After moving to a new address, we must declare it to official authorities, organizations, utility services, courts, etc. and also inform friends and colleagues.
The problem is solved by getting a Digital Postal Address afaiss. We create an account, insert our address/es, and declare the afaiss as our postal address. After moving to a new address, we update our afaiss account and all address databases are simultaneously updated.
The digital postal address afaiss remains the same for a lifetime and it is a cross-border communication tool. Personal data are GDPR protected.
