Find the business address of an online company from the company's website, state business filings or third-party search tools, such as the Better Business Bureau. Third-party marketplaces that sell a company's products may also make the company's business address available.
Online companies that send any form of email regarding products or services are required by federal anti-spam laws to provide customers with a business address. This includes solicited email and business-to-business email. Businesses that do not send email are not required by federal law to provide an address, but more restrictive state laws may require them to do so.
A legal business address does not have to be a physical address that customers can visit. Federal law states that post office boxes, private mailboxes and mail-receiving agencies are acceptable forms of business addresses. The only requirement is that the business address must be a valid postal address where customers can send mail.
The Federal Trade Commission does not recommend doing business with any online company that does not provide a business address, even in cases where one is not required. The agency recommends confirming the company's business address and telephone number before completing any transaction. Confirming this information helps filter out fraudulent companies.
