Another effective method to make your number private is to enroll in the National Do Not Call Registry. This registry is managed by the Federal Trade Poland Phone Number Commission (FTC) and allows individuals to add their phone numbers to a list that telemarketers are prohibited from contacting. By registering your phone number with the National Do Not Call Registry, you can reduce the number of telemarketing calls you receive.

Furthermore, consider utilizing a third-party call-blocking app or service. These services are specifically designed to filter out unwanted calls and prevent them from reaching your phone. Many of these apps use algorithms to identify telemarketer numbers and automatically block them. Some popular call-blocking apps include Truecaller, Nomorobo, and Hiya. By using one of these apps, you can effectively block telemarketer calls and protect your privacy.
