Mississippi claimants provide a copy of photo ID and their Social Security card or another formal document showing the SSN. Ownership is usually confirmed by address or SSN, and old bills, tax returns or credit reports can prove a past address.
How to file: Search by last name on the Treasury's unclaimed money search and file a claim online.
Proof required: Individuals: copy of photo ID (driver's license, passport, military ID or other official card); copy of SSN card or a formal document showing the SSN (e.g., top of a tax return); name-change documents if applicable; proof of the reported address where SSN does not verify (old bills, tax returns, school records, credit reports).

For a deceased owner, Mississippi wants the death certificate, the filed will if any, or else an obituary or funeral program listing all heirs (or a notarized Affidavit of Death from each heir). If the estate is open the Treasury pays the estate through the executor; if closed, each legal heir files a separate claim for a share.
Documents: Claimant photo ID and SSN; death certificate of the owner (and of any deceased heir); the owner's filed will, or if none an obituary or funeral program listing all heirs, or if none a notarized Affidavit of Death from each claiming heir; state whether the estate is open (paid to the estate c/o executor) or closed (split among legal heirs, each filing a separate claim).
Whether an estate must be opened is a legal question for a qualified attorney in that state.
