during the 1890s, mails destined for foreign destinations was collected at Kabul, carried by relay courier post services to Peshawar, British India (now in North-west frontier Province, Pakistan), where Afghanistan maintained a treaty post office. The sealed mail bags were sorted at the post office (often removing the stamps for sale to philatelists), with Peshawar destined mails kept for local deliveries. Afghanistan was not a U.P.U. member at this time, its postage stamps were without international postal validity; mails destined for other parts of British India or foreign destinations was franked with the stamps of India, then deposited with the India post office. Incoming mails entering the Peshawar Postal Agency for delivery in Afghanistan was forwarded to Kabul with Afghan stamps affixed, or with postage due notations.
