Jan 1, 2026January 2026 monthly summary for 18F/identity-idp: Focused on enhancing document authentication, improving user feedback during proofing, simplifying verification UI, and hardening external API robustness. Key features delivered include DDP TrueID as a new document authentication vendor option with AB testing and improved document type handling, along with UI cleanup that removes the state ID update link from the IPP verify info page to reduce user confusion. Major bugs fixed comprise AAMVA proofing feedback now returning AamvaCheckSkipped for jurisdiction/address resolution issues, and robustness improvements for USPS API responses plus nil-safety for Zip5 in IV verification requests. Overall impact: stronger, more reliable identity verification flows, clearer user guidance, and accelerated experimentation with vendor options, leading to reduced support friction and faster feature validation. Technologies/skills demonstrated: vendor integration with AB testing, enhanced error handling and nil safety in API requests, UI/UX simplification, and external API resilience.

Nov 1, 2024In November 2024, the identity IDP team advanced internationalization and IPP reliability to strengthen global usability and safeguard identity verification workflows. Key work focused on internationalization and In-Person Proofing UX text improvements across Spanish, French, and Chinese locales, plus updates to date formatting and translations for barcode alerts and IPP option text on error pages. The IPP test suite was stabilized and routing cleaned up to reduce surface area and drift, and a targeted warning was added to password reset emails for in-person enrollment to prevent accidental disruption of IPP steps. These efforts improve user experience for multilingual users, reduce operational risk in the IPP flow, and enhance test reliability and maintainability.
