The Communications Regulatory Commission is developing a new system that provides for each property to have a number (similar to the Personal Identification Number of citizens). The goal is for every home, house, even a farm in the middle of a field, to have a code - a unique combination of numbers and letters with GPS coordinates. This will help with the quick delivery of letters and parcels to the address in question.
In case the property is sold, the code is retained and will be used by the next owner. The system will be improved, and it will be possible to obtain one new code when merging two neighboring properties into one, and to create two new codes when dividing two neighboring properties.
