}Notes
- Source: Seino's public tracking page (Shift_JIS HTML). Ten digits (also written
123-456-7890) is shared with other carriers, so use?carrier=seino. - Time zone: Japan keeps one zone (
Asia/Tokyo). Seino prints only the day of the month, so the month and year are worked out from the acceptance date. - Retention: Seino drops numbers about two months after delivery (
not_found). Descriptions are Seino's Japanese step names (受付 accepted, 発送 dispatched, 中継 relayed, 到着 arrived, 持出 out for delivery, 配達 delivered).
