What number should be on your website and your van? A local landline, an 1800 freephone, an 0818, a mobile? Each says something different to the person about to ring you, and costs behave differently too. Here’s the plain-English tour of Irish business numbering, and how to choose.
Geographic numbers: 01, 044, 09x and friends
These are the classic area-code numbers — 01 for Dublin, 044 for Mullingar, and so on. For most businesses they remain the best default: familiar, trusted, and a quiet signal that you’re local — which matters when a customer wants someone who can actually call out. Two modern facts worth knowing:
- They’re no longer tied to the wires. On a VoIP system a geographic number rings wherever you are — office, mobile, home. Moving premises doesn’t mean a new number (see moving office without losing your number).
- You can hold numbers for areas you serve. A business covering several counties can present a local number in each — all landing on the same system.
1800: freephone
Free for the caller; the business pays for the call instead. The classic choice when you want zero barrier to ringing — support lines, bookings, campaigns. The trade-off is simply cost ownership: you’re picking up the tab to make it easy for customers.
0818: the “national” number
0818 gives one non-geographic number for the whole country — callers pay roughly the same as calling a landline (it’s typically included in call bundles). It replaced the older 1890/1850/076 ranges, which have been retired — if your signage still shows one of those, it’s overdue an update. 0818 suits organisations that don’t want to look tied to one county; the flip side is it feels institutional rather than local.
Mobile numbers as the business line
Common for sole traders, and everyone understands it — but it has real costs: it looks small, it follows one person (holidays included), and if that person leaves, the number often leaves with them. The modern middle ground: keep a proper business number front-of-house and ring it through to mobiles via the system — professional outside, flexible inside. (More in small business phone systems.)
So which should you choose?
- Local trades, shops, practices, most SMEs → a geographic number, presented everywhere, ported onto a modern system so it rings wherever you are.
- Nationwide service businesses → 0818 (or 1800 if you want callers to pay nothing), often alongside local numbers for key areas.
- Campaigns and support lines → 1800, where removing every barrier to calling is the point.
- Everyone → whatever you choose, put it on one system with proper call handling behind it — the number is the front door; the routing is the building.
Frequently asked questions
Can I keep my existing number whatever I do?
Almost always yes — geographic and non-geographic numbers alike can be ported to a modern system. Never cancel the old line before the port completes.
Can one business have several numbers?
Yes, and it’s common — e.g. a local 044 plus an 1800 for bookings, both ringing the same phones with different greetings if you like.
Are 0818 numbers expensive for callers?
They’re charged like national landline calls and are typically included in bundle minutes — the old “premium rate” reputation belongs to ranges that no longer exist.
