Valid length for Data in ISBN VB.NET Generator

ISBN Data Length

ISBN is a fixed length barcode symbology. There are 13 digits of numeric characters in an ISBN. The last digit of them is the prerequisite check digit. ISBN is publication symbology. The first three digits of data characters should be either "978" or "979".

Digits in ISBN VB.NET Generator

ISBN VB.NET Generator will automatically generate and calculate the check digit in ISBN basing on the string value you give to property Data. That is to say, using ISBN VB.NET Generator, you only have to place 12 digits of numeric characters in the string value of Data.

For example, if "978123456789" is to be encoded, there will be 13 digits on the image ("9781234567897"), the last digit ("7") is the check digit ISBN VB.NET Generator automatically generates and calculates for you.

Sample usage:

Dim isbn As OnBarcode.Barcode.Linear = New OnBarcode.Barcode.Linear

isbn.Type = OnBarcode.Barcode.BarcodeType.ISBN

isbn.Data = "978123456789"

Draw 2-digit add-on symbol in the image

According to its symbology specification and GS1 specification, a 2-digit add-on symbol could be used in ISBN beside its main barcode to supplement the data. When 2-digit add-on is needed, the type should be changed from ISBN to ISBN_2. Besides, supplement data should be given to property SupData, shown in following Sample usage.

Sample usage:

Dim isbn As OnBarcode.Barcode.Linear = New OnBarcode.Barcode.Linear

isbn.Type = OnBarcode.Barcode.BarcodeType.ISBN_2

isbn.Data = "978123456789"

isbn.SupData = "12"

Encode 5 digits in ISBN Add-on

Similarly, 5-digit add-on symbol could be used in ISBN where 2-digit add-on could be placed to encode more supplement data.

Sample usage:

Dim isbn As OnBarcode.Barcode.Linear = New OnBarcode.Barcode.Linear

isbn.Type = OnBarcode.Barcode.BarcodeType.ISBN_5

isbn.Data = "978123456789"

isbn.SupData = "12345"
