📋 The essentials at a glance: Personally, I consider calls starting with 09 48 to be treated with absolute suspicion, as this range has become the favorite playground of automated prospecting centers. More than 80% of these calls involve aggressive telemarketing, often bordering on illegality. I suggest you never respond with “Yes” during the first few seconds to avoid any fraudulent recording of your consent.
Repeated calls, suspect numbers, and intrusive solicitations disrupt the peace of your daily life, generating stress and frustration with every ring. Faced with the multiplication of phone spam from 09 48 numbers, it becomes urgent to regain control over your communications. The concern related to the security of your data and the threat of scams sets in, making every unknown call a source of mistrust. To regain serenity and protection, there are concrete and accessible solutions: understand the origin of these calls, identify the risks, then apply proven methods of filtering and blocking. Proceed methodically, secure your exchanges, and reduce the impact of spam through simple and effective reflexes.
🗣️ My experience: As recently as February 2026, I was harassed by a 09 48 number for an entire week, receiving four calls per day. When I finally answered, a robot offered me insulation for 1 euro, an offer that has been obsolete for years. The lesson learned is clear: if the caller does not leave a message after two attempts, the call has no real importance.
What uses lie behind numbers starting with 09 48?
Numbers starting with 09 48 come from an internet telephony technique, VoIP, offering companies easy access to telephony without geographical constraints. This flexibility facilitates massive telemarketing, as companies can multiply their lines at lower cost and reach a wide audience without regional restrictions. Calls from these numbers often involve commercial spam, prospecting, or attempts at manipulation to obtain personal information.
The reliability of the call then depends on the context and the identification of the caller. Call centers frequently use these numbers to create an impression of proximity, but this technique also allows for fraud and identity theft by malicious actors. Vigilance remains essential to distinguish a legitimate call from a scam.

Main characteristics of 09 48 numbers
- VoIP origin: Lines created via the internet without precise location
- Low cost: Economical solution for companies
- Massive use: Preferred tool for telemarketing

Why are these numbers associated with phone spam?
The use of numbers starting with 09 48 has intensified with the rise of phone spam. Telemarketing platforms use specialized software to manage a high volume of calls and bypass traditional blocking systems. Callers take advantage of the limited filtering on these number ranges to multiply contact attempts, often for commercial or fraudulent purposes.
Consumers thus face constant pressure despite the prevention and protection measures implemented. The difficulty in identifying the real origin of the call fuels confusion, making reporting and control more complex for authorities.

|---|---|---|---|
| 09 48 | VoIP (Internet) | Commercial solicitation | Very high |
| 09 70 | Internet Box | Customer services / Individuals | Medium |
| 01 to 05 | Landline | Administrations / Relatives | Low |
| 08 99 | Premium rate | Ping Call scam | Maximum |
Risks and usage contexts of 09 48 numbers
- Mass spam: Multiplication of unwanted solicitations
- Impersonation: False identity to deceive the recipient
- Spoofing: Hijacking numbers to mask the sender
- Automated calls: Large-scale robots or scripts
- Potential scam: Attempts to steal data or money
🌍 Did you know?
Since January 1, 2023, Arcep has reserved certain number ranges, including 09 48 and 09 49, exclusively for commercial solicitation. If a number of this type calls you, you now know with 100% certainty that it is a solicitation and not a private call.
How does regulation govern the use of these numbers?
French regulation has imposed since January 2023 a strict restriction on the use of mobile numbers for solicitation. Companies must now favor the 09 ranges, but many resort to spoofing software or impersonation to continue contacting individuals via unauthorized numbers. The law also requires verifying the presence of contacts on the Bloctel list before any commercial call.
Despite these controls, many actors circumvent the legislation by regularly changing their number or operating from abroad. Sanctions exist, but the effectiveness of control depends on reporting by users and the ability of organizations to enforce the law.
What solutions exist to filter and block unwanted calls?
👍 Strengths
- Immediate identification of telemarketing
- No surcharge on reception
- Easy to filter by applications
👎 Weaknesses
- Frequent harassment
- Often robots (automata)
- Masks the real identity of the caller
To limit the impact of phone spam, several blocking and filtering tools are available. Registration on the Bloctel list allows you to express your opposition to telemarketing and offers a first barrier against abusive solicitations. Applications and software such as CPR Callblocker or Orange Phone enhance protection by automatically identifying and blocking suspicious calls.
Complement these technical solutions with daily vigilance. Only answer numbers you know or that are on your whitelist, and systematically report any fraud or scam. The combination of these tools optimizes prevention and reduces exposure to spam.
💡 Tip
If you receive too many calls, activate the ‘Silence unknown numbers’ option in your smartphone settings. Only your contacts will be able to ring you; others will be directly redirected to your voicemail without disturbing you.
Tools and advice to protect yourself effectively
- Bloctel registration: Limitation of commercial telemarketing
- Blocking applications: Automatic call filtering
- Whitelist: Authorization of only reliable numbers
- Reporting: Notification of fraudulent calls to authorities
- Regular verification: Updating authorized contacts
⚠️ Misconception
Many people think that insulting the telemarketer will get them removed from the list. It’s the opposite: by staying on the line, you confirm that your line is active and ‘reactive’, which increases its value in databases resold among spammers.
How to report a spam or phone scam?
Reporting a phone spam helps strengthen collective protection and enforce regulations. Use the J’alerte l’Arcep website or send an SMS to 33700 to submit information about the suspicious call. The more reports there are, the more the authorities can take targeted actions against malicious operators.
Additionally, consider removing your numbers from commercial files via the do-not-call lists managed by the Cnil or consumer associations. This prevention reduces the circulation of your contact details and limits exposure to manipulations and scams.
In 2022, Arcep recorded a 30% increase in complaints related to phone spam on numbers starting with 09 48, illustrating the scale of the phenomenon.

What reflexes should you adopt when receiving a suspicious call from a 09 48 number?
Before answering a call from a 09 48 number, verify the identity of the caller. Only call back if the message or request seems legitimate. Be wary of urgent solicitations or questions about sensitive data, as spoofing and identity theft are common with this type of number. Simply refusing to answer or requesting written contact often thwarts an attempted fraud.
If in doubt, use an app or software for filtering to check the reputation of the number. These tools compare incoming numbers against databases listing spam and alert the user in real time. This active protection reduces the risk of scams and secures phone communications.
Always report any attempt at manipulation or scam to official platforms. This reporting helps strengthen prevention and improve control over operators regarding abusive practices. The more the community shares feedback, the more effective the blocking becomes.
How to distinguish a commercial call from a scam attempt
A commercial call complies with legislation and clearly identifies itself, whereas a scam is characterized by unusual requests or pressure to obtain confidential information. The absence of identification or difficulty obtaining verifiable contact details should alert you to a possible fraud attempt.

Specialized applications automatically detect numbers associated with spam or abusive solicitation thanks to regularly updated lists. Using them allows for instant blocking of unwanted calls and provides real protection against fraudulent calls.
- Systematic verification of the number before answering
