Area code 620 calling hours: can you call now?

Area code 620 serves Hutchinson, Garden City, and Dodge City in Kansas. It spans Central and Mountain time, so the exchange matters. Clocks move for daylight saving time in March and November.

Turn on JavaScript for the live check. The rules table below lists every window that applies to 620.

Calling-hour rules for 620

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

Rule setDebt collectionTelemarketing
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)

  • Call-frequency presumption: a collector is presumed to comply with the harassment ban if it places no more than 7 calls to a person about a particular debt within 7 consecutive days, and no call within 7 days after a telephone conversation with that person about the debt; exceeding either is presumed a violation (12 CFR § 1006.14(b)(2)).
  • Conflicting location information: if the collector's information indicates the consumer may be in more than one place (e.g. an Eastern-zone area code and a Pacific-zone address), it complies only by calling at a time convenient in all of those locations (Reg F comment 6(b)(1)(i)-2).
  • A collector may not call at any time it knows or should know is inconvenient to the consumer (e.g. after the consumer says so), regardless of the 8 a.m.-9 p.m. default (15 U.S.C. § 1692c(a)(1); Reg F comment 6(b)(1)-1).

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)

  • No telephone solicitation to a number on the National Do Not Call Registry absent an established business relationship or the consumer's signed written permission (47 CFR § 64.1200(c)(2); 16 CFR § 310.4(b)(1)(iii)(B)).
  • Autodialed or artificial/prerecorded-voice telemarketing calls to wireless numbers, and prerecorded telemarketing calls to residential lines, require the called party's prior express written consent (47 CFR § 64.1200(a)(2)-(3)).
  • Sellers must honor company-specific do-not-call requests (47 CFR § 64.1200(d); 16 CFR § 310.4(b)(1)(iii)(A)).

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.

KansasNo separate state hours; the federal window applies.No separate state hours; the federal window applies.

Also in Kansas

  • Kansas's no-call law (K.S.A. 50-670, 50-670a) requires caller identification, prompt termination on a negative response and scrubbing against the National DNC Registry every 30 days, but sets no calling hours; the federal window applies.
  • Kansas has no debt-collection calling-hours statute.

Exchanges and time zones

Area code 620 spans Central and Mountain time. The exchange — the three digits after the area code — maps to a rate center, and the rate center sets the zone. Enter the number in the check above to use it; without one, the check requires the window to be open in every zone 620 covers.

Questions

What time can you call area code 620?

Area code 620 is in Kansas, on Central and Mountain time. Debt collection: federal — Presumed convenient 8 a.m.-9 p.m. local time at the consumer's location, any day. Kansas: no separate hour rule. Telemarketing: federal — 8 a.m.-9 p.m. local time at the called party's location, any day. Kansas: no separate hour rule.

What time zone is area code 620?

Area code 620 spans Central and Mountain time. The exchange (the three digits after the area code) decides which; when it is unknown, a call should fit the window in every zone the area code covers.

Can a debt collector call a 620 number on Sunday?

Neither federal law nor Kansas 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 620 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 620 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.
