Calling-hour rules for 870
Hours are local time at the person you are calling. When federal and Arkansas 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. |
| Arkansas | Presumed convenient 8 a.m.-9 p.m. local time at the consumer's location, any day (mirrors federal law). Every day 8:00 a.m.–9:00 p.m. Ark. Code Ann. § 17-24-504(a)(1)
Default presumption; prior consumer consent or knowledge that a time is inconvenient changes it. | No separate state hours; the federal window applies. |
Also in Arkansas
- Arkansas telemarketing law requires checking the state do-not-call database and complying with the FTC Do-Not-Call rule (Ark. Code Ann. § 4-99-405); no separate state calling-hours rule was found, so the federal 8 a.m.-9 p.m. window applies.

Why area code alone is not enough
- Mobile numbers travel with their owners, and a ported number keeps its original 870 area code and exchange. An 870 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 870?

Arkansas: Presumed convenient 8 a.m.-9 p.m. local time at the consumer's location, any day (mirrors federal law). Telemarketing: federal — 8 a.m.-9 p.m. local time at the called party's location, any day. Arkansas: no separate hour rule.
What time zone is area code 870?
Area code 870 is entirely in Central time. Clocks move for daylight saving time in March and November.
Can a debt collector call an 870 number on Sunday?
Sunday is not singled out: Arkansas'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 870 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 an 870 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.
