What Legislative District Is ZIP 98112 In?
ZIP code 98112 is split across 2 Washington legislative districts — mostly the 43rd (98.1% of registered voters).
This is not a single-district place. Legislative boundaries are drawn from precincts, not postal or municipal ones, so they cut across both. The table below gives each district and the share of registered voters in it — the largest share is not the whole answer, and if you need your own district you need your address rather than your ZIP.

What this page will not compute
Each of these is a number a reader might reasonably expect. None of them follow from the records we hold, so we do not publish them.
- Your own district
- This place is split, and the split is by precinct rather than by street. Nothing on this page can tell an individual which district they are in — only an address lookup at the Secretary of State can, and this page is not a substitute for it.
- Where the ZIP boundary runs
- A ZIP code is a mail delivery route, not a mapped area, and the Postal Service redraws them without notice. The shares here come from matching precincts to the ZIP recorded on voter registrations, which is the best available join and not a boundary.
- Anyone not registered to vote
- Every share on this page is a share of registered voters. Residents who are not registered are not counted, so this is not a population figure and should not be read as one.
