Why Every Tree Deserves a Unique ID: GZ-TIN Explained

What is GZ-TIN?

GZ-TIN stands for Groundzy Tree Identification Number. It's a unique ID assigned to every tree in your inventory—for example, GZ-ABC12-12345. Like a VIN for a car or a serial number for equipment, a GZ-TIN lets you refer to one specific tree and track its history over time.

Why Unique IDs Matter for Trees

Without a unique ID, "the oak by the driveway" could mean different things to different people—or to the same person years later. A GZ-TIN eliminates ambiguity. You can record pruning, health assessments, treatments, and removals for that exact tree, and anyone with the ID can pull up its full record. This is essential for professional tree inventory management.

Benefits by User Type

• Homeowners: Reference specific trees when talking to arborists or landscapers. Track care history for each tree on your property.
• Arborists: Document every service with a tree ID. Create professional reports for clients. Maintain an audit trail for compliance and liability.
• Property managers: Organize trees across multiple properties. Share IDs with vendors so everyone is talking about the same tree. Support compliance reporting and asset tracking.
• Municipalities: Track urban forest health, maintenance schedules, and removals. Produce reports for city councils and the public.

Lifecycle Tracking

A GZ-TIN follows a tree from planting (or when you first add it) through every pruning, treatment, and health check—all the way to removal. Service history, photos, measurements, and notes stay attached to that ID. When you export reports or share data with clients, the tree's identity and history travel with it.
