SIC 8711 maps directly to one 2022 NAICS industry, 541330 Engineering Services. Architecture and surveying are separate SIC industries, so use the row that matches the firm's primary professional service.
| SIC | SIC description | NAICS | NAICS description |
|---|---|---|---|
| 8711 | Engineering Services | 541330 | Engineering Services |
| 8712 | Architectural Services | 541310 | Architectural Services |
| 8713 | Surveying Services | 541360 | Geophysical Surveying and Mapping Services |
| 8713 | Surveying Services | 541370 | Surveying and Mapping (except Geophysical) Services |
These professional engineering specialties share the same four-digit SIC code. NAICS also keeps them together under 541330, so specialty targeting may require additional business attributes or keyword screening.
Professional engineering for buildings, infrastructure, transportation, site development, structural systems, and related civil projects.
Engineering services for machines, manufacturing processes, plant systems, industrial equipment, and production operations.
Professional design and engineering for electrical systems, controls, power, electronics, and related technical systems.
Engineering services focused on extraction, processing, industrial chemistry, energy systems, and related technical projects.
Includes marine engineering plus professional ship, boat, machine, and machine-tool design services listed within the SIC 8711 description.
Firms primarily engaged in architectural engineering are classified separately under SIC 8712. Surveying and photogrammetric engineering are classified under SIC 8713.
Most people searching for the engineering services SIC code are filling out a form or building a prospect list. If it is the second one, the code is the starting filter and the useful work happens after it.
In our portal, SIC 8711 narrows the business file to engineering services. From there you can layer on employee count, annual revenue, city, county, zip, area code, and contact name where available. The output is a CSV with the business name, phone number, address, SIC code, and the demographic fields you selected, ready to load into a dialer or CRM.
Common buyer combinations include CAD and engineering software vendors targeting firms by metro and employee band, professional liability brokers targeting engineering firms by state and revenue band, and technical recruiting firms targeting larger engineering employers by city, zip, and contact availability.
Engineering firms generally change hands and close less often than high-turnover categories such as restaurants or small retail. Contact names, branch offices, and phone numbers still change. Our US business data is refreshed quarterly, Canada is refreshed annually, and we estimate roughly 90% accuracy on business records.
These are the SIC 8711 engineering service records in the supplied file, broken out by jurisdiction. Every count below is available as a filtered download, and you can narrow further by city, county, zip, employee count, or revenue inside the portal.
