INCOSE notifies candidates of their progress toward certification by sending them emails. You may also check the status of your application, references, and exam results through the Certifications section of your Profile Home on the INCOSE website. 

We have a partner, Accredible, that will email you a link to view your certificate once you complete the certification process. When your certification expires, that will be noted on your certificate at the link Accredible sends you. 

There is a search of SEPs within the Certification section of the Profile Home on the INCOSE website. It does not contain those members who have requested to be excluded, but it is a place to find most SEPs listed.
