Bib number (plural bib codes) A bib number is used to identify race participants. It is a nine-digit alphanumeric code assigned at the time a participant registers to enter a race. The first three digits are reserved for the site where the race is being held; the next three for the type of event, either individual or team; and the last three for the specific participant. For example, a female entering an individual race would receive a four-digit entry code. The bib number is useful for tracking race results and identifying any discrepancies when reviewing finish times. Participants are required by law to wear a form of identification during all races, including the Olympic Games. This includes wearing a bib number during race events. Race organizers may choose to require bib numbers for their own safety purposes. For example, they may want to ensure that no one enters multiple races using the same identity information or equipment violations. The bib number is also important for determining prize money for winners. Prizes are allocated according to the order in which people register for a race with the exception of team events where each member of the team receives equal credit for their participation.
