A messaging system, having a transmitter (202) for transmitting information service messages to selective call units (SCU's) (122), receives displayable information from a service provider, and creates a message having an address field (504) and data field (508). The address field (504) includes an address assigned to at least one SCU (122), and the data field (508) includes the displayable information. A portion of the displayable information is defined as at least one subaddress field (510, 514). The at least one subaddress field (510, 514) is used by the at least one SCU (122), when receiving the message from the messaging system, for determining whether a portion of the displayable information is to be processed.
