+Defining URL

+
+This code system defines levels of identity assurance, based on [NIST 800-63-3](https://pages.nist.gov/800-63-3/sp800-63-3.html#52--assurance-levels).
+
+These codes may be used by Issuers of SMART Health Cards to record if/how a patient's identity was verified at the point of care. For example, if a patient showed their driver's license to verify their name and date of birth when getting a vaccination, this would correspond to `IAL1.4`.
+
+The following codes are included in this code system:
+
+|Code|Display|
+|-|-|
+|`IAL1`|Name and birth date were self-asserted.|
+|`IAL1.2`|An unspecified ID was used to verify name and birth date.|
+|`IAL1.4`|A government-issued photo ID was used to verify name and birth date.|
+|`IAL2`|Either remote or in-person identity proofing is required. IAL2 requires identifying attributes to have been verified in person or remotely using, at a minimum, the procedures given in [NIST Special Publication 800-63A].|
+|`IAL3`|In-person identity proofing is required. Identifying attributes must be verified by an authorized CSP representative through examination of physical documentation as described in [NIST Special Publication 800-63A].|
+
+For `IAL1.4`, in the US, "government-issued photo ID" may include IDs such as a US state-issued driver's license, a US nationally-issued ID like a US passport, or a foreign passport.
