The ring can be returned to have the number changed as the bowler rolls additional perfect games. The United States Bowling Congress (USBC) offers a 'multiple' 300 ring for an additional fee that features the number of approved 300 games for that bowler surrounded by stones. Subsequent league 300s are denoted by setting 'chips' or precious stones into the ring, so that skilled bowlers do not have to wear several rings. In league or tournament play, a certified 300 game is usually commemorated with a ring. The lanes are inspected once a year, and the ball's make and serial number (USBC only requires that the ball have an engraved serial number, they do not need the actual number) are taken by a league/tournament official and reported to the certifying organization. Modern recognition is much easier lanes are no longer shut down, balls are no longer taken and inspected. However, the score still counts towards the league or tournament statistics. There are cases where the tests do not meet regulation, and therefore the score is not recognized by the organization. The data was then sent to the certifying body, and the score received a certification decision a few days to a few weeks later. The official then used a tape reader to test the oil condition, to make sure it met the organization's regulations. Also, the lanes used in the scoring were shut down after the last game of the day was completed.

In earlier years, the bowling ball(s) used in the scoring was taken for testing (hardness, weighting, and other aspects that would otherwise break the organization's regulations). First, the bowler and league (or tournament) must be in good standing with the organization.
