The towns inside area code 830
Area code 830 is not a city code. It covers 96 separate rate centres — billing areas, each its own local calling zone. The largest of them are named in the table below.
That matters twice over. A call between two 830 numbers is not necessarily a local call, because they can sit in different rate centres. And a code this wide narrows a subscriber to a region rather than a town.
Texas is split across 28 area codes — 346, 832, 469, 210, 956, 830 and others. By allocated blocks 830 is the 17th largest of them, holding 3% of the Texas total.
Where 830 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Newbranfls and Marble Fls are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

The largest holder, AT&T Wireless, has 16% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 830 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.

Common questions
Where is area code 830?
Area code 830 is centred on New Braunfels, Texas and spans 96 rate centres, so it covers a region rather than a town.
Is a 830 number a mobile or a landline?
It can be either, and the digits do not say which. North American mobile and landline numbers share the same ranges, so the answer comes from the carrier holding the block. In 830 the split runs 40% mobile, 44% landline and 17% VoIP, so landline is the most likely single answer.
Which carriers hold 830 numbers?
The largest holders are AT&T Wireless, Onvoy, Southwestern Bell. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 830 numbers are there?
The code holds 4,001 allocated blocks in our copy of the numbering plan. A block is 1,000 or 10,000 consecutive numbers depending on how deeply it has been pooled, so 830 covers on the order of 4,001,000 possible numbers — most of which have never been issued to anyone.
