The OpenPostcode is already implemented in a number of different ways in Ireland and around the world.
- It is used to communicate locations in emails and text messages.
- It is currently used in backoffice systems for customer databases in proprietary systems (quite legal and free under the LGPL).
- It can also be immediately used on addresses and envelopes.
- It is the basis for an Arabic implementation as the new national postcode of Yemen. mefso.org
