Did You Retire, Move or Have a Baby?

Whenever you experience a life changing event, such as marriage, divorce, birth, adoption or a sponsor status change, it is essential that you update your information in the Defense Enrollment Eligibility Reporting System (DEERS) so you don’t delay or lose TRICARE coverage.

You can verify and update DEERS in one of the following ways:
