Swindlers' Telephone Line-up: The listed phone numbers are at present in the possession of fraudsters
In the bustling cities of Düsseldorf, Hamburg, and across the Netherlands, residents have been plagued by an unwelcome intrusion - spam calls. According to recent reports, the number of these nuisance calls has reached an all-time high, as confirmed by caller ID and anti-spam app Clever Dialer.
These unwanted calls, often disguised as health insurance companies, consumer protection agencies, or even well-known companies like Telekom or Ergo Insurance, are a growing concern for many. One particular landline number from Düsseldorf, claiming to be from the consumer protection agency, has been especially prominent, offering to delete personal data for free.
However, the elusive nature of these scammers means that they are constantly changing their phone numbers to evade detection. This makes it challenging to compile a comprehensive list of common spam call numbers, a fact that was evident in the July 2025 data from Clever Dialer and Tellows databases.
While the situation in the United States has been more thoroughly documented, with loan-related scams topping the list of most frequent spam calls, using toll-free or U.S.-based numbers, according to YouMail's robocall index[1], the specific regional spam numbers for Germany (Düsseldorf, Hamburg) or the Netherlands were not listed in the sources provided.
It's important to note that unsolicited calls are illegal in Germany, but the ever-changing tactics of these scammers make it a continuous battle for authorities and citizens alike. The goal of these spam calls remains the same: to steal bank data or trick people into signing contracts under false pretenses.
As the battle against spam calls continues, it's advisable for residents to remain vigilant and cautious. Checking local German or Dutch consumer protection sites, telecom authorities, or databases like Clever Dialer and Tellows directly might provide updated regional-specific data.

Technology has become a critical tool in the fight against spam calls. The use of caller ID and anti-spam apps like Clever Dialer helps identify the unwanted calls that have become a nuisance for residents in cities like Düsseldorf and Hamburg. Despite the changing tactics of scammers and their use of multiple phone numbers, staying informed through local consumer protection sites, telecom authorities, or databases can aid in recognizing and avoiding potential threats.
