Unknown calls in the Netherlands
Unsure about a Dutch number? Here you can browse concise reports from the community to judge unfamiliar calls and texts. Around Amsterdam, Rotterdam, The Hague (Den Haag), Utrecht and Eindhoven you will see a mix of legitimate callbacks (deliveries, banking, appointments) alongside robocalls or phishing waves. Classic geographic prefixes like 020 (Amsterdam), 010 (Rotterdam), 070 (Den Haag), 030 (Utrecht) and 040 (Eindhoven), as well as mobile ranges (06), no longer prove location or caller identity because of portability and VoIP — treat them as context only.
Verification basics: return calls via the official number listed on the company website/app, check in‑app messages, and never share one‑time codes over the phone. Use device/carrier blocking for repeat offenders and add a short, factual note here (caller type, purpose, date, cues) so others can benefit from your experience.

Dit betreft Mofa Afwerkingsbedrijf in Veenendaal, gwn.
Na die telefoontjes begon mijn scherm te haperen, en een enge stem fluisterde nummers voordat de telefoon afsloot. Ik liet het repareren voor €2.000, gelukkig was het niet ernstig, maar ik zag weer mijn reboot‑scherm. De technici zeiden dat het gehackt was. Nu heb ik een nieuwe telefoon van €1.500 gekocht en ben binnen één dag meer dan €3.500 kwijt, man.
Nog een nummer dat geen gerechtigheid biedt zodra je opneemt. Wees alert op dit soort nummers.

FAQ — Netherlands
How do I verify Dutch callers?
Call back using the official number from the company website/app, not the unknown number; check in‑app notices.
Do prefixes prove location?
No. Portability/VoIP mean 020/010/070/030/040 and 06 are not reliable evidence of origin.
What patterns are common?
Delivery and appointment confirmations, bank callbacks, 2FA codes; also parcel/account phishing and scripted sales calls.
What helps others in a report?
Be brief and practical: caller type, purpose, date, and hints that guided your decision.
