Four kinds of reliable source may be used for addresses
What the document says“Mail returned to the State by the United States Postal Service with a forwarding address.”
The section adds a new subsection (vv) to section 1902 of the Social Security Act requiring the address process to draw on reliable data sources and to take the actions the Secretary specifies where an address changes. The reliable sources are mail returned by the Postal Service with a forwarding address, the National Change of Address Database, a managed care entity or prepaid health plan under contract where the address came straight from or was checked with the person, and other sources the State identifies and the Secretary approves.
What the document actually says“Mail returned to the State by the United States Postal Service with a forwarding address.”
One source is mail sent back by the post office. It must carry a forwarding address.
A national change of address list is another. A health plan under contract is a third. The state may name others if the Secretary agrees.
No action is recorded against this proposal. That is not evidence that none has been taken, and nobody has yet read it against the record. See what the tracker does not yet cover.
