📍 Geographic Location of Federal Dependencies
Overview of Area Code 237 (Venezuela)
Area code 237 is a geographic National Destination Code (NDC) assigned to the Federal Dependencies of Venezuela (Dependencias Federales de Venezuela). This administrative region comprises over 600 islands, islets, and cays in the Caribbean Sea, under the direct jurisdiction of the national government. The code serves the capital island of Los Roques, the most populated and developed of the dependencies, as well as other island groups such as La Orchila, Los Hermanos, and Isla de Aves. Note that the larger islands of Margarita and Coche are not part of this code; they fall under the state of Nueva Esparta with area code 295.
Geographic Coverage and Dialing Formats
The 237 code is used for both fixed-line and mobile services on the islands, though the population is small and tourism is the primary economic driver. For local calls within the same area code, subscribers typically dial the seven-digit local number directly. For calls from other regions of Venezuela, the national trunk prefix 0 must be dialed before the area code: 0-237-XXX-XXXX. For international callers, the format is +58 237 XXX XXXX (or +58-237-XXXXXXX when using the full seven-digit local number). When dialing from a mobile phone in Venezuela, the national trunk prefix is often omitted, so 237 XXX XXXX may work, but using 0 is always safe.
Caller Instructions and Practical Considerations
- Local callers (within 237): Dial the seven-digit subscriber number directly (e.g., 123-4567).
- Domestic long-distance callers (outside 237): Dial 0-237-XXX-XXXX (e.g., 0-237-123-4567).
- International callers: Dial your country's exit code, then 58, then 237, then the seven-digit number (e.g., from the US: 011-58-237-123-4567; from the UK: 00-58-237-123-4567).
- Overlay considerations: As of 2025, there is no overlay code for 237; the region uses only this NDC. However, due to the small population, number capacity is not a concern.
Because the Federal Dependencies are remote, telecommunication infrastructure may rely on satellite or microwave links, which can occasionally cause latency or service interruptions. For emergency services, visitors should rely on local hotel or tour operator contacts, as standard emergency numbers may not be reachable from all islands.
