How to read a number

+353871234567

+353Country code
Ireland.
87Mobile prefix
The national part of an Irish mobile number is 9 digits starting with 8; the first two digits are the prefix (83, 85, 86, 87, 89 and so on). Written nationally as 087…; that leading 0 is the trunk prefix and is dropped when dialling from abroad.
1234567Remaining 7 digits
The subscriber number. Ireland allows porting, so the digits do not tell you which operator the SIM is on now.

Written nationally as 087 123 4567.

Carriers & prefixes

Mobile prefixes by carrier.

Number portability applies — a prefix only shows the original carrier.

Porting rules in full

Porting is available and keeping your number is free (per the regulator ComReg). The new provider leads the switch, so you do not have to deal with the old one — but say explicitly that you want to keep your number, because you may not be asked. The switch should not be delayed without reason, and if something goes wrong you should not be without service for more than one working day; providers must pay compensation for loss of service, a delayed switch, a delay in closing the old service, or failing to keep you informed. Unlike the UAE, unused prepaid credit in Ireland can be refunded on request (a fair administration fee may be deducted). So Irish 08x prefixes only show who originally issued a number; we could not retrieve ComReg’s allocation table, and this site will not assemble one.

Network-experience stars are derived from the awards each operator won in the Opensignal report of 2026-01 (data collected Oct 01 - Dec 29, 2025): the most-awarded operator gets 5 stars, the rest proportionally, with a shared award counting as half. They reflect network testing only — not prices or customer service. Test report →

User share comes from ComReg (the telecom regulator), as of 2025-12. It shows how widely each operator is used — not how good its signal or service is. Official data →

SIM cards & keeping a number

Irish prepaid SIMs need no ID and are forgiving to keep: at Tesco Mobile, for example, the account is suspended only after 6 months without a top-up or chargeable use, can be restored for another 6 months, and the number is recycled after 13 months in total. Budget brands like 48 and GoMo are also popular.
