Quick Answer
How do you import multiple phone numbers for one contact?
Add an Additional Phones column to your CSV and place multiple phone numbers in the same cell separated by commas, slashes, or semicolons. Upload the CSV through Contacts → Import, map that column to Additional Phones, review the import settings, and submit the import.
What Additional Phones Is For
You may have contacts with more than one phone number, but storing each number on a separate contact can create duplicate records and make follow-up activity harder to manage.
The Additional Phones field allows you to store more than one number on the same contact record, including mobile, office, and alternate phone numbers.
This keeps multiple contact points together while maintaining one clean CRM record for the same person.
BizStackPro also supports importing and exporting these additional phone numbers through CSV files so larger contact databases can be updated or moved more efficiently.
Keep multiple numbers on one contact
Additional Phones can help prevent contact information from becoming scattered across multiple records when one person has more than one phone number.

Step-by-Step: Import and Export Multiple Phone Numbers
Follow these steps to prepare additional phone numbers for import, map them correctly, and export them again when needed.
Prepare the Additional Phones Column
Prepare your CSV with a column for Additional Phones.
Place all additional phone numbers belonging to the same contact inside one cell.
Separate Multiple Phone Numbers
When a contact has more than one additional phone number, separate the values using one of the supported separators:
- Commas (,)
- Slashes (/)
- Semicolons (;)
Upload the CSV
Go to Contacts, open the Import flow, and upload your prepared CSV file.
Map the Additional Phones Field
During field mapping, map the CSV column containing the alternate phone numbers to the system field Additional Phones.
Review the Import Settings
Review your contact-matching, duplicate, tag, and other import settings before completing the import.
When the settings are correct, click Submit.
Review the Primary Phone
If the primary Phone field is blank, the first valid number in Additional Phones is typically used as the contact's primary phone number.
Export Additional Phone Numbers
When exporting contacts, include the phone field in the selected export columns, such as when exporting from a Smart List.
Additional phone numbers are typically included in a separate CSV column, often labeled Additional Phones. Multiple numbers generally appear in one cell as a comma-separated list.
