PECOS Enrollment Process and Advantages
The Internet-based PECOS can be used in lieu of the paper enrollment application.
Submitting the application via PECOS is the preferred method.
Advantages include:
- Faster application process
- Automatic selection of proper enrollment form(s)
- Tailored application process
- Fewer submission errors/omissions
This system allows you to securely review information currently on file, update and submit via the Internet.
Important: PECOS has two separate enrollment records for sole owners, the group enrollment and the individual enrollment. When submitting a change of information or revalidation verify and update (when applicable), the information on both enrollments.
