**Quick answer:** The frame number on a Peugeot bike is usually stamped underneath the bottom bracket, between the pedals. On older steel frames also check the rear dropouts, where the back wheel sits, because that was a common stamping spot.

On a Peugeot, check underneath the bottom bracket first, then the rear dropouts. A large share of the Peugeot bikes still in use in the UK are older steel road and touring frames, and on frames of that era the serial was commonly stamped into the bottom bracket shell or into the flat faces of the rear dropouts.

## Start under the bottom bracket.

This is the most common place to find a Peugeot frame number. It is the part of the frame between the pedals, on the underside.

1. Put the bike somewhere safe and well lit.
2. Turn it upside down carefully, or place it in a workstand.
3. Look underneath the frame where the cranks meet the bike.
4. Wipe away mud, grease or road dirt.
5. Use a phone torch if the number is hard to read.
6. Take a clear photo before typing the number into a checker.

### If it is not under the bottom bracket

- 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 Peugeot registration email or paperwork.
- With the Peugeot dealer that sold the bike.

## What a Peugeot frame number looks like

A unique alphanumeric code stamped into the frame. Marking practice varied widely across the decades Peugeot built bikes, so record the whole code exactly rather than expecting a fixed pattern.

### Not the frame number

- Peugeot Carbolite 103
- Peugeot Premiere
- Tubing decals
- Frame size
- Component stampings on cranks or hubs
- Safety standard numbers

## On a vintage frame, expect wear

A stamped serial on a frame that is decades old may be worn shallow, painted over during a respray, or partly hidden by rust. Clean the area gently and use raking light. A respray that has filled the stamping is common on old bikes and is not by itself a sign of theft, but it does make the bike harder to identify and to prove as yours.

## Buying a used Peugeot

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.

## Bottom line

The quickest place to find a Peugeot 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 Peugeot can be a brilliant buy, but the frame number is the detail that protects you.

## Frequently asked questions

### Is a Peugeot 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 Peugeot bikes have a frame number?

Most Peugeot 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.

### What if the Peugeot 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 Peugeot 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.

### How do I register a Peugeot bike in the UK?

Find the frame number using the locations described above, then record it against your Peugeot. It is free, and you need an account so we know where to send the alert. If that exact number is ever reported stolen to us, we email you. If anyone then lists a bike carrying it, the listing is hidden until the seller proves it is theirs.
