A courier service is a business that provides a convenient and efficient way to transport items, such as packages, documents, and goods, from one location to another. Couriers offer various levels of service, including same-day, next-day, and international delivery.

Couriers can deliver a wide range of items, including documents, letters, small packages, large parcels, perishable goods, medical supplies, and more. The specific items depend on the courier company's capabilities and the services they offer.

Customers typically contact a courier company to arrange a pickup and delivery. The courier collects the package from the sender's location and transports it to the recipient's location using various transportation modes like bicycles, motorcycles, cars, vans, trucks, or even airplanes for long-distance or international deliveries.

Using a courier service offers several benefits, including faster delivery times compared to traditional postal services, real-time tracking of packages, personalized services, secure handling of sensitive items, and often the option for expedited or same-day delivery.

Most courier services provide package tracking using unique tracking numbers. Customers can enter this number on the courier's website or app to get real-time updates on the package's location and delivery status.
