Configure Confirmation Suffix Lookup
Turn this on and choose 4–10 characters for faster, safer Self Check-In lookup. This takes about 2 minutes.
This guide helps you configure how many trailing confirmation characters guests must enter. The default is 4 characters, and guests must enter the exact configured count.
Go to: Settings → Security → General Settings
Quick Reference
| Setting | What It Controls | When to Use It |
|---|---|---|
| ID Scan | Keeps last-4 lookup available in Self Check-In | Keep on if you want to use last-4 lookup |
| Quick Lookup with Confirmation Number Suffix | Allows suffix search in Self Check-In | Guests struggle with long confirmation numbers |
| Number of characters guests must enter | Sets the required suffix length from 4–10 | Use more characters when suffixes often collide |
| OHIP fallback | Recovers some reservations from an existing AVA record when the bulk list misses them | Use when Opera reservations should still be searchable by last 4 |
| Save General Settings | Saves your change | After you update the toggle |

How It Works
- This setting applies only to Self Check-In.
- ID Scan must be on to use this setting.
- The default suffix length is 4 characters.
- You can set the suffix length from 4 to 10 characters.
- Guests must enter exactly the configured number of trailing characters.
- A longer suffix reduces matches with other reservations arriving in the same window.
- If more than one reservation matches, the guest must enter the full number.
- If the unique reservation is checked in or due out, the guest must enter the full number.
- On Opera OHIP, AVA keeps paging while Opera says more results exist.
- Short pages no longer stop lookup early when Opera returns
hasMore: true. - AVA can still recover a reservation from an existing AVA record when the bulk list misses it.
- This fallback happens automatically and does not change other PMS behavior.
If ID Scan is off, this toggle is disabled and guests must use the full confirmation number.
This toggle is on by default for new properties.
Troubleshooting
Guests still have to enter the full number
What you see: Guests are prompted for the full confirmation number.
Fix:
- Check if multiple reservations share the configured suffix
- Ask the guest to enter the full confirmation number
Guests cannot find a reservation with the configured suffix
What you see: Search shows no results.
Fix:
- Confirm Quick Lookup with Confirmation Number Suffix is on
- Confirm ID Scan is on
- Confirm the guest is using the Self Check-In link
- Confirm the guest entered exactly the configured number of characters
- Ask the guest to try the full confirmation number
OHIP reservations still miss the lookup
What you see: An Opera reservation still does not appear after a last-4 search.
Fix:
- Ask the guest to try the full confirmation number.
- Refresh the Self Check-In session and try again.
- Confirm the reservation exists in Opera and is synced to AVA.
- If it still does not appear, confirm Opera shows the same confirmation number.
