Quick answer
+353 is the international dialling code for the Republic of Ireland. Plenty of +353 calls into the UK are genuine - Irish businesses, couriers, recruiters and people you know. A +353 number that rings once and stops is a classic one-ring (Wangiri) bait: do not ring it back. Northern Ireland is +44 28, not +353. You cannot get the caller's name from the number alone.
What a +353 number looks like
+353 is the country code for the Republic of Ireland. A full Irish number written internationally looks like `+353 1 234 5678` (Dublin) or `+353 87 123 4567` (an Irish mobile). The `+353` replaces the leading `0` that an Irish person would dial domestically - so the Dublin landline they'd dial as `01 234 5678` reaches you as `+353 1 234 5678`.
00353 is the same code. On a landline you dial 00 then the country code; on a mobile the + does that job. A missed call showing 00353 87… is an Irish mobile, not a different country.
A couple of points that trip people up:
- Northern Ireland is part of the UK, so its numbers use +44 28, not +353. A +353 call is specifically from the Republic.
- An Irish mobile starts +353 8. An Irish landline starts with the area code after +353.
| Domestic Irish number | What you see | Type |
|---|---|---|
| 083, 085, 086, 087, 089 | +353 83 / 85 / 86 / 87 / 089 | Mobile (Three, Eir, Virgin, Vodafone and others) |
| 01 | +353 1 | Dublin landline |
| 021 | +353 21 | Cork |
| 061 | +353 61 | Limerick |
| 091 | +353 91 | Galway |
| 051 | +353 51 | Waterford |
| 041 | +353 41 | Drogheda / north-east |
"087 phone number country" is Ireland - 087 is an Irish mobile prefix, written +353 87 from the UK. It is not a UK 07 mobile.
ComReg, Ireland's communications regulator, publishes the Irish numbering plan. The prefixes above come from that plan; they tell you the type of number, not who holds it.
Our free phone number checker is built around UK numbering, so for an international number the most useful first step is recognising the +353 code and treating the call on its merits.
Who genuinely calls from an Irish number
There are many perfectly ordinary reasons to see a +353 call in the UK. The Republic is next door, and the ONS long-term international migration figures have shown a large, settled Irish-born population in England, Scotland and Wales for decades - plus a constant flow of work, study and family visits in both directions.
Typical genuine callers:
- Irish businesses and shared-service centres. Plenty of international companies run customer-service, finance or sales operations from Dublin, Cork or Galway and dial UK customers from Irish numbers.
- Couriers, airlines and ferry operators confirming a delivery, booking or sailing.
- Recruiters and remote employers based in the Republic.
- Friends, family or colleagues living, working or travelling in Ireland.
- Hospitals, universities and public bodies in the Republic following up an appointment, application or bill.
So a +353 call can easily be genuine. The question is whether you were expecting contact from Ireland, and whether the call behaves like a real one (a voicemail, a follow-up, a reason that makes sense).
The one-ring (Wangiri) trap
The scam to watch for with international numbers is the one-ring, or "Wangiri", call: your phone rings once and cuts off before you can answer, leaving a tempting missed call. Ring it back and you may be connected to an expensive premium or international line that earns the scammer money while a recording keeps you holding. The same trick is used with various country codes - we cover it in detail in the one-ring missed-call (Wangiri) scam guide and more broadly in international scam phone calls.
Ofcom has warned repeatedly about international missed-call scams aimed at UK consumers. Action Fraud and Which? give the same advice: do not return a number that rang once and stopped. ComReg publishes consumer guidance on nuisance calls in Ireland; the pattern is the same on both sides of the Irish Sea.
The rule is simple: don't ring back a number that called once and hung up, Irish or otherwise. A genuine caller with a real reason will try again or leave a message.
What ringing back a +353 number costs
A callback to Ireland is an international call. It is almost never included in your UK mobile minutes.
EE's published standard rate to Ireland, checked on 8 September 2026 at ee.co.uk/help/mobile/roaming/call-abroad/countries/ireland, is 25p a minute to Irish mobiles and landlines (6p a text). EE also sells an International Pass that cuts that rate; without it, you pay the standard figure.
O2, Vodafone and Three each publish their own international price guides. We are not guessing those figures here - check the guide for your network before you dial, because a five-minute callback you did not need is a bill shock for no reason. A one-ring scam that connects you to a premium or unusual international route can cost far more than the standard Ireland rate.
Landline callbacks to Ireland are usually cheaper than mobile ones but are still charged as international, not as a 01/02 UK call.
WhatsApp calls from a +353 number
A WhatsApp call or video from +353 is just someone whose WhatsApp account is registered to an Irish number. That can be a friend in Dublin, or a stranger using the "wrong number" opener that investment and romance scams favour.
WhatsApp itself does not prove the caller is in Ireland - only that the account is tied to an Irish number. Use WhatsApp's "Silence unknown callers" setting (Settings → Privacy) so only people in your contacts can ring you, and never send money, codes or photos because a WhatsApp caller asked.
How to handle a +353 call
- Were you expecting it? A delivery, a job, a call from someone in Ireland? Context answers most of these.
- Let it go to voicemail if you're unsure. A real caller usually leaves a message; a one-ring scam never will.
- Don't call back a missed one-ring call. If you must return a call, search the full number online first for reports.
- Never share PINs, passwords, one-time codes or bank details on an inbound call, and never move money because a caller pressured you to.
- Block and report anything that's clearly a nuisance or scam - forward scam texts to 7726 and report a scam number to Action Fraud.
- On iPhone: swipe the call in Recents → Info → Block this Caller. On Android: tap the number in Recents → Block. On a landline, ask your provider for number blocking or anonymous-call rejection.
The bottom line
A +353 call is simply a call from the Republic of Ireland, and it's often genuine - an Irish business, courier or someone you know. The danger isn't picking up; it's ringing back a number that rang once and stopped, which is the hallmark of a one-ring scam. Check whether you were expecting an Irish call, let unknown ones go to voicemail, and never return a missed one-ring call. For the same checks on UK calls, see our guide to who called me.
Frequently asked questions
What does a +353 number mean?
+353 is the international dialling code for the Republic of Ireland. A call showing +353 is coming from Ireland - the +353 simply replaces the leading 0 of the domestic Irish number. Northern Ireland is part of the UK and uses +44 28, not +353.
Who called me from an Irish number?
It could be an Irish business, courier, recruiter or someone you know in Ireland - many genuine calls come from +353. You can't get the caller's name from the number alone, so check whether you were expecting an Irish call, let it go to voicemail if unsure, and search the full number online for reports before ringing back.
Should I call back a missed call from a +353 number?
Not if it rang once and hung up - that's the classic one-ring (Wangiri) pattern designed to make you call back an expensive line. If a +353 caller genuinely needs you, they'll leave a voicemail or try again. Only return a call you can see a clear reason for.
Are +353 calls always scams?
No. Plenty of legitimate calls come from Ireland. Treat a +353 call with the same caution as any unknown number: don't act on pressure, never share security details on an inbound call, and don't ring back a one-ring missed call.
Is 00353 the same as +353?
Yes. 00 is the international prefix used from a UK landline; + is the same prefix on a mobile. 00353 87… and +353 87… are the same Irish mobile.
What country is an 087 phone number?
Ireland. 087 is an Irish mobile prefix. From the UK it displays as +353 87. It is not a UK 07 mobile.
How much does it cost to call +353 from the UK?
On EE, the published standard rate to Ireland on 8 September 2026 was 25p a minute to mobiles and landlines. O2, Vodafone and Three publish their own rates. The call is not part of your UK inclusive minutes unless you have an international add-on that lists Ireland.
