Alternate radio data frequency selection involves receiving radio data system signals and extracting region tables from the radio data system signals, with the region tables each including a quantity of alternate frequencies and a list of alternate frequencies. The quantity and list of alternate frequencies included in the region tables are compared with each other if the quantity of alternate frequencies included in a region table is equal to or greater than the quantity of frequencies included in another region table. One of the alternate frequencies included in the region table is identified if each of the alternate frequencies in the list of alternate frequencies included in each region table, and the identified alternate frequency is output if each of the alternate frequencies in the list of alternate frequencies is included in each region table. A seek operation is performed if any of the alternate frequencies in the list of alternate frequencies is not included in each region table.
