Before you submit

The 3-letter code and the status are assigned by the UNECE secretariat. Any code you enter is a suggestion only — status is intentionally not collected here. Review the summary, then create your request.

Step 1 — Locate the placeOpenStreetMap

This step only pins the place on the map: picking a match sets the coordinates and fills in the country and subdivision. Not found? Search for a nearby town or a broader name, or simply click or drag on the map to place the pin yourself. You name the entry in step 2 — the name you submit does not have to match the search.

Search for the placeA place name, port, or nearby town — used to find the point, not as the entry name.

CoordinatesDDMM[N/S] DDDMM[E/W] · Rec 16 col 11. Required since 2020.

Coordinates (decimal) · optionalFiner-grained decimal degrees, kept alongside the Rec-16 value.

Step 2 — Name and administrative details

Refine what the directory should record. The name is yours to set — it does not have to match what the map returned.

Location nameInternational gazetteer name (Rec 16 col 4). Diacritics allowed.

Name without diacriticsRec 16 col 5 — ASCII form, derived automatically from the name.

Country / territory

Subdivision · optionalISO 3166-2 code after the hyphen (Rec 16 col 6).
