Which is my serial number??

I've searched on this interwebz-wide, including images, and somehow I can't find a single word about this. Every image and reference I found shows a photo of a single number.

I recently moved and need to register the bikes in the house (lost the original inventory and serial list along the way). So I go looking for serial numbers. Find them all on the bottom brackets - well them and at least one other number. All have at least two different character sequences on the BB, usually on opposite edges, and I have two Ti bikes that have three character sequences all machined one right below the next. There is no rhyme or reason that quickly indicates if one is a SKU, or a serial, or a build date or a who-knows-what.

How do I tell what my bikes actual serial numbers are? Just record everything and hope it makes sense to someone if they are ever stolen?

I'd go for the "record everything" approach. If you don't know, how will the doughnut-and-coffee cop know which one's the right number?

Take pictures and save them. Get close ups of those numbers and any unique marks whether existing damage or other. You can stamp your own notation somewhere on the bike if you know how and have the stamps.

If some document is asking for the SN, then just make a notation saying you can't determine it.

Serial numbers have been put just about every place imaginable on a bike frame. Some mfrs changed where they put it every so often and even depending on the model of bike.

A pic might help us. And for sure telling us what make and model the bike is might give us a clue what to tell you.

pick a number that looks like a serial number and put it on the form. It's not really that important, they won't check it if it's stolen anyway

bikes donít have standard serial# formats or locations like car VINs - every manufacturer does their own thing. Any number you find stamped into the frame might be the serial# or it may not. In your case it doesnít matter - you just need some number that will uniquely identify your bike. Record everything and sort it out if you ever need to. If it really matters, try contacting the manufacturer and asking them which of these number sequences is the Serial#

Thanks for the feedback. I'll just photo/record everything and leave it at that.
