Linear 1D Symbols Barcode Module : UPC & EAN SymbologyUniversal Product Code Barcode (UPC) European Article Number (EAN)The The LEADTOOLS Linear 1D Barcode SDK includes the fastest and most comprehensive read and print support for all UPC and EAN symbols including the 2 and 5 digit extensions. UPC-A
UPC-A is the most widely used barcode in the United States as it is used extensively to identify consumer goods. UPC-A barcodes consist of 4 parts: number system, manufacturer code, product code and a check digit. The number system is the number to the left and outside of the bars. The manufacturer code is the group of 5 digits on the left. The product code is the group of 5 digits on the right. The check digit is the number to the right and outside of the bars. UPC-E
The UPC-E symbol is compressed version of the UPC-A symbol and is generally used anywhere a UPC-A symbol will not fit. The compression algorithm removes unneeded zeros from the underlying data structure effectively converting 10 characters into 6. EAN / UCC-13
The EAN/UCC-13 symbol is used internationally to indentify consumer goods. It is based on the UPC-A symbol with one difference. The numbering system in UPC-A can only be one digit, 0-9; whereas, the EAN-13 numbering system consists of two digits, 00-99. The numbering system in EAN-13 is basically a country code. Additionally, because EAN-13 is a superset of UPC-A, meaning EAN-13 barcode readers can also decode UPC-A symbols. EAN-13 Data Structures:JAN Codes (Japanese Numbering Authority)
JAN Codes are EAN-13 symbols that use the "49" number system. Bookland Codes
Bookland Codes are EAN-13 symbols that use the "978" number system and store book ISBN numbers without the ISBN check digit (last digit of the ISBN). For example, the ISBN for " Managing Human Resources " by Bohlander and Snell is 0-324-31463-9. To convert this to a Bookland code prepend "978" to the beginning and drop the ISBN check digit (the last digit) and dashes resulting in 978032431463. Use that number to calculate the EAN-13 check digit which is 2. The final Bookland code is 9780324314632. EAN / UCC-8The EAN/UCC-8 symbol is used internationally to identify consumer goods, but is shorter than EAN-13 symbols. Unlike UPC-E that can be expanded back into a UPC-A symbol, EAN-8 cannot be expanded into an EAN-13 symbol. Manufacturers must request separate EAN-8 and EAN-13 codes from the appropriate numbering authority. EAN / UPC Supplementary Extensions:UPC-A, UPC-E, EAN-13, and EAN-8 symbols may include a supplemental symbol to the right of the main symbol. This additional symbol is not as tall as the main symbol and will contain 2 or 5 characters of data. This supplemental data represents periodical issue number or manufacturer suggested retail pricing up to $99.99. EAN 2-Digit Supplementary Extensions:
The EAN 2 Extension represents periodical such as magazine and newspaper issue numbers. EAN 5-Digit Supplementary Extensions:
The EAN 5 extension represents the suggested retail price of books. The first digit represents the currency. The remaining 4 digits is the amount. For example "57500" indicates a suggested retail price of $75.00. Click here for a complete list of LEADTOOLS linear 1D Barcode features and supported symbols.
