Ireland punches far above its size as a place to answer the phone. Dublin hosts the European headquarters of many of the world's largest software and internet companies, English is the working language of a eurozone economy, and the country acts as a natural bridge between the United States, the United Kingdom and the EU single market. A +353 number puts your business inside that conversation — Temptera delivers Irish geographic, national and freephone ranges straight into your SIP infrastructure, wherever your team actually sits.

Ireland numbering plan: prefixes and formats

Ireland's national numbering plan sits behind country code +353 and uses a trunk prefix of 0 for domestic dialling, with number lengths that vary by range. Geographic service is organised around area codes, from the single-digit Dublin code to three-digit regional codes covering the rest of the country.

  • Geographic: 01 for Dublin, 021 for Cork, 061 for Limerick and 091 for Galway. Dublin subscribers carry seven digits after the code, and the larger regional codes such as 021 also use seven-digit subscriber numbers.
  • Mobile: the prefixes 083, 085, 086, 087 and 089, each followed by a seven-digit subscriber number.
  • Freephone: 1800 followed by a six-digit subscriber number.
  • National non-geographic: 0818, which since January 2022 has been the single national range after ComReg retired the 1850 and 1890 LoCall codes and the 076 range.

For international callers the trunk zero disappears: a Dublin line written 01 followed by seven digits domestically is dialled as +353 1 from abroad, and an 087 mobile becomes +353 87. Temptera presents Irish numbers to your equipment in full E.164 form, so no per-country digit manipulation is needed on your switch.

Who regulates numbering in Ireland

Numbering in Ireland is administered by the Commission for Communications Regulation (ComReg). ComReg maintains the National Numbering Plan, decides which prefixes exist and what services they may carry, and allocates blocks within those ranges to authorised operators. Any Irish DID you order ultimately traces back to a ComReg allocation held by a licensed carrier.

ComReg also shapes how the plan evolves and what conditions follow a number after assignment. Its consolidation of non-geographic numbering — retiring 1850, 1890 and 076 in favour of a single 0818 range — is a recent example, and its rules on appropriate use and end-user registration determine what evidence a buyer must provide before certain Irish ranges can go live. Temptera's onboarding for +353 numbers is built around those expectations.

Documents and verification for Ireland numbers

Irish number ranges do not all carry the same paperwork. Geographic numbers such as Dublin 01 or Cork 021 are the most closely tied to place, so orders in those ranges can call for evidence of an address in Ireland — a utility bill, lease or comparable record — alongside photo identification of the person or signatory placing the order. National 0818 and 1800 freephone ranges centre instead on verifying the business itself and its intended use of the number.

Companies trading through an Irish entity can usually rely on their Companies Registration Office (CRO) record, while overseas businesses substitute the equivalent extract from their home registry. Because obligations differ between the geographic, 0818 and 1800 ranges, Temptera displays the precise checklist for the range you select at order time — specific to Ireland and to that number type, with nothing left to discover after purchase.

What businesses use Ireland numbers for

Demand for +353 numbers follows the shape of the Irish economy itself — a dense cluster of international headquarters, strong life-sciences regions and deep trading ties with the UK.

  • EMEA support operations anchored in Dublin. Technology and financial-services groups running their European operations from Ireland use Dublin 01 numbers to give customers and partners a recognisable local point of contact, even when the answering team is distributed across time zones.
  • Life-sciences and manufacturing in Cork and Galway. Pharmaceutical and medtech firms concentrated around 021 and 091 use regional geographic numbers for supplier coordination, site contact lines and product support desks.
  • UK businesses serving Irish customers. Retailers and service companies across the Irish Sea present an 0818 national number or an Irish geographic identity so customers in Ireland are not asked to dial a +44 number for local service.

How to get a Ireland number

  1. Create your Temptera workspace and select Ireland (+353) as the destination country.
  2. Choose the range that matches how Irish callers should see you: Dublin 01, a regional code such as 021 Cork, the 0818 national range or 1800 freephone.
  3. Upload the paperwork the order screen lists for that specific Irish range, such as identification, an Irish address record or a company registry extract.
  4. Let verification run; once the checks for that range clear, the number activates on your account.
  5. Direct the new +353 number to your SIP trunk or hosted PBX and place a test call from an Irish line to confirm routing.

Frequently asked questions

Can I get a Dublin 01 number without having an office in Dublin?

Dublin 01 numbers are geographic, so Irish rules can attach address-related conditions to them. In many cases a documented business connection to Ireland satisfies this, and a physical Dublin office is not always necessary. The exact evidence required for the 01 range appears at order time, and because Temptera delivers the calls over SIP, your team can answer a Dublin line from any location.

What replaced 1890 and 1850 numbers in Ireland?

ComReg withdrew Ireland's 1850 and 1890 LoCall ranges, together with the 076 range, at the start of 2022. The 0818 range is now the single national non-geographic prefix, sitting alongside 1800 freephone. Organisations still publishing 1890 or 1850 contact points on stationery or packaging should migrate those lines to an 0818 number, which is reachable from Irish fixed and mobile networks alike.

How do international callers dial an Irish virtual number?

Ireland uses country code +353 with a trunk prefix of 0 that is dropped when dialling from abroad. A Dublin number written 01 followed by seven digits domestically becomes +353 1 plus those digits internationally, and an 087 mobile becomes +353 87. Temptera hands the full E.164 form of every Irish number to your SIP equipment, so no local rewriting rules are needed on your side.

Can I keep my existing Irish number and move it to Temptera?

Number portability between authorised operators is an established part of the Irish market, covering geographic, mobile and non-geographic ranges. Whether a specific number can move depends on its range and its current holder, so Temptera confirms feasibility when you raise the porting request. Once ported, the number behaves like any other Irish DID on the platform, routed to your SIP infrastructure.

Do Ireland virtual numbers work with Microsoft Teams or a cloud PBX?

Yes. Temptera hands Irish inbound calls to you as standard SIP traffic, which Microsoft Teams via direct routing, a hosted PBX or an open-source platform such as FreeSWITCH or Asterisk can accept. Presenting your +353 caller ID outbound from those platforms is also supported where the Irish range permits it, so a Dublin 01 or 0818 identity stays consistent in both directions.
