Calling-hour rules for 336
Hours are local time at the person you are calling. When federal and North Carolina rules differ, the narrower window governs; the live check applies every row at once.
| Rule set | Debt collection | Telemarketing |
|---|---|---|
| Federal | Presumed convenient 8 a.m.-9 p.m. local time at the consumer's location, any day. Every day 8:00 a.m.–9:00 p.m. 15 U.S.C. § 1692c(a)(1) · 12 CFR § 1006.6(b)(1)(i) (Regulation F) · Reg F Official Interpretation, comment 6(b)(1)(i)-2 (consumer's location) · 12 CFR § 1006.14(b)(2)
No federal Sunday or holiday ban, but a consumer's statement that a day or time is inconvenient makes calls then unlawful. The 8-9 window is a default presumption that the consumer's prior consent (given directly to the collector) or a court can override. | 8 a.m.-9 p.m. local time at the called party's location, any day. Every day 8:00 a.m.–9:00 p.m. 47 CFR § 64.1200(c)(1) (TCPA rules) · 16 CFR § 310.4(c) (Telemarketing Sales Rule)
TSR § 310.4(c) allows calls outside 8-9 with the person's prior consent; the TCPA time rule in § 64.1200(c)(1) has no consent exception for telephone solicitations as defined. |
| North Carolina | No fixed hours; state law bars calls at times known to be outside the person's normal waking hours, and it also covers creditors collecting their own debts. Every day 8:00 a.m.–9:00 p.m. N.C. Gen. Stat. § 75-52(3) · N.C. Gen. Stat. § 58-70-100(3)
The state standard is 'times known to be times other than normal waking hours of the person'. It has no clock hours and is modeled here as the federal 8 a.m.–9 p.m. window. It matters mainly because it reaches first-party creditors, whom the FDCPA does not cover. | 8 a.m.–9 p.m., any day. Every day 8:00 a.m.–9:00 p.m.
The statute does not say whose local time; treat as the called party's. H.B. 936 (2025–26), which would extend the hours limit to robocalls and texts and require prior express written consent, was in conference committee as of June 24, 2026 and is not enacted. |

Why area code alone is not enough
- Mobile numbers travel with their owners, and a ported number keeps its original 336 area code and exchange. A 336 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 336?
Area code 336 is in North Carolina, on Eastern time. Debt collection: federal — Presumed convenient 8 a.m.-9 p.m. local time at the consumer's location, any day. North Carolina: No fixed hours; state law bars calls at times known to be outside the person's normal waking hours, and it also covers creditors collecting their own debts. Telemarketing: federal — 8 a.m.-9 p.m. local time at the called party's location, any day. North Carolina: 8 a.m.–9 p.m., any day.
What time zone is area code 336?
Area code 336 is entirely in Eastern time. Clocks move for daylight saving time in March and November.
Can a debt collector call a 336 number on Sunday?
Sunday is not singled out: North Carolina's debt-collection hours are every day 8:00 a.m.–9:00 p.m., and the federal 8 a.m.–9 p.m. window also applies. A consumer can still tell a collector that Sunday is inconvenient.
Is the 336 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 336 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.
