ContainerHelper is a directory and research resource for businesses moving container freight in the United States and Canada. It helps users find freight forwarders, customs brokers, NVOCCs, drayage and container trucking companies, 3PL warehouses, fulfillment providers, and other freight-related organizations by service and location. Users can search by city, company, or registration number, explore listings by state or province, and browse providers near ports and inland hubs.

The directory presents public-record information from sources including the Federal Maritime Commission, U.S. Customs and Border Protection, and the Federal Motor Carrier Safety Administration. It also draws warehouse-service details from trade-association directories and company websites. Company profiles identify source dates and distinguish registered information from company-submitted details. ContainerHelper offers practical guides and checklists for tasks such as arranging port pickups, preparing customs documents, and verifying providers before booking. It also provides tools to save contacts, request provider introductions, and claim or correct a listing. ContainerHelper supports provider research; it does not arrange transportation or clear customs.
