Early posts The first posts in Yemen were part of the
Ottoman Empire postal system. After the Ottomans withdrew from Yemen there was no formal postal service, as far as is known, until the first issue of Yemeni stamps in 1926. International mail required additional stamps to be added from a country that was a member of the
Universal Postal Union as Yemen did not join the UPU until 1 January 1930. International mail was often routed via
Aden on the Yemeni coast which was under British control at the time. Stamps of
British India, as used in Aden, were added and mail cancelled ADEN CAMP. After joining the UPU, Yemen issued a new series of definitive stamps in accordance with UPU regulations.
Early intaglio seals 1926–1930 Locally produced intaglio seals were used to cancel domestic mail franked by the first issue of Yemen in 1926. All of the First Issue Stamps of Yemen are cancelled with intaglio seals. Neither Ottoman nor German bilingual postmarks are found as principal cancel of the first issue. The intaglio cancels on the first issue vary in diameter from 20 to 31mm; the smaller, less elaborate ones tend to have been used earlier and vice versa. None are found with later 35mm intaglio cancels. McDonald states 99%+ of the many hundreds he encountered were cancelled by either Sanaa or Hodeida postmarks whereas there were potentially 30 post offices where a canceller could have been used as this is the total on the list submitted to the UPU in Yemen's application to join in 1930.
Printed matter Mail to foreign destinations required additional postage as Yemen was not yet a member of the UPU. With printed matter i.e. the Umm al Qura newspaper and the government gazette Al Iman to foreign destinations including Cairo, Damascus and Beirut the additional franking was usually the one Anna adhesives, though also found without additional franking. Syrians worked in Yemen in Government service.
Letters to Italy and its colony Eritrea Mail to Italy was generated as a treaty of trade and commerce was secured and with it Italian personnel including doctors arrived in Yemen.
Civil war During the
North Yemen Civil War from 1962 to 1970, stamps were issued by both the
Mutawakkilite Kingdom of Yemen and the
Yemen Arab Republic. By 1968, the republicans had essentially won the war. The royalists issues continued until 1970. == South Yemen ==
