Area code 830

Where area code 830 is

830 is one of 29 geographic area codes serving Texas; NANPA records its in-service date as July 7, 1997. It is not part of an overlay, so every number in its territory starts with 830. It is in the Central time zone. The places with the most assigned exchanges include New Braunfels, Del Rio, Seguin, Kerrville, and Eagle Pass. By population, its largest named places are San Antonio, New Braunfels, Seguin, Del Rio, and Eagle Pass.

Where 830 numbers are local

830 holds 3.1% of the 16,097 central office codes assigned in Texas, the 17th most of the state's 29 codes. 53 Census places could be matched to rate centers with 830 exchanges; the most populous are San Antonio (1.5 million), New Braunfels (116,000), Seguin (38,789), and Del Rio (34,678). Each place page lists the exact prefixes and carriers for that town.

Ten-digit and seven-digit dialing in 830

According to NANPA's dialing-plan data, local calls within 830 are dialed as ten digits (area code plus number) and toll calls as 1 plus ten digits. Because local calls need the area code, business cards, signage and website copy should always show the full ten-digit number. NANPA's dialing-plan note for this code reads: "1+10 digit permissible at service provider discretion."

Who holds 830 exchanges

47 carriers hold the 496 central office codes assigned in 830. Southwestern Bell has the most, with 71 (14%). 406 of the codes (82%) 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.

Local calling areas in 830

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 830 has codes in 96 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.

Number supply in 830

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). 496 are assigned in 830, 62% of 800. 79 were assigned in 2020 or later.

Getting a 830 number for your business

Callata Office costs $99 per month for up to 5 people, and each additional user is $20 a month. That covers up to 3 local numbers, calling from a browser or your cell, transcribed voicemail, recorded calls with AI summaries, after-hours routing and E911 on each number.

Porting a number you already use in area code 830 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.
