Supported Characters in Okta Email Addresses

Consistent with Section 3 of the RFC 3696 specification published by the IETF, Okta email addresses support the following characters:

Standard English alphabet

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

a b c d e f g h i j k l m n o p q r s t u v w x y z

Special characters

! # $ % & ' * + - / = ? ^ _ ` . { | } ~

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

Except for the characters ' ` ~ shown above, no diacritical marks are supported in Okta email addresses.

Note: The period character (.) may not be used to start or end the part of an email address that precedes the @ symbol (known as the "local"part), nor can two or more periods be used consecutively. For example:

Supported

john.doe@example.com

Not supported

.john.doe@example.com

john.doe.@example.com

john..doe@example.com

Unicode characters

Unicode characters are supported in user names. There is a known issue with supporting unicode in primary or secondary emails.

Other requirements or restrictions

  • The email address must contain an @ symbol.
  • Email top-level domains (the 'com' portion of the email address) must have a minimum length of 2 characters and a maximum length of 20 characters.
  • 4-byte UTF8 characters are not supported in user names or email addresses.
