Luxemburg

Q: Why does the same street name appear multiple times with different postal codes?

Luxembourg utilizes a highly granular postal system. A single long street (e.g., "ROUTE DE THIONVILLE") is often segmented into multiple postal codes based on house number ranges. You cannot simply map a street name to a single code; you must validate the specific house number against the rules in the rue_no column to assign the correct 4-digit code.

Q: How do I interpret the logic in the 'rue_no' column?

This column defines the precise address range and parity for the postal code. Common patterns include:
· Even/Odd indicators: e.g., "Even from no.66 to no.174" means the code applies only to even numbers (66, 68... 174) in that range.
· Range limits: e.g., "from no.1 to no.100" means all numbers in that range use the code.
Your system must parse this text to determine if a user's house number falls within the specified criteria.

Q: What is the difference between 'commune' and 'ville'?

These represent different levels of the administrative hierarchy:
· Commune: The local government unit (Municipality), which may consist of several towns.
· Ville: The specific town, village, or locality name within that commune (e.g., Commune "HESPERANGE" contains the Ville "ALZINGEN").
For postal addressing, the ville is typically used as the city name line.

Q: In what language is the data provided?

The dataset is provided in French, which is the official administrative language for postal addresses in Luxembourg (e.g., "RUE DE LA GARE", "LUXEMBOURG-CAMPAGNE").

Q: What is the format of the postal code?

Luxembourg uses a 4-digit numeric postal code (e.g., 5863, 4940). This is found in the code_postal column.
