50 CFR 80.33 – How does an agency decide who to count as paid license holders in the annual certification?
(a) A State fish and wildlife agency must count only those people who have a license issued:
(1) In the license holder’s name; or
(2) With a unique identifier that is traceable to the license holder, who must be verifiable in State records.
(b) A State fish and wildlife agency must count a person holding a single-year license only once in the certification period in which the license first becomes valid. (Single-year licenses are valid for any length of time less than 2 years.)
(c) A person is counted as a valid license holder even if the person is not required to have a paid license or is unable to hunt or fish.
(d) A person having more than one valid hunting license is counted only once each certification period as a hunter. A person having more than one valid fishing license is counted only once each certification period as an angler. A person having both a valid hunting license and a valid fishing license, or a valid combination hunting/fishing license, may be counted once each certification period as a hunter and once each certification period as an angler. The license holder may have voluntarily obtained them or was required to have them in order to obtain a different privilege.
(e) A person who has a license that allows the license holder only to trap animals or only to engage in commercial fishing or other commercial activities must not be counted.
