It is one of the oldest and most widely used barcodes. The purpose of developing UPC was to develop such a shopping or buying system where salesperson does not have to manually enter the information of a product in the database. This saves time and minimizes human error unlike manual information entry. For this purpose, IBM developed UPC in order to ensure, quick, easy and reliable information encoding for the retail products.

Advantages

One of the oldest barcode types, extremely portable.

Contains only numerals; simple and easy to encode and decode.

Self-checking mechanism through checksum digit.

Limitations

Only numeric data encoding/decoding. Can’t encode characters and special characters.

Little tolerance for damage. Cannot be decoded even if slightly damaged.

Require close contact scanners to decode information.

Usage 

UPC-A is mostly used in USA, Australia, New Zealand, United Kingdom and Canada for encoding larger and simpler information.

Used mostly in retail stores and small products. UPC-E is even shorter, and used mostly for food products.
