Basically, the answer to the title question is "You can't." There's no global database and each manufacturer just uses whatever scheme they want. Unless you've already narrowed it down to a couple of candidate manufacturers, the serial number won't help you.
The logo on the downtube shows some similarity to the logo on this bike: https://www.ccrracing.de/road-rahmen/13-ccr-attack-carbon-rahmen.html
I can’t find a similar looking model on that site but you could contact them at least to ask about the serial number. It seems like the best place to ask, in the first instance.
It looks to me like it’s a metal ...
Generally, it's impossible to tell anything from bicycle serial numbers. Manufacturers do not provide a way to look up serial numbers and get a model name or a description of the original configuration.
Some women's specific models are sometimes marks as such. When women's specific models started to appear they often had paint schemes based on pinks and ...
You will need to contact Leader Fox to answer this question.
The Leader Fox website does not have any information on which of those numbers is the bicycle serial number.
Here is a link to the manuals for their bikes.
Their manuals do contain information on the serial number for the motors on their e-bike which is not the same thing as the serial number for ...
The short answer is that it's a lot of work and there is no one way of identifying every bike. Sometimes a bike impossible to identify.
Documenting all the things to look for that might help ID a bike would take a large book. Here is some high level information to get you started.
As a rule of thumb
The less information you have to start with the less ...
Your bicycle is a

Your next options are to complete that registration process, and to look through https://www.google.com/search?q=giant+boulder+&tbm=isch and ...
Here is a 1986 Redline RL-20a with a frame that matches closely. Both the 1986 and 1987 (there are no RL-20a bikes in BMX Museum after 1987)
1986 Redline catalogue page 16-17 shows that the 20a frame is the one with the brake strap anchor.
It has the correct
- off center bottom bracket down tube location
- brake strap anchor
- rear drop out ...
You can find some useful info over here Decoder Info
Looking at your serial number tells me it's October 1987.
More info can be found over the BMX museum, the link can be found from the link posted above or here BMX Museum Haro
I heard back from Cannondale support. The sticker is the only way to know the serial number on their newer bikes:
No, the serial number is not stamped on the frame. It is underneath the bottom bracket on a sticker with a bar code, 2 letters + 5 numbers.
I would suggest that when you register your bike, put both numbers/strings into the system.
If you only put one, then some day when its been recovered after a theft, the operator might put the other number in, and not score a match.
Whichever is the correct serial number doesn't really matter in this specific case.
If some other bike duplicates one block of ...
Looking at the frame, I initially doubted whether this is a genuine bike - there were plenty of people making stickers and slapping them on average bikes. The paint job isn't particularly fancy, and the lugs on the frame are not scalloped like a high end bike. The fork is Columbus, but there is no Columbus sticker on the frame.
But, "Eddie Mercx" ...
Phone the bianchi distributor and ask them. The UK one is very helpful.

I'll add that it's normally quite easy to tell the model year by the livery. With Bianchi you can also tell the original specification by the livery. Compare yours to the back catalogue.
Of course - the trouble is that there is no single good source of information about the EMC frames, verification will be difficult....
I've been writing about EMC bikes on various forums (bikeforums, paceline, rennrad-news) for a few years now as CyclesMakaron, Emerxil etc - that's how I got in touch with millfieldvelo (you'll find a link to me on his site)
The K logo is definitely not Kona, my daily rider is a Kona Fire Mountain. KonIA (Konia) maybe? Lower end MTB manufacturer.
BTW my saddle and seat pole definitely NOT Kona. I broke and replaced them myself!
