The employer identification number (EIN) is assigned to business entities and is the primary taxpayer identification number in the United States. This number must be obtained when starting a business in the United States. Without it, it is impossible to open a bank account in the USA for business.
EIN makes it possible to carry out commercial activities in the USA, as well as on all electronic platforms and merchant accounts, such as PayPal, Beatport, Stripe, etc.
EIN is issued once and has no usage restrictions.
