# What airport is SLC?

**SLC is: Salt Lake City International Airport**

Salt Lake City, United States

## Why the code is SLC

Salt Lake City, initials.

The airport authority or a contemporaneous record states this directly.

## The airport

- **IATA code:** SLC
- **ICAO code:** KSLC
- **Airport:** Salt Lake City International Airport
- **City:** Salt Lake City, United States
- **Code origin:** Documented

At 1,288 m it is one of the higher major US airports, which lengthens takeoff runs, and it sits directly beneath the approach to the Wasatch Range. Delta rebuilt the whole thing between 2014 and 2024 while continuing to operate it, which is rarer than it sounds.

## The other code, KSLC

Every airport has two codes. The three-letter IATA code, SLC, is the one on your boarding pass and your luggage tag, and it is assigned for commercial use. The four-letter ICAO code, KSLC, is the one pilots and controllers use, and it is assigned geographically: the first letter or two identify the region, so every airport in the same part of the world shares a prefix. That is why KSLC looks nothing like SLC.
