Is this the serial number?

Bike serial numbers aren't standardized across the industry (or even, often, within a company), but there are a few tips we've found that might help you if you see multiple numbers that could be serial numbers. 

• If it starts with EN (such as EN 14766) , it's most likely the bike's part number, and not the serial number. If you set your serial number to one of the numbers we suspect to be a part number, we'll flag it for you. 
• If you have a Specialized bike, there's a good chance that the serial number will start with WSBC. 
• If you have a Trek bike, there's a good chance that the serial number will start with WTU. 
• Did you get a receipt with your bike? Bike shops often print the serial number on the receipt.
