Calling to French Guiana
- Do not dial a leading ‘0’ in the international call sequence unless calling from France or a French Overseas Department or Territory (except for those in the Pacific) – it is used in French Guiana for domestic calls and for calling within the French numbering plan.
- ‘594’ is both the country code for French Guiana as well as the first three numbers for landline phone numbers within French Guiana. Many international callers will dial ‘594’ twice in the phone call – once for the country code, and once for the local phone number.
- French Guiana’s phone numbers may be listed with country code ‘+33’ (France) or with country code +594. Either +33 or +594 can be dialed for calling French Guiana.

French Guiana’s phone numbers explained
Number details
French Guiana’s phone numbers are nine digits (ten including a leading ‘0’ that is not dialed when calling from outside the region). The leading ‘0’ for local calls within French Guiana or calls from France or French Overseas Departments and Territories (except for those in the Pacific).
The first three digits designate whether the phone number is a landline (‘594’) or mobile (‘694’) – these numbers exist to make the French Guiana phone system compatible with the French system. Note that the country code for French Guiana is also ‘594’, resulting in ‘594’ being dialed twice in the phone number.
Mobile numbers begin ‘694’.

International example – calling from outside French Guiana
To call from outside French Guiana, dial the exit code of the country the call is dialed from, followed by French Guiana’s country code of ‘594’, followed by the local phone number.
Do not dial any leading ‘0’ listed in the French Guiana phone number.
Many phone numbers dialed through the international call sequence will dial ‘594’ twice in a row. This is normal, as ‘594’ is both the country code for French Guiana as well as the first three numbers of landline phone numbers in French Guiana.
