1-473 Country Code: Grenada (+1-473)

Most failed calls to Grenada come from one of four mistakes, not from network problems. The most common is mishandling the country code itself: Grenada uses +1-473 with no trunk prefix to remove, so you dial it as-is. The most frequent error is adding a leading 0 by habit — there is none in the Grenada number plan.

The second is misreading the area code on landline numbers — Grenada numbers may have variable formatting depending on the carrier and city, so confirm the area code with the recipient before dialing. The third is dialing during off-hours — Grenada uses local business hours and consumer phones are usually answered between 8 AM and 9 PM local time. The fourth and most expensive mistake is assuming your US carrier's WiFi calling feature makes the call cheap. It does not — see WiFi calling vs VoIP for international calls for why.

For scam-call awareness: +1-473 is the legitimate Grenada country code, and most unsolicited calls from +1-473 numbers are legitimate calls from Grenada-based businesses, hospitals, family members, or call centers serving US customers. Caller-ID spoofing exists, so if a call from a +1-473 number claims to be from a US government agency, your bank, or the IRS, hang up and call the agency back on its published number. Real authorities never demand payment over the phone.
