National Accuracy Clearinghouse User Guide

The National Accuracy Clearinghouse (NAC) is a system that allows participating states to identify and prevent duplicate interstate Supplemental Nutrition Assistance Program (SNAP) participation.

All 50 states will be rolled out by the end of 2027. Missouri is one of the first states to go in.

Below is a list of other states currently in the NAC:

  • Illinois
  • Iowa
  • Kentucky
  • Louisiana
  • Montana
  • Pennsylvania
  • Tennessee
  • Utah

Access the NAC portal through Google Chrome.

The NAC must be reviewed for all household members during the application/recertification process before benefits are authorized. We are unable to run the NAC if we do not have the individual’s social security number. Prior to running the search, use existing processes to confirm ID & residency. Run the NAC during the interview so you can discuss the results of the search with the participant.

Access the NAC specifically for an individual who is being added to active SNAP benefits.

Do not access the NAC while processing a mid-certification review.

When a match is found, we must update the Match Record with the Initial Action taken within 10 days. This notifies the other state that we’re aware of the match and we are working the case.

Once the outcome is known and the case is completed, we must go back into the Match Record in the NAC portal and update the Final Disposition field. When that field is updated, notification is sent to the other state.

NOTE: Options for Initial Actions and Final Dispositions vary depending on whether Missouri is the initiating state or the matching state.

Common NAC Terminology:

Match: Notice is received when an individual has applied for benefits in one state and has or has had active SNAP benefits in another State.

Initiating State: Missouri has initiated the search/match while processing an application, recertification or add-a-person

Matching State: Missouri has received an incoming match from another state on an active case, either through the batch matching process, or another state initiating their own search. A special team is handling the incoming batch matches at this time.

Vulnerable Individual: A participant that must have their location protected (Safe at Home address, resident of a shelter for battered women/children, resident of a domestic violence shelter or anyone who self-identifies as fleeing domestic violence.) Do not include any information about this individual’s location in any comments/case notes or agency communications between states.

      3. Were all entries correct?
        1. If yes, all data is correct and no match records exist for your participant, make a comment in FAMIS documenting no match
        2. If no, correct any errors, run a new search and return to step 1.

      3. Enter the Initial Action (choose one):
        1. When MO is the initiating state:
          1. Notice Sent– select this option to indicate we’ve notified the participant we found a match. We have not yet verified their benefits have ended in the other state.
          2. Client Provided Requested Verification– select this if participant has already provided verification their case is closed in the other state.
        2. When MO is the matching state:

      5. Click Save Changes

Once the case is processed and authorized in the eligibility system, we must enter the Final Disposition to close the match.

NOTE: The Final Disposition cannot be entered until an Initial Action has been entered and saved in the NAC portal. The system will not let you enter them both at the same time.

    1. Enter the Final Disposition (choose one):
      1. When MO is the initiating state:
        1. Benefits Approved– we authorized benefits for the participant
          1. Enter the Benefits Start Date NOTE: This is not the date their case is approved, but the day their benefits begin. It may be the application date, or some other date if they are rejected for the month of application but approved for ongoing benefits.
        2. Benefits Denied– we rejected the application for the participant
          1. Enter the rejection date in the Final Disposition Date field
      2. When MO is the matching state:
        1. Benefits Terminated– we reviewed the match information and confirmed that the participant no longer lives in Missouri and the case is or will be closing
          1. Enter the Benefits End Date NOTE: This is NOT the date the case closed, it is the date their benefits actually end, typically the last day of a month. The benefit end date can be found on the closing notice that goes out to the participant.
        2. Benefits Unchanged– we reviewed the match information and confirmed the participant still lives in Missouri and their benefits will continue
          1. Enter the date it was determined their benefits will continue in the Final Disposition Date field
    2. Click Save Changes. Once both states enter the final disposition, the match record is closed automatically and changes can no longer be made.
