A telecommunications company is a kind of electronic communications service provider, more precisely a telecommunications service provider (TSP), that provides telecommunications services such as telephony and data communications access. Many traditional solely telephone companies now function as internet service providers (ISPs), and the distinction between a telephone company and ISP has tended to disappear completely over time, as the current trend for supplier convergence in the industry develops. Additionally, with advances in technology development, other traditional separate industries such as cable television, Voice-over IP (VoIP), and satellite providers offer similar competing features as the telephone companies to both residential and businesses leading to further evolution of corporate identity have taken shape.

Due to the nature of capital expenditure involved in the past, most telecommunications companies were government-owned agencies or privately owned monopolies operated in most countries under close state regulation. But today there are many private players in most regions of the world, and even most of the government-owned companies have been opened up to competition in-line with World Trade Organization (WTO) policy agenda. Historically, these government agencies were often referred to, primarily in Europe, as PTTs (postal, telegraph and telephone services). Telecommunications companies are common carriers, and in the United States are also known as local exchange carriers. With the advent of mobile telephony, telecommunications companies now include wireless carriers, or mobile network operators and even satellite providers (Iridium).

Transit police (also known as transport police, railway police, railroad police and several other terms) are specialized police agencies employed either by a common carrier, such as a transit district, railway, railroad, bus line, or another mass transit provider or municipality, county, district, or state.

Transit law enforcement services may also be provided by a specialized unit within a larger local law enforcement agency. Their mandate is generally to prevent and investigate all crime committed against the carrier or its passengers and crime incidentally committed on or around the carrier's property.

Commuter rail services in the United States, Canada, Cuba, Mexico, Panama, and Costa Rica provide common carrier passenger transportation along railway tracks, with scheduled service on fixed routes on a non-reservation basis, primarily for short-distance (local) travel between a central business district and adjacent suburbs and regional travel between cities of a conurbation. It does not include rapid transit or light rail service.

A bill of lading (/ˈleɪdɪŋ/) (sometimes abbreviated as B/L or BOL) is a document issued by a carrier (or their agent) to acknowledge receipt of cargo for shipment. Although the term is historically related only to carriage by sea, a bill of lading may today be used for any type of carriage of goods.

Bills of lading are one of three crucial documents used in international trade to ensure that exporters receive payment and importers receive the merchandise. The other two documents are a policy of insurance and an invoice. Whereas a bill of lading is negotiable, both a policy and an invoice are assignable.

A freight forwarder or forwarding agent is a person or a company who co-ordinates and organizes the movement of shipments on behalf of a shipper (party that arranges an item for shipment) by liaising with carriers (party that transports goods). The carriers may use a variety of shipping modes, including ships, airplanes, trucks, and railroads, and often use multiple modes for a single shipment. A freight forwarder does not move the goods but acts as an agent in the logistics network and will carry out freight consolidation, rate negotiations, shipment tracking, customs and other documentation, among other tasks. FIATA describes a freight forwarder as the "architect of transport".

International freight forwarders typically handle cross-border logistics and have additional expertise in preparing and processing customs documentation and performing activities pertaining to the regulations of different countries. Freight forwarders typically have information with respect to commercial invoice, shipper's export declaration, bill of lading and other documents required by the carrier or country of export, import, and/or transshipment.
