Why?

ComReg manages and administers the National Numbering Scheme in order to ensure that adequate reserves of telephone numbers exist for all new customers and services. The Numbering Plan for Ireland lists all numbers and codes that are available on public telecommunications networks. These include ordinary PSTN/ISDN telephone numbers linked to your home or business phone (geographic numbers), free phone, premium rate and internet access codes (non-geographic numbers) and mobile numbers.

When the level of “free” numbers (i.e. the quantity of numbers that are available for allocation) reaches a certain level, changes to the numbering scheme are necessary to ensure that sufficient numbers are available to all authorised entities, and subsequently to end-users.

That level has now been reached in the following STD codes: 023, 043, 052 and 064. Number changes are therefore necessary in these areas.

Consumers should contact their telecommunications service provider in the first instance for more information on these changes.

Parallel Running

Parallel working is the period of time when it is possible to use both the old and new numbers. Parallel working for this set of number changes will be operational from the beginning of November 2008. A six month period is then allowed to ensure that all users are informed of the number changes. Parallel working will cease (i.e. only the new number will be operational) in stages from May 2009.

The dates for parallel running will be as follows:

New STD Area Code Start Date Number Changeover Date
023 3rd November 2008 8th May 2009
043  3rd November 2008 22nd May 2009
052  3rd November 2008 5th June 2009
064 3rd November 2008 19th June 2009

From the start dates, either the old or new numbers may be used by callers until the end date shown above.

These public cessation dates (NUMBER CHANGE DATES) represent the earliest dates from which the old numbers should be considered inoperative, although some old numbers may remain operative for a short period after these respective dates.

Recorded Announcements

After the cessation of parallel running, calls to the old Subscriber Numbers will be routed to recorded announcements which will prompt the caller with the prefix to be inserted before the old 5 digit Subscriber Number. Calls to old numbers should be routed to recorded announcements for a period of at least 12 months after the number changes.

Directories

Since the telephone directories for any given year are distributed in the previous autumn (e.g. the directories for 2009 will be distributed in the autumn of 2008), the new 7-digit numbers will first appear in telephone directories for 2010. These will be distributed to homes in the autumn of 2009. Anyone who contacts any of the directory enquiry services from the relevant cut-over date in May or June 2006 will be informed of the new 7-digit number and not the old 5-digit number.
