Card1Card is an international service aggregator that connects customers with specialist providers and partners across multiple countries. It offers a single point of contact for exploring professional services, submitting inquiries, and checking the status of orders. Each accepted order receives a reference number, and customers can use the website’s online checker to verify an order using their client and order numbers. The service states that this check does not reveal personal or payment information and that the numbers are not retained by the site for that purpose.

Its partner network covers international payments and digital-asset transactions; overseas accounts and cards; US company formation and banking; US immigration law; international insurance; legal services in Russia; conscription and mobilization law; residence permits and international immigration; software development and automation; forensic examinations; and personal assistance worldwide. Services may include comparing requirements, preparing documents, navigating consultations, and coordinating local tasks. Card1Card identifies itself as an aggregator, noting that the independent partner named in a specific offer or order provides the service.
