A taxpayer identifier, usually an SSN. Numeric string, no dashes or non-numeric characters. Accepts the following formats:

1. A full 9-digit value ("123456789")
2. The last 4 digits of the value ("6789" or "000006789")

If you only capture the last 4 digits, you may either provide just the 4 digits ("6789") or a zero-padded value ("000006789"), and both will be treated as only the last 4 digits for matching.

An email address. Improperly formatted email addresses are rejected.

A phone number. A 10-digit numeric string, no hyphens or non-numeric characters. Do not include a country code: only USA numbers are supported.

The employee's first name.

The employee's last name.

The employee's ID from your system, if you manage unique IDs for employees and provide them to Everee when creating employee profiles.
