How Many Engineers are Licensed in the United States
If you’re like me, you’ve often wondered how many people with engineering degrees have become professional engineers (PEs).
As of 2022, there are 931,640 PE licenses in the United States, with 494,542 licensees and 437,098 non-resident licenses, indicating multi-state licensed engineers.
According to the National Council of Examiners for Engineering and Surveying, (NCEES) there were almost one million PE licenses in all 50 states and the District of Columbia. This number is greater than the number of engineers who are licensed because many engineers hold licenses in more than one state.
The NCEES notes that there are 494,542 resident licenses in the US. A resident license is the same as a licensee – so this number is the number of people who are PEs.
The remaining 437,098 are non-resident licenses, meaning licenses held by individuals in states other than their primary state of residence.

The Significance of PE Licensure in Engineering
Professional engineering licensure is more than a mere credential — it’s a marker of proficiency and commitment within the engineering community. We’ve identified seven advantages that a PE license has on your career, credibility, and overall standing.
- Credential of Professional Competency: A PE license is widely recognized as a symbol of technical competence. It is an outward symbol that you have achieved a minimum level of education, experience, and technical knowledge in your profession.
- Legal Requirement for Public Safety: In many cases, especially in civil, structural, electrical, and mechanical engineering, a PE license is legally required to prepare, sign, seal, and submit engineering plans and drawings to a public authority for approval.
- Career Advancement: Holding a PE license often opens up advanced career opportunities. Many senior-level engineering positions and government roles require a PE license, and it is often seen as a significant advantage when it comes to promotions and leadership roles.
- Higher Salary Potential: On average, licensed engineers can expect higher salaries compared to their non-licensed counterparts. Engineers who have a PE license are generally considered to have greater expertise and often command higher compensation.
- Professional Autonomy: Licensed engineers have the autonomy to sign off on projects and take legal responsibility for their work. This autonomy also allows for the establishment of a private practice.
- Commitment to Ethics: Engineers who earn their PE license are also pledging to uphold a stringent code of ethics, emphasizing their dedication to the health, safety, and welfare of the public.
- Continued Professional Development: To maintain a PE license, engineers must fulfill continuing education requirements, which encourages lifelong learning and staying current with industry advancements.
The prevalence of PE licensure across the United States is not just a number; it’s indicative of the robust network of professionals dedicated to upholding the standards and integrity of the engineering profession.
Statistics: How Many Licensed PEs Are in the U.S.?
The landscape of licensed Professional Engineers (PEs) in the United States presents a fascinating picture of the engineering profession’s commitment to legal and ethical standards. Here’s a breakdown of the most recent data:
Current Number of Licensed PEs
As of 2022, there is a total of 931,640 PE licenses across all 50 states and the District of Columbia, according to the National Council of Examiners for Engineering and Surveying (NCEES).
- Understanding the Numbers: It’s important to note that many engineers hold licenses in multiple states. Therefore, the number of licenses (931,640) does not directly correspond to the number of individuals. Out of the total licenses, 494,542 are resident licenses, which means they represent individual licensees. The remaining 437,098 are non-resident licenses.
- Resident vs. Non-Resident Licenses: A resident license refers to a licensee’s primary registration within their home state. The non-resident licenses account for engineers who are also licensed to practice in additional states beyond their principal place of business or residence.
