The village Post Office, opened c. 1845, was closed in April 1924. A separate office had been opened at Straffan Station in May 1872, this adjacent to the former Station, 1.5 mi (2.5 km) from the village. On the adoption of Irish language names by the Irish Post Office in 1922 the name of Cluainíní was adopted for the Station office, this being the Irish version of Clownings, the townland in which the Post Office and former station were situated. That office was closed c. 1977 at which date the office in the village was reopened and the Irish name of Teach Srafáin was adopted, this name appearing in the 1982 Post Office Guide.
