Why area code alone is not enough

Mobile numbers travel with their owners, and a ported number keeps its original 973 area code and exchange. A 973 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 973?

Area code 973 is in New Jersey, on Eastern time. Debt collection: federal — Presumed convenient 8 a.m.-9 p.m. local time at the consumer's location, any day. New Jersey: no separate hour rule. Telemarketing: federal — 8 a.m.-9 p.m. local time at the called party's location, any day. New Jersey: No unsolicited sales calls between 9 p.m. and 8 a.m. local time, any day.

What time zone is area code 973?

Area code 973 is entirely in Eastern time. Clocks move for daylight saving time in March and November.

Can a debt collector call a 973 number on Sunday?

Neither federal law nor New Jersey 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 973 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 973 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.
