When a listing near Firth mentions a lot number, look up the Blackfoot plat map it refers to. This Blackfoot guide covers: where to request a copy, plat versus tax map, and what to look for on the sheet.
Who keeps the Blackfoot plat map
For a subdivision near Basalt, the deed usually cites the plat; that makes the request quick.
Opening the official parcel viewer
Property in and around Aberdeen appear on the Idaho statewide Parcels layer in ArcGIS Map Viewer, which opens without registering. Closer to Shelley, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a tract near Shelley, the parcel card usually lists the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Taking the map into the field
Most viewers work in a phone browser, useful out on a road near Firth, though signal can drop in rural spots. A screenshot of the parcel near Firth with its ID keeps working without signal.
Blackfoot, ID: the basics
Blackfoot is part of Bingham County, Idaho, so its parcels are on the county's map. As the county seat, Blackfoot hosts the courthouse, so deeds and plats are filed in town. For a parcel near Aberdeen, city or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Acreage past the city limits out by Shelley generally answers to county rules rather than the town's.
Recorded plat or GIS layer
The tax map on the Idaho statewide Parcels layer in ArcGIS Map Viewer is a summary, whereas the plat carries surveyed dimensions.
Where the recorded documents are
Before you sign anything, get the recorded deed through the County Recorder (the county clerk serves as recorder); the parcel map near Shelley only summarizes it. Long-held tracts around Aberdeen may sit on several deeds, so a title company can sort it out on a real sale.
Amended plats
An amended plat may change lots around Firth, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
What a plat shows
For a parcel near Basalt, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
When a parcel crosses a boundary
Bingham County meets Bannock County, Blaine County, Bonneville County, Butte County, and Caribou County, and each of those keeps its own parcel map. Acreage along the edge near Shelley can show up across two assessors' files, so look at the neighboring map before you assume the acreage. The Platbookmapper state page links each bordering county map for Idaho.
Metes and bounds instead
Rural land near Firth that was never subdivided may have no plat at all; the deed and any recorded survey describe it instead.
Who handles what
Recorded documents for a parcel near Firth come from the County Recorder (the county clerk serves as recorder), sometimes only in person. Zoning, permits and septic questions near Shelley need the planning or permitting office, and the answer depends on jurisdiction.

Keep the legal description for land near Shelley for any title or survey request.
Online indexes and office visits

The acreage figure is an assessed number; only a licensed surveyor can set the real lines for a parcel near Shelley. For acreage around Aberdeen, records update in batches, so a deed recorded last month can take weeks to appear.
