Can email address have a space
According to the standard rules of email addresses, a space (also known as a whitespace character) is not allowed in an email address. This is specified in RFC 5322, which defines the format of email addresses.
In particular, the "local part" of an email address (the part before the "@") is limited to the following characters:
- Uppercase and lowercase letters (A-Z, a-z)
- Digits (0-9)
- Special characters:! # $ % & ' * + - / =? ^ _ ` { | } ~
Spaces are not included in this list, so it's not possible to have a space in an email address.
However, it's worth noting that some email providers or services may allow spaces in email addresses, but this is not a standard-compliant practice. In general, it's best to avoid using spaces in email addresses to ensure compatibility with most email systems.
If you need to include a space in an email address, you can use a workaround such as replacing the space with a special character, like a hyphen (-) or an underscore (_). For example:
- [email protected] (recommended)
- john [email protected] (not recommended, as it may not work with all email systems)
Remember that it's always a good idea to follow standard email address conventions to ensure that your email address is easily readable and compatible with most email systems.
