Troubleshooting​

Guests still have to enter the full number​

What you see: Guests are prompted for the full confirmation number.

Fix:

  1. Check if multiple reservations share the same last 4 characters
  2. Ask the guest to enter the full confirmation number

Guests cannot find a reservation with last 4 characters​

What you see: Search shows no results.

Fix:

  1. Confirm Quick Lookup with Last 4 Digits is on
  2. Confirm ID Scan is on
  3. Confirm the guest is using the Self Check-In link
  4. Ask the guest to try the full confirmation number

Last-4 toggle is disabled​

What you see: You cannot change Quick Lookup with Last 4 Digits.

Fix:

  1. Turn ID Scan on.
  2. Click Save General Settings.
  3. Reopen General Settings and try again.

Staff search behavior is unchanged​

What you see: Staff search still requires the full confirmation number.

Fix:

This is expected. Last-4 lookup applies only to Self Check-In.
