A note to people looking for identifier tables: Weather Graphics maintains the Master Location Identifiers Database (MLID) here:
http://www.weathergraphics.com/identifiers
There is a continuously updated Standard Version that is provided to the community free of charge, and a Professional Version at additional cost which includes historical rows and start/stop dates. The Professional Version charge recovers time and effort incurred putting the listings together, and covers our costs for historical documents, AIP access, and data access charges.
I also need to caution people about using unofficial identifier sources found on the Internet. There are a couple of crowdsourced identifier websites which have gradually turned into massive sources of misleading and unofficial identifiers. This data has gotten into a lot of places like Wikipedia, Wikimapia, and some university station tables. The only official source of official ICAO identifiers is the ICAO (Doc 7910) and official Aeronautical Information Publications. Where there is an office that maintains national identifiers (such as the FAA) or which announces changes on NOAAPORT, those are considered a valid supplement to the AIP. When using new sources we use various tests to check for known misleading data in circulation to make sure it doesn't corrupt the MLID, and test against these sources.
Our Station Identifier forum moderator (tstm) is welcome to tag onto this thread to add additional useful reference information and sources of data. Tstm's work is independent from us and we support his work in disseminating useful information to all hobbyists and professionals.

Board update
Effective April 12, 2021, we had to delete about 8000 frivolous spammer accounts going back over a year. There was no way for us to locate all legitimate user applications, so some may have been deleted. If you are an actual user who created an account since March 2020 but did not get approved, please register again. You can also contact us via the Contact link on the main Weather Graphics webpage to get assistance. When you contact us, it is essential you provide brief but detailed info on your meteorological background or inform us of any previous order you've made, this way we can tell you are a legit user, otherwise we will assume it is a spammer trying to bypass the application checks. Thanks. -Tim
