Publishers Clearing House primarily operates within the United States. The company is best known for its sweepstakes and prize giveaways, which are predominantly open to residents of the U.S. However, there may be certain exceptions for specific promotions that include international participation, but these are not the norm. It is always a good idea for individuals outside the U.S. to check the official PCH website for the specific rules and eligibility for any ongoing promotions or contests. The website regularly updates information on how and when individuals can enter sweepstakes and details about any international offers that may be available.
