A Service-provider may also introduce other error codes not listed in this table. Such codes must not be within 0-99 range.

It is noteworthy that the BOG payment system does not guarantee to a service-provider that the text relevant
for the code sent by the latter (except for the values set forth by this document) shall be seen by all users.
Therefore, returning service-provider-generated codes is only recommended in exceptional cases.
