Vat registration is fast and easy.
A sole trader will get the same registration number as his ID. A company or a registered entity the same number as the registration number of the entity. In order to register you need a bank account and fill in a simple document.
Separate businesses can under some situations get one VAT registration number and act as they are one business.
Foreign entities who want to register must nominate an Israeli fiscal representative that can be either a person or an entity that conducts business in Israel.
