What this record means

This row links US 57751 to Keystone, the available admin area, centroid coordinates, source accuracy, and source snapshot metadata.

Use it as a reference-data join for cleaning CRM rows, grouping operational reports, preparing territory QA, or checking whether an imported postal value has a source-backed match.

What the centroid can support

The latitude and longitude represent a postal centroid from the source snapshot. They are useful for approximate map previews, nearby-record review, deduplication checks, and distance-based QA.

They should not be treated as an official delivery boundary, address-level geocode, tax boundary, or service-area guarantee.
