Bianchi frame code

[citybabe]

Does anybody know where I am likely to find the frame number ?

I have a sticker on the underside of the bike with numbers written on and also there are numbers kind of etched into the underside of the bike too

It's usually impressed underneath the bottom bracket.

Thanks. I did think that the impressed numbers would be the frame number

I take it you've found it CB on my carbon framed Bianchi its on the inside of the plate where the seat stays and chain stays meet.
