03048

03048 is a ZIP code in the United States, a postal designation used by the United States Postal Service to identify a geographic area for mail delivery. ZIP codes are primarily a tool for sorting and routing mail and do not correspond exactly to city or county boundaries.

Geographically, the 03048 designation covers parts of southern New Hampshire. The area comprises a mixture of residential neighborhoods and commercial zones, and its precise boundaries may cross town lines due to the way postal routes are organized. The ZIP code boundaries can change over time as routes are reorganized or expanded.

Historically, ZIP codes were introduced by the USPS in 1963 to improve mail efficiency. The 03048 code would have been assigned as part of later expansions and updates to the ZIP system. In daily use, many addresses within 03048 will also be identified by ZIP+4 codes, which provide even more specific routing for mail delivery.

Demographically and economically, data at the ZIP code level are used for planning and statistical purposes, such as market analysis and local services. However, ZIP code boundaries are not equivalent to municipal boundaries, and population figures or census data attributed to 03048 may span multiple towns or city jurisdictions.

In summary, 03048 is a United States ZIP code serving a portion of southern New Hampshire. It functions mainly as a mail delivery boundary and as a geographic unit for various administrative and planning purposes, with boundaries that can evolve over time.
