Postage Stamps of Ireland

The postage stamps of Ireland are issued by the postal operator of the independent Irish state. Ireland was part of the United Kingdom of Great Britain and Ireland when the world's first postage stamps were issued in 1840. These stamps, and all subsequent British issues, were used in Ireland until the new Irish Government assumed power in 1922. Beginning on 17 February 1922, existing British stamps were overprinted with Irish text to provide some definitives until separate Irish issues became available. Following the overprints, a regular series of definitive stamps was produced by the new Department of Posts and Telegraphs, using domestic designs. These definitives were issued on 6 December 1922; the first was a 2d stamp, depicting a map of Ireland (including Northern Ireland, which remained a part of the United Kingdom). Since then new images, and additional values as needed, have produced of seven definitive series of different designs.

These were the major stamp productions for everyday use. Commemorative stamps first appeared in 1929, and these now appear several times a year, celebrating many aspects of Irish life, such as notable events and anniversaries, Irish life and culture, and many famous Irish people. Some definitive and commemorative stamps have been produced in miniature sheet, booklet and coil configurations in addition to the common sheet layout. Postage dues and airmails complete the stamp issues of the two, sequential, Irish stamp-issuing authorities. Two styles of watermark were used though the overprinted issues came with the watermarks of the British stamps provided for overprinting by the British Post Office.

Oifig an Phoist, the Irish Post Office, was the section of the Department of Posts and Telegraphs which issued all Irish stamps up to 1984. After the division of the Department of Posts and Telegraphs into two semi-state organisations in 1984, An Post took over the responsibility for all Irish postal services including the issuing of postage stamps.
