The first Curacao meters came into use in 1938. Curacao was a colony of the Netherlands until 1954 when it joined with other Dutch territories in the Caribbean to form the Netherlands Antilles. See NETHERLANDS ANTILLES for issues between 1954 and 2010.
On 10 October 2010 (10.10.10) the Netherlands Antilles dissolved with the various islands going in different political directions. Curacao and St. Maarten formed a unit that, although still attached to The Netherlands, has greater self government. Since the change stamps have appeared inscribed CURACAO alone, NIEUWE POST, and C-POST. Stamps inscribed St. Maarten alone have not been reported.
The stamps are grouped according to period and usage:
A – Colonial era stamps from machines in private, commercial use
B - Semi-independent era stamps from machines in private, commercial use
PO – Stamps from machines in Post Offices
Group A: Colonial era stamp generated by machines in private, commercial use
