Overlay Area Code

This area code shares its geographic footprint with an overlay code, so the same cities are served by two area codes. Because overlays leave existing numbers untouched, this region's relief planning favors adding codes over redrawing boundaries.

The codes serving this same region: area code 458 (Eugene).

With prefix utilization already at 97.8%, numbering resources here are under sustained pressure — context that explains why overlays were introduced.

In service since: 05-Nov-1995

Demographics & Economics

Demographic Data Unavailable for Area Code 541

County-level demographic data is not available for this area code because NPA boundary polygons are not publicly distributed by NANPA. We use geographic boundary data from the Colorado Open Data Portal to map area codes to counties, which currently covers 194 of 376 geographic area codes.

Demographic statistics (population, income, education, poverty) require county-level aggregations from Census ACS data. Without a county mapping, these aggregations cannot be computed. We are actively seeking additional data sources to improve coverage.

Statistics are population-weighted aggregations from Census ACS 5-year estimates where county boundary data is available.See Sources for details.
