What is a Track and Trace Code?
A track and trace code is a unique identifier – typically a serial number, barcode, Data Matrix, or QR code – printed or laser‑marked on a product, its packaging, or a security label. When scanned at different points in the supply chain (factory, warehouse, distributor, retailer, or by the consumer), the code records the product’s location, time, and status in a centralised cloud database. This creates a digital audit trail, enabling brands, regulators, and consumers to verify the product’s authenticity, track its journey from origin to destination, and detect counterfeits or diversion (grey market sales). Track and trace codes are a core component of pharmaceutical serialisation (e.g., EU FMD, India’s export rules), electronic warranty management, automotive spare parts authentication, and luxury brand protection. When combined with a hologram label (overt security), the track and trace code adds a digital layer of authentication, making it extremely difficult for counterfeiters to pass off fake goods. Holoseal integrates custom track and trace codes – sequential or random serial numbers, 1D barcodes, 2D QR codes, and GS1‑compliant Data Matrix – into our hologram labels, providing a complete phygital (physical + digital) security solution.
🔍 How a Track and Trace Code Works (Step‑by‑Step)
- Code generation – Each product unit receives a unique code (e.g., “HOL123456789”). The code may be sequential (0001, 0002…) or random/encrypted.
- Printing / marking – The code is printed (inkjet, thermal transfer, laser) or laser‑demetalized onto a hologram label or directly on the packaging.
- Database registration – All codes are uploaded to a secure cloud database with a status of “manufactured” or “not yet shipped”.
- Scan at factory outbound – When the product leaves the factory, the code is scanned. The database records “shipped” with a timestamp and location.
- Scan at distributor / retailer – Each subsequent scan updates the product’s journey. If the code is scanned in an unexpected location (e.g., a product meant for India scanned in Nigeria), an alert is triggered.
- Consumer verification (optional) – The end customer scans the QR code with a smartphone. The verification page shows “Authentic – first scan” or “Warning – this code has been scanned before.”
🛡️ Types of Track and Trace Codes Used on Hologram Labels
- Sequential human‑readable numbers – Simple numeric codes (e.g., 000001, 000002). Easy to read but can be guessed.
- 1D linear barcodes (Code 128, Code 39, EAN‑13) – Machine‑readable, used for warehouse and retail scanning. Can store product identifiers and batch numbers.
- 2D Data Matrix codes – Square, high‑density codes that store up to 2,335 characters. Most common for pharmaceutical serialisation (GS1 standard).
- QR codes (Quick Response) – Square codes that can store a URL, serial number, or encrypted data. Easily scanned by smartphones – ideal for consumer authentication.
- GS1‑128 linear barcode – Specialised 1D barcode that encodes GS1 application identifiers (batch, expiry, serial number).
- Composite codes (1D + 2D) – Both a linear barcode and a 2D code in one label, for compatibility with legacy and modern scanners.
🔐 Why Track and Trace Codes Are Essential for Brand Protection
- Counterfeit detection – A fake product using a copied code will be detected when the same code is scanned multiple times.
- Anti‑diversion (grey market) – Products intended for one market (e.g., India) are scanned in another country (e.g., Africa) – the brand receives an alert.
- Recall management – In case of a defect, only specific serial numbers need to be recalled, not entire batches.
- Consumer trust – A simple QR scan reassures the buyer that the product is genuine and not tampered with.
- Regulatory compliance – Many industries (pharmaceuticals, tobacco, alcohol) require track and trace by law.
📦 Track and Trace Code vs. Serial Number – What’s the Difference?
- Serial number – A unique number assigned to a product. It may be human‑readable only.
- Track and trace code – Usually a machine‑readable barcode or QR code that encodes the serial number (and often batch, expiry, etc.). The term “track and trace code” emphasises the system of scanning and recording, not just the number itself.
⚙️ How Holoseal Integrates Track and Trace Codes into Hologram Labels
We offer several methods to add variable track and trace codes to security hologram labels:
- Digital overprinting (inkjet / thermal transfer) – Print unique QR codes or serial numbers on each label. Suitable for runs up to 100,000 labels and where numbers change frequently.
- Laser demetalization – A laser removes the aluminium layer in the shape of the barcode or text. Extremely durable, cannot be scratched off. Ideal for harsh environments.
- Pre‑printed variable data with numbering heads – For very large runs (millions), a specialised press can print sequential numbers at high speed.
- Combined with tamper‑evident adhesive – The label is VOID or destructible, so any attempt to peel it destroys the code.

❓ Frequently Asked Questions About Track and Trace Codes
Are track and trace codes mandatory for all products?
No – they are mandatory for pharmaceuticals in many countries (EU, US, India for certain drugs), for tobacco products, and for alcohol in some jurisdictions. Other industries adopt them voluntarily for brand protection.
Can a track and trace code be duplicated?
If a counterfeiter copies a genuine code onto many fake products, the first genuine scan will show “authentic”, but subsequent scans will trigger “code already used – possible counterfeit.” To minimise this, many brands use scratch‑off codes or limit the number of allowed scans (e.g., one scan per code).
What is the difference between track and trace and serialisation?
Serialisation is the assignment of unique numbers. Track and trace is the process of scanning those numbers at checkpoints to track the product’s journey. Serialisation enables track and trace.
Do I need internet access to verify a track and trace code?
Yes – for digital verification (QR scan), an internet connection is required to query the cloud database. However, the overt hologram on the same label provides off‑line authentication by tilt test.
How durable are printed track and trace codes on hologram labels?
Printed codes (inkjet/thermal transfer) can be scratched or dissolved. For long‑term or harsh environments, we recommend laser‑demetalized codes (permanent, cannot be removed).
