what is beneficiary id

A beneficiary ID is a unique identifier used to validate eligibility for certain benefits or services. It is commonly used in the context of COVID-19 vaccination, where individuals are assigned a beneficiary ID to receive the vaccine and obtain the vaccination certificate. The beneficiary ID may also be associated with cash payment programs, particularly Social Security, to specify the basis of the beneficiarys eligibility and the type of relationship between the individual and the primary beneficiary.
