Ireland's €300 Million Scam Crisis: What You Need to Know

Ireland is facing an escalating wave of telecommunications fraud, with scam calls, texts, and increasingly sophisticated AI-powered scams targeting hundreds of thousands of people every year. Regulators are fighting back, but the threat is evolving faster than ever.

The Scale of the Problem

The numbers are stark. According to research commissioned by the Commission for Communications Regulation (ComReg), approximately 365,000 cases of fraud result from scam calls and texts in Ireland each year, roughly 1,000 cases every single day.

The estimated total harm to Irish society exceeds €300 million annually, split between €187 million attributed to scam calls and €115 million to scam texts. As an English-speaking country, Ireland is disproportionately targeted compared to many European counterparts, as international fraud networks can shift their operations seamlessly across the Anglosphere.

In 2022, approximately 91% of Irish mobile consumers and 74% of landline consumers received scam calls, while 84% received scam texts. More recently, a FraudSMART survey from March 2025 found that 78% of Irish adults are being targeted with scam messages, emails, calls, or online content at least once a month, with nearly half reporting an increase compared to the previous year.

What Are the Scams?

The three main types of telecommunications fraud are phishing, smishing, and vishing, and they all rely on the same underlying tactic: social engineering, which means manipulating people rather than hacking systems.

Phishing refers to fraudulent emails or messages designed to trick recipients into clicking malicious links or handing over personal information. Smishing is the SMS version, exploiting the immediacy of mobile notifications, while vishing involves live or automated phone calls impersonating banks, the Gardaí, Revenue, or utility companies.

Caller ID spoofing underpins many of these attacks. Fraudsters can manipulate the number displayed on your screen to make it appear to be a legitimate Irish or international number. In the run-up to Christmas 2025, Ireland saw a significant spike in calls appearing to come from UK +44 numbers, with automated voices typically claiming to represent recruitment or HR agencies in an attempt to extract personal information. Simply answering such a call can flag your number as active, leading to further targeting.

Another tactic, known as Wangiri or "one ring and drop," involves automated short calls designed to prompt a call-back to a premium-rate international number, generating revenue for scammers through interconnect charges.

The AI Voice Cloning Threat

The threat landscape has taken a more alarming turn with the rise of AI voice cloning. Modern AI tools can clone a specific individual's voice using as little as three seconds of sampled audio, sourced from social media videos, voicemail greetings, or online content.

Fraudsters use these cloned voices to impersonate family members in distress, calling victims and claiming to be in a medical emergency, legal trouble, or accident, demanding an urgent transfer of funds. The emotional impact of hearing a loved one's voice bypasses rational judgement, making even tech-savvy individuals vulnerable. Security experts strongly advise families to agree on a private "safe phrase" in person, known only to those closest to them, and to use it to verify the identity of anyone requesting urgent help by phone. The phrase should never be stored digitally or based on information that could be found online.

Fraud on the Rise

Garda crime statistics confirm the scale of the problem. Overall fraud offences rose by 73% in the first half of 2025 compared to the same period in 2024, with online shopping fraud up 166%, deception offences up 178%, and money laundering up 82%.

However, there are early signs that ComReg's network-level interventions are having some effect: instances of phishing, vishing, and smishing specifically reduced by 26% in the first half of 2025, with a reduction of as much as 52% recorded in the first quarter of the year compared to the same period in 2024.

What ComReg Is Doing

ComReg has implemented four mandatory voice interventions, which came into full effect in October 2024. These block calls from abroad that spoof Irish geographic numbers (such as 01 Dublin numbers), calls spoofing Irish mobile numbers (such as 087 or 085 prefixes), calls using unallocated or unassigned numbers, and calls using numbers listed on the Do Not Originate (DNO) registry, which covers inbound-only numbers used by banks and public bodies. Organisations can register their numbers for free at comreg.ie/dno.

Between February 2023 and October 2025, these four interventions blocked over 131 million scam calls, with more than 18 million blocked in September 2025 alone.

A fifth and more powerful measure, the Voice Firewall, is planned for deployment in the first half of 2026. Unlike the static blocking rules already in place, the Voice Firewall will use machine learning to analyse call signalling patterns and traffic volumes in real time, targeting sophisticated scam campaigns that adapt to avoid existing rules, including those using international numbers not covered by current measures. Some operators, including Three Ireland, have already deployed early implementations that display "Possible Scam" on calls assessed as medium risk, while outright blocking those assessed as high risk.

On the SMS side, ComReg launched an SMS Sender ID Registry in June 2025. Since 3 July 2025, text messages from unregistered Sender IDs have been modified to display "Likely Scam" on recipients' devices. Over 17,000 Sender IDs from more than 12,700 organisations have been registered. The full blocking phase, originally planned for October 2025, has been deferred while some technical issues with SMS routing are resolved by industry parties. The "Likely Scam" label remains active in the meantime.

ComReg estimates the combined net financial benefit of all interventions at approximately €1.2 billion by 2030, with roughly €50 in economic and social benefit generated for every €1 spent.

How to Protect Yourself

The golden rule, repeated consistently by ComReg, An Garda Síochána, and FraudSMART, is simple: hang up. Never provide personal information, bank details, PPS numbers, card details, or passwords to an unsolicited caller, regardless of how legitimate they appear.

If you receive a call claiming to be from your bank, the Gardaí, Revenue, or any service provider, do not engage with the call. Hang up and contact the organisation directly using a number you find yourself through official sources, such as the back of your bank card or the official government website.

Do not follow instructions from automated messages, do not call back unknown numbers, and do not download any software at a caller's request. If you receive a text with a link, do not click it even if the message appears to sit in the same thread as legitimate messages from your bank; Sender ID spoofing makes this possible.

To report a scam call or text, you can forward the number by text to 7726, which is the standard reporting service for Irish mobile operators. If you believe you have lost money to fraud, contact your bank immediately and report the matter to your local Garda station or via Garda.ie.

There is no need to feel embarrassed if you have been targeted or even deceived; these scams are sophisticated, persistent, and designed by professionals specifically to overcome scepticism.
