Find Arizona’s Lost Money and Prove the Claim
Arizona unclaimed property can include forgotten bank accounts, uncashed payroll or vendor checks, insurance proceeds, utility or security deposits, securities, customer overpayments and safe-deposit-box property.
Finding a matching name is only the beginning. This guide explains how to search more thoroughly, determine whether a result may actually belong to you, complete Arizona Form 600UP, prove identity and an old address, handle deceased-owner or business claims, understand the 35-year rule and avoid fake unclaimed-property messages.
Quick answer: Arizona uses a free search plus an evidence-based claim
Use Arizona’s official Unclaimed Property page or the state-authorized MissingMoney.com search. Search your personal or business name, verify that the holder and old address make sense, then complete the current Arizona Claim for Unclaimed Property form and submit the documentation that proves you are the rightful owner or authorized claimant.
Arizona claim facts worth knowing first
Arizona’s current Unclaimed Property homepage displays more than $2.7 billion due to owners. The useful question is not whether Arizona has unclaimed money—it does—but whether a particular listing can be connected to you with evidence.

What becomes Arizona unclaimed property?
Arizona defines unclaimed property broadly as financial assets owed to an individual or business that remain unclaimed for the applicable statutory period. Most property is intangible; safe-deposit-box contents are a major tangible exception.
The state is a custodian—not the original source of the money
Banks, insurers, employers, utilities, courts and other organizations first hold the property. When they cannot reconnect with the owner and the legal dormancy period expires, qualifying assets are reported and transferred to Arizona.
Arizona says the usual period before property becomes unclaimed is roughly one to three years, although the actual dormancy period depends on the property type.

If your name changed
Arizona states that when the claimant’s name changed after the property was reported, documentation verifying the name change must be provided. A marriage certificate, divorce decree or other legal record can help connect the reported owner name to the current claimant.
An old Arizona address can be the evidence that separates you from a same-name claimant
Arizona asks claimants to prove that they or the original owner lived or received mail at the address reported by the original holder.
Understand Arizona’s different timing rules before calling repeatedly
Received an Arizona “NOTICE: UNCLAIMED PROPERTY NOTIFICATION”?
This notice describes property the business still holds
Arizona explains that when you receive this specific 2026 notification, the Department of Revenue does not yet have the money. The business identified in the notice is still holding it and is attempting to reconnect with you before transferring it to the state.
The current notice states a September 30, 2026 deadline to contact that business.
Follow the notice in this order
Deceased-owner claims depend on the estate’s legal status
Arizona recognizes claims by heirs, beneficiaries and authorized personal representatives, but the evidence differs significantly from an ordinary original-owner claim.
Arizona may also ask for
A business claim must prove both the entity and the claimant’s authority
Arizona unclaimed property is not held forever
Arizona’s owner FAQ states that ordinary unclaimed property does not revert to the state until 35 years after it was reported. A claim can generally be filed during that period.
Claimable during the 35-year period after it is reported to Arizona.
Arizona may liquidate securities within three years of receipt, but the resulting proceeds remain available for the remainder of the 35-year period.
Contents may be sold after the applicable custody period, but proceeds can remain claimable during the remaining statutory period.
Arizona says it will never notify unclaimed-property owners by text message
Do not respond to an unclaimed-property text as if it came from ADOR
Arizona’s current Unclaimed Property page prominently warns that the Department of Revenue will never use text messages to inform owners about unclaimed property.
Verify state information by independently opening azdor.gov, using Arizona’s authorized MissingMoney search or calling the Arizona Unclaimed Property Unit.
Do not treat an unsolicited text message, postcard or fax as an official owner-location notice.
You do not need to hire a finder merely to claim property held by the state.
Arizona’s contact page specifically warns users not to include personal identification information such as SSN or address in general email questions.
Call 602-364-0380 or 1-877-492-9957 when you need to confirm whether a communication is legitimate.
