Learn how to create custom contact data fields.
You can create new custom contact data fields to capture and hold additional information about your contacts.
The more useful data you can collect on your contacts, the more you can usefully segment, target and personalise your campaigns and, in turn, generate better response rates.
When you create a contact data field, it's added to all of the address books in your account. This way, all of your address books maintain the same structure.
Limits of contact data fields
The total number of data fields you can create and their limitations:
|Data field type||Maximum allowed||Limit for each data field|
There are an additional six default data fields that cannot be renamed used to store first name, last name, full name, gender, last subscribed and postcode.

Storing telephone numbers
We advise using the text data type for contact data fields storing phone numbers or prices, instead of the numeric data type.
The numeric data type removes 0 values, for example, phone numbers beginning 07xxxxxxxxx will have the first 0 removed and 9.50 will become 9.5. If you use the text data type, the data maintains 0 values as part of the string. Learn how to create custom contact data fields.
