Q-12. What is CCR and SUB-Net?
CCR – Central Contractor Registration (Formerly Pro-net) is an online database of information on thousands of small businesses and serves as a search engine for contracting officers, a marketing tool for small companies, and a "link" to procurement opportunities and other important information. It also provides links to the online Commerce Business Daily, federal agency home pages and other sources of procurement opportunities. It offers free registration to small businesses. Simply access the CCR web site at
and follow the instructions. Trouble calls or problems with logins should be addressed to (202) 205-7312/7325 or Fax 202 205-7324.

SUB-Net, an extension of PRO-Net, is primarily for prime contractors to post subcontracting opportunities. These opportunities may or may not be reserved for small businesses. They may include solicitations or other notices, such as a search for "teaming" partners and/or subcontractors for future contracts. The SUB-Net site enables small businesses to use their limited resources to identify and bid on concrete, tangible opportunities. While the web site is designed primarily as a place for large businesses to post solicitations and notices, federal agencies, state and local governments, nonprofit organizations, colleges and universities, and small businesses can also use it for the same purpose. You can access SUB-Net through the PRO-Net home page by choosing the "Subcontracting Opportunities" button. Or, you can go directly to SUB-Net at
