Quoting from a previous message...
Hi all,
As far as I know these recommendations are NOT specifically for packet radio
but mainly used for APRS applications/stations. With CB packet radio it's
even hard to comply. For example, we don't use balloons, aircrafts of even
spacecrafts.
For packet radio there isn't really a recommendation as far as I can tell.
Some groups/clubs have made their own recommendations which some others used
too, but there isn't such thing as a world-wide, or even European
recommendation or standard for SSID usage on CB packet radio.

> APRS SSID Recommendations 6 Feb 2012
> ---------------------------------------------------------------------
>
> Updated 6 Feb 2012 to clarify the title of this document to be
> SSID RECOMMENDATIONS not to imply any kind of
> decoding "standard". That original NMEA
> decodign standard is covered in the original spec
> Updated 9 June 2010 for more flexibility using 1,2,3,4 and 15
> Revised 2 June 2004 to add -10, -11, 12 and -15
>
> SSID's have seen two different uses in APRS. Initially as an ICON
> indicator back in the early 1990's. But that is obsolete for over
> a decade. Now SSID's are used as an informal way of indicating one
> of several different typical APRS applications.
>
> Since many small displays for the handheld and mobile operator show

> to have some idea of what type of station or activity might be
> involved simply from the callsign SSID without having to push
> buttons, search lists, or look at maps to find out more about them.
>
> SSID RECOMMENDATIONS: It is very convenient to other mobile
> operators or others looking at callsigns flashing by, to be able to
> recognize some common applications at a glance. Here are the
> recommendations for the 16 possible SSID's (the limit of 16 comes
> from the 4 bits available in the AX.25 protocol. Note, The SSID of
> zero is dropped by most display applications. So a callsign with no
> SSID has an SSID of 0.
>
> -0 Your primary station usually fixed and message capable
> -1 generic additional station, digi, mobile, wx, etc
> -2 generic additional station, digi, mobile, wx, etc
> -3 generic additional station, digi, mobile, wx, etc
> -4 generic additional station, digi, mobile, wx, etc
> -5 Other networks (Dstar, Iphones, Androids, Blackberry's etc)
> -6 Special activity, Satellite ops, camping or 6 meters, etc
> -7 walkie talkies, HT's or other human portable
> -8 boats, sailboats, RV's or second main mobile
> -9 Primary Mobile (usually message capable)
> -10 internet, Igates, echolink, winlink, AVRS, APRN, etc
> -11 balloons, aircraft, spacecraft, etc
> -12 APRStt, DTMF, RFID, devices, one-way trackers*, etc
> -13 Weather stations
> -14 Truckers or generally full time drivers
> -15 generic additional station, digi, mobile, wx, etc
>
> * One-way trackers should best use the -12 one-way SSID indicator
> because the -9's usually mean a ham in full APRS communication
> both message and voice. The -9's can be contacted by APRS message
> or by Voice on his frequency included in his beacon, or on Voice
> Alert if he is in simplex range. The -12's are just moving Icons
> on the map and since they have no 2 way communication for ham radio
> they are not generally of routine interest to other operators.
>
> OBJECTS or INTERNET: In addition, Objects or internet generated
> stations can have any SSID, not just the original 16, since
> Objects are not constrained by the AX.25 header and can have a
> 9 byte name. Here are some common OBJECT/Internet SSID's:
>
> -63 for PSK63 HF stations
> -tt for APRS TouchTone users (DTMF)
> -ID for RFID
> -A through -Z for Dstar
>
> SSID BACKGROUND: Originally, in 1992, we had to use the SSID as
> a way of indicating the type of station that transmitted a raw
> NMEA-0183 GPS sting. But in the mid 1990's we began indicating
> any of the nearly 200 APRS symbols by the setting of the AX.25
> TOCALL of "GPSxyz". The "xyz" characters define the symbol from
> the standard APRS symbol table www.aprs.org/symbols.html.
>
> The GPSxyz concept worked so well, the original SSID associations
> are no longer a required part of the spec. But the conventions
> that evolved from those early SSID's are still encouraged as
> noted above, for easy recognition of station type or activity by
> when only the callsign is seen.
>
> The -1, -2, -3, -4 and -15 are kept generic so that anyone with
> as many as 6 digipeaters, or 6 trackers or 6 weather stations or
> 6 vehicles can still have unique SSID's for each of his stations.
> Beyond 6, people will just have to use any SSID that suits their
> fancy. In some areas there might be 15 digipeaters all under
> one guy's call!
>
> SSID USAGE: The SSID's also might give a hint as to how someone
> is getting into APRS whether via satellite, a one-way tracker, a
> mobile, an HT or even via DTMF or an RFID device or whether he is
> doing something special.
>
> For example, if you are doing something special, change your
> SSID to -6 to alert others to your excitement, or to make the
> track-history begin and end on site, and not be tied to all
> your other -9 travels. Or use -6 SSID for a packet sent
> via the ISS or APRS satellite or for a 6 meter test so the
> successful packet is preserved and not overwritten by the same
> radio the next time you use it not via the ISS on the 144.39
> national channel. By using separate SSID's the WEB data bases
> will keep statistics and data separate from when you are working
> normally on other bands with other SSID's.
>
> So stick to the suggestions above for the obvious applications
> where you can. Of course these are not rigid. If you have
> more than 6 digipeaters, use any SSID you want. These are only
> guidelines to hint at a station's possible application when all
> you can see easily is the callsign on a screen or in a list....
