Mobile vs landline in French Guiana

French Guiana uses the French numbering plan under country code +594, which means the same logic applies here as in metropolitan France — but with its own local digit pattern. Mobile numbers begin with 694 (after the country code: +594 694 xx xx xx), while landlines in Cayenne and around the territory start with 594 followed by a 5 (so the full sequence becomes +594 594 xx xx xx). That doubling of 594 in the landline format surprises first-time callers; it's correct. Callers reaching businesses in Kourou — the site of the European space center — will encounter standard French-format office lines that follow the same landline pattern. The mobile penetration rate is high, and most personal contacts will give you a 694 number as their primary. Premium-rate 08x numbers from metropolitan France don't normally appear in French Guiana, simplifying the picture.

Saving money on calls to French Guiana

French Guiana operates on GFT (UTC-3), three hours behind mainland France, with no daylight saving adjustment. That fixed offset makes scheduling reliable year-round: when it's noon in Paris it's 9 AM in Cayenne, a clean overlap for business calls. European callers benefit from reaching Cayenne in the morning before the local lunch break, which runs long by French tradition. Calls to French Guiana landlines generally cost less per minute than calls to 694 mobiles, particularly from outside Europe, so favor the fixed number for longer conversations with offices or institutions. The Carnival season — which dominates the social calendar from January through mid-Lent and is more intense here than in metropolitan France — significantly affects business rhythm, with partial closures and reduced availability on the biggest Carnival days.
