Since 1984, National Bike Registry (NBR) has been working with law enforcement nationwide to return stolen bikes to their owners. It is now powered by BoomerangIt, the global lost and found service for all property. NBR provides free secure access to its database to law enforcement to look up recovered bicycles' serial numbers and description to identify and locate their owners. NBR also provides free support materials on bike registration and safety for law enforcement to register bikes in their jurisdiction and distribute among community members.
