Let's go back to the core of SIC Codes and NAICS Codes.
Back in 1937 was the time when SIC codes were established. The system's foundation was very strong and was updated a lot of times until the year 1987. A new approach emerged for classification of member countries- the USA, Mexico, Canada called NAFTS, a free trade economic community. For more specific needs, SIC codes were updated all over again. Finally, in the need of the member countries, NAICS emerged in the year 1997.
The SIC system is still the most popular classification of industries as it's been active from the past 40 years. Marketing companies have been entrenched firmly by the SIC system. Which is why, email appending companies with SIC, NAICS coding are still popular! Although the NAICS system is pretty old, the classification hasn't caught on entirely. However, businesses rising above and are targeting email appending companies with NAICS coding.

However, several private organizations have continually been updating the SIC system to specific classifications, a lot more specific than NAICS code append. This, however, has changed with the ever-changing marketplaces, innovations in technologies, expert analysis of trends and so on.
