Providing your Employer Identification Number (EIN) or Social Security Number (SSN) is required for customs clearance to ensure proper identification and verification of the importer or consignee. This information helps U.S. Customs and Border Protection (CBP) process your shipment and ensures compliance with customs regulations. Without this information, your shipment may be delayed, held, or returned by customs authorities. Please be assured that your EIN or SSN is kept confidential and is only used for the purpose of customs processing.
