Licensing differs enormously zhí yè zī gé · 各国监管差异极大

There is no single global rule. In the United States most states license acupuncturists and the title is protected; national bodies administer examinations. In Australia, practitioners are registered under a national scheme. In the United Kingdom there is no single statutory regulator, and several voluntary registers operate.

The practical consequence: before booking, check your local health authority for how to verify credentials, and ask about needle hygiene, single-use needles and what training the practitioner holds.
