Area code 580

Where area code 580 is

580 is one of 5 geographic area codes serving Oklahoma; NANPA records its in-service date as November 1, 1997. It is not part of an overlay, so every number in its territory starts with 580. It is in the Central time zone. The places with the most assigned exchanges include Lawton, Enid, Ardmore, Ada, and Durant. By population, its largest named places are Lawton, Enid, Ardmore, Ponca City, and Duncan.

Places served by 580

580 holds 28% of the 2,661 central office codes assigned in Oklahoma, the 3rd most of the state's 5 codes. 207 Census places could be matched to rate centers with 580 exchanges; the most populous are Lawton (90,027), Enid (50,519), Ardmore (25,064), and Ponca City (24,234). Each place page lists the exact prefixes and carriers for that town.

Ten-digit and seven-digit dialing in 580

According to NANPA's dialing-plan data, local calls within 580 are dialed as seven digits and toll calls as 1 plus ten digits. Seven-digit local dialing is still permitted here, but customers calling from other area codes, and every mobile contact list, use all ten digits.

Who holds 580 exchanges

51 carriers hold the 740 central office codes assigned in 580. Southwestern Bell has the most, with 154 (21%). 500 of the codes (68%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. The code holder is not necessarily the carrier serving a given number today, since numbers can be ported between providers.

Rate centers and towns in 580

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 580 has codes in 255 rate centers. Rate center names in the file are abbreviations; where one matches a Census place, the table links to that city's local-number page.

580 code assignments over time

An area code has 800 possible central office codes that start with 2 through 9, a few of which are reserved (such as N11 service codes and 555). 740 are assigned in 580, 93% of 800. 86 were assigned in 2020 or later. NANPA reports relief planning in progress for 580, the process used to add a new area code when one is projected to run out of codes.

A local 580 number on Callata

For $99 a month, Callata puts a team of up to 5 on one plan ($20 for each person after that): up to 3 local numbers, unlimited inbound calls, a pooled allowance of 1,500 outbound US and Canada minutes per user, browser and cell calling, voicemail transcription with urgency triage, recorded calls with AI summaries and business-hours routing, with E911 on every number.

Porting a number you already use in area code 580 is free, and business texting is available once the carrier registration (10DLC) is approved; the registration carries a one-time $49 fee. Which specific numbers are open in a given area code depends on carrier inventory at the time you sign up.

AI agents are optional: an AI receptionist or scheduler can pick up when the team is busy or closed, take a message, send a text or email, or transfer the call. They draw on prepaid AI minutes ($0.25/minute), disclose that they are AI, and outbound AI calls require prior consent and are limited to 8am–9pm.
