However, there are sections where ICOCA is not accepted even though trains arrive regularly from the Keihanshin Urban Network area (for example: Tsuruga Station, the section to the north of Shimoyamaguchi Station on the Fukuchiyama Line, and the section between Takada Station and Wakayama Station on the Wakayama Line).
一方、京阪神エリアのうちアーバンネットワーク内から定期列車が乗り入れるにもかかわらず、ICOCAが利用できない線区（例：敦賀駅、福知山線の篠山口駅以北、和歌山線の高田～和歌山間など）がある。
