Feinsearch Unspecified API - Developers

The service provides lookup access to a database of employer identification numbers (EINs) and related information for over 16 million suppliers doing business with U.S. companies. It allows for verification of tax reporting accounts for vendors, contractors, and suppliers to allow compliance with payment reporting requirements. Search options allow either individual or batch lookup to retrieve EIN values or verify those supplied by vendors. API methods support search against a database of tax-paying companies with returned data specifying EIN or Tax ID number, primary industry SIC code, phone and fax numbers, and verified addresses. The API also provides operating information like the year the company started, its employee head-count, and estimates of sales and revenue.
