Response type
Response type codes: 2009 to 2027
What the department was called to. Every response code was renumbered for 2027, and twenty were dropped outright.
51 codes changed number and nothing else. 12 changed meaning as well — the OFM revised what they cover, or moved them to another group. 28 are new. 20 were deleted and nothing maps to them, so a trend drawn through one stops at 2026.
111 codes
New number only means the code kept its meaning — remap it and your history holds. The other four are the ones worth reading.
