Sequential numbering and series
Number ranges reserved for the customer, with duplicate control and check digits.
Read moreSerialization, QR codes and variable data for labels
Many labels carry different data on each unit: a serial number, a QR or DataMatrix code, a batch or a verification link. This page explains how we prepare the data that goes with the printed label, so that the production partner receives a clear, reviewed file.
Every service on this page is optional: the scope of each project, including any online verification page, is defined and confirmed in the offer.
What we can prepare
Seven capabilities that can be combined in a single project. Each one links to the product page or category that describes the label.
Unique QR and DataMatrix codes
A different code on each unit, printed with variable data. The choice between QR and DataMatrix depends on the reading system and on what the code must contain.
Read moreVariable-data file
Validation of the customer’s CSV file and conversion to the variable-data file used by the factory: format, field length, duplicates and ranges.

GS1 Digital Link
A QR whose content is a GS1 Digital Link: the GTIN and, optionally, the batch, serial number or expiry date. The GS1 identifiers are supplied by the customer.

Online verification page (optional)
A page in Spanish, English and Portuguese that shows whether a code exists, with a repeat-scan alert based on a rule agreed with the customer, statistics by region or channel and a customer dashboard. The scope is defined and confirmed in the offer.

Combinable security layers
The code can be combined with a scratch-off PIN layer, a hologram, a VOID label or NFC, depending on the project.

Data carriers for the digital product passport
Labels with QR, DataMatrix or NFC that act as the data carrier and link to the customer’s platform. The platform and the data are managed by the customer or their provider.
Read moreHow we work with your data
- The customer sends the list of references (SKUs), the numbering rules and, if available, a sample file.
- The code type, its content and the file format are agreed.
- The file is reviewed: format, duplicates and ranges. Any issues are reported to the customer before production.
- The customer approves the proof with sample data; the production partner prints from the approved file.
- If the project includes online verification, the page is prepared with the approved list of codes.
Who defines the data
The content of the data is defined by the customer and the production partner reproduces the file the customer has approved.
The legal content of the label is defined by the customer; we reproduce the artwork the customer has approved and signed.
Options depending on the project
- Verification of the code quality grade (ISO/IEC 15415 or ISO/IEC 29158), with the evaluation method and sampling agreed in the offer.
- Code content: a URL, a unique identifier (for example from the ISO/IEC 15459 series) or a GS1 structure.
- Thermal-transfer or digital variable-data printing on paper, PP, PET or vinyl.
- A proof with sample data for your approval before production.
- Weather-resistant materials, if the environment of use requires it.
Personal data and reference rules
If the verification page records the IP address or location of the person scanning, people must be informed, under Regulation (EU) 2016/679 (GDPR). The controller, the hosting and the retention period of the scan data are defined per project.
References usually consulted: ISO/IEC 15415 and ISO/IEC 29158 (code quality), ISO/IEC 15459 (unique identification, if adopted) and the GS1 specifications. Only their name and number are given.
What we need to quote
- List of products (SKUs) and annual consumption.
- Code type (QR, DataMatrix, GS1) and its content.
- Numbering rules, duplicate control and check digits.
- A sample CSV file with the variable data.
- Material, application method and the security layers you want.
- If you need online verification: languages, hosting, data retention period and repeat-scan rule.
- GDPR requirements and whether you already use an ERP or GS1 codes.
Frequently asked questions
What data should I send to order serialized labels?
A sample CSV, the code type and content, the numbering rules with duplicate control and check digits, and the code quality requirements. From there we prepare the variable-data file for the factory.
Do you host the online verification page?
It is an option and its scope depends on the project. Tell us whether you need it hosted, in which languages and for how long the data must be kept; the scope is defined and confirmed in the offer.
Does a QR code on its own protect against copying?
No. According to the EUIPO, QR codes by themselves do not offer protection against copies, but they can be combined with other authentication technologies, such as holograms, copy detection patterns or unique identifiers.
Can I use my own GS1 codes?
Yes. The GS1 identifiers (GTIN) are supplied by the customer and included in the data file. The content of the label is defined by the customer.
