Fedwire Structured Address Linter

Lints a Fedwire or CHIPS ISO 20022 PostalAddress24 block against the November 2026 structured address mandate. On 2026-11-16 the Fedwire Funds Service and CHIPS remove the fully-unstructured postal address option in favor of a single hybrid format (Town Name and Country always required). Detects unstructured AdrLine-only addresses (banned), silent-fail duplication (AdrLine echoing structured field values; causes STP rejection without a visible error code), and classifies structure type. For the SWIFT CBPR+ cross-border equivalent see lint_cbpr_structured_address (art-241).

🔒 All inputs are processed locally in your browser. No data is transmitted. Do not enter real personal data — use synthetic or anonymised inputs only. PostalAddress24 fields are STRUCTURAL identifiers, not personal data. Do not enter real individual addresses.
Network
Fedwire and CHIPS structured-address rules are byte-identical for this lint (CHIPS aligns to Fedwire's hybrid format and the same 2026-11-16 date): one kernel, network only changes the citation in the output.
Structured Address Fields (PostalAddress24)
Structured street name only, no number.
Building or house number.
Postal/ZIP code.
City or town name. Always required for a hybrid address.
Two-letter country code. Always required.
Unstructured AdrLine Fields (banned from 16 Nov 2026)
Leave blank for FULLY_STRUCTURED. Fill to test HYBRID or UNSTRUCTURED. Silent-fail test: enter a line containing the street name above.
Violations
Execution Hash (SHA-256)

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

  
Run the AINumbers MCP tool `lint_fedwire_structured_address`. Task: Lint a Fedwire or CHIPS ISO 20022 PostalAddress24 block against the November 2026 structured-address mandate (network param selects fedwire or chips; rules verified byte-identical between the two networks at build time).
Call it with arguments: {"policy_parameters":{"network":"fedwire","street_name":"400 South Hope Street","building_number":"","post_code":"90071","town_name":"Los Angeles","country":"US","country_subdivision":"CA","address_lines":[]}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
