4.2.1.2 Issued Recovery Codes

CSPs that support this option allow the subscriber to maintain one or more recovery addresses (e.g., postal, email, text message, voice). When recovery is required, a recovery code will be sent to a claimant-chosen address. The issued recovery code SHALL include at least six decimal digits (or equivalent) from an approved random bit generator, as described in Sec. 3.2.12. The issued recovery code may be presented as a numeric or a printable ASCII representation (e.g., Base64) for manual entry, a secure (e.g., https) link with a representation of the recovery code, or a machine-readable optical label (e.g., QR code) that contains the recovery code.

Issued recovery codes SHALL be valid for at most:

The verification of issued recovery codes SHALL be subject to the throttling requirements in Sec. 3.2.2.

When establishing recovery addresses other than those validated or verified as part of the identity proofing process, the address SHALL be verified. To verify an address, the CSP SHALL send a confirmation code with the same characteristics as a recovery code to the newly established recovery address. A recovery address SHALL be established only after the subscriber provides the correct confirmation code to the CSP. CSPs SHALL allow the subscriber to establish at least two recovery addresses.
