Getting unsolicited phone calls in the middle of dinner or during a quiet moment at work has become a frustrating part of modern life. And while it’s tempting to slam the phone down the moment you hear a telemarketer’s script, that reaction may not be doing you any favours. There’s a smarter way to handle these calls — and it starts with outsmarting the system rather than fighting it.
Why hanging up just makes things worse
We’ve all done it: a number you don’t recognise flashes on your screen, and seconds after you answer, someone launches into a too-cheerful sales pitch. Your instinct? Hang up. But that tactic often backfires. Many call centres are programmed to re-dial numbers that disconnect too quickly, flagging them as potentially winnable.
Instead of feeding the cycle, try staying on just long enough to make it clear you’re not interested — politely but firmly. It reduces the chance of being called back and gives you a second to note the number for potential blocking.
The new rules are putting pressure on cold callers
In recent months, new regulations have tightened the leash on telemarketing practices. Callers must now display their numbers — no more mystery calls from hidden IDs. They’re also restricted to specific operating hours: 10am to 1pm or 2pm to 8pm, Monday to Friday. Weekends and public holidays? Strictly off-limits.
And the penalties are steep. Companies that ignore these rules risk fines up to €75,000 for individuals and €375,000 for organisations. If you get a sales call at 9pm on a Sunday, that’s not just annoying — it’s illegal.
How to spot a cold call before picking up
The trick is knowing what to look for. Thanks to new guidelines, telemarketers must use specific phone number prefixes, depending on their region. These identifiable area codes make it much easier to dodge unwanted calls.
Here’s a quick cheat sheet:
- Mainland France: 0162, 0163, 0270, 0271, 0377, 0378, 0424, 0425, 0568, 0569, 0948, 0949
- Guadeloupe, Saint-Martin, Saint-Barthélemy: 09475
- French Guiana: 09476
- Martinique: 09477
- Reunion and Mayotte: 09478, 09479
If a number with one of these prefixes pops up, you can safely let it ring out or send it straight to voicemail.
Tools that help block the calls for good
While identifying these numbers is helpful, you can take it a step further. One option is to sign up for Bloctel, a national do-not-call registry that legally prohibits marketers from contacting you. It's free, easy to sign up for online, and gives you a layer of legal protection — even if some callers try to bend the rules.
You can also use call filtering apps like Orange Téléphone, which taps into a community-driven database of known spam numbers. When someone flags a scam or sales number, that warning helps shield other users from falling for it in the first place.
Stay calm — and take control
It’s easy to get flustered when someone aggressive is on the other end of the line. But remember, many telemarketers are under immense pressure to meet quotas. That doesn’t excuse bad behaviour, but it explains why hanging up without a word can sometimes make things worse.
Instead, a calm “No thank you, please remove my number from your list” followed by blocking the number can do the job without adding fuel to the fire. With new tools, tighter regulations, and a few tricks up your sleeve, dealing with unwanted calls no longer has to be a daily headache.
