List of observatory codes

This is a list of observatory codes, or IAU codes, with their corresponding astronomical observatories. The Minor Planet Center (MPC) – a service of the International Astronomical Union – assigns for each registered observatory a 3-digit code in the range 000 to Z99.

The code serves as a unique identifier for observations taken of hundreds of thousands of minor planets and thousands of comets orbiting in the Solar System. More than 197 millions such astrometric records exist. This list is based on MPC's periodically published and revised "List Of Observatory Codes". Over time, the number of astronomical observatories worldwide has been growing constantly. As of October 2018, this list contains 2095 observatory codes published in MPC's official list.

The registry is limited to observatories which perform minor planet observations. While this includes most optical telescopes of note and a great many amateur facilities, it does not include the U.S. National Solar Observatory or many notable radio observatories (such as the Llano de Chajnantor Observatory, MeerKAT, or the South Pole Telescope).

The following list contains an observatory's name and code as used by the MPC, its location and, optionally, a link to the corresponding article on Wikipedia and an external link to the observatory webpage.
