Frequently Asked Questions

How does the EPC work?

The EPC is a string of numbers and letters, consisting of a header and three sets of data partitions. The first partition identifies the manufacturer. The second identifies the product type (stock keeping unit) and the third is the serial number unique to the item. By separating the data into partitions, readers can search for items with a particular manufacturer’s code or product code. Readers can also be programmed to search for EPCs with the same manufacturer and product code, but which have unique numbers in a certain sequence. This makes it possible, for example, to quickly find products that might be nearing their expiration date or that need to be recalled.
