There are 2 types of bar codes: 1D and 2D

* 1D barcodes called 1-dimensional (one-dimensional linear) include the following types of bar codes

• EAN-13
• EAN-8
• Code 39
• Code 128
• Interleaved 2 of 5 (ITF)
• Codabar
• Postnet

* 2D barcode called 2D (two-dimensional) barcode types including
• PDF-417
• MaxiCode
• Data Matrix
• Code 16K
1. UPC-A

- Used first in supermarkets in the United States
- Used primarily for sale
- Most popular in north and South America
- Use only numeric data
- Fixed barcode length (mean length bar code will not change when the data is more or less)

2. UPC - E

- The first child of the UPC - A
- Less used
- Use only numeric data

- Like the UPC - A is commonly used in Europe in 1976
- Used in cosmetics
- Popular for retail product code
- Like just data UPC number

- Requires exactly 12 digits plus 1 check digit mandatory
- Each country uses a standard format for the EAN - 13
* Format EAN - 13
