Description and formatting guidelines


First Name


We accept first name and first name initial, with or without accents. Initials can be provided with or without a period.


Last Name


We accept full last names with or without accents.




We accept email addresses in up to 3 separate columns. Only one email can go in each cell. US and international formats are accepted.



Phone numbers must include a country code to be used for matching. For example, the number +1 must precede a phone number in the United States.

Important: Always include the country code as part of your customers' phone numbers, even if all of your data is from the same country. The number must also include the "+" plus sign.

USA/CA example:
+1 844 412 4653

AU example:
+61 433 727 666

NZ example:
+64 3 345 6789
