# Where is the frame number on a Voodoo bike? Canonical: https://www.cyclesite.co.uk/trust/frame-numbers/voodoo Last reviewed: 2026-06-11 **Quick answer:** The frame number on a Voodoo bike is most likely to be underneath the bottom bracket, between the pedals. If the bike was bought from Halfords, check the PDI form too. There is no Voodoo-specific prefix to count on, so use the full number on the frame. Most Voodoo bike frame numbers are found underneath the bottom bracket, between the pedals. Because Voodoo bikes are sold through Halfords, the frame number may also be shown on the PDI form supplied with the bike. If you are buying used, ask for the frame number and any Halfords receipt or PDI paperwork. ## Start under the bottom bracket. This is the most common place to find a Voodoo 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 Voodoo registration email or paperwork. - With the Voodoo dealer that sold the bike. ## What a Voodoo frame number looks like A Voodoo frame number should be a unique alphanumeric code on the bike frame. It may be stamped or label-based depending on model and year. Do not use fork, wheel, brake or drivetrain numbers as the frame number. ### Not the frame number - Voodoo Bizango - Voodoo Hoodoo - Voodoo Marasa - Voodoo Braag - Voodoo Limba - Voodoo Nakisi - Voodoo Zobop - Voodoo Canzo - Voodoo Agwe - 29 inch - 27.5 inch - Shimano component code - Suntour fork serial - RockShox fork serial - Wheel serial number - Halfords stock label - PDI reference alone ## The Halfords PDI form The Halfords PDI form is the useful Voodoo-specific paper trail. It should support the frame number, but it should not replace checking the number on the frame itself. ## Buying a used Voodoo 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 Voodoo 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 Voodoo can be a brilliant buy, but the frame number is the detail that protects you. ## Frequently asked questions ### Is a Voodoo frame number the same as a serial number? Yes.
