Area code 530 is centred on Marysville, California. We hold 6,543 allocated blocks for it across 131 rate centres, split 34% mobile, 46% landline and 20% VoIP.
The other area codes laid over 530
Area code 530 does not have Marysville to itself. 1 other code — 837 — 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.
83719 blocks, 7 rate centres, mostly VoIP
Each holds its own blocks and its own carrier mix, so a 530 number and a 837 number from the same street can report different line types. Filtering Marysville by area code needs all 2 of them.
530 is not confined to Marysville itself: its blocks sit across 131 rate centres, named in the table below.

Where 530 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Plvl West and Grvy Main are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 530 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 530?
Area code 530 covers Marysville, California. It is not the only code there: 837 is an overlay on the same rate centres, so a Marysville, California number can start with any of them.
Is a 530 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 530 the split runs 34% mobile, 46% landline and 20% VoIP, so landline is the most likely single answer.
Which carriers hold 530 numbers?
The largest holders are Onvoy, Pacific Bell, Verizon Wireless. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 530 numbers are there?
The code holds 6,543 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 530 covers on the order of 6,543,000 possible numbers — most of which have never been issued to anyone.
