“GeoPostcodes’ Population data shows population forecasts over the next years. We can use it as a proxy to justify longer-term changes and downgrade postal code areas in terms of economic viability.”

Kousha Mazloumi

Director of Data Science

“The concept of the city receives different names or belongs to different hierarchical levels depending on the country. Using GeoPostcodes’ data gave us access to city definitions aligned with our customers’ expectations, saving us computation time.”

Kousha Mazloumi

Director of Data Science

“The world is constantly changing. New localities and neighborhoods open up or become dispersed. It’s good to know that GeoPostcodes is keeping on top of those changes and providing us with updated information to work with.”

William Chao

Product Owner of Geographic Information Services

“The key aspect of working with GeoPostcodes has been their ability to provide customized data solutions. Their collaborative approach has made them an excellent partner in addressing our location data challenges.”

Kate Kilby

Senior Product Manager

“GeoPostcodes’ multi-level boundaries were perfectly aligned, enabling seamless integration with multiple secure cloud platforms. Our software can now provide more accurate visualizations for risk analysis and natural hazard monitoring.”

Dave Hamm

Project Manager

“Countries like Brazil or China are particularly strict with their customs validation. GeoPostcodes’ ZIP codes and Enhanced UNLOCODES database are aligned with national regulations, ensuring seamless transportation and compliance.”

Kavian Ranjbar

Frequently Asked Questions

How do I match a ZIP code to UN/LOCODE or IATA references in a UNLOCODE database?

You can match a ZIP code to UN/LOCODE or IATA references by linking postal geography with standardized transport-location codes. While GeoPostcodes does not distribute the original release files from the United Nations Economic Commission, our UNLOCODE-style dataset links postal data, transport locations, and coordinates using a unified geographic structure.

To support this type of cross-referencing, you can rely on:

Postal Codes for ZIP and locality structures
Cities Database for urban reference mapping
Port Terminals for maritime transport locations

Why are accurate coordinates important when working with a UNLOCODE database?

Accurate coordinates ensure that UN LOCODE entries correctly represent real-world trade, airport, and seaport locations. Precise geocoding prevents misalignment when validating routes, analyzing transportation networks, or linking postal data to international transport nodes.

What are typical uses of the GeoPostcodes UNLOCODE database?

A UNLOCODE-style database supports workflows such as:

Routing analysis across ports, airports, and inland terminals
Matching transport-location codes to postal or city datasets
Integrating unified location codes into multimodal logistics systems
Enriching internal databases with standardized transport references

Our global datasets are structured for enterprise mapping and interoperability. For transport-location coverage, see Port Terminals and Cities.

Can registered users submit online requests or work with CSV release formats?

While GeoPostcodes does not host the official UN online portal, our structured UNLOCODE-style database supports workflows where users need to submit updates, integrate transport references, or import CSV-friendly formats. We provide data in stable CSV structures optimized for ETL pipelines without duplicating the original external release packages.

All transport-location and postal datasets (including Postal Codes and Port Terminals) are available in CSV-compatible formats.

Are Python file prerequisites needed to process UN LOCODE-related data?

Many organizations use lightweight Python scripts to automate lookups, merge transport-location tables, or clean UN LOCODE–style fields. Although GeoPostcodes does not publish the original MDB or CSV packages from the UN, our datasets are optimized for parsing in Python, making it easy to integrate them into ETL workflows.

How does a code adopted by the UN compare to local referencing inside a UNLOCODE database?

A UN-adopted code identifies globally recognized transport and trade locations. While GeoPostcodes does not assign official UN LOCODE codes, our UNLOCODE-style dataset aligns local postal and geographic structures with UN-compatible fields. This ensures users can cross-reference local data with international transport identifiers without relying on external distribution channels.

You can explore cross-reference-ready datasets on our Cities and Port Terminals product pages.
