The
key to the OPC system is the unique code and machine-readable symbol assigned
to every product. This code allows simpler and more accurate product
identification. The symbol makes possible the use of scanner-equipped data
entry devices.
The OPC is a 10-digit, numeric code that identifies the
product and the manufacturer. The structure of the OPC code is the following:
-
5 digits for Manufacturer Identification Number assigned by the Optical Product
Code Council, Inc.
-
4 digits Item Identification Number assigned and controlled by the optical
manufacturer. The item identification number must be unique to each individual
product
-
1 digit for checksum which is automatically calculated by Barcode Professional
