Editing Subscriber trunk dialling (section)

====From the Republic of Ireland====
Calls to Northern Ireland were made by dialling 08 and the Northern Irish STD code, for example Belfast was reached by dialling 08 0232.

Calls to Britain were made by dialling 03 and the British STD code, e.g. 03 0222 XXX XXX or 03 061 XXX YYYY.

Calls to cities with director area codes could also still be made with the following codes; this was an older arrangement but the numbering remained in service until the 03 code was closed:

*031 London
*032 Birmingham
*033 Edinburgh
*034 Glasgow
*035 Liverpool
*036 Manchester
*Calls to Belfast could also be dialled with 084 and the local six-digit number. Belfast was not a director area.

In 1992, Ireland adopted the harmonised European international access code 00, replacing the 16 prefix for international calls and the legacy arrangements for calling Britain. From that year, calls were made in the standard international format, i.e. {{gaps|00|44}}, and the 03 range was withdrawn from use.

Calls to Northern Ireland are now made by dialling 048 and the eight-digit local number, omitting the 028 STD code. This ensures calls are charged at lower rates. Alternatively, the full international code +44 28 can be used.
