(Updated: November 14, 2024)
A SIGINT Activity Designator (or SIGAD) is a alphanumeric designator which identifies a facility that is used for collecting Signals Intelligence (SIGINT). These facilities have many different forms, ranging from satellite intercept stations, spy ships and satellites, to sites where internet cables are tapped.
SIGADs are used for intercept facilities operated by the signals intelligence agencies of the United States, the United Kingdom, Canada, Australia and New Zealand, as these five countries have a close relationship for collecting and sharing signals intelligence under the so-called UKUSA-agreement.
Since World War II several thousand SIGADs have been assigned. By 1955, the US had for example more than 2000 listening posts around the world.*
A screenshot of the NSA's BOUNDLESSINFORMANT tool showed that in March 2013 there were 504 active SIGADs, which means that in that month NSA collected data from 504 intercept facilities. This number probably includes many subsets and maybe a several dozen are really significant sources.

data are collected worldwide through 504 SIGADs
A typical SIGAD looks like USN-855
The first two letters indicate the country and can be US for the United States, UK for the United Kingdom, CA for Canada, AU for Australia and NZ for New Zealand.
Then comes one letter indicating what sort of staff runs the station, which can be M for Army, N for Navy, A for Air Force, J for Joint services (mainly military), F for Joint services (mainly civilian), D for Detachment or C for Civilian staff.
After a hyphen follows a unique number which identifies the particular facility.
An additional alphabetic character is added to denote a sub-designator for a subset of the primary collection unit, like a detachment. Lastly, a numeric character can be added to provide for a sub-sub-designator. When a particular SIGAD has one or more sub-designators these are indicated by an asterisk (*).
An example of a SIGAD with a sub-sub-designator is US-987LA
Below is a list of all known SIGADs from past and present and from all five UKUSA-countries. Sorting the unique numbers in groups of hundreds, revealed that they are apparently assigned according to this scheme:
1 - 89: US Army, Navy, Air Force
90 - 100: Canada
101 - 200: United Kingdom
201 - 300: United Kingdom
301 - 400: Australia and New Zealand
401 - 499: US Navy
500 - 599: US Air Force
600 - 699: US Army
700 - 799: US Joint services
800 - 899: Various US services
900 - 999: NSA
1000 - 1999: NSA
2000 - 2999: ?
3100 - 3199: NSA
3200 - 3299: NSA
3300 - 3399: NSA
3400 - 3499: NSA
Presently, only a few SIGADs from the 1000-range and none from the 2000-range are known. Maybe these are used for new intercept facilities of US military services and for SIGINT units deployed in the Afghanistan and Iraq wars, like the large number from the 600-range used for intercept sites during the Vietnam war.
When a facility was shut down, the agencies were free to reuse the SIGAD again. Since 2005, the NSA's master list of SIGADs (and PDDGs) was maintained in the GOLDPOINT 2 database.
Some SIGADs seem to be highly classified and may not be mentioned in documents accessible to all Five Eyes-partners.
Some documents leaked by Edward Snowden show that there are also communications collected by facilities under a designation starting with DS, but for reasons yet unknown these doesn't fit the regular SIGAD-scheme:
DS-200: "NSA's reporting of GCHQ's Special Source collection"
DS-200A: ?
DS-200B: MUSCULAR
DS-200X: ?
DS-202A: ?
DS-204A: ?
DS-300: INCENSER
DS-410: ?
DS-600: CSE reporting?
DS-800: ?
> See also: What are SIGADs starting with DS for?
A declassified NSA training program storyboard from 2011 says that domestic internet (PR/TT) and telephony (BR) metadata collected under FISA authority have SIGADs that begin with a specific character, which is stil classified. This could explain why some SIGADs are blacked out, even in some of the Snowden-documents.

Missing one USF-63 Rosman, NC. http://www.atomicexpress.net/2012/06/04/the-rosman-research-station-aka-nsa-field-station-f63/
Thank you, it's added to the list!
Thanks for this post. One possible correction: as I wrote here (http://luxexumbra.blogspot.ca/2013/10/introduction-to-sigads.html), "the suggestion that the AFP numbers associated with some U.S. military space programs are the SIGADs for those systems is, I believe, not correct. As Dwayne A. Day explains here (http://www.thespacereview.com/article/1750/1), AFP numbers were used for a wide variety of space programs, including SIGINT satellites, but also including communications satellites, meteorological satellites, R&D satellites, IR/early warning satellites, and photo reconnaissance satellites. Furthermore, unlike SIGADs, AFP numbers were used for public references to those various programs."
Thank you for the correction! I didn't know the article explaining the satellite designations, but it clearly makes sense, as the AFP-numbers also didn't fit the SIGAD-scheme. I will correct the article.
Impressive job ! Here are some you can add to your list :
USN-18: Dupont, SC (as of 1945)
USN-18: Panama (as of 1976)
USA-36: unknown (existed as of 1967)
USM-76: Panama (with a detachment on Beacon Hill)
(numbers found in Tom Johnson's American Cryptology during the Cold War, volumes )
USA-50: 6950th Security Group at Chicksands, UK
USD-1025: "GCHQ Cheltenham" ("USD" means probably the SUSLO - Senior US Liaison Officer)
From Duncan Campbell, "The Eavesdroppers", Timeout, 1976
http://www.duncancampbell.org/menu/journalism/timeout/Eavesdroppers.pdf
USM-818: related to CTF-76 ? see http://www.nsa.gov/public_info/_files/gulf_of_tonkin/sigint_reports/rel1_sigint_report_list_miguel.pdf
Many thanks for the additions, I will add them to the listing!
Again another one :
USM-2: ASA post at Two Rock Ranch in Petaluma, California (1942-1971).
(also from American Cryptology during the Cold War. I hope we'll get soon more declassified versions of volumes I and IV.)
Thanks again - this is clearly the correct facility, instead of the US embassy in Moscow, as supposed by another source.

Some more SIGAD descriptions:
"International Transit Switch Collection*: International Transit switches, FAIRVIEW (US-990), STORMBREW (US-983), ORANGEBLOSSOM (US-3251), and SILVERZEPHYR (US-3273), are Special Source Operations (SSO) programs authorized to collect cable transit traffic passing through U.S. gateways with both ends of the communication being foreign."
Source: https://www.aclu.org/sites/default/files/assets/sid_oversight_and_compliance.pdf
More on SILVERZEPHYR here:
http://oglobo.globo.com/infograficos/big-brother-am-latina/
I believe we can identify seven cable intercept sub-SIGADS for US-983: STORMBREW, which we know to be under Transit Authority (corporate partners for transit switch access with 27 opc/dpc pairs.
Another Snowden document identified seven sites associated with STORMBREW all code named after ski resorts: BRECKENRIDGE in Hillsboro,OR; COPPER MOUNTAIN in New York City; KILLINGTON in Lynn, MA; MAVERICK in Miami;
SUNVALLEY in Morro Bay, CA;
TAHOE at Point Arena, CA; and WHISTLER in San Antonio.
From various cable almanacs and carrier websites I believe BRECKENRIDGE is the Verizon TPE Hillsboro Cable Landing Station; COPPER MOUNTAIN is at the Verizon hub on Hudson St.; KILLINGTON is the Hibernia Networks cable landing in Lynn; MAVERICK is the Verizon-Terremark NAP of the Americas; SUNVALLEY is the major Pacific cable landings for AT&T, NTT & KDDI; TAHOE is the AT&T Manchester Cable station; and WHISTLER is likely the AT&T POP switch at 815 Avenue B.
Thank you - that's an interesting addition!
Found again a SIGAD in NSA's historical documents :
USF-61 in the history of the Suez crisis : https://www.nsa.gov/public_info/_files/cryptologic_histories/Suez_Crisis.pdf (p. 41)
There was a CIA listening station on Cyprus that was taken over by the NSA in 1956, and it was the only US station in the area at the time, so I suppose USF-61 is this Cyprus station.
And again some others as of 1969:
USA-30 : Wakkanai, Japan (according to Seymour Hersh's book "The Target is Destroyed", the USAF listening post at Wakkanai was turned to the Japanese in 1975. In 1982, a clandestine survey USAF listening post was created at Wakkanai along or inside the Japanese one, but probably with a new SIGAD).
USA-58 : Hakata
USN-39P : unknown
https://www.nsa.gov/public_info/_files/cryptologic_histories/EC-121.pdf

Thank you very much for the huge list! For now, I added them as a link, to include them in the listing in the future.
The NSA has published a new release of American Cryptology During the Cold War 1945-1989, Book I : https://www.nsa.gov/news-features/declassified-documents/cryptologic-histories/assets/files/cold_war_i.pdf
Some new SIGAD revealed :

Location for a UK SIGAD - UKM251M was the sub-station of UKM251 intercept site operating out of Teufelsberg, Berlin (3 Squadron, 13 Signal Regiment(Radio)). As an aside, all the Germany intercept site are, indeed, "former" sites.
Rereading my comment, I realize it is confusing... UKM251M was Teufelsberg, sub-station of UKM251 (Birgelen). Additionally, UKM251H closed in 1991, having opened in 1973. Before being handed over to the British, this site was USM-44L, 1970-73, unsure of the ASA unit. UKM251M closed in 1992, as did the Langeleben (note spelling) facility, and UKM251 ceased operations in 1994. I also notice that UKM151 is missing. This was 224 Signal Squadron, a training unit in Woodhouse Eaves, Leicesershire, England, 1959-1980. In 1980 it became Communications and Security Group (UK) (CSG(UK)) until 1990 - I don't know if it kept the same SIGID at that time.
Hi Anonymous; USM-44L: Groß Gusborn, Germany, site of 2nd former NSA and US Army ASA Border Site Command Torii tower (1965-June 1974), turned over to UK 13th Sig Rgt. My understanding is USM-44K: Schöningen / Wobeck, Germany, Det K, 319th ASA Bn, ASA Border Site Command (1965-19 Nov.1992),was also site of 1st NSA-ASA Torii tower(1969-1976)
I didn't notice USAF San Vito AS, Italy, SIGINT facility with Navy and Army. I believe it closed back in the 90's...
My records show:
USA-74B: San Vito Dei Normanni, Salento Peninsula, Brindisi, Apulia, Italy, San Vito Dei Normanni Air Station, 6917th USAFSS (closed Aug. 1, 1991)
Also:
USM-6??: San Vito dei Normanni, Salento Peninsula, Brindisi, Apulia, Italy, San Vito dei Normanni Air Station, 6917th Security Group, USAFSS (1960-06 Jan. 1993) [AN/FLR-9 1962-Oct. 1994]
USN-6??: San Vito dei Normanni, Salento Peninsula, Brindisi, Apulia, Italy, San Vito Dei Normanni AS, NSGA San Vito at San Vito dei Normanni Air Station (23 Sept. 1964-06 Jan. 1993)
US-967J: SCS Kuwait City [from SID Today, 05/30/2006]
US-969X169A: Temporary SCS site in Hyderabad, India established for Presidential visit to India, 27 February-06 March 2006

In his list LWS listed United States Army Signal Research Unit 11. FYI it wasn't a SIGINT site. It was ACOUSTINT. Not in Bangkok, it was at the Don Muang RTAFB. That was the control point for several sensors around the nearby countryside.
