Why organizations tag assets
A manufacturer's serial number shows which unit was built in the factory. It does not show who holds the device, which department paid for it or when it should be replaced. The organization must answer those questions itself. An asset tag fills that gap: it is a number the organization controls, assigned when a device enters service, and it stays linked to the record for as long as the organization owns the device.
A tag also holds up where other identifiers fail. A laptop's serial number sits on a sticker that can fade or hide under the unit. A drive replaced under warranty gets a new serial number while the computer stays the same. A durable, visible tag on the chassis keeps the inventory number constant, whatever happens to the parts inside. Tags work best as one identifier inside an IT asset management program, not as a standalone sticker.
Common tag formats
Whatever the format, the physical label is only half of the system. It gains meaning only alongside a software record, such as a configuration management database, that stores what the number refers to, who is responsible for it and where it should be.
| Format | How it works |
|---|---|
| Barcode label | Linear barcode on a tamper-evident label, read by handheld scanner |
| QR code label | Scanned with a phone camera, often linking to the asset record |
| RFID tag | Read by radio without line of sight, preferred for large estates |
| Engraved or embossed tag | Number stamped or etched into metal, for outdoor gear and rough handling |
How a tag enters the inventory
A tag is useful only if it is attached and recorded on the day the device enters service. Otherwise the count and the physical stock drift apart within months.
- 1
Assign
Issue a unique number from the organization's own sequence before the device goes to a user.
- 2
Attach
Fix the label to the chassis in a visible place that survives cleaning and transport.
- 3
Record
Enter the number on the device card next to the serial number, owner, and location.
- 4
Review
Compare physical labels with the records at each audit and investigate what does not match.
What tags make possible
Once a device carries a tag, the same number supports several routine tasks:
- Physical audits: walk a floor with a scanner and check what is present against the inventory system, instead of assuming nothing has moved.
- Ownership: when a device is reassigned, the tag stays and the holder record changes, so a lost item has a traceable last known custodian.
- Lifecycle and finance: purchase date, warranty, depreciation, and disposal date attach to the tag number, which accounting and IT both reference.
- Maintenance: repairs, part swaps, and support tickets are logged against the tag, not against a component serial that may have changed.
Grouped and compound items
Not every tagged object is a single computer. A workstation, its monitor, docking station, and keyboard can be issued as one bundle and tracked under a single asset tag, if the organization prefers to manage them as one unit.
The reverse also applies. One large machine can carry several tags if its main components, such as a server chassis and the drives inside it, are tracked and depreciated separately. The tagging scheme must match how the organization accounts for equipment, not just how it is physically assembled.
What it looks like in Anexet
In Anexet Inventory, the Devices tab of a workstation card lists the hardware found on the machine, with the device type and manufacturer of each component. A tagged computer can be checked against its real parts, so a swapped component is easier to spot.
Limits and failure modes
A tag is only as good as the discipline around it. Labels peel off or get painted over, and a tag on a component that later moves to another chassis silently detaches the number from the object it was meant to identify.
New equipment that goes straight into use without a tag creates a gap the inventory count never closes. An untagged device that appears on the network is a rogue device until someone identifies it. For this reason, tags are cross-checked against serial numbers, hostnames, and what is actually connected, not treated as the only source of truth.
A tag that nobody checks against the network is only a sticker.
Where to start
Tag the assets that would cost the most if they were lost or misreported first, then review the tags against the network on a fixed schedule. A label that nobody checks is just decoration.
A tag is a promise that the record and the object still belong together.
Anexet TeamHow Anexet handles this
In Anexet, the inventory number field is the organization's own asset tag, carried alongside the manufacturer's serial number rather than in place of it:
That keeps the physical label on a device and its digital record moving together, even as components inside the device change.
Inventory number on every device card
each device and computer card records an inventory number next to its serial number, manufacturer, and description, so the organization's own tag and the manufacturer's identity are both visible in one place.
Compound devices under one tag
several components can be grouped into a compound device sharing one inventory number, matching how an organization actually bundles a workstation, monitor, and dock as a single accountable unit.
Ownership and status fields
each device carries a status, a responsible person, and an organizational placement down to department and workplace, so the tag number resolves to a current owner, not just a static asset description.
Audit trail
every addition, deletion, move, and status or ownership change is recorded in a full, attributable log, so a tag's history can be reconstructed rather than taken on trust.
