The +1473 country code connects you to Grenada, the southernmost of the Windward Islands in the eastern Caribbean. Known as the "Spice Isle" for its nutmeg and mace production, Grenada is actually a tri-island state that includes Grenada itself, Carriacou, and Petite Martinique. About 113,000 people live across these islands, with the capital St. George's sitting on the southwestern coast. Because Grenada participates in the North American Numbering Plan (NANP), its numbers look like North American phone numbers with area code 473 — which catches some callers off guard when they realize the call is international.
Quick answer: Dial +1 (473) followed by 7 local digits. Total length: 11 digits (1 + 473 + 7-digit local number). There is no trunk prefix. Mobile numbers often start with 403–421 or 449–459. Landline numbers typically start with 228 or 230–240, 435–445.
How to call Grenada: quick reference
Since Grenada uses the NANP, callers from the US and Canada dial it like a domestic long-distance call. From other countries, you'll need your international access code before the full +1-473 number.

Mobile carriers in Grenada
Grenada's mobile market is a two-carrier duopoly, with both operators also offering fixed-line services in some form.
Flow (Liberty Latin America)
Flow is the legacy carrier, formerly Cable & Wireless and then LIME. It operates both the mobile network and the primary fixed-line infrastructure across all three islands. Flow also provides broadband and cable TV services.
Digicel
Digicel entered the Grenadian market in 2003 and quickly gained market share with competitive prepaid plans. It operates a mobile network across the islands and is particularly popular for affordable voice and data packages.
Don't confuse +1473 with nearby codes
Several Caribbean NANP codes start with +1-4XX, and Grenada's 473 can be confused with codes from nearby islands.
| Code | Country | How to tell apart |
|---|---|---|
| +1 (473) | Grenada | The code you want |
| +1 (784) | Saint Vincent & the Grenadines | "Grenadines" sounds similar to "Grenada" but it's a different country |
| +1 (758) | Saint Lucia | Neighbouring Windward Island, different code |
| +1 (246) | Barbados | Another eastern Caribbean island often grouped with Grenada |
The most common mix-up is between Grenada (+1-473) and Saint Vincent and the Grenadines (+1-784). The "Grenadines" in the latter refers to a chain of small islands shared between the two countries, but the phone systems are completely separate.
Time zone considerations
Grenada operates on Atlantic Standard Time (AST), which is UTC-4 year-round. The country does not observe daylight saving time.
| Your location | When it's noon in Grenada |
|---|---|
| New York (EST) | 11:00 AM (winter) / 12:00 PM (summer, EDT matches AST) |
| London (GMT/BST) | 4:00 PM (winter) / 5:00 PM (summer) |
| Dubai (GST) | 8:00 PM |
| Tokyo (JST) | 1:00 AM next day |
| Sydney (AEST/AEDT) | 3:00 AM next day (winter) / 2:00 AM next day (summer) |
During North American summer (EDT), New York and Grenada share the same clock time, which makes calling particularly convenient for the large Grenadian diaspora on the US East Coast.
Communication in Grenada
Business hours
Government offices and banks typically operate 8:00 AM to 4:00 PM, Monday through Friday. Shops often stay open until 5:00 or 6:00 PM and may open on Saturday mornings. Sunday is generally a rest day. The best window for business calls is 9:00 AM to 3:00 PM AST.
Language and etiquette
English is the official language and the standard for business communication. Grenadian Creole English is widely spoken in casual settings. Phone conversations tend to be warm and unhurried — expect a greeting and some pleasantries before getting to the point.
Network coverage
4G LTE coverage is available across most of Grenada's populated areas. Carriacou and Petite Martinique have mobile coverage but speeds can be slower. WhatsApp calling works well where data connectivity is available, but traditional voice calls remain common, especially for older generations and business contacts.
The Grenada diaspora
Where Grenadians have settled
The Grenadian diaspora is concentrated in a few places. The United States — particularly New York City, New Jersey, and South Florida — is home to the largest community. The United Kingdom, especially London, has a well-established Grenadian population dating back to the Windrush era. Canada (mainly Toronto) and Trinidad and Tobago also have notable communities.
Why they call home
Family ties drive most calls. Grenada's population is small enough that extended family networks stay close, and regular phone contact is the norm rather than the exception. Calls spike around carnival season (August), Independence Day (February 7), and major holidays like Christmas. Remittances make up a meaningful share of Grenada's economy, and phone calls usually go hand-in-hand with money transfers.
Dialing examples
Calling a mobile in St. George's from the US
Your friend's mobile number is 414-5678. From a US phone, dial: +1 (473) 414-5678. From a US landline: 1-473-414-5678. Since both the US and Grenada are in the NANP, no international access code is needed — just dial 1 + area code + number.
Calling a hotel landline in Grand Anse from the UK
The hotel's number is 444-1234. From a UK phone, dial: 00 1 473 444 1234. Or use the + format: +1 473 444 1234.
Calling a business in Carriacou from Germany
The office number is 443-7890. From Germany, dial: 00 1 473 443 7890. Or with the + prefix: +1 473 443 7890.
Calling within Grenada
For local calls within Grenada (including between Grenada, Carriacou, and Petite Martinique), just dial the 7-digit local number: 414-5678. No area code needed for local calls.
Common mistakes to avoid
Confusing Grenada with the Grenadines
Grenada (+1-473) and Saint Vincent and the Grenadines (+1-784) are separate countries with separate phone systems. Some of the Grenadine islands are politically part of Grenada (like Carriacou), but others belong to Saint Vincent. If your contact is on a Grenadine island, confirm which country it falls under before dialing.
Treating it as a domestic US call
Because Grenada uses the NANP, it looks identical to a US number. Your phone may even show it as a domestic call. But it's international — standard US domestic plans don't cover calls to Grenada, and you'll be billed international rates.
Adding a trunk prefix
Grenada has no trunk prefix. Don't add a 0 or any other digit before the local number. The number is always just 7 digits after the 473 area code.
Missing the +1 from outside North America
When calling from outside the NANP (Europe, Asia, etc.), you need the full +1 before 473. Dialing just +473 without the 1 won't connect.
