Code 128 Barcode Introduction
Code 128, also named as ANSI/AIM 128, ANSI/AIM Code 128, USS Code 128, Uniform Symbology Specification Code 128, Code 128 Code Set A, Code 128 Code Set B, Code 128 Code Set C, Code 128A, Code 128B & Code 128C, is a self-checking linear barcode which encodes 128 ISO/IEC 646 characters.

Code 128 barcodes in .NET WinForms using VB.NET
Code 128 Character Set Encoding in VB.NET
Code 128 Encoding Characters in VB.NET
- All 128 Full ASCII characters defined in ISO/IEC 646
- Extended ASCII characters are also supported with Function Character (FNC4) used.
- 4 non-data function characters
- 4 code set selection characters
- 3 Start characters
- 1 Stop character
Using VB.NET barcode generator component, you need encode ASCII and extended ASCII characters only. All function characters, code set select characters, start/stop characters will
be encoded by barcode software.
Code 128 Encodable Character Set
- Code 128 A (Code Set A): 0-9, A-Z, and special characters
- Code 128 B (Code Set B): 0-9, A-Z, a-z, and special characters
- Code 128 C (Code Set C): numeric digit pairs 00-99
- Our website provides Code 128Auto function to allow automatic shifting between the above code sets
Code 128 maximum data length encoding
The Code 128 specification does not specify the maximum number of characters in a single barcode image.
However some Code 128 application standards will provide the limits. GS1-128 has limits the maximum length of Code 128 data to 48 characters.
Code 128 barcode check digit character
Code 128 barcode contains a compulsory check digit (checksum) character, which is based on module 103 (mod 103).
The Code 128 check digit will not be displayed in the Code 128 barcode text area (human readable interpretation), and it will not be returned by the barcode decoder (devices and software) also.
