A model number is used to differentiate one product in a series from another. Model numbers are commonly used in many different types of product manufacture. Letters are sometimes used along with numbers in the coding. There is no standard format for how the letters and numbers are used; companies are free to decide how they want to use them.


A model number can indicate the features present in a product. Higher model numbers often indicate the addition of new features and improvements to a product.


Model numbers can help a consumer differentiate between two products made by the same manufacturer that look similar.


A higher model number does not always indicate that a product is better than another in the same product line. Make sure to investigate the differences among models before purchase.


The model number of a product is often featured prominently on the packaging of said product. On the physical product itself, the model number is most commonly found on the front, rear or bottom of the product.

Time Frame

A model number can be used to indicate when a product was released by the manufacturer. A higher model number often indicates a later date of manufacture.
