The other area codes laid over 424
Area code 424 does not have Beverly Hills, California to itself. 1 other code — 310 — 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.
3104,332 blocks, 17 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 424 number and a 310 number from the same street can report different line types. Filtering Beverly Hills, California by area code needs all 2 of them.

Where 424 numbers are concentrated

Common questions
Where is area code 424?
Area code 424 covers Beverly Hills, California. It is not the only code there: 310 is an overlay on the same rate centres, so a Beverly Hills, California number can start with any of them.
Is a 424 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 424 the split runs 39% mobile, 41% landline and 19% VoIP, so landline is the most likely single answer.
Which carriers hold 424 numbers?
The largest holders are Onvoy, Bandwidth, T-Mobile USA, Inc.. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 424 numbers are there?
The code holds 4,955 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 424 covers on the order of 4,955,000 possible numbers — most of which have never been issued to anyone.
