A valid product identifier under the General Product Safety Regulation (EU) 2023/988 (GPSR) is a clear, unique reference that lets authorities and supply chain partners trace a specific consumer product and, where relevant, its production run. In practice, this is usually a model number plus a batch or serial number that distinguishes units or lots.
For GPSR traceability, the identifier must be consistent across the product, packaging, and supporting documentation so a market surveillance authority can quickly match what is being sold to the correct technical file and safety information. This matters most for non-EU brands and online sellers that ship directly to EU consumers.
The questions below break down what counts as a product identifier, which formats are typically accepted, and where you should place it to meet GPSR traceability expectations.
What is a product identifier under the GPSR?
A product identifier under GPSR is a label or reference that uniquely links a product placed on the EU market to its manufacturer, type, and traceability information. It should enable fast identification of the exact product version and, when needed, the specific batch or individual unit for corrective actions, recalls, and accident investigations.
Think of the product identifier as the anchor that ties together your product listing, the physical item, and your product safety documentation. GPSR traceability works best when the identifier is stable over time and not dependent on a marketplace listing number that can change.
A strong identifier usually answers three practical questions for an authority:
- What product is this exactly (type or model)?
- Which production run or unit is it (batch or serial number)?
- Which economic operator can provide the documentation quickly (for example, the manufacturer and the EU-based Responsible Person)?
Because GPSR applies broadly to consumer products, the identifier should be chosen so it remains readable and usable under normal conditions of use and distribution.
Which identifiers are typically accepted for GPSR traceability?
Identifiers typically accepted for GPSR traceability are those that uniquely distinguish the product type and, where relevant, the production lot or individual unit. Commonly accepted options include a model number, a batch or serial number, and sometimes a scannable code that resolves to the same underlying identifier, as long as it is consistent and unambiguous.
In most compliance reviews, the safest approach is to combine a model or item number with a batch or serial number. That combination supports both day-to-day traceability and targeted corrective action if a safety issue appears in a specific production run.
- Model number or SKU that identifies the product type and version
- Batch or lot number that groups units made under similar conditions
- Serial number that uniquely identifies an individual unit
- Scannable codes such as QR or Data Matrix that encode or point to the same model and batch or serial number
Be careful with identifiers that are not stable. Marketplace listing IDs, internal order numbers, or shipping tracking numbers usually do not work as the primary product identifier because they can change and they do not reliably map to a specific product version.
Also ensure the identifier format is controlled. If you change model naming conventions, reuse batch codes, or apply different identifiers across factories, you can create traceability gaps that slow down responses to authority questions and increase the risk of delisting by online platforms.
Where must the product identifier appear (product, packaging, or documents)?
The product identifier should appear on the product itself whenever feasible, and otherwise on the packaging or an accompanying document, in a way that remains accessible to the end user and authorities. For GPSR traceability, the key is that the identifier on the item being sold matches the identifier used in your documentation and supply chain records.
In practice, you should aim for a consistent placement strategy that survives real-world handling. Many products can carry a durable label, engraving, or printed mark. If the product is too small or the material makes marking impractical, packaging and enclosed documentation become more important.
- On product when size and nature allow, using a durable and legible mark
- On packaging as a backup and for products where direct marking is not feasible
- In accompanying documents such as instructions for use or safety information, matching the same identifier
- In technical documentation and internal records so you can retrieve the correct file quickly when requested
Consistency matters more than creativity. If the product shows only a model number but the packaging shows a different SKU, and your technical file uses yet another identifier, you create friction during checks and during any accident follow-up.
Finally, remember that traceability is not only about the identifier. You also need a reliable process to connect that identifier to the correct documentation set and to the EU-based economic operator that can respond to authority requests under the Market Surveillance Regulation (EU) 2019/1020 (MSR).
