Border crossing is the movement of people or goods from one country or region into another. It takes place at official entry points such as land borders, airports, and seaports. Travelers, migrants, refugees, and transport workers are involved in these movements. Border officials and customs officers manage the process.

Border crossings happen every day in modern travel and trade systems around the world. People may cross borders for work, tourism, or relocation. Goods are also transported across borders for trade between countries.

At many border crossings, checks are carried out on identity, travel documents, luggage, or goods. These checks follow rules set by each country. Border crossing is part of how countries manage movement between regions.
