Postal Inspector Education and Qualifications

Becoming a postal inspector is very competitive so having special knowledge or skills can help you stand out from other candidates.

Aside from general requirements like citizenship, age, criminal background and other factors, aspiring postal inspectors are required to have a bachelor’s degree. Due to the job tasks, a criminal justice or law enforcement degree can familiarize you with what your career might entail.

Certain areas of “special knowledge” can also help candidates be more competitive. These areas include:

  • Language skills
  • Postal experience
  • Specialized non-postal skills
  • Academic achievement

Postal Inspector Salary and Job Outlook

Postal inspector salaries are based on the Inspection Service Law Enforcement (ISLE) pay scale which corresponds to the General Schedule pay scale. According to the most recent special base rates for law enforcement, salaries start at $42,948 but increase as you move to different grade and step levels. You may also be eligible for locality pay and law enforcement availability pay.

According to the U.S. Bureau of Labor Statistics’ current Occupational Outlook Handbook, job growth for criminal investigators is expected to be about 10 percent through 2026, which is slightly faster than average.

Actual salaries may vary greatly based on specialization within the field, location, years of experience and a variety of other factors. National long-term projections of employment growth may not reflect local and/or short-term economic or job conditions, and do not guarantee actual job growth.
