How do I update my address or contact information in DEERS?

Direct answer: Update it online through ID Card Online under "My Profile," or call the DMDC/DEERS Support Office at 800-538-9552 — a physical address is required, since P.O. boxes aren't accepted.

Applies to: All TRICARE plans · All regions

Details

You can also fax an update or mail it to the DMDC Support Office (ATTN: COA, 400 Gigling Road, Seaside, CA 93955-6771). Updating your regional TRICARE contractor separately does not automatically update DEERS — you have to update DEERS directly, since DEERS is the source of truth for your eligibility.

What to do next

Confirm this with your Primary Care Manager or regional contractor before scheduling — rules can vary by region and by service.
