Grenada Phone Number validator
How the phone number format works
- Format
- Grenada phone number in national or international (+1) format
- Example
- +14734031234
Things to watch for
- Accepts national or international (E.164, e.g. +1...) format
- Validated with Google's libphonenumber; confirms the number is possible/valid for this country, not that it is currently assigned or reachable
^[+]?[0-9 ()\-]{6,}$Grenada runs on area code 473 within the standard 10-digit NANP +1 plan, the same numbering shape used across most of the English-speaking Caribbean. Known as the “Spice Isle” for its outsized nutmeg and mace production, Grenada also holds a distinction among Eastern Caribbean citizenship-by-investment nations: a bilateral E-2 investor treaty with the United States, giving Grenadian citizens a path to US E-2 visas that citizens of several neighboring CBI countries don’t have.
How this validator works
Enter the number in local form (473-403-1234) or full international form (+14734031234); this tool checks the digit count and confirms the area code matches 473, Grenada’s assigned NANP code, using Google’s libphonenumber entirely client-side. As with any NANP territory, it’s the area code — not the shared +1 prefix — that actually pins a number to Grenada rather than to one of the dozens of other countries and territories inside the same plan.
What a pass doesn’t tell you
A pass confirms the number carries the genuine Grenada area code and a plausible local number — it does not confirm the line is connected, ported, or still held by whoever gave it to you.
Scope: format and area-code-origin validation only, for catching a mistyped digit before a number reaches a CRM or dialer — not a substitute for a carrier lookup.

phone number FAQ
Why is Grenada called the Spice Isle?
Grenada is one of the world's largest nutmeg producers relative to its size — the crop even appears on the national flag — a nickname with no bearing on its phone numbering, which runs on standard NANP +1 area code 473 like its Eastern Caribbean neighbors.
Did the US ever invade Grenada?
Yes — in 1983, the US led a multinational invasion codenamed Operation Urgent Fury after a coup toppled the government, a significant moment in Grenada's post-independence history that's unrelated to its later, unrelated adoption of a citizenship-by-investment program.
Does a valid 473 number confirm the SIM is currently active?
No. It only confirms the area code and 7-digit local number match a real Grenada NANP pattern — not that the line is active or reachable, which needs a carrier-side lookup this tool doesn't perform.
