The +1758 code is for Saint Lucia, a volcanic island in the Eastern Caribbean between Martinique and Saint Vincent. The "country code" is technically +1 (shared with the US, Canada, and other Caribbean nations under the North American Numbering Plan), and 758 is Saint Lucia's area code within that system.
This matters for billing. Even though you dial Saint Lucia the same way you'd dial any US area code — 1-758-XXX-XXXX — your carrier treats it as an international call. The rates are international rates. Many people learn this the hard way when the phone bill arrives.
Quick answer: From the US or Canada, dial 1-758 + the 7-digit local number. From other countries, dial your exit code + 1-758 + the 7-digit number. No trunk prefix. Landlines start with 450-458, mobiles with 712-719, 520, or 584.
How to call Saint Lucia: quick reference
Since Saint Lucia is part of the NANP, dialing from North America is the same format as a long-distance domestic call. From outside North America, you need your country's exit code first.

Understanding Saint Lucia phone numbers
Saint Lucia phone numbers follow the standard NANP format: a 3-digit area code (always 758) followed by a 7-digit local number. The full number is 10 digits: 758-XXX-XXXX.
Landline numbers
Landlines use exchange codes in the 450-458 range. A typical landline number looks like +1 758-450-XXXX or +1 758-452-XXXX. Most landline connections are in Castries (the capital) and Gros Islet in the north.
Mobile numbers
Mobile numbers use exchange codes 712-719 (Flow), 520 (Digicel), and 584 (Digicel). A typical mobile number looks like +1 758-712-XXXX or +1 758-520-XXXX. Mobile penetration is high — most Saint Lucians have at least one mobile phone, and many carry two (one per carrier) to take advantage of on-network calling rates.
Number format summary
| Type | Format | Example |
|---|---|---|
| Landline | +1 758-45X-XXXX | +1 758-452-1234 |
| Mobile (Flow) | +1 758-71X-XXXX | +1 758-714-5678 |
| Mobile (Digicel) | +1 758-520-XXXX | +1 758-520-9012 |
Mobile carriers in Saint Lucia
Saint Lucia has two mobile operators, which is typical for Eastern Caribbean islands. Competition between them keeps prices reasonable, though international roaming costs can still be steep.
Flow (Liberty Latin America)
Flow is the older carrier, formerly known as LIME and before that Cable & Wireless. It provides mobile, landline, broadband, and cable TV services. Flow is the only landline provider on the island. Mobile numbers on Flow use the 712-719 exchange range. Coverage is solid across the island, including the mountainous interior around the Pitons.
Digicel
Digicel entered the Saint Lucia market in 2003 and quickly grabbed market share with aggressive pricing and heavy sponsorship of local events and cricket. Digicel mobile numbers use the 520 and 584 exchanges. Their 4G LTE network covers the main population centers along the west coast and Castries.
Don't confuse +1758 with nearby codes
Several Caribbean islands share the +1 country code and have area codes close to 758. Misdialing by one or two digits lands you on a different island entirely.
| Code | Country | Why it's confused |
|---|---|---|
| +1 784 | Saint Vincent and the Grenadines | Similar name ("Saint"), neighboring island, close area code |
| +1 767 | Dominica | Area code close to 758, also in the Windward Islands |
| +1 473 | Grenada | Another Windward Island, sometimes confused geographically |
| +596 | Martinique | Immediately north of Saint Lucia but uses French +596, not NANP |
The most common confusion is with Saint Vincent (+1 784). Both are "Saint" islands, both are in the Windward Islands chain, and their area codes are only 26 apart. If you're dialing from a contact list, double-check which "St." you're calling.
Time zone considerations
Saint Lucia uses Atlantic Standard Time (AST), which is UTC-4. The island does not observe daylight saving time, so the offset stays the same all year.
Time differences for callers
| Your location | Winter (Nov-Mar) | Summer (Mar-Nov) |
|---|---|---|
| New York / Toronto (ET) | Saint Lucia is 1 hour ahead | Same time |
| London (GMT/BST) | Saint Lucia is 4 hours behind | Saint Lucia is 5 hours behind |
| Los Angeles (PT) | Saint Lucia is 4 hours ahead | Saint Lucia is 3 hours ahead |
| Other Caribbean (AST) | Same time | Same time |
The practical upshot: if you're calling from the US East Coast during summer, there is no time difference at all. During winter, Saint Lucia is only 1 hour ahead. This makes scheduling calls easy compared to most international destinations.
Communication in Saint Lucia
Business hours
Offices typically run 8:00 AM to 4:30 PM, Monday through Friday. Government offices close for lunch from noon to 1:00 PM. Banks close at 3:00 PM. Saturday is a half-day for most shops (8:00 AM to 12:30 PM), and nearly everything is closed on Sunday.
Language
English is the official language and used in all business and government settings. Most Saint Lucians also speak Kweyol (Saint Lucian Creole), a French-based creole. You will hear Kweyol in casual conversation, at markets, and in rural areas. If you are calling someone in a professional context, English is fine. For personal calls, older relatives may be more comfortable in Kweyol.
Communication habits
WhatsApp is the dominant messaging platform. Most people use it for daily communication, including with businesses. Voice calls are still common for anything formal or when talking to older family members. The island's small size (about 180,000 people) means word-of-mouth and personal connections matter — a phone introduction from a mutual contact goes a long way in business settings.
The Saint Lucia diaspora
Where Saint Lucians have settled
The Saint Lucian diaspora is large relative to the island's population. Major communities exist in the UK (particularly London and the Midlands), the US (New York, Florida, and the Washington DC metro area), Canada (Toronto and Montreal), and the US Virgin Islands. Martinique and Guadeloupe also have Saint Lucian communities due to geographic and linguistic proximity.
Why they call home
Phone traffic to Saint Lucia spikes around Carnival (mid-July), Independence Day (February 22), Christmas, and the Saint Lucia Jazz Festival (now called "Saint Lucia Roots & Soul"). Families stay closely connected — remittances from the diaspora are a meaningful part of many households' income. Hurricane season (June through November) also drives calling surges, as people abroad check on family after storms. After Hurricane Tomas in 2010, phone lines were jammed for days.

Common mistakes to avoid
Assuming it's a domestic call from the US
The 1-758 format looks like any other US area code, but it is not. Your carrier bills it as an international call. If you're on an unlimited US calling plan, calls to Saint Lucia are not included. Check your international rates or use a VoIP service like CallSky to avoid surprises.
Dialing 011 before 1-758
From US/Canada, do not dial 011-1-758. The 011 international access code is for non-NANP countries. Since Saint Lucia is in the NANP, you dial it the same way you'd call any other area code: 1-758-XXX-XXXX. Adding 011 will likely result in an error or a wrong connection.
Confusing Saint Lucia with Saint Vincent
Saint Lucia is +1 758. Saint Vincent and the Grenadines is +1 784. Both start with "Saint" and both are in the same island chain. Mixing up the last two digits of the area code sends your call to the wrong island.
Forgetting Martinique uses a different system
Martinique is Saint Lucia's nearest neighbor to the north, but it uses +596 (the French system), not the NANP. If you need to call Martinique from Saint Lucia, that requires a different dialing format entirely.
