About This Report
Fair Market Value compiles this NAICS 513140 industry report using data from the U.S. Census Bureau[5], the Bureau of Labor Statistics[6], and the Small Business Administration[7]. Our research team analyzes data licensing revenue models, directory advertising rates, and mailing list pricing structures to build valuation benchmarks specific to these publishing operations. This report on NAICS 513140 is updated quarterly to reflect evolving data privacy regulations and digital platform trends.
Industry Definition & Overview
Directory and Mailing List Publishers (NAICS 513140) encompasses establishments primarily engaged in publishing directories, mailing lists, and compilations of facts or data. Products include telephone directories, business directories, professional membership directories, mailing address lists, and compilations of legal case results, drug databases, or public records. These publishers may distribute their products in print or electronic form, including through online platforms and downloadable databases.
The industry has undergone a structural shift from print to digital delivery. Printed telephone directories and yellow pages, once the dominant revenue driver, have declined sharply as consumers and businesses migrated to online search engines and digital business listing platforms. Surviving firms have pivoted to data licensing, digital directory platforms, and targeted mailing list products that serve direct mail marketers, political campaigns, market researchers, and sales teams. Roughly 677 establishments remained active in recent industry counts.
Mailing list compilation involves collecting, verifying, and enriching contact data from public records, surveys, subscription lists, and third-party sources. Data quality measures such as deduplication, address standardization, and demographic appending add value that commands premium pricing. The Census Bureau[3] tracks publishing industry revenue, while the Federal Trade Commission[4] regulates commercial data practices that affect how mailing list publishers collect and sell consumer information. Geographic concentration follows population density, with the largest operations based in major metro areas where data volume and client demand are highest.
