The other area codes laid over 564
Area code 564 does not have Bremerton to itself. 1 other code — 360 — 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.
3606,020 blocks, 75 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 564 number and a 360 number from the same street can report different line types. Filtering Bremerton by area code needs all 2 of them.
564 is not confined to Bremerton itself: its blocks sit across 32 rate centres, named in the table below.

Where 564 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Mt Vernon and Pt Angeles are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

The largest holder, Onvoy, has 19% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 564 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 564?
Area code 564 covers Bremerton, Washington. It is not the only code there: 360 is an overlay on the same rate centres, so a Bremerton, Washington number can start with any of them.
Is a 564 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 564 the split runs 46% mobile, 34% landline and 19% VoIP, so mobile is the most likely single answer.
Which carriers hold 564 numbers?
The largest holders are Onvoy, Verizon Wireless, 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 564 numbers are there?
The code holds 892 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 564 covers on the order of 892,000 possible numbers — most of which have never been issued to anyone.
