Key Facts

San Marcos is a district located in the Huari Province of the Ancash Region in Peru. Situated in the central highlands of Peru, San Marcos occupies a strategic position within the Callejón de Conchucos valley, surrounded by the dramatic peaks of the Cordillera Blanca mountain range to the west and the Cordillera Huayhuash to the east. The district covers approximately 527 square kilometers of rugged Andean terrain characterized by high-altitude landscapes, glacial valleys, and traditional Quechua-speaking communities. With an estimated population of around 15,000 residents, San Marcos serves as an important administrative and commercial center for the surrounding rural communities. The district is divided into several smaller populated centers and annexes, including the town of San Marcos proper and numerous outlying villages that dot the mountainous landscape. The economy is primarily based on agriculture, with potato, corn, and quinoa cultivation dominating the fertile valley floors, while livestock raising, particularly alpaca and sheep, thrives in the higher elevations. San Marcos provides essential postal and administrative services for residents seeking to access information about its various populated centers and their corresponding postal codes.
