Besides awk, another way is to use csplit (assuming max 100000 vcards):

$ csplit -n 5 -z vcard.txt '/BEGIN:VCARD/' '{*}'

This is not really useful by itself since you don't have much control over
file names.
However, you can use a subsequent loop to rename all the files.

All the commands are tested with bash and GNU tools, so they may use
nonstandard features. I try to specify when something is nonstandard (if I
know that), but I may still miss something. Corrections are welcome.
