Hello. There are 2 types of dead fullz:
1 - the cardholder has changed their residential address, surname or other personal data and now it does not fit in your services.
2 - fullz was used in a specific service and does not climb there anymore. In this case, we can use fullz in other services and sites.
For example, it is not possible to register a bank account according to fulls. Depending on the bank's response, we can try to register a bank account in another bank and it will be registered successfully.
