IT asset tagging without serial number verification only confirms that a sticker exists—it does not confirm that the right asset exists.
Many organizations believe that once a QR Code or Barcode has been pasted on a laptop, desktop, printer or server, the asset has been properly verified. Unfortunately, that assumption is not always correct.
A professionally executed IT asset verification exercise should establish a reliable link between four critical elements:
- The physical asset
- The manufacturer’s serial number
- The Fixed Asset Register (FAR)
- The actual user or custodian
Only when all four match can an organization confidently say that its IT asset records are accurate.

Introduction
Imagine this situation.
A company purchases 500 laptops over three years. Every laptop is capitalized in the books, entered into the Fixed Asset Register (FAR), and eventually receives an asset tag.
A few years later, the company decides to conduct a physical verification of its IT assets.
Everything appears perfect.
Every laptop has an asset tag.
Every employee has been assigned a laptop.
The Fixed Asset Register looks complete.
Many service providers would simply scan the asset tag, update the register and move on.
At Tag My Assets, this is where our actual verification begins.
Instead of relying only on the QR sticker pasted on the laptop, our team first verifies the manufacturer’s serial number directly from the operating system and matches it with the Fixed Asset Register before confirming or applying a new asset tag.
This additional step often identifies discrepancies that remain unnoticed for years.
The objective of IT asset tagging is not merely to paste a sticker.
The objective is to ensure that the laptop physically available with the employee is the same laptop recorded in the organization’s Fixed Asset Register.
Asset Tagging vs IT Asset Verification
Many organizations use these two terms interchangeably.
They are not the same.
| Basic Asset Tagging | Professional IT Asset Verification |
|---|---|
| Paste QR/Barcode sticker | Verify physical availability |
| Record asset number | Verify Make & Model |
| Update spreadsheet | Verify manufacturer serial number |
| Scan QR code | Match serial number with FAR |
| Complete tagging | Verify user allocation |
| Finish work | Capture discrepancies and update records |
Anyone can paste a QR Code.
Professional verification confirms that the QR Code belongs to the correct asset.
That difference may appear small, but it significantly improves the quality of the organization’s asset records.
Why the Manufacturer’s Serial Number Matters
Every laptop or desktop is assigned a unique serial number by the manufacturer.
Unlike an internally generated asset number, the manufacturer’s serial number acts as the permanent identity of the device.
Asset tags can be removed.
Asset numbers may change.
Employees may exchange laptops.
Departments may relocate assets.
But the manufacturer’s serial number continues to identify the original device.
During verification assignments, we have observed situations where the asset tag matched the Fixed Asset Register perfectly.
However, after checking the manufacturer’s serial number, we discovered that the laptop itself had been replaced several years earlier without updating the records.
The employee was using a different laptop.
The asset tag belonged to another device.
Without serial number verification, the discrepancy would never have been identified.
Why We Verify the Serial Number Through the Operating System
Many laptops have damaged or faded manufacturer labels.
Sometimes previous asset stickers completely cover the original label.
In many cases, the label becomes unreadable after years of usage.
Instead of depending only on the physical label, our verification team retrieves the serial number directly from the operating system.
For Windows devices, PowerShell can be used:
Get-CimInstance Win32_BIOS | Select-Object SerialNumber
Older Windows versions may also support:
wmic bios get serialnumber
For macOS devices, the serial number can be viewed from:
Apple Menu → About This Mac
or through Terminal:
system_profiler SPHardwareDataType
Reading the serial number directly from the operating system improves accuracy and minimizes manual recording errors.
Common Discrepancies Identified During IT Asset Verification
Serial number verification often reveals discrepancies that cannot be identified by visual inspection alone.
1. Laptop Replacement Without Updating Records
A laptop may have been replaced during warranty support or internal IT maintenance.
The employee is using the replacement laptop.
However, the Fixed Asset Register still contains the serial number of the original device.
Unless the serial number is verified, the discrepancy remains hidden.
2. Incorrect Asset Mapping
Sometimes two identical laptops accidentally receive each other’s asset tags.
The laptops physically exist.
The asset tags also exist.
But the mapping between the laptop and the register is incorrect.
Only serial number verification can identify this issue.
3. Duplicate Asset Records
During IT asset verification, it is not uncommon to find duplicate records in the Fixed Asset Register. This usually happens when organizations migrate from one ERP or asset management system to another, or when manual entries are made without proper validation.
For example, the same laptop may appear twice in the register under different asset numbers. While this may seem like a simple data entry error, it can result in incorrect depreciation, inaccurate asset counts, and unnecessary confusion during audits.
Serial number verification helps identify such duplicate records quickly because every genuine device has only one manufacturer’s serial number.
4. Wrong User Allocation
In many organizations, laptops are exchanged between employees without informing the IT or finance department.
As a result, the Fixed Asset Register may show Laptop A with Employee X, while the device is actually being used by Employee Y.
Although the asset physically exists, the organization’s records are no longer reliable.
Updating user allocation during physical verification improves accountability and simplifies future audits.
5. Incorrect Serial Numbers in the Fixed Asset Register
Sometimes the laptop itself is correct, but the serial number recorded in the FAR contains typing errors or incomplete information.
A single incorrect character can make future identification difficult.
By validating the serial number directly from the operating system, such errors can be corrected immediately.
Why This Matters to Management
Many people think serial number verification is only useful during an audit.
In reality, it provides benefits throughout the asset’s lifecycle.
Accurate serial number mapping helps in:
- Warranty claim management
- Annual Maintenance Contract (AMC) management
- Insurance claims
- Theft investigations
- Employee handovers
- Device replacement planning
- IT helpdesk support
- Asset disposal
- Financial reporting
A reliable Fixed Asset Register benefits not only the finance department but also IT, administration, procurement, and internal audit teams.
A Practical Example
Consider an organization with 2,000 laptops.
If only 2% of those laptops have incorrect serial numbers recorded in the Fixed Asset Register, nearly 40 devices cannot be reliably identified.
Now imagine the challenges during:
- Statutory Audit
- Internal Audit
- Insurance Claim
- Warranty Replacement
- Cyber Security Investigation
- Employee Exit
A simple serial number verification exercise can prevent these problems long before they become expensive.
Our IT Asset Verification Methodology
At Tag My Assets, IT asset verification follows a structured process designed to ensure that the physical asset and the accounting records represent the same device.
Step 1 – Physical Verification
Locate the laptop or IT asset and verify its physical availability.
Step 2 – User Verification
Confirm the employee, department and location where the asset is currently being used.
Step 3 – Make & Model Verification
Record the manufacturer, model number and other identifying details.
Step 4 – Serial Number Verification
Retrieve the manufacturer’s serial number directly from the operating system and compare it with the Fixed Asset Register.
Step 5 – FAR Matching
Verify whether the serial number, asset description and asset code match the organization’s records.
Step 6 – Resolve Discrepancies
Identify and document differences such as:
- Wrong user allocation
- Wrong serial number
- Wrong asset code
- Duplicate records
- Unrecorded replacement
- Missing assets
- Additional assets
Step 7 – Asset Tagging
Only after successful verification is a QR Code, Barcode or RFID tag applied to the asset.
This ensures that the tag is linked to the correct device.
Step 8 – Data Capture
Capture all relevant information, including:
- Asset ID
- Make
- Model
- Serial Number
- User Name
- Department
- Location
- Condition
- Asset Photograph
The updated information forms the basis for an accurate Fixed Asset Register.
Benefits of Professional IT Asset Verification

Frequently Asked Questions (FAQs)
1. What is the difference between IT asset tagging and IT asset verification?
IT asset tagging is the process of assigning a unique identification number (QR Code, Barcode or RFID tag) to an asset.
IT asset verification goes much further. It confirms the physical existence of the asset, validates the manufacturer serial number, verifies the user and location, and matches all these details with the Fixed Asset Register (FAR).
In simple words, tagging identifies the asset, while verification confirms its identity.
2. Why should the serial number be verified through the operating system?
The manufacturer’s sticker on a laptop may become faded, damaged or covered by other labels over time.
Retrieving the serial number directly from the operating system provides a reliable source of identification and helps eliminate manual recording errors.
It also allows organizations to verify that the physical device matches the Fixed Asset Register.
3. Can serial number verification help detect record discrepancies?
Yes.
Serial number verification frequently identifies discrepancies such as:
- Incorrect serial numbers recorded in the FAR
- Laptop replacements not updated in records
- Wrong user allocation
- Duplicate asset records
- Incorrect asset mapping
- Documentation errors following repairs or warranty replacements
Most of these issues arise because records are not updated promptly, not necessarily because an asset is missing.
4. Is serial number verification useful only during audits?
No.
Serial number verification adds value throughout the asset lifecycle.
It helps in:
- Annual physical verification
- Internal and statutory audits
- Warranty management
- Insurance claims
- Employee transfers
- Device replacement planning
- Asset disposal
- IT governance
Organizations with accurate serial number records spend significantly less time resolving asset-related issues.
5. Should every IT asset be tagged?
Ideally, yes.
Laptops, desktops, servers, printers, networking equipment, monitors, projectors and other valuable IT assets should have a unique asset identification number linked to the Fixed Asset Register.
When asset tagging is combined with serial number verification, organizations achieve much higher accuracy in their asset records.
Final Thoughts
Over the years, one lesson has remained consistent across every IT asset verification assignment.
Most discrepancies are not caused because assets are missing.
They exist because asset records are incomplete, outdated or not updated after changes take place.
A laptop gets replaced under warranty.
An employee changes departments.
A desktop is shifted to another office.
A monitor is exchanged between users.
The asset continues to exist.
Only the records fail to keep pace.
Unfortunately, those small documentation gaps gradually become major audit observations, warranty issues and asset management challenges.
That is why professional IT asset verification should never be limited to attaching a QR sticker.
Every asset should be verified using its manufacturer serial number, matched with the Fixed Asset Register, confirmed with the actual user and then tagged with a unique asset identification number.
This simple approach significantly improves the reliability of asset records and strengthens internal controls.
Because at the end of the day,
A QR Code identifies an asset.
A manufacturer’s serial number confirms its identity.
Together, they create a Fixed Asset Register that management, auditors and stakeholders can trust.
