Understand product barcodes

Understand the difference between supplier barcodes and LaSyncro product labels.

Quick answer

LaSyncro can work with two separate product identifiers:

  • a supplier barcode such as an EAN, UPC, or GTIN;
  • a LaSyncro product label with an identifier beginning with LSP-.

These are separate barcode namespaces. A product can have one or both.

Supplier barcodes

Supplier barcodes are external product identifiers.

In LaSyncro, the supplier barcode is kept separately from the LaSyncro-generated product identity.

LaSyncro does not generate replacement EAN, UPC, or GTIN values.

LaSyncro product labels

A LaSyncro product label uses an identifier beginning with:

LSP-

LaSyncro creates this internal product identity when a product label needs to be printed and the variant does not already have one.

The generated value is stored against that product variant.

A product can have both

An LSP code does not replace a supplier barcode.

A product that already has a supplier EAN or UPC can still have a LaSyncro label, for example when you need another physical label for warehouse use.

The two identifiers remain separate.

Reprinting a LaSyncro label

Once an LSP identity has been created, LaSyncro keeps it.

Reprinting the product label uses the same LSP code rather than generating a new identity.

This means labels already applied to the product remain tied to the same product variant.

Products without supplier barcodes

A missing supplier barcode does not prevent you from creating a printable LaSyncro product label.

LaSyncro can mint an LSP identity when you print the product label.
