As an overseas department of France (DROM), Guadeloupe is a unique fiscal territory. While it follows the French commercial code and uses the Euro, it maintains its own specific VAT rules and customs status outside the EU VAT area. In 2026, the primary challenge for businesses is the transition to the mandatory e-invoicing (Facturation Électronique) mandate, which aligns with the mainland French rollout. Understanding identifiers like SIREN, SIRET, and the SPI is critical for any entity operating in the “Butterfly Island.”

10 Essential Questions About TIN in Guadeloupe
Common Questions
1. What is a TIN in Guadeloupe?
Guadeloupe uses the French national system for tax identification. There is no single "TIN" label; instead, identification is split between individuals and businesses:
-
For Businesses: The SIREN (9 digits) is the legal identifier, and the TVA Intracommunautaire (FR + 11 digits) is the tax identifier.
-
For Individuals: The SPI (Simplification des Procédures d'Identification) is the unique 13-digit number used for personal income tax.
