Congress has authorized DoD to require mandatory disclosure of Social Security Numbers of all beneficiaries of the Uniformed Services heath care system (32 CFR part 220, Section 220.9). Failure to disclose a SSN when enrolling or updating DEERS will result in loss of medical care benefits in Military Treatment Facilities. However, emergency health care services will be provided to the extent furnished members of the general public.
Individual Taxpayer Identification Number (ITIN): A ITIN will be used when a foreign national family member is not eligible for a SSN but is required to have a US taxpayer identification number. This number is issued by the Internal Revenue Service (IRS). The ITIN will permit continued medical eligibility in the Military Treatment Facilities (MTF)
Temporary Identification Number (TIN): A TIN is a system-generated number that will be automatically generated and assigned by the DEERS database for categories of beneficiaries who are awaiting an SSN, such as newborns and foreign spouses, or for those who do not have a SSN.
Note: A TIN cannot be used to add a record from a RAPIDS application to the DEERS database for convenience of family members who have failed to provide SSN documentation or have misplaced it. Therefore no proof of SSN, no entry will be made into DEERS and no ID card will be issued to the dependent of the military member.
A 90-day temporary ID card can be issued to reflect a TIN to beneficiaries who do not yet have a SSN or ITIN (i.e., foreign spouses) and enroll beneficiary in DEERS. If applicant has applied to the SSA but has not yet received a SSN or ITIN, another 90-day card can be issued. If after 180 days no SSN is available, then the member's Service Project Office is the only one authorized to give the ok for another 90-day card.
SSN proof - A Social Security Card, or other official government document that specifically states the number is a SSN when entering family member's SSNs in the DEERS application
