Yes. Any bank can inform a person (or their representative) if their name is on the list and, if so, when it was added to it. Only the bank of the drawer is in a position to inform that person (or their representative) about the number and amount of the cheques in question.

Considering bank secrecy rules in force in Portugal, the Banco de Portugal may provide the content of the existing registers in its database to the data subject (or those empowered to represent them):

• through the Internet, on the Banco de Portugal’s website - https://www.bportugal.pt/area-cidadao/formulario/240; 
• in person, at any of the Banco de Portugal’s information desks; 
• in writing to the address indicated by the entity.

This information includes: the ID of the person (natural or legal), banks or courts that have submitted information on their behalf, the date and type of reported event, date of entering/exiting the list.
