Area code 405
Area code 405 is centred on Oklahoma City. We hold 6,221 allocated blocks for it across 93 rate centres, split 43% mobile, 42% landline and 15% VoIP.
The other area codes laid over 405
Area code 405 does not have Oklahoma City to itself. 1 other code — 572 — 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.
5721,033 blocks, 52 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 405 number and a 572 number from the same street can report different line types. Filtering Oklahoma City by area code needs all 2 of them.
405 is not confined to Oklahoma City itself: its blocks sit across 93 rate centres, named in the table below.
Oklahoma is split across 5 area codes — 405, 918, 580, 539, 572. By allocated blocks 405 is the largest of them, holding 32% of the Oklahoma total.
Where 405 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Midwest Cy and Pauls Vly are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

The largest holder, Southwestern Bell, 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 405 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 405?
Area code 405 covers Oklahoma City. It is not the only code there: 572 is an overlay on the same rate centres, so a Oklahoma City number can start with any of them.
Is a 405 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 405 the split runs 43% mobile, 42% landline and 15% VoIP, so mobile is the most likely single answer.
Which carriers hold 405 numbers?
The largest holders are Southwestern Bell, AT&T Wireless, Onvoy. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 405 numbers are there?
The code holds 6,221 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 405 covers on the order of 6,221,000 possible numbers — most of which have never been issued to anyone.
