OTC Bulletin Board (OTCBB)

The OTC Bulletin Board (OTCBB) is an electronic quotation system that displays real-time quotes, last-sale prices, and volume information for many over-the-counter securities that are not listed on The Nasdaq Stock Market or a national securities exchange. Brokers who subscribe to the system can use the OTCBB to look up prices or enter quotes for OTC securities. Although the National Association of Securities Dealers, Inc. oversees the OTCBB, the OTCBB is not part of The Nasdaq Stock Market. Fraudsters often claim that an OTCBB company is a Nasdaq company to mislead investors into thinking that the company is bigger than it actually is.

Under the OTCBB's eligibility rule, companies that want to have their securities quoted on the OTCBB must file current financial reports with the SEC or with their banking or insurance regulators.
