EU5 Country Tags and Location IDs

EU5 runs two separate identifier systems, and console commands care which one you hand them. A country tag is a three-letter code that names a nation, like CAS for Castile or HUN for Hungary. A location ID is a plain number that names one tile on the map, a province, in old EU4 language. A command expecting a tag will error or silently no-op on a location ID, and vice versa, which is the single most common reason a console command "doesn't work."

How to find either one, live, in your own game

Don't try to memorize a static list. EU5 ships with well over a thousand playable tags and tens of thousands of locations, and both shift slightly between patches as new formables and map changes land. The reliable method:

1. Turn on debug mode (debug_mode in the console, or launch with the debug flag).
2. Hover the thing you want the ID for: a country on the diplomacy screen, a tile on the map. The tooltip prints the tag or location ID directly.
3. Type helplog in the console. The game writes a complete, current command and identifier reference to a text file inside your Documents/Europa Universalis V folder. This is the authoritative list for your exact build and DLC/mod combination. A wiki table is a snapshot from whenever someone last edited it; helplog is live.

That third method is the one worth remembering: it's the only source that's guaranteed to match your actual patch version, including any tags added by mods you have running.

Location IDs: no static table, and here's why

Location IDs don't get a reference table on this page at all, on purpose. Unlike tags, which are stable strings tied to a nation's identity and rarely renumbered, location IDs are dense sequential integers covering every land tile and sea zone on the map, and EU5's map has already shifted province boundaries between patches during 1.3.x balance passes. A hand-typed table of "location 7273 = Sevilla" would be wrong the moment a map-detail patch lands. The debug-hover method above takes ten seconds and is always correct for whatever build you're running.

Common command pairings

If a command errors out immediately, the first thing to check is whether you handed it a tag where it wanted a location ID. That mismatch, not a typo, is behind most "this command doesn't work" reports.
