Which states share a border with Mexico?

The states that share a border with Mexico are Texas, California, New Mexico, and Arizona. This is significant because these four states have direct international borders with Mexico, facilitating trade, travel, and cultural exchange between the two countries.

Texas has the longest border with Mexico and serves as a major point for commerce and transportation. California also shares a significant border near cities like San Diego, which is a prominent entry point. New Mexico and Arizona connect to Mexico in the southwestern region, contributing to various economic and social interactions across the border. In contrast, the other options listed consist of states that are geographically located far from Mexico and thus do not share any borders with it.
