Z5 | Manual review
This code indicates the item requires human review before the system will allow completion or final posting.
What This Code Means
Z5 is a workflow status indicating that automated processing has routed the transaction or activity to a manual review queue. Manual review may be used when automated checks cannot confidently approve or reject the item, or when policy requires human confirmation. This status is common in scenarios involving higher-risk patterns, account changes, or exceptions where automated rules are intentionally conservative. Z5 is not a final outcome; it is a processing state. It does not automatically imply fraud or compliance violations; it indicates the system requires a human decision or confirmation before proceeding.
Where Users Usually See This Code
- Transaction details showing “manual review” or “under review”
- Internal operations dashboards for exception handling
- Processor logs indicating review queue routing
Why This Code Appears
- Automated checks produced an inconclusive risk result
- Policy requires manual review for certain thresholds or transaction types
- Identity signals or account data require confirmation
- Previous related issues increased review sensitivity
What Typically Happens Next
- The transaction remains pending or on hold
- Processing continues only after a review decision is recorded
- Final status updates may result in completion, decline, return, or reversal depending on outcome
What This Code Is Not
- It is not an approval or completion
- It is not a system outage indicator
- It is not a guarantee the item will be rejected
Troubleshooting Checklist
- □ Monitor the transaction record for status changes to a final outcome
- □ Check whether other transactions are also held, indicating broader review scope
- □ Avoid duplicating the same transaction while it remains in review
- □ If the status persists, contact official support for review status updates
Notes And Edge Cases
Manual review queues can introduce variable timing because resolution depends on staffing, queue volume, and policy. Some platforms batch manual reviews during business hours, while others run continuously. A manual review may apply to a single transaction while leaving the account otherwise operational, or it may restrict additional actions until the review completes. The code does not reveal what factors triggered review; it indicates only the processing pathway.
