33421

Analysis

NAICS 33421 is the 2022 NAICS industry for telephone apparatus manufacturing, part of 3342 (Communications Equipment Manufacturing).

It has only one more detailed code, 334210, which covers exactly the same activities; the definition, index entries and statistics are on that page.

County Business Patterns counts 161 US establishments in this code in 2023, employing 8,893 people at an average annual payroll of $150,260 per employee (97th percentile of national industries). 35% of the establishments have fewer than five employees, which is close to the national mix.

Between 2018 and 2023 the number of establishments fell 21% and employment fell 19%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.

By establishments it ranks 3rd of the 3 codes at this level within Communications Equipment Manufacturing, with 14.1% of them.
