Economy and business landscape of Yonne
The economy of the Yonne rests first on agriculture, with large-scale cereal farming and milling especially present in the Sénonais area, and above all on viticulture, around the Chablis vineyard and the appellations of Auxerre, Irancy and Vézelay that give the department its reputation. Its industrial fabric, organised around Auxerre, Avallon and Sens, combines food processing, mechanical engineering and materials. Benefiting from its proximity to Paris and the A6, A5 and A19 motorways, the department has also developed substantial logistics and distribution activities, while tourism draws on a recognised heritage (the UNESCO-listed Vézelay basilica, the Guédelon medieval building site and the Morvan regional nature park).

A SIRET number consists of 14 digits: the first 9 form the SIREN number (unique identifier of the company), and the last 5 constitute the NIC (Internal Classification Number), which identifies the establishment within the company. The last digit of the SIRET is a control key calculated using the Luhn algorithm.
Yes, the generated SIRET numbers are algorithmically valid (correct Luhn key) and can be used to test forms, APIs or databases that validate the SIRET format. However, they do not correspond to any real company in the INSEE SIRENE register.
The SIREN (9 digits) identifies a company as a legal entity. The SIRET (14 digits) identifies a particular establishment of that company — a physical address. The same company can have multiple SIRETs (head office + branches), but only one SIREN.
