, and state-level privacy frameworks such as CCPA/CPRA (California), VCDPA (Virginia), CPA (Colorado), CTDPA (Connecticut), and UCPA (Utah). IQUALIF includes deduplication and filtering tools so your compliance review happens on a clean file.
