| Comments: | The Seistan Arbitration Commission operated between 1903 and 1905 with the purpose to demarcate the boundary between Persia and Afghanistan in the vicinity of Seistan. A postal unit served the commission and used a date-stamp inscribed Camp P.O. No. 4.<br /> <br /> Mail is rare. <br /> <br /> The exact date that the post office was opened and closed is not known so the opening and closing date is based on the dates of recorded mail. |
