An incoming call displaying a number starting with 0162 corresponds to a geographical code linked to Île-de-France. This prefix, assigned by ARCEP, is used by both local professionals and call centers that rent blocks of numbers via VoIP platforms. The challenge lies precisely there: distinguishing a legitimate call from a commercial solicitation even before answering.
Distinguishing a local professional from a call center on a 0162 number
The 0162 prefix resembles a typical landline number in the Île-de-France region. Craftsmen, medical offices, and local administrations use it daily. The problem is that call centers exploit this appearance to bypass the distrust that clearly commercial numbers evoke.

Consumer associations have reported since 2023-2024 a significant increase in reports of robocalls posing as public services or energy renovation assistance, specifically using geographical numbers starting with 01. To learn everything about the 0162 number and its misuses, the most reliable reflex remains to cross-check multiple sources of information before calling back.
Three quick checks can help sort a received 0162 call:

- Run the full number through an online reverse directory or a reputation app (Truecaller, Hiya). A legitimate professional typically appears with a name, address, and declared activity.
- Check recent reviews associated with the number on reporting forums. A number reported several dozen times in a few days is almost always a call center.
- Search for the number in quotes in a search engine. A medical office or a town hall will have its number displayed on an official site. A call center will have no coherent public trace.
Behavioral tests during the 0162 call to spot telemarketing
Technical tools are not always sufficient. When the number does not appear in any database, answering may sometimes be the only option. A few simple reflexes can then help qualify the call in less than thirty seconds.
A local professional introduces themselves with a specific name and context. A doctor calls back about an appointment, a craftsman mentions a requested quote, an administration cites a file. The call center, on the other hand, launches a generic pitch: renovation offer, free energy audit, insurance contract to renegotiate.
Second signal: the delay before a person speaks. Telemarketing campaigns use automated systems that dial multiple numbers simultaneously, then connect an operator when someone answers. This delay of a few seconds, followed by characteristic background noise (open space, keyboard clicks), consistently betrays a call center.
Final test: ask a question off-script. Requesting the exact name of the company and its SIRET number destabilizes an operator reading a script. A real professional will respond without hesitation. The absence of a clear answer regarding the SIRET is a reliable indicator of telemarketing.
Blocking unwanted 0162 calls on Android and iPhone
Once the number is identified as unwanted, technical blocking prevents any follow-up. The methods vary depending on the operating system, but the principle remains the same: add the number to a blacklist.
Native blocking on iPhone
In the call log, tap the “i” next to the concerned 0162 number, then select “Block this caller.” Calls, SMS, and FaceTime from this number will be redirected to voicemail without the phone ringing.
The “Silence Unknown Callers” feature (Settings > Phone > Silence Unknown Callers) sends any call from a number not in the contacts directly to voicemail. This option is radical: it also blocks legitimate calls from unregistered numbers.
Native blocking and apps on Android
Android offers similar blocking from the call log. On Samsung phones, the built-in anti-spam protection in the dialer automatically identifies numbers reported by the community.
Apps like Truecaller or Should I Answer use AI models to recognize patterns of automated campaigns. They specifically detect sequentially numbered series (for example, 01 62 XX XX 01, then 02, then 03), allowing the blocking of an entire campaign without manual intervention on each number.
Google also offers caller ID display and spam protection in its Phone app. When an unregistered number calls, the app queries its database to identify the caller or flag a suspicion of spam.
Legal reporting and Bloctel registration against telemarketing
Blocking a number on your phone resolves the individual problem. Reporting feeds collective databases and can trigger checks by the relevant authorities.
Registering with Bloctel, the national opposition register against telemarketing, prohibits professionals from contacting registered numbers. The service is free, and the protection lasts for three years, renewable. Companies that violate this prohibition face administrative fines.
Reporting to 33700 (via SMS) or on the DGCCRF’s Signal Conso platform is another lever. Each report of an identified abusive 0162 number enriches the data used to detect large-scale telemarketing campaigns.
Keeping call logs (screenshots with date, time, and number) serves as evidence in case of persistent harassment. If calls continue despite Bloctel registration and technical blocks, contacting the DGCCRF remains the most direct recourse to obtain intervention with the offending call center.
The combination of a reverse directory, a filtering app, and systematic reporting on official platforms covers almost all cases. The most useful link remains the behavioral test at the moment of answering: thirty seconds of attention is enough to avoid an unnecessary conversation and to add a verified number to your phone’s blacklist.
