Area code 602 calling hours: can you call now?
Area code 602 serves Phoenix in Arizona. It is on Mountain (no DST) 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. Arizona: no separate hour rule.
- Telemarketing: federal — 8 a.m.-9 p.m. local time at the called party's location, any day. Arizona: 8 a.m.-9 p.m. local time, any day (Arizona adopts the federal calling-time rules by reference).

Calling-hour rules for 602
Hours are local time at the person you are calling. When federal and Arizona 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. |
| Arizona | No separate state hours; the federal window applies. | 8 a.m.-9 p.m. local time, any day (Arizona adopts the federal calling-time rules by reference). Every day 8:00 a.m.–9:00 p.m.
The statute makes it unlawful to 'initiate an outbound call except as provided in' 47 CFR 64.1200 or 16 CFR 310.4, which is where the 8 a.m.-9 p.m. window lives; Arizona adds no Sunday or holiday restriction. |
Also in Arizona
- Arizona collection agencies may contact debtors by telephone 'only during reasonable hours' (Ariz. Admin. Code R20-4-1512(A)); the rule sets no specific hours, so the federal 8 a.m.-9 p.m. default is the practical benchmark.
Exchanges and time zones
Every assigned exchange in 602 sits in Mountain (no DST) time, so the area code alone settles the zone for a landline. Rate centers by exchange count:
| Rate center | County | Exchanges |
|---|---|---|
| Phoenix, AZ | Maricopa | 744 |

Why area code alone is not enough
- Mobile numbers travel with their owners, and a ported number keeps its original 602 area code and exchange. A 602 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 602?
Area code 602 is in Arizona, on Mountain (no DST) time. Debt collection: federal — Presumed convenient 8 a.m.-9 p.m. local time at the consumer's location, any day. Arizona: no separate hour rule. Telemarketing: federal — 8 a.m.-9 p.m. local time at the called party's location, any day. Arizona: 8 a.m.-9 p.m. local time, any day (Arizona adopts the federal calling-time rules by reference).
What time zone is area code 602?
Area code 602 is entirely in Mountain (no DST) 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 602 number on Sunday?
Neither federal law nor Arizona 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 602 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 602 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.
