Area code 340 calling hours: can you call now?

Area code 340 serves Chtamstths, Chnstdstcr, and St. Croix in U.S. Virgin Islands. It is on Atlantic time. There is no daylight saving time here, so the local clock does not change in March or November — but its gap to the rest of the country does.

Debt collection: federal — Presumed convenient 8 a.m.-9 p.m. local time at the consumer's location, any day. U.S. Virgin Islands: no separate hour rule.
Telemarketing: federal — 8 a.m.-9 p.m. local time at the called party's location, any day. U.S. Virgin Islands: no separate hour rule.

Calling-hour rules for 340

Hours are local time at the person you are calling. When federal and U.S. Virgin Islands rules differ, the narrower window governs; the live check applies every row at once.

U.S. Virgin Islands

No separate state hours; the federal window applies.

Also in U.S. Virgin Islands

No territory-specific calling-hour rule found. 12A V.I.C. ch. 6 regulates telemarketing (e.g., § 310 free-trial invoices) without hours; debt collection is addressed only through general deceptive/unconscionable-practice provisions (12A V.I.C. §§ 101, 303). Federal rules apply. Confidence low: full Title 12A text not opened.

Exchanges and time zones

Every assigned exchange in 340 sits in Atlantic time, so the area code alone settles the zone for a landline. Rate centers by exchange count:

Rate center	Exchanges
Chtamstths, VI	42
Chnstdstcr, VI	7
St. Croix, VI	7
Frkstdstcr, VI	2

340 has no overlay codes.

Why area code alone is not enough

Mobile numbers travel with their owners, and a ported number keeps its original 340 area code and exchange. A 340 number tells you where the line was assigned, not where the person is today.
Under Regulation F, when you know of more than one location for a consumer — a mailing address in one zone, an area code in another — the time must be convenient in every one of them. Use the address-state field above to add the zones you know about.
Call only when the window is open in every location you know about, and stop calling at times the consumer tells you are inconvenient, whatever the clock says.

Questions

What time can you call area code 340?

Area code 340 is in U.S. Virgin Islands, on Atlantic time. Debt collection: federal — Presumed convenient 8 a.m.-9 p.m. local time at the consumer's location, any day. U.S. Virgin Islands: no separate hour rule. Telemarketing: federal — 8 a.m.-9 p.m. local time at the called party's location, any day. U.S. Virgin Islands: no separate hour rule.

What time zone is area code 340?

Area code 340 is entirely in Atlantic time. There is no daylight saving time here, so the local clock does not change in March or November — but its gap to the rest of the country does.

Can a debt collector call a 340 number on Sunday?

Neither federal law nor U.S. Virgin Islands sets separate Sunday hours for debt collection; the 8 a.m.–9 p.m. local-time window applies, and a consumer can tell a collector that Sunday is inconvenient.

Is the 340 area code enough to know the person's local time?

No. Mobile numbers move with their owners and ported numbers keep their area code, so a 340 number may belong to someone in another time zone. If you know other locations for the person, the call should fit the window in all of them.
