DEERS is the Defense Enrollment Eligibility Reporting System. Your DEERS registration verifies your eligibility to receive TRICARE benefits. Ineligibility in DEERS means you are ineligible for TRICARE benefits.
Failure to update DEERS with current information can result in misdirected communication, delayed enrollment, disenrollment, claims payment problems and other difficulties.
You may contact DEERS by calling (800) 538-9552, or visiting your local Military Personnel office.
Address change requests may be submitted through the nearest military base/post personnel office.
Address changes may also be made by calling the DEERS Support Office at (800) 538-9552. Note: To avoid delays, the best time to call the DEERS Support Office is 9:00 a.m. - 3:00 p.m., Pacific Time, Wednesday, Thursday or Friday.
The Central Beneficiary Services Department for the TRICARE South Region is available to take your calls from 8:00 a.m. to 7:00 p.m. ET, Monday through Friday. Our toll-free number is (800) 444-5445.
If you are currently a PRIME Beneficiary located within the South Region of the United States, you have the option of submitting your TRICARE Prime Quarterly Fee or Annual Payment directly online. This "real-time" option begins and ends with each transaction, meaning the fee/payment amount selected during the transaction WILL BE CHARGED to the card provided in real-time. This tool WILL NOT retain your card information as a payment option for use at a later time.
If you are an active duty service member, your military ID card expires every three years; active duty family members every four years; military retirees - indefinite; and military retiree family members every four years.
