Q: In what language are the data and documentation provided?

The dataset maintains the official French nomenclature (e.g., column headers like nom_de_la_commune, libelle_d_acheminement) to strictly adhere to La Poste standards. However, a comprehensive user guide in English is included with your purchase, providing detailed translations and technical definitions for every field.

Q: What is the difference between `nom_de_la_commune` and `libelle_d_acheminement`?

This is a critical distinction for logistics:
· nom_de_la_commune: The official administrative name of the municipality.
· libelle_d_acheminement: The standardized Postal Routing Name (always in uppercase). For shipping labels and mail sorting, you must use the libelle_d_acheminement, as this is the format recognized by the French postal service (La Poste) for automated sorting.

Q: What is the purpose of the `ligne_5` column?

In French addressing standards, "Ligne 5" (Line 5) is reserved for specifying a distinct locality or a former commune name. This is essential because many French communes have merged. For example, the new commune Arboys en Bugey includes the former communes of Arbignieu and St Bois. The ligne_5 column captures these specific locality names to ensure precise delivery within merged territories.

Q: Why do I see the same commune name listed multiple times with the same postal code?

This reflects the granular nature of the dataset. When a commune (e.g., "BAGE DOMMARTIN") is formed by merging smaller towns, we provide a separate record for each former entity (e.g., "BAGE LA VILLE", "DOMMARTIN") in the ligne_5 column. This allows you to validate addresses using both modern and legacy town names.

Q: What is the format of the postal code?

France uses a 5-digit numeric postal code (e.g., 01300, 75001). This is found in the code_postal column.

Q: What file formats are included in the delivery?

The package includes CSV, Excel (.xlsx), and TXT formats. All files are encoded in UTF-8 to preserve French characters (accents like é, è, ç) correctly.

Q: Is this a one-time purchase or a subscription?

This is a one-time purchase. The license grants perpetual use for internal business purposes with no recurring fees.

Q: What is the refund policy?

Due to the digital nature of the product, all sales are final and non-refundable. We recommend downloading the Free Sample to inspect the structure of the `ligne_5` and routing columns to ensure they meet your logistical requirements before purchasing.
