Area Code 3183 – St. Eustatius

Overview of +599 3183

The prefix +599 3183 is a geographic destination code assigned to the Caribbean island of St. Eustatius (commonly called Statia), which is a special municipality of the Netherlands and part of the Caribbean Netherlands. In the international E.164 numbering plan, the country calling code +599 is shared by Curaçao and the Caribbean Netherlands (Bonaire, St. Eustatius, and Saba). However, each island has its own national destination code (NDC) or prefix range. For St. Eustatius, the prefix 3183 is used to route calls to fixed-line subscribers on the island.

Geographic Coverage and Administration

St. Eustatius is located in the Leeward Islands of the Caribbean. Its capital is Oranjestad, and the island is known for its historical significance and small population. The prefix 3183 serves the entire island, including Oranjestad and the surrounding areas. As a geographic code, it is tied to the physical location of the subscriber's line, typically provided by the local fixed-line operator, which is part of the UTS (United Telecommunication Services) group, a subsidiary of Digicel. The island's telecom infrastructure is modern, supporting PSTN and VoIP services.

Dialing Formats

To call a fixed-line number on St. Eustatius from abroad, you must dial the international access prefix (e.g., 011 from the US, 00 from most countries), followed by the country code 599, the area code 3183, and the local subscriber number. The local subscriber number is typically 4 digits, making the total national significant number (NSN) length 8 digits (excluding the country code). For example, a complete international number might look like +599 3183 1234.

When calling from within St. Eustatius or from other islands in the Caribbean Netherlands (Bonaire and Saba), you can often use the national dialing format without the country code. In the national format, you would dial 3183 1234 (or sometimes just the 7-digit local number if the network allows). However, due to the small size of the island and shared numbering plan, it is always safe to use the full international format for clarity.

Overlay and Numbering Considerations

Currently, there is no overlay code for St. Eustatius; the prefix 3183 is unique to the island. However, as the Caribbean Netherlands transitions to a unified numbering plan, it is essential to always include the country code when dialing from outside the region. For callers within the Netherlands proper (Europe), dialing +599 3183 ... is required, as the Caribbean Netherlands is not part of the Dutch national numbering plan.

Caller Instructions

• International callers: Dial your country's exit code (e.g., 00 or 011), then 599, then 3183, then the 4-digit local number. Example: +599 3183 5678.
• Local callers (within St. Eustatius): Dial the 7-digit local number (3183 + 4 digits) or the full international format if your phone requires it.
• Callers from Curaçao or other Caribbean Netherlands islands: Dial 599 3183 ... (as if calling internationally) because each island has its own numbering.

Always verify the number length with your recipient, as some numbers may have been migrated to VoIP services, but the geographic prefix remains the same.
