Who typically calls from this range?
0570 numbers are primarily inbound contact lines that you call, rather than numbers that call you. The caller pays, and Navi Dial calls are not covered by Japanese flat-rate calling plans (the Japan Pension Service, which uses 0570 lines, notes this explicitly). Treat unexpected incoming calls displaying 0570 with caution, including the possibility of caller ID spoofing.
Before you call back
You cannot reach 0570 Navi Dial numbers from international calls or most IP phones (per the Japan Pension Service FAQ). If you are outside Japan, use the regular geographic number (such as an 03 number) that most organizations list alongside their 0570 line.
