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.
This morning, I received a message stating that a bailiff will arrive on January 24, 2025, if I don't pay up
The caller hung up quickly, leaving me puzzled
Do not answer this call
This number belongs to tandpraktijk van Rijswijck, Druten
Apparently, my phone number is being used for spoofing purposes, which means the recipient sees my number on their phone, but the call isn't actually coming from me.
Upon answering the call, it was immediately hung up after 3 seconds.
Upon answering, a message says 'you will be connected with your correspondent', but it's not worth waiting for.
Preventie Enzo - Kramer is a scam in Oudega, gemeente Súdwest Fryslân Friesland
I have been harassed by this number day and night, and I'm not going to tolerate it; I decide which numbers I answer.
After saying hello twice, the caller hung up, leaving only silence.
Likely scammers
Yarden calls from 088 927 3927 for a customer satisfaction survey, but they call persistently, even daily
Despite numerous calls, including late at night and early in the morning, the caller remains silent after answering, which is suspicious and has led me to add it to my phone's blacklist, hopefully putting an end to the calls; the 'do not call' registry has been ineffective
Yarden is callding every body who has a insurance policie under €4000 to sel them an other policie, even if you allready have one, they dont seem to no that, and when you say you wil cal them back, they dont, thats not how you treat customers
Someone from Yarden contacted me
identified as KBC Optimising People located in Huizen
Komt uit F.J. Heidinga, een lokaliteits adres
This appears to be a number for Cafetaria 't Pandje in Numansdorp
Associated with W. Waaijers Service & Onderhoud in Helmond
Apparently related to 't Tapperijke B.V. in Hoeven
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.
