Courier
A courier is a person or organization that delivers a message, package or letter from one place or person to another place or person. Typically, a courier provides their courier service on a commercial contract basis; however, some couriers are government or state agency employees (for example: a diplomatic courier). Duties and functions
Couriers are distinguished from ordinary mail services by features such as speed, security, tracking, signature, specialization and individualization of express services, and swift delivery times, which are optional for most everyday mail services. As a premium service, couriers are usually more expensive than standard mail services, and their use is normally limited to packages where one or more of these features are considered important enough to warrant the cost. Courier services operate on all scales, from within specific towns or cities, to regional, national and global services. Large courier companies include DHL, DTDC, FedEx, EMS International, TNT, UPS, India Post, J&T Express and Aramex. These offer services worldwide, typically via a hub and spoke model. Couriers services utilizing courier software provide electronic proof of delivery and electronic tracking details. Before the industrial era

In ancient history, messages were hand-delivered using a variety of methods, including runners, homing pigeons and riders on horseback. Before the introduction of mechanized courier services, foot messengers physically ran miles to their destinations. Xenophon attributed the first use of couriers to the Persian prince Cyrus the Younger. Famously, the Ancient Greek courier Pheidippides is said to have run 26 miles from Marathon to Athens to bring the news of the Greek victory over the Persians in 490 BCE. The long-distance race known as a marathon is named for this run. Hezekiah 
Judah's king, Hezekiah, dates between 200-400 BCE, where several couriers brought letters throughout the land of Judah and Israel (cf. 2 Chron 30 ESV). Anabasii 
Starting at the time of Augustus, the ancient Greeks and Romans made use of a class of horse and chariot-mounted couriers called anabasii to quickly bring messages and commands from long distances. The word anabasii comes from the Greek ἀνάβασις(anábasis, "ascent, mounting"). They were contemporary with the Greek hemeredromi, who carried their messages by foot. In Roman Britain, Rufinus made use of anabasii, as documented in Saint Jerome's memoirs (adv. Ruffinum, l. 3. c. 1. ): "Idcircone Cereales et Anabasii tui per diversas provincias cucurrerunt, ut laudes meas legerent?" ("Is it on that account that your Cereales and Anabasii circulated through many provinces, so that they might read my praises?") Middle Ages 
In the Middle Ages, royal courts maintained their own messengers who were paid little more than common labourers. Types
In cities, there are often bicycle couriers or motorcycle couriers but for consignments requiring delivery over greater distance networks, this may often include trucks, railroads and aircraft. Many companies which operate under a just-in-time or "JIT" inventory method often use on-board couriers (OBCs). On-board couriers are individuals who can travel at a moment's notice anywhere in the world, usually via commercial airlines. While this type of service is the second costliest—general aviation charters are far more expensive—companies analyze the cost of service to engage an on-board courier versus the "cost" the company will realize should the product not arrive by a specified time (an assembly line stopping, untimely court filing, lost sales from product or components missing a delivery deadline, loss of life from a delayed organ transplant).

Australia 
The courier business in Australia is a very competitive industry and is mainly concentrated in the high population areas in and around the capital cities. With such a vast mass of land to cover the courier companies tend to transport either by air or by the main transport routes and national highways. The only large company that provides a country-wide service is Australia Post.Australian Post operates quite differently to government departments, as it is government-owned enterprise focused on service delivery in a competitive market. It operates in a fully competitive market against other delivery services such as Fastway, UPS, and Transdirect. China 
International courier services in China include TNT, EMS International, DHL, FedEx and UPS. These companies provide nominal worldwide service for both inbound and outbound shipments, connecting China to countries such as the US, Australia, United Kingdom, and New Zealand. Of the international courier services, the Dutch company TNT is considered to have the most capable local fluency and efficacy for third- and fourth- tiered cities. EMS International is a unit of China Post, and as such is not available for shipments originating outside China. Domestic courier services include SF Express, YTO Express (圆通), E-EMS (E邮宝) and many other operators of sometimes microscopic scales. E-EMS, is the special product of a co-operative arrangement between China Post and Alipay, which is the online payment unit of Alibaba Group.

All couriers use the PIN code or postal index number introduced by India Post to locate delivery address. Additionally, the contact number of the recipient and sender are voluntarily added on the courier for ease of locating the address. Bangladesh 
The history of courier services in Bangladesh dates back to the late 1970s when private companies started offering delivery and parcel services. These companies played a crucial role in facilitating the movement of documents and goods within the country. Over the years, the courier industry in Bangladesh has grown significantly, adapting to changes in technology and expanding its services to include international shipments. Today, various local and international courier companies operate in Bangladesh, contributing to the country's logistics and trade networks. International courier services in Bangladesh include DHL, FedEx, United Express, Royale International Bangladesh, DSL Worldwide Courier Service, Aramex, Pos Laju, J&T Express, and Amazon.com. Apart from these, several local couriers also operate across Bangladesh Such as Sundarban Courier Service, Pathao Courier, e-dak Courier, RedX SA Paribahan, Sheba Delivery, Janani Express Parcel Service, Delivery Tiger, eCourier, Karatoa Courier Service, Sonar Courier . Almost all of these couriers can be tracked online. Malaysia

There are several international courier companies in Singapore including TNT, DHL and FedEx. Despite being a small country, the demand for courier services is high. Many local courier companies have sprung up to meet this demand. Most courier companies in Singapore focus on local deliveries instead of international freight. United Kingdom 
The genus of the UK same-day courier market stems from the London Taxi companies but soon expanded into dedicated motorcycle despatch riders with the taxi companies setting up separate arms to their companies to cover the courier work. During the late 1970s small provincial and regional companies were popping up throughout the country. Today, there are many large companies offering next-day courier services, including Speedy Freight, DX Group, UKMail and UK divisions of worldwide couriers such as FedEx, DHL, Hermes Group, Global Express Courier, UPS and TNT City Sprint. There are many 'specialist' couriers usually for the transportation of items such as freight/pallets, sensitive documents and liquids. The 'Man & Van'/Freelance courier business model, is highly popular in the United Kingdom, with thousands upon thousands of independent couriers and localised companies, offering next-day and same day services. This is likely to be so popular because of the low business requirements (a vehicle) and the lucrative number of items sent within the UK every day. In fact, from 1988 to 2016, UK couriers were considered universally self employed, though the number of salaried couriers employed by firms has grown substantially since then. However, since the dawn of the electronic age the way in which businesses use couriers has changed dramatically. Prior to email and the ability to create PDFs, documents represented a significant proportion of the business. However, over the past five years, documentation revenues have decreased by 50 percent. Customers are also demanding more from their courier partners. Therefore, more organisations prefer to use the services of larger organisations who are able to provide more flexibility and levels of service, which has led to another level of courier company, regional couriers. This is usually a local company which has expanded to more than one office to cover an area. Some UK couriers offer next-day services to other European countries. FedEx offers next-day air delivery to many EU countries. Cheaper 'by-road' options are also available, varying from two days' delivery time (such as France), to up to a week (former USSR countries). Large couriers often require an account to be held (and this can include daily scheduled collections). Senders are therefore primarily in the commercial/industrial sector (and not the general public); some couriers such as DHL do however allow public sending (at higher cost than regular senders). In recent years, the increased popularity of Black Friday in the UK has placed some firms under operational stress. The process of booking a courier has changed, it is no longer a lengthy task of making numerous calls to different courier companies to request a quote. Booking a courier is predominantly carried out online. The courier industry has been quick to adapt to our ever-changing digital landscape, meeting the needs of mobile and desktop consumers as well as e-commerce and online retailers. Offering end users access to instant online payments, parcel tracking, delivery notifications, and the convenience of door to door collection and delivery to almost any destination in the world. United States

The courier industry has long held an important place in United States commerce and has been involved in pivotal moments in the nation's history such as westward migration and the gold rush. Wells Fargo was founded in 1852 and rapidly became the preeminent package delivery company. The company specialised in shipping gold, packages and newspapers throughout the West, making a Wells Fargo office in every camp and settlement a necessity for commerce and connections to home. Shortly afterward, the Pony Express was established to move packages more quickly than the traditional stagecoach. It illustrated the demand for timely deliveries across the nation, a concept that continued to evolve with the railroads, automobiles and interstate highways and which has emerged into today's courier industry. The courier industry in United States is a $59 billion industry, with 90% of the business shared by DHL, FedEx, UPS and USA Couriers. On the other hand, regional and/or local courier and delivery services were highly diversified and tended to be smaller operations; the top 50 firms accounted for just a third of the sector's revenues. USPS is mail or packages delivered by the government and are the only ones who can legally ship to mailboxes. In a 2019 quarterly earnings call, the CEO of FedEx named Amazon as a direct competitor, cementing the e-commerce company's growth into the field of logistics. See also
