Area Code 45 – Nassau

Overview of the +682 45 Geographic Prefix

The +682 45 prefix is a geographic area code assigned to the Nassau region within the Cook Islands. As part of the country's national numbering plan, this prefix follows ITU-T E.164 recommendations, ensuring standardized international dialing. The Cook Islands, a self-governing island country in free association with New Zealand, utilize the country calling code +682, followed by a National Destination Code (NDC) that identifies a specific geographic area or service type.

Geographic Coverage and Administrative Jurisdiction

Nassau is one of the northern Cook Islands, located approximately 1,200 kilometers northwest of Rarotonga, the capital. Administratively, Nassau falls under the jurisdiction of the Cook Islands government, with telecommunications services regulated by the Ministry of Transport and Communications. The prefix 45 is allocated to landline services within Nassau, serving the island's small population, primarily engaged in fishing and copra production.

Dialing Formats and Caller Instructions

For local callers within the Cook Islands, dialing a Nassau number requires only the seven-digit subscriber number, which includes the area code. For example, to reach a local line, you would dial 45 1234 (assuming a four-digit subscriber number). However, for international callers, the full international format must be used: +682 45 1234. This format ensures proper routing through international gateways. When calling from a mobile phone, the plus sign (+) is typically used, but it can be replaced with the international access code (e.g., 00 in many countries) followed by 682 and the local number.

Overlay Considerations and Numbering Plan

Currently, there are no overlay codes in the Cook Islands numbering plan. The country's small population and limited number of landlines mean that each geographic area, including Nassau, has a unique prefix. This simplifies dialing and avoids the need for ten-digit dialing within the country. The numbering plan is managed to ensure sufficient capacity for future growth, but no immediate changes are anticipated.

Practical Tips for Callers

When calling Nassau from abroad, be mindful of time zone differences (UTC-10:00). Also, ensure you have the correct subscriber number, as the length may vary. For travelers, local SIM cards are available, but coverage in remote islands like Nassau may be limited to satellite or high-frequency radio. Always confirm the number with the recipient before dialing to avoid miscommunication.
