Area code 483
Area code 483 covers Montgomery, Alabama. We hold 26 allocated blocks for it across 4 rate centres, split 0% mobile, 57% landline and 43% VoIP.
The other area codes laid over 483
Area code 483 does not have Montgomery to itself. 1 other code — 334 — serves the same rate centres, laid over the same ground rather than dividing it. That is an overlay: a new code added when the old one ran out of numbers, covering the same streets. Two neighbours can hold different area codes, so the code says roughly when a number was issued rather than where it sits.
3345,251 blocks, 97 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 483 number and a 334 number from the same street can report different line types. Filtering Montgomery by area code needs all 2 of them.
483 is not confined to Montgomery itself: its blocks sit across 4 rate centres, named in the table below.
Alabama is split across 7 area codes — 256, 205, 334, 251, 938, 483 and others. By allocated blocks 483 is the 7th largest of them, holding 0% of the Alabama total.
Where 483 numbers are concentrated
Rate-centre names are reproduced as NANPA records them. The agency truncates them to ten characters, so longer names appear shortened elsewhere on this site.
| Rate centre | Blocks | Share of 483 |
|---|---|---|

| Auburn | 4 | 15% |

Carriers holding the most 483 blocks
Ahoi Llc8 blocks
Wide Voice, Llc6 blocks
Onvoy6 blocks
Opentact Inc.4 blocks
Intrado Communications Llc2 blocks
The largest holder, Ahoi Llc, has 31% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 483 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 483?
Area code 483 covers Montgomery, Alabama. It is not the only code there: 334 is an overlay on the same rate centres, so a Montgomery, Alabama number can start with any of them.
Is a 483 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 483 the split runs 0% mobile, 57% landline and 43% VoIP, so landline is the most likely single answer.
Which carriers hold 483 numbers?
The largest holders are Ahoi Llc, Wide Voice, Llc, Onvoy. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 483 numbers are there?
The code holds 26 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 483 covers on the order of 26,000 possible numbers — most of which have never been issued to anyone.
