Reading the code CUMTZ
UN/LOCODE is the United Nations Code for Trade and Transport Locations, a standardized system that assigns short codes to seaports, airports and other transport points worldwide. Each code has five letters: the first two identify the country and the last three the specific place.
For the Port of Matanzas the code is CUMTZ. Here 'CU' is the country code for Cuba, and 'MTZ' identifies Matanzas within Cuba. Reading the code this way makes it easy to confirm you are looking at the right country and location before relying on any document.
Why a standard code matters
Place names can be ambiguous. They are spelled differently across languages, abbreviated inconsistently, and sometimes shared by more than one town. A neutral, agreed code removes that ambiguity, which is why UN/LOCODE is used in logistics, customs data and vessel schedules.
When you see CUMTZ on a bill of lading, a routing, or a port-call record, it unambiguously refers to Matanzas in Cuba. That precision is valuable for anyone tracing cargo movements or researching the port from public data.
Using the code in practice
If you are searching trade or vessel databases, entering CUMTZ rather than the plain name 'Matanzas' will usually give cleaner results, because it filters to the coded location. It also helps distinguish the Cuban port from similarly named places elsewhere.
The code is maintained within the official UN/LOCODE list published by UNECE, which remains the authoritative reference. Beyond the code itself, remember what it points to: a deep-bay oil and bulk port on Cuba's north coast. The identifier and the physical port together let researchers, shippers and travelers speak about Matanzas without confusion.
Codes, names and common confusions
It is worth remembering that a UN/LOCODE is a location code, not a facility license or a berth number. CUMTZ marks the place — Matanzas, Cuba — while individual terminals, berths and operators within the port carry their own designations in operational systems.
Travelers sometimes confuse the code-worthy port city with the province of the same name, or with unrelated towns called Matanzas elsewhere in the Spanish-speaking world. The five-letter code cuts through that: the 'CU' prefix fixes the country beyond doubt. When you need to be certain you are dealing with the Cuban north-coast port and not somewhere else, CUMTZ is the reliable shorthand, and the official UNECE list is where its status can always be checked.
