What is the exporter's identification number known as for a corporation in the U.S.?

The exporter's identification number for a corporation in the U.S. is known as the Employer Identification Number (EIN). This unique number, issued by the Internal Revenue Service (IRS), serves multiple purposes, including identifying businesses for tax purposes and facilitating various administrative processes related to business operations, including exporting.

In the context of export activities, the EIN is often required when completing export documentation, as it helps the government track trade statistics and enforce compliance with export regulations. The use of the EIN as an identification number simplifies interactions with various governmental agencies, ensuring that all business activities are properly accounted for under U.S. law.

While a business registration number is also important for establishing legality in business practices, it does not serve the same multifaceted purpose as the EIN. The export license number refers specifically to licenses required for certain goods and is not a universal identifier for all exporters. The Customs Broker Identification Number relates to customs brokers specifically, not the exporting corporation itself. Thus, the EIN stands out as the correct choice for a corporation's identification in export transactions.
