The Importance of Your E-Scooter’s Frame Number

Apr 18, 2025 David

Every KuKirin e-scooter has a unique alphanumeric code engraved on the frame or battery compartment. While it may seem like a simple detail, this number is your ultimate safeguard:

Key to After-Sales Service

The frame number links directly to the manufacturer’s database, providing instant access to production details, warranty status, and repair history. Without it, service delays or even denied claims may occur.

Theft Recovery Tool

Registered in brand and some local traffic systems, this code helps authorities track stolen scooters by monitoring resale platforms and repair shops. Unlike removable parts, the laser-etched or embedded code is tamper-proof, making it a reliable theft deterrent.

Insurance Requirement

Insurers use the frame number to verify ownership and prevent fraud. In case of accidents, it speeds up claims by confirming the vehicle’s identity. Some smart policies even sync riding data via this code for dynamic pricing.

3 Rules to Protect Your Frame Number

Save a Copy: Take a clear photo and back it up digitally.

Shield It: Apply a transparent sealant or film to prevent wear.

Keep It Private: Blur the code in social media posts to avoid misuse.

Choosing KuKirin means trusting quality; safeguarding your frame number means protecting that trust. Next time you clean your scooter, check this "digital shield"—it’s your silent guardian on every ride.
