User Formatting Rules

email_address

• • Our system validates top-level domain (TLD) extension of a member’s email address. This is to ensure that only valid TLDs are used (i.e. .com, .net, .gov, .edu, etc.). .testest is not a valid TLD and will cause the User Create/User Update call to error.

  • There can only be one “@” symbol. The characters before the “@” symbol in the username must be in the set of alphanumeric values or “. _ % + -“; all other characters are disallowed. The characters after the “@” in the mail server must contain only alphanumeric values or “_ -“; all other characters are disallowed. A “.” must separate the mail server and top-level domain. Lastly the top-level domain must only contain 2-6 alphabetic characters. None of the email validation rules are case sensitive.
  • Allowed values
    • For username: alphanumeric or . _ % + –
    • For mail server: alphanumeric or –
    • or top level domain: alphabetic characters only
