Asset Tracking Barcodes: How to Tag and Track Gear
Learn how asset tracking barcodes work, which symbology and tag material to use, and how to set up a barcode system to track tools, gear, and equipment.
A barcode on a laptop, a forklift, or a toolbox works differently from the barcode on a box of cereal. Retail barcodes identify a product type that exists in thousands of identical copies. Asset tracking barcodes identify one specific, physical thing, and that single difference shapes which barcode format you pick, what the label is made of, and how you set up the system behind it.
How Do Asset Tracking Barcodes Work?
An asset tracking barcode encodes a unique ID number assigned to one physical item, and that ID points to a record in a database rather than describing the item itself. Scanning the tag pulls up everything else: the asset's location, assigned user, purchase date, warranty status, and service history, all stored separately from the label.
This pointer-based design is also how GS1, the organization behind most global barcode standards, structures its Global Individual Asset Identifier (GIAI). A GIAI combines a company prefix with an asset reference number that the owner defines, and GS1's specifications state the identifier is meant to stay unique "well beyond the lifetime" of the asset, never reused even after it's scrapped or sold. That permanence matters for assets in a way it doesn't for retail products, since an asset's history (who used it, what broke, when it was serviced) needs to stay attached to one unchanging ID for years.
Because the barcode only carries an ID, you can correct a typo in an asset's location or reassign it to a new employee without touching the physical label at all. Only the database record changes.
What Barcode Is Best for Asset Tags?
The best barcode for asset tags depends on your scanning hardware and tag size, not a single universal format. Code 128 and GS1-128 suit general equipment tags read by handheld laser or imager scanners, Data Matrix fits small parts and tools where space is tight, and QR code works best when staff scan with phone cameras instead of dedicated readers.
| Format | Best for | Why |
|---|---|---|
| Code 128 | General equipment, furniture, IT gear | Dense linear code, encodes letters and numbers, read by any handheld scanner |
| GS1-128 | Assets tracked across a supply chain | Code 128 structure with GS1 Application Identifiers for structured data |
| Data Matrix | Small parts, tools, circuit boards | Packs data into a very small, 2D square; strong error correction |
| QR code | Phone-based scanning, field service | Reads reliably from any smartphone camera, no dedicated hardware needed |
| Code 39 | Legacy scanner fleets | Older, less dense format still supported by older laser scanners |
Camcode, a manufacturer of industrial asset labels, frames Data Matrix as the format of choice for small, high-durability industrial tags because of how little physical space it needs for a given amount of data. That tradeoff is real, but it only matters if your assets are genuinely small or your scanners genuinely support 2D codes. For most equipment and furniture tracking, a Code 128 or GS1-128 label scanned with any handheld or phone-based scanner, including a free option like barcodescanner.online, works just as well and is simpler to print in-house.
What Material Should Asset Tags Be Made From?
Tag material matters more for asset tracking than for almost any other barcode use case, since the same physical label has to survive for years, not just until a product sells. Polyester labels handle most indoor equipment affordably, while anodized aluminum tags are built for outdoor exposure, heat, and heavy handling.
Camcode's product literature describes its anodized aluminum tags (sold under the brand name Metalphoto) as having the barcode image sealed inside the anodic layer of the metal itself, rather than printed on top of it, which is why the company rates these tags as remaining readable outdoors for decades and resistant to sunlight, moisture, and chemical exposure. That construction is why metal asset tags show up on vehicles, outdoor utility equipment, and machinery that lives in harsh environments.
For indoor IT equipment, office furniture, and general tools, a polyester label is more practical and far cheaper. Many vendors also offer tamper-evident or "void" versions in polyester or vinyl that leave a visible pattern behind if someone tries to peel and move the tag, which helps catch asset reassignment that wasn't logged in the system.
What Is the Difference Between Asset Tags and Inventory Barcodes?
An inventory or SKU barcode identifies a product type, so every identical unit shares the same code, while an asset tag identifies exactly one physical item and is never reused. This distinction is built directly into barcode standards, not just common practice.
GS1 maintains separate identifier keys for each purpose: the GTIN (Global Trade Item Number) for products and trade items, and the GIAI (Global Individual Asset Identifier) for individual assets. GS1's own specifications are explicit that a GIAI "must never be used to identify the entity as a trade item," keeping the two systems cleanly separated. In practice, that means a pallet of 500 identical office chairs might share one SKU barcode for ordering purposes, but each chair gets its own unique asset tag once it's assigned to a desk, because only the asset tag needs to track that specific chair's location and condition over time.
If you're tagging items that stay in your business long-term, like equipment, tools, and furniture, use the asset-tag approach. For products you buy and resell as interchangeable units, stick with standard inventory barcoding.
How Do I Set Up a Barcode Asset Tracking System?
Setting up asset tracking barcodes means choosing a symbology and tag material first, then building the numbering scheme and database before you print a single label. Skipping straight to printing tags without a numbering plan is the most common mistake, since renumbering hundreds of already-applied tags later is far more work than planning it up front.
- Pick your barcode format and tag material based on your scanner type and the asset's environment (see the sections above).
- Design a numbering scheme. A sequential scheme (ASSET-0001, ASSET-0002) is simplest. A hierarchical scheme that encodes location or department into the ID (for example, WH1-ELEC-0042) makes assets easier to sort at a glance, but either way, no two assets should ever share an ID.
- Build your asset register. A spreadsheet works for smaller operations; dedicated asset-management or CMMS software suits larger fleets. Each row should hold the asset ID plus description, owner, location, and purchase details.
- Apply and scan in every tag. Place labels in a consistent spot on each asset type (the same corner or panel every time) so staff can find and scan them quickly, and scan each one into the register as you apply it.
- Schedule regular audits. Periodic scans against the register catch assets that moved, were disposed of, or never got logged in the first place.
