Grenada's telephone code

To call Grenada, use +1 473. The country calling code is 1, and 473 is the area code that identifies Grenada. A reference table of international calling codes lists Grenada with this combination. This guide reflects that table as consulted in November 2026.

Code 1 does not belong to Grenada alone. It is the shared calling code of the North American Numbering Plan (NANP), which covers the United States, Canada and a number of Caribbean territories. Within that plan, a three-digit area code identifies the destination. So 1 by itself does not identify Grenada. You need the full prefix 1 473.

Element | Value | What it identifies
Country calling code | 1 | The North American Numbering Plan as a whole
Area code | 473 | Grenada within that plan
International format | +1 473 [local number] | A Grenada number written for callers anywhere

How to dial a Grenada number

The exact sequence depends on where you are calling from. You did not say your location, so the formats below cover the main cases. In each one, [local number] stands for the subscriber number you were given, without the 473 area code.

From a mobile phone, from anywhere

Most mobile phones accept a plus sign in place of your country's international access prefix. Entering the number this way works no matter where you are, so it is the safest choice when you are unsure of the local prefix.

+1 473 [local number]

From a country outside the North American Numbering Plan

Dial your country's international access prefix, then 1, then 473, then the local number. The access prefix varies by country. 00 is common, but some countries use a different prefix. Check the prefix for your own country and phone service before dialing, because it is set by where you are calling from, not by Grenada.

[your international access prefix] 1 473 [local number]

Example where the access prefix is 00:
00 1 473 [local number]

From the United States, Canada or another NANP area

Grenada is part of the same numbering plan, so you do not need a separate international prefix. You dial 1, then the area code, then the local number, the same pattern used for calls between other NANP areas. Calls to Grenada can still be billed at international rates, so check with your carrier if cost matters.

1 473 [local number]

From within Grenada

The reference table supplied for this guide gives the calling code only. It does not say whether callers inside Grenada must include the 473 area code or can dial the local number alone. If you are calling from a phone in Grenada, confirm the local dialing rules with your operator.

Qualifications to keep in mind

  • Do not drop the 473 after dialing 1. Without it, the number may reach a different territory in the plan or fail to connect.
  • The plus sign stands for the international access prefix. Do not dial a prefix such as 00 and a plus sign together.
  • If a Grenada number was given to you with a leading 1 or +1 already included, do not add another 1.
  • This guide does not confirm the length of Grenada subscriber numbers, the rules for calling within Grenada, or any earlier codes Grenada may have used. Check these with a telecommunications operator or the national numbering authority if they matter to your call.
