Virgin Islands Country Code

How do I dial mobiles vs landlines in the U.S. Virgin Islands

The U.S. Virgin Islands (USVI) uses the North American Numbering Plan (NANP), so its calling setup looks like a U.S. number: country code +1 with area code 340. Local USVI numbers are 7 digits, and from the U.S./Canada you typically dial 1 + 340 + XXX-XXXX. From outside NANP countries, dial +1 340 XXX XXXX. 

There’s no special “mobile vs landline” dial rule—both mobiles and landlines use the same +1 340 format. The difference is in the exchange (the next three digits after 340), which can indicate the underlying carrier type (mobile/landline/VoIP) rather than the island itself. For best deliverability (roaming, iMessage/WhatsApp, verification SMS), store all USVI numbers in E.164 format as +1 340 XXX XXXX. The first digits after 340 (the NXX exchange) can hint at the original carrier, but exchanges can change ownership and many numbers are now VoIP. If you need the current carrier (billing/routing), use a live carrier-lookup rather than relying on the prefix alone.
