About UADshift

UADshift is a free reference tool for the appraisal industry, mapping fields between UAD 2.6 and UAD 3.6.

The data here is sourced from the UAD Redesign Appendix G-1 — Cross Reference Guide v1.4, the official spec published by the GSEs.

What you can do

  • Search by 3.6 MISMO data point, attribute, or xPath.
  • Search by 2.6 field identifier (e.g. a Form 1004 field ID).
  • See a side-by-side comparison of the legacy and redesigned definition for each field.
  • Browse the full list of fields that are new in 3.6 with no 2.6 equivalent.

Coverage

  • 1625 total fields in the UAD 3.6 spec.
  • 492 have a documented 2.6 cross-reference.
  • 1133 are new in 3.6.

UADshift is built and maintained by CodeDeck. The tool is for reference only — always check the official UAD specification for normative guidance.
