Detecting Duplicate Contacts

When new contacts are added to your Qomon database—through imports, manual entry, or forms—Qomon automatically checks them against your existing contacts.

Based on certain criteria, Qomon will flag groups of contacts as potential duplicates. These groups appear in the Search duplicates view, where you can review and either merge them or mark them as “not duplicates.”


🔍 How are duplicates detected?

Qomon flags contacts as potential duplicates based on specific matching conditions. A group of contacts will be marked when they match any of the following criteria:

  • Last name (or marital name) and date of birth

  • Last name (or marital name) and phone number

  • Last name (or marital name) and email address

  • Last name (or marital name), first name, street, and house number

  • Last name (or marital name), street, house number, different first names, and same gender

  • Last name (or marital name), street, different house numbers, and same first name

Once flagged, these duplicates can be reviewed and merged through Qomon’s dedicated deduplication tools.
