Showing Your ID to Providers
When you go to the doctor, you will be asked for your uniformed service ID card when you check in. The office is allowed to and will make a copy of your ID card. You may not have to show your ID card after the first time you show it, but you should always have it just in case.
If you get care at a military hospital or clinic, you will always be required to show your ID card first.
Department of Defense (DoD) Benefits Number
The DoD Benefits Number (DBN) is an 11-digit number found on the back of the ID card that can be used to verify eligibility and file claims. This is the number your doctor's office will need to use (or you if you're filing your own claims).
You are also assigned a DoD ID number, a 10-digit number on the front of the ID card. This DoD ID number should not be used to submit claims. If the DoD ID number is used, the claim will be denied.
