What is a UN/LOCODE?
The United Nations Code for Trade and Transport Locations is a 5-character code
for a place: 2 letters for the country (ISO 3166) plus 3 for the location.
USSEA is Seattle, GBLON is London and
DECGN is Köln (Cologne).
The codes are maintained by UNECE, published twice a year, and used in shipping, customs, airlines and logistics.
Why use it for IT naming?
Naming servers and network gear after a site's LOCODE gives every device a short, unique, internationally recognised location prefix:
USSEA-SQL001 USSEA-SW001 DECGN-NF001
It works across countries and stays clear of the 15-character Windows computer-name limit. Build your naming convention →
Common questions
Can I search with accents or other alphabets?
Yes. Köln, Koln and Koeln all find Köln; Zürich and Zuerich both work; you can type Москва or 北京, and common English names like Cologne, Munich or Vienna find the local entry.
Can I search by airport code?
Yes. Type an IATA airport code like SEA or CGN, or the last 3 letters of a LOCODE.
How current is the data?
It's the latest UNECE UN/LOCODE release, last updated 16 October 2026. The site checks for new and changed codes every week; see what's new.
What do the functions mean?
Each location lists what transport it handles: seaport, rail, road, airport, postal centre, multimodal facility, fixed installation (like a pipeline), or inland water port.
