Merge by phone number

When importing contact data, you have the option to merge duplicates based on the phone number. This merge option allows you to consolidate the details of contacts that have the same phone number, preventing the creation of duplicate entries. By selecting the merge duplicates by phone number, the system compares the phone numbers of the new contacts with the existing ones. If a match is found, instead of creating a duplicate entry, the system merges the additional information into the existing contact. By merging the data based on the phone number, you can combine the additional fields with the existing record and avoid duplicate entries.

For example:

Existing List A:

Contact	Phone Number	First Name	Last Name	City
Contact 1	+447891234123	John	Smith	London
Contact 2	+447891234456	Agatha		Hyderabad

New contact upload: You have a new set of contact information to import, which includes additional fields:

Contact	Phone Number	First Name	Last Name	City
Contact 4	+447891234456	Agatha	Christie	Bangalore
Contact 3	+447891234789	Matt	Jones	Malvern

Final list after merging by phone number and mapping respective columns:

Contact	Phone Number	First Name	Last Name	City
Contact 1	+447891234123	John	Smith	London
Contact 2	+447891234456	Agatha	Christie	Bangalore
Contact 3	+447891234789	Matt	Jones	Malvern

The final list includes the following changes:

Added a new contact (Contact 3)

Updates existing contacts (Contact 2 and Contact 4 are merged)

“Christie” added to the Last Name

The city changed from “Hyderabad” to “Bangalore”
