From the 1930s, a rubber date stamp was produced in a range of shapes and sizes with the inscription Post & Telegraph Office or just Post & Telegraph. The date stamps listed on this page are the known rubber date stamps headed with either of these inscriptions.
See elsewhere for other inscriptions on rubber or steel date stamps.
All date stamps below are rubber unless otherwise indicated.
The shape of the date stamps varies from circular (RC) to oval (RO) to rectangular (RR).
