How do beginners use the Product Identity Code (PID)? Complete Operating Guide
A beginner-friendly guide to using product identity codes (PID), from merchant registration, entity verification, product creation and PID generation to label printing and scan verification, helping merchants quickly get started with product digital identity.
It is used for information collation, scanning code display, evidence filing and risk warning; it does not claim official certification, nor does it replace formal compliance review.
A beginner-friendly guide to using product identity codes (PID), from merchant registration, entity verification, product creation and PID generation to label printing and scan verification, helping merchants quickly get started with product digital identity.
First, understand: What is a Product Identity Code?
A Product Identity Code (PID) can be understood as a unique, verifiable identifier assigned to each product.
But its value is not just that it “can be scanned”, but rather:
- Each product has a unique identity
- Scan actions can be recorded
- Verification records can be reviewed later
Therefore, the core of PID is not just a code, but a complete system of “product identity + verification records”.
Step 1: Register an account and complete entity verification
To use Product Identity Codes, you must first register as a platform merchant.
After registration, you need to submit entity information for verification, such as:
- Company or individual entity information
- Industry category
- Country and trade type
- Compliance declaration
This information will serve as the foundational data for your product identities.
After submission, the platform will review it. Once approved, you can officially use the system.
Step 2: Create products and complete information
After verification is approved, you can enter product management and create your products.
Here is a key point: different products and trade types will have corresponding “required fields”.
The system will automatically determine:
- How many fields are required for the current product
- How many fields have already been completed
- Whether the conditions for generating a PID are met
If the fields are incomplete, the product will be marked as “Incomplete” and cannot proceed to the next step.
Step 3: Generate the Product Identity Code (PID)
Once the product information is complete, you can generate a PID for the product.
This involves three key mechanisms:
- PID quota (each merchant has an available allocation)
- Batch generation (each generation belongs to a batch)
- Status control (generating / completed / rolled back)
The system will first reserve the quota, then generate PIDs in batches, and record the entire process to ensure data security and traceability.
Step 4: Select a label template and export
After generating the PID, it is not used directly — it must be “applied” as a label.
You can:
- Select an official label template
- Lock the template style
- Export a ZIP file for printing
Note: Once exported, the template will be locked to prevent confusion later.
Step 5: Apply labels and enter real usage scenarios
After printing, attach the labels to the product or its packaging.
Common placement locations include:
- Product outer packaging
- Seal labels
- Hang tags or instruction cards
Once this step is completed, the product officially enters a “verifiable state”.
Step 6: Users scan and generate verification records
When users scan the code, the system will:
- Display basic product information
- Record the verification action
- Generate verifiable records for future review
The most critical point here is:
Summary: The complete path from zero to using PID
- Register an account and complete entity verification
- Create products and complete information
- Generate PID (identity code)
- Select a template and export labels
- Apply labels and enter circulation
- Scan to generate verification records
Once you complete this entire process, your product is no longer just an “ordinary product” — it now has a complete digital identity and verification record capability.
You can start with a key product, establish a product identity page, organize supporting materials, record scan scanning verification results, and then gradually upgrade to a more complete DPP preparation process as needed.
