Delaware Seller Identification, also known as a Delaware Seller’s Permit, is a business registration required by the Delaware Division of Revenue. This registration is required for any businesses that sell tangible personal property, services, or digital goods in the state of Delaware and are subject to Delaware’s sales and use tax. There are two types of Delaware Seller Identification: a general license, and a general license with a transient seller permit. The general license is for businesses that are physically located in Delaware, while the transient seller permit is for businesses that make sales in Delaware, but are not located in the state. A Delaware Seller Identification is necessary for any businesses looking to do business in Delaware and is a prerequisite for obtaining a Delaware business license.
