IA-12(5) Identity Proofing | Address Confirmation
Require that a Selection: registration code; notice of proofing be delivered through an out-of-band channel to verify the users address (physical or digital) of record.
Source: NIST SP 800-53 Rev 5, IA-12(5). The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open NIST SP 800-53 Rev 5 in the compliance library.
Base controls and their enhancements. Which apply follows the baseline you are assessed against (for example FedRAMP Moderate or High, or the low, moderate and high baselines of SP 800-53B). Text in square brackets is a parameter your organisation sets.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

Common gaps auditors find
- Address of record is confirmed only through the same channel used for enrollment rather than out of band
- No registration code or notice of proofing is sent to the user's address of record after proofing
