# Lid

Location Identifier (LID) data mapping facility identifiers to facility types, names, and responsible control agencies

**Source:** NASR table `LID` · version `e25086c3e952` · effective 2026-04-16

> The unique record key is the combination of LOC_ID, CITY, and FAC_TYPE. Replaces the legacy LID.txt Subscriber File. A numeric suffix (e.g., '(2)') may be appended to Special Use Resource FAC_TYPE values when more than one exists for a LOC_ID/City pair.

## Example query

```graphql
# Introspect the Lid type in GraphiQL at https://api.nav.sortie.co/graphql
# Example shape (pair with a compatible root query field):
{
  # ...rootQuery... {
    effDate
    countryCode
    locId
    regionCode
  # }
}
```

Run at https://api.nav.sortie.co/graphql (GraphiQL available in-browser).
