The first postal orders of Nigeria were issued by the British colonial authorities.
[1] Nigeria became independent from Britain on 1 October 1960 and after then began to issue postal orders in its own right denominated in Nigerian pounds, shillings, and pence, although records at the British Library indicate that these were at first supplied by Britain's Crown Agents.
A number of proof Nigerian postal orders dated 1964 and 1965 are contained in the Crown Agents Archive of the British Library Philatelic Collection.
[3] New postal orders were issued in 1973, when Nigeria changed over to the decimal currency of the Naira.
[4][5] In 1987, Nipost was charged with providing postal order services within Nigeria under Act No.
