The extensive article “Who Manufactures Insignia TVs” details Insignia TVs. However, for those who are intrigued by the nuances of model numbers and additional product specifics, more information is available. When you navigate to Best Buy’s website to check out the TV offerings, you’ll see both the model number and the SKU (Stock Keeping Unit) associated with each product. It’s important to note that the SKU serves as an internal identifier used by Best Buy to manage inventory in its retail locations and warehouses. While the SKU has no practical value to consumers, it plays an important role for the company in ensuring accurate tracking and placement of products in its stores.

Insignia TV model number explanation

The year 2012 marked a significant evolution in TV model numbering systems. This shift was driven by the emergence of smart TVs and an industry-wide push for more standardized model identifiers. Previously, TV model numbers consisted of a combination of letters and numbers that were of minimal interest to the average consumer, primarily because TVs of the era were largely homogeneous, differing primarily in screen size and design aesthetics.

The advent of smart TV features and multiple screen resolutions necessitated a new approach to model numbering. This was done not only for the benefit of consumers, but more importantly to meet the needs of marketing teams. Updated model numbers began to include important information about TV features such as operating system and screen resolution.

For example, in 2018, Insignia TVs were available with two different operating systems, Roku TV and Fire TV. In 2024, the selection has been streamlined and is now offered exclusively with Fire TV. This evolution in model numbering allows for a clearer categorization of products, which makes it easier to track consumer preferences internally and helps customers identify the features of a particular model at a glance.

Decoding the model number of your Insignia TV, for example, NS-39DF310NA21 can give you valuable information about its specifications and features. Here is a detailed explanation of how to interpret this model number:

  • NS: This prefix stands for the Insignia brand, indicating that the product belongs to the Insignia electronics line.
  • 39: The number following the brand prefix refers to the TV screen size in inches. In this case, the TV has a 39-inch display.
  • DF: The following two characters (or one character in models after 2021) indicate the TV’s screen resolution and operating system. Two characters were originally used, but after 2021, they were simplified to one letter due to advances in TV manufacturing and technical aspects and because OS manufacturers have stopped supporting screen resolutions below 4K.
    • D stands for screen resolution, where.
      • “D” HD screen,
      • “N” is Full HD, and
      • “NO” (for example – NS-43F301NA24 for UHD resolution) or just “N” (for resolutions less than UHD, such as NS-43N301NA24) in the model number.
    • F stands for operating system, where
    • “F” stands for Fire TV (Amazon’s OS licensed to other manufacturers)

  • NA: This code indicates the original manufacturer, the OEM of the TV.
  • 21: The last two digits indicate the year the TV model was developed, in this case, 2021. Insignia TVs are typically released in Q4, and the model number may indicate the upcoming year, a strategic marketing practice designed to signify the model’s newness. Subsequent years follow a similar pattern: the last two digits of the year indicate the model year, starting with “12” for 2012 and ending with “25” for 2025.
