Overview of Montserrat's +1 664 Geographic Code

Montserrat, a British Overseas Territory in the Caribbean, is integrated into the North American Numbering Plan (NANP). Its country calling code is +1, and the sole National Destination Code (NDC) is 664. This geographic prefix serves the entire island, including the current capital, Brades, and the former capital, Plymouth, which remains within the exclusion zone due to volcanic activity. The numbering area covers all administrative parishes, with no other area codes assigned to the territory.

Dialing Formats and Call Routing

For international callers, the format is +1 664 XXX XXXX, where the seven-digit subscriber number follows the NDC. Within the NANP (e.g., from the US or Canada), dial 1 664 XXX XXXX. Local calls on-island require only the seven-digit number, but due to the small population and integrated network, calls to other Caribbean NANP islands may require the full international format. The prefix is exclusively geographic, tied to the PSTN, mobile, and VoIP services operating under Montserrat's telecom license.

Coverage and Infrastructure

The 664 area code covers all inhabited areas, including Brades, Salem, St. Peter's, and the northern regions. The southern half of the island, including Plymouth, is largely uninhabited and lacks active infrastructure. The network is modern, with fiber-optic and 4G LTE coverage in populated zones. The sole fixed-line operator is Flow (Cable & Wireless), while mobile services are provided by Flow and Digicel. Number portability exists for mobile and fixed services, allowing users to retain numbers when switching providers.

Caller Instructions and Practical Notes

When calling from outside the NANP, always use the international prefix (e.g., 011 from the US, 00 from most countries) followed by 1 664 and the seven-digit number. For example, a call to a Brades business would be dialed as +1 664 491 2345. Local callers should be aware that while seven-digit dialing is standard, some VoIP services may require the full NANP format. Emergency services are reached via 911, and the island uses the same emergency infrastructure as other NANP members.

Given the island's volcanic history, some legacy numbers in the exclusion zone may be inactive. Always verify the number with the called party if you experience issues. The 664 code is not an overlay; it is the only code for Montserrat, simplifying dialing procedures.

❓ Frequently Asked Questions

What is the international dialing format for Montserrat?

To call Montserrat from abroad, dial your country's international prefix (e.g., 011 from the US, 00 from the UK), then 1 (the NANP country code), then 664 (the area code), followed by the 7-digit local number. Example: +1 664 491 2345.

Is 664 a mobile or landline prefix?

664 is a geographic area code assigned to Montserrat. It is used by both fixed-line and mobile services. The prefix itself does not distinguish between landlines and mobiles; you must check the number's context or use a reverse lookup.

Can I dial a Montserrat number without the 664 area code?

Within Montserrat, local calls can be made using only the 7-digit subscriber number. However, if you are calling from outside the island or from a VoIP service, you must include the full international format: +1 664 followed by the 7-digit number.

Why does Montserrat use the +1 country code?

Montserrat is part of the North American Numbering Plan (NANP), which includes countries and territories in the Caribbean and North America. The +1 country code is shared among all NANP members, and each territory or region is assigned its own area code, such as 664 for Montserrat.

Are there any special charges for calling 664 numbers?

Calls to 664 numbers are typically billed as international calls if you are outside the NANP. If you are within the NANP (e.g., from the US or Canada), they are treated as domestic long-distance calls. Rates vary by carrier, so check with your provider for specific charges.
