What is the country code for French Guiana?
French Guiana is France — constitutionally, legally and administratively. It sends representatives to the French National Assembly and the Senate, uses the Euro, and its residents carry French (and therefore EU) passports. Yet it dials on +594, not France's +33. This is because the ITU allocates country codes by territory, not by sovereignty, and French Guiana is geographically separated from metropolitan France by roughly 7,000 kilometres of Atlantic Ocean.
The practical result is striking: the Guiana Space Centre in Kourou — from which Arianespace, the European Space Agency and now SpaceX launch rockets — is on European Union soil, but telephonically it sits in the +594 zone. A call from the launch control room in Kourou to ESA headquarters in Paris is an international call between two different country codes. A call from Kourou to Cayenne, 60 kilometres down the road, is a local call within +594.
French Guiana is, alongside Guadeloupe (+590) and Martinique (+596), one of three French territories in the Americas with its own country code — a trio that reflects the ITU's geographic logic colliding with France's constitutional indivisibility.
Code +594 was assigned to French Guiana by the ITU under the E.164 plan. The “+” means “dial your local international exit code”; on a mobile, press and hold 0 to type it.
All four mean the same thing — they connect your call to French Guiana.
How to call French Guiana from anywhere
The pattern: your exit code + 594 + the 9-digit subscriber number (drop the leading 0 used locally). Local numbers are written as 0694 XX XX XX (mobile) or 0594 XX XX XX (landline) — dropping the leading 0 and adding +594 gets you the international format. Important: calling from metropolitan France to French Guiana is NOT a domestic call despite both being France — you must dial 00 594 (or +594), not just the local 0594/0694 number.
Full example: +594 694 12 34 56 — locally written as 0694 12 34 56; drop the leading 0 and add +594 when calling from abroad.
French Guiana phone number format explained
French Guiana follows the French 10-digit numbering system. Locally, numbers are dialed as 0 + 9 digits. Internationally, drop the leading 0 and use +594.
Landline numbers start with 0594 locally (594 594 internationally). Mobile numbers start with 0694 locally (594 694 internationally). The 9-digit subscriber number after +594 follows this pattern: the first three digits identify the service type and operator, and the remaining six are the subscriber number.
Landline
+594 594 XX XX XX (landline, locally 0594 XX XX XX)
Mobile
+594 694 2X XX XX (Orange Caraïbe) · +594 694 3X XX XX (SFR Caraïbe) · +594 694 4X XX XX (Digicel)

French Guiana mobile network prefixes
The prefix after +594 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.
Orange Caraïbe
Subsidiary of Orange France; largest mobile operator, providing 2G/3G/4G LTE coverage across coastal areas and major towns.
SFR Caraïbe
Société Française du Radiotéléphone, Caribbean division; offers mobile and fixed services.
Digicel Antilles-Guyane
Primary competitor to Orange; 2G/3G/4G LTE, known for competitive prepaid plans.
French Guiana time zone
French Guiana operates on French Guiana Time (GFT), UTC−3, year-round with no daylight saving. This puts it in the same time zone as Buenos Aires, Montevideo, São Paulo and the Falkland Islands.
For business calls, aim for 8 AM – 12 PM GFT. Government offices typically follow French hours: 8:00 AM – 12:00 PM, then 2:00 PM – 5:00 PM, with a substantial lunch break. The Guiana Space Centre in Kourou operates on its own schedule during launch campaigns.
Emergency numbers in French Guiana
Free to call from any French Guiana phone, landline or mobile.
Common mistakes when calling French Guiana
Almost every failed international call is a formatting issue, not a network issue.
Using France's +33 code
French Guiana is part of France, but it uses +594, not +33. Dialing +33 followed by a 0594 or 0694 number will fail — it connects to metropolitan France's numbering plan.
Keeping the leading 0 when dialing internationally
The 0 in 0694 or 0594 is a trunk prefix for local use. From abroad, drop it: dial +594 694 or +594 594.
Confusing +594 with +597 (Suriname)
Suriname, French Guiana's western neighbour, uses +597. The codes differ by a single digit.
Assuming metropolitan French rates apply
Calls from France to French Guiana are technically international. Most French mobile plans include DOM-TOM (overseas departments) in their bundles, but check — some budget plans exclude overseas territories.
Not accounting for the time difference with France
French Guiana is 4–5 hours behind Paris. A 9 AM call from Paris reaches Cayenne at 4 or 5 AM.
Tips to reduce the cost of calling French Guiana
Check whether your French carrier bundles DOM-TOM calling
Most major French carriers (Orange, SFR, Free, Bouygues) include DOM-TOM territories in their unlimited calling bundles — verify your specific plan before assuming standard rates apply.
Route calls over VoIP from outside France
WhatsApp, Skype, and Zoom work well in coastal French Guiana where 4G coverage is solid, bypassing per-minute international charges.

Why businesses get a French Guiana virtual number
French Guiana's economy is driven by the Guiana Space Centre (CSG) in Kourou — the European Space Agency's primary launch facility and France's window to space — along with the French military garrison, gold mining, fishing, forestry and an expanding services sector fuelled by French government spending. The space centre alone attracts aerospace contractors, satellite operators, launch-service providers and engineering firms from across Europe. Beyond aerospace, French Guiana serves as France's (and the EU's) foothold in South America, making it a gateway for trade and logistics between Europe and the continent.
