As an overseas department of France, Guadeloupe utilizes the French national postal system managed by La Poste. The infrastructure employs the standard French five-digit Code Postal, which integrates the island into the broader European logistics network. This system ensures that mail for the various islands of the archipelago, including Grande-Terre and Basse-Terre, is sorted efficiently through mainland French hubs.
The Code Postal in Guadeloupe consists of five digits. The first three digits are always \"971\", which is the INSEE department code for Guadeloupe, while the final two digits identify the specific commune or post office.
