No, all numbers generated are simulated. They use the correct country prefix and the local area codes assigned to Hauts-de-France, but the subscriber numbers are randomly generated for software validation purposes. They cannot make or receive calls, nor can they receive SMS verification codes.

Our database is regularly synced with official postal updates and open-source registry databases. While we strive to maintain high accuracy for development and testing purposes, you should always check the official national postal service for critical mailing validation.
