Identity-Proofing Level of Assurance (LOA)

Identity-Proofing Level of Assurance (LOA) is defined by the U.S. National Institute of Standards and Technology (NIST) in Special Publication (SP) 800-63-2. Depending on the type of certificate selected, IGC Certificates include LOA3 or LOA4 identity-proofing as follows:

LOA3 identity-proofing is generally automated; however, in some cases, in-person identity-proofing may be used

LOA4 identity-proofing requires an in-person appearance before an authorized agent for identity verification

Lesser assurance credentials based on LOA1 or LOA2 identity proofing are not offered under IGC.
