Check underneath the bottom bracket first on a Liv, between the pedals. If it is not visible there, check the seat tube, head tube, down tube, rear dropout and non-drive-side seat stay. Liv is Giant’s women-focused sister brand, but do not assume every Liv model uses the same exact location, and there is no single Liv serial prefix to rely on. Use the full code on the frame rather than a guessed format.
That number matters. It helps you register the bike, check if it has been reported stolen, prove ownership, value it and sell it with more buyer confidence. Here is where to find it, how to read it, and how to check it before you buy.

The frame number on a Liv bike is most likely to be underneath the bottom bracket. If it is not there, check the seat tube, head tube, down tube, rear dropout and non-drive-side seat stay. There is no Liv-specific prefix to count on, so use the full number shown on the frame.
Start under the bottom bracket.
This is the most common place to find a Liv frame number. It is the part of the frame between the pedals, on the underside.
- Put the bike somewhere safe and well lit.
- Turn it upside down carefully, or place it in a workstand.
- Look underneath the frame where the cranks meet the bike.
- Wipe away mud, grease or road dirt.
- Use a phone torch if the number is hard to read.
- Take a clear photo before typing the number into a checker.
Make sure you copy the full number. A single missing or misread character can give the wrong result.
Can’t find it underneath the bike?
If the number is not under the bottom bracket, check these places next:
- Near the rear dropouts, where the back wheel fits into the frame.
- Around the seat tube.
- On the underside of the down tube.
- Near the head tube at the front of the bike.
- On the original sales receipt.
- In your Liv registration email or paperwork.
- With the Liv dealer that sold the bike.
On older bikes, repainted frames and heavily used bikes, the number can be harder to read. If it has been scratched off, covered, filed down or looks tampered with, treat that as a serious warning sign.
What does a Liv frame number look like?
A Liv frame number should be a unique mix of letters and numbers. It may be stamped into the frame, etched into carbon or shown on a factory label. If the bike is carbon, look carefully. The number may be lighter than on an aluminium frame and can be easy to miss if the frame is dirty or protected by tape.
Do not use the model name, tyre size, barcode on a shop label, or any number printed on a component. The frame number belongs to the bike frame itself. For example, these are not usually the frame number:
- Liv Avail
- Liv Langma
- Liv Devote
- Liv Thrive
- Liv Rove
- Liv Tempt
- Liv Intrigue
- Liv Embolden
- Liv Amiti
- Liv Vall E+
- Liv Flourish
- Advanced
- Pro
- 700c
- 27.5 inch
- 29 inch
- SyncDrive motor number
- EnergyPak battery number
- Shimano or SRAM component code
- Wheel serial number
The number you want is the unique frame code that belongs to the frame itself.
Liv e-bikes carry separate identifiers
Liv e-bikes can have separate motor and battery identifiers. Those are useful to record, but they are not a replacement for the bike frame number when checking theft history or proving ownership.
The detail that protects you.
A frame number is one of the most useful details on a used bike. It connects a Liv to its owner, its registration record and any stolen-bike reports.
You may need it to:
- Check if a Liv bike has been reported stolen.
- Register your bike.
- Sell your bike with confidence.
- Get an accurate bike valuation.
- Make an insurance claim.
- Report a stolen bike to the police.
- Prove the bike is yours.
If you own a Liv, take a photo of the frame number and keep it with your receipt. If the bike is ever stolen, that detail can make a real difference.
Buying a used Liv? Check the frame number first.
A clean-looking bike is not always a safe buy. Before you pay, ask the seller for a clear photo of the frame number and check it against stolen-bike records. You should also ask for:
- The original receipt or proof of purchase.
- The seller’s name matching the receipt where possible.
- Clear photos of the bike from both sides.
- A photo of the frame number.
- Any service history.
- Details of upgrades or replacement parts.
Red flag. Be careful if the seller refuses to show the frame number, says they cannot find it, gives only a partial code, or pressures you to pay quickly. A genuine seller should understand why you are checking.

What to do if your Liv has been stolen.
Report it as soon as possible. You will usually need the frame number, photos, make, model, colour, size, location and any unique marks or upgrades.
- Report the theft to the police.
- Get a crime reference number.
- Add the bike to stolen-bike databases.
- Update any existing bike registration record.
- Contact your insurer if you have cover.
- Watch used bike listings for matching bikes.
- Keep photos, receipts and messages in one place.
Include anything distinctive, such as upgraded wheels, unusual tyres, scratches, stickers, lights, mudguards, racks or replacement parts. The more detail you provide, the easier it is to identify the bike if it appears for sale.
Liv frame number FAQs
Is a Liv frame number the same as a serial number?
Yes. Most people use frame number and serial number to mean the same thing. It is the unique identifying code attached to the bike frame.
Do all Liv bikes have a frame number?
Most Liv bikes have a frame number or serial number. Check the locations described above first; on older frames the marking can be shallow or worn, so clean the area and check in good light before concluding it is missing.
Where is the frame number on a Liv Avail?
Check underneath the bottom bracket first. On carbon versions, look for an etched number or label.
Where is the frame number on a Liv Langma?
Start underneath the bottom bracket between the pedals, then check the seat tube and rear dropout.
Where is the frame number on a Liv Devote?
Check underneath the bottom bracket first. Clean the area, as gravel use can hide the code.
Where is the frame number on a Liv Tempt?
Start under the bottom bracket. If mud hides the number, clean the frame and check the rear dropout.
Where is the frame number on a Liv Vall E+?
Check the frame number separately from the motor and battery numbers. Start around the bottom bracket and motor-area frame sections.
What if the Liv frame number has been removed?
Do not buy the bike. A removed or damaged frame number is a major red flag. It may make the bike harder to register, insure, resell or prove as yours.
Can I check if a Liv bike is stolen by the frame number?
Yes. Use the frame number to run a stolen-bike check before buying. You should also ask the seller for proof of ownership and check that the details match the bike.

Bottom line
The quickest place to find a Liv frame number is underneath the bike, near the pedals. Look for a stamped code or barcode sticker, copy the full number, then check it before you buy, sell or register the bike. A used Liv can be a brilliant buy, but the frame number is the detail that protects you.
