What is Prefix?

A prefix is a letter code that appears at the beginning of a sequence of digits or numbers, often used in logistics and transportation to identify a shipment’s country of origin or destination. The prefix is typically a two or three-letter code representing a specific country, region, or instance.

In logistics, prefixes identify shipments’ origin and destination and track packages as they move through the supply chain. For example, the prefix “US” is used to identify shipments originating in the United States, while “CN” is used to identify shipments from China. Each country has its unique prefix, which can be used to identify a shipment’s country of origin or destination easily. Prefixes are often combined with other letter codes and numbers to create a unique identifier for each shipment.
