From “Wangiri” calls to fake jobs: the list of foreign prefixes used to empty accounts and steal data. How to recognize them and defend yourself
They almost always arrive at the wrong time: a single ring, an unknown area code, the instinct to call back “to understand”. That’s exactly where the trap opens. In 2025 the map of telephone scams has changed its skin, becoming more aggressive, more automated and – above all – international. The fraud ecosystem relies on foreign prefixes that bypass the average user’s defenses and turn a smartphone into a potential gateway to a bank account.
The most used prefixes? +27 (South Africa), +30 (Romania), +31 (Netherlands), +33 (France), +34 (Spain), +44 (United Kingdom), +49 (Germany), +60 (Malaysia), +62 (Indonesia), +84 (Vietnam), +91 (India), +92 (Pakistan), +218 (Libya), +223 (Mali), +254 (Kenya), +351 (Portugal), +353 (Ireland), +370 (Lithuania), +855 (Cambodia). A geography of risk that tells only one thing: the telephone has become the new battlefield, and not answering can be an act of self-defense.
Foreign prefixes to keep an eye on
These international prefixes have been reported as recurring in the main telephone scams (called “Wangiri”, fake jobs, false prizes, urgent payment requests):
- +27 – South Africa
- +30 – Romania
- +31 – Netherlands
- +33 – France
- +34 – Spain
- +44 – United Kingdom
- +49 – Germany

Attention: It doesn’t mean that all calls from these countries are scams, but if you don’t expect contact from abroad it’s prudent not to answer or call back.
The five scams that use foreign prefixes to empty accounts and steal data
Behind the phantom rings and sudden messages there is never improvisation. Only proven schemes, designed to transform curiosity into concrete economic damage.
Missed call “Wangiri”
A single vibration, the foreign number flashing, the temptation to call back. That’s where the mechanism kicks in: you end up with paid services that drain your credit and increase your bill. The speed of the operation is its strength: just a few seconds.
Fake job offers
High pay, flexible hours, perfect promises for uncertain times. The goal is always the same: to obtain copies of documents, personal data or a “small advance” destined to disappear forever.
Romance scams
Psychology replaces technology. Long messages, confidences, months of patiently constructed conversations. Then comes the urgent request: money for a trip, an illness, an accident. The result never changes.
Non-existent prizes and phantom competitions
The notification is tempting, the prize astonishing, the commission to be paid “just to finalize”. In reality, money and sensitive data are given away, handing them over to those who live off stolen identities.
Urgent payment requests
The bank, the post office, the courier: fraud chooses the most credible masks. We’re talking about overdue invoices, parcels stuck at customs, services to be released. Psychological pressure is the main weapon.
The common factor: speed, urgency, manipulation
Whether we’re talking about love, work or prizes, the ingredients are always the same: a foreign prefix, an immediate request, a link to click or a number to call back. The golden rule is almost banal, but it works: if they ask you to act quickly, stop. It’s the only form of time they can’t control.
How to really defend yourself: precautions that work
The first line of defense is the simplest: don’t respond. If the number is not expected and comes from a foreign area code, ignoring it is often the safest choice. Enabling your smartphone’s spam filter can eliminate most suspicious calls. Never call back numbers that have left a ring. If the contact comes via WhatsApp or other apps, block and report the sender. Don’t click links, don’t download attachments, don’t send documents. These are minimal behaviors, but enough to shatter the scammers’ strategy.
Why scams are increasing: the new economy of foreign numbers
Foreign area code fraud is the updated version of a global business that exploits digital remote controls, international SIMs, artificial intelligence and stolen databases. Every ring is an attempt to monetize human error. Every response can turn into a vulnerability.
