Establish an independent contact route
Start with the operator identity and a contact route established independently of the offer under review. Confirm the legal entity, terminal and person responsible for the proposed service.
Ask the issuer
Where obtainable, ask the actual issuing organisation to confirm relevant documents or claims. A document forwarded through a chain of intermediaries is not independent confirmation of the underlying arrangement.
Understand what was established
Report exactly which checks were completed. A confirmed company identity does not establish that a particular person has authority or that capacity is reserved for your transaction.
