Check unknown Dutch numbers with recent community reports (Amsterdam, Rotterdam, The Hague, Utrecht, Eindhoven) and share your experience.
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.
Recived a voicemail from a nummer with a likeness to AI, sounding like a womens voice, claimin to be from Linda milieu advies, but the conection was interupted
I have no idear why they called me from this number but they hung up immediatly.
They say nothing and then hang up
Bedrijf: Spatial & Fine Art Inc. (Amsterdam Zuidoost), oké
Vestiging Rossum, Gelderland: Organisaties & Mensen B.V.
Greenchoice keep calling, so i block'd it and now i dont have to deal with it no more
Associated with a primary school in Berkel en Rodenrijs, specifically the main building
Advies van VSR, Beverwijk
Waterbeheersing Groot Wildenberg (Diepenveen)
Net een belletje van dat nummer gekregen; even stilte, daarna hing ze op, man.
Ze beweren te bellen namens KPN, wat opdringerig is. Ondanks dat ik nee zeg blijven ze bellen. KPN, pak dit aan!
They call frequently with diferent numbers each time
Ik ben ook ooit klant geweest, maar het is niet verstandig om iets aan de deur, op straat of via de telefoon te kopen. Ik heb dit nummer als spam gemeld, maar ze gebruiken waarschijnlijk gewoon weer een ander nummer.
After blocking another GreenChoice number, they're now using this one; previously a customer but no longer interested
NEVER ANSWER AND BLOCK THIS NUMBER IMMEDIATELY!!! THESE ARE SCAMMERS TRYING TO DECEIVE YOU!!!
Ontwerpbureau Green Design (Zutphen) – nice!
The call was blocked immediately
Blocked due to disturbance
I also blocked an other number from Greenchoice because they keept calling non stop, even after i told them to stop, that evening i recived an other call, now both numbers are blocked, atleast i know wich energi compagny to avoid
Greenchoice is spamming, and they won't stop
Call back using the official number from the company website/app, not the unknown number; check in‑app notices.
No. Portability/VoIP mean 020/010/070/030/040 and 06 are not reliable evidence of origin.
Delivery and appointment confirmations, bank callbacks, 2FA codes; also parcel/account phishing and scripted sales calls.
Be brief and practical: caller type, purpose, date, and hints that guided your decision.
