The USGA® recommends that a hole-in-one be considered valid:

1. If made during a round of at least nine holes, except that a hole-in-one made during a match should be acceptable even if the match ends before the stipulated round is completed.
2. If the player is playing one ball; a hole-in-one made in a practice round in which the player is playing two or more balls should not be acceptable.
3. If attested by someone acceptable to the Committee.
4. If made at a hole with a temporary tee and/or putting green in use, even if the Committee did not specifically define the teeing ground with tee-markers; the length of the hole at the time should be stated on any certificate.

The USGA does not provide a registry for hole-in-ones, but you can register your Hole-In-One at the PGA or at United States Golf Register.
