OTCBB stands for Over The Counter Bulletin Board. This is a system for OTC equity securities that are not listed on the NASDAQ. Brokers have to subscribe to this non-electronic system and can then use it to enter orders for OTC securities.
The OTCBB symbol for a company is a unique identifier used for trading its stock on the Over-the-Counter Bulletin Board.
When a company wishes to "uplist" from otcbb or pinksheets to Nasdaq it must first file S-1 and S-1a until final approval. Once final approval is obtained the SEC files a CERTNAS.
