The Central Violations Bureau is a national center responsible for processing violation notices (tickets) issued and payments received for many federal petty offenses cases. This includes violations that occur on federal property such as military installations, federal buildings, national parks, Veteran Affairs medical centers, national wildlife refuges, and national forests. The Central Violations Bureau processes violation notices for violations of federal law that occur outside federal property as well. For example, migratory bird offenses that occur on private property.
