3.8 Requirements for Confirmation Codes

This section includes requirements for CSPs that support the use of confirmation codes.

Confirmation codes are used to confirm that an applicant has access to a postal address, email address, or phone number for the purposes of future communications. Confirmation codes delivered to a postal or phone address can also be used as an identity verification option at IALs 1 and 2, as described in Sec. 4.1.6 and Sec. 4.2.6.

Confirmation codes used for these purposes SHALL include at least 6 decimal digits (or equivalent) from an approved random bit generator (see Sec. 3.2.12 of [SP800-63B]). The confirmation code may be presented as numeric or printable ASCII representation for manual entry, a secure (e.g., https) link containing a representation of the confirmation code, or a machine-readable optical label (e.g., QR code) that contains the confirmation code.

Confirmation codes SHALL be valid for at most:

Upon its use, the CSP SHALL invalidate the confirmation code.
