At Symbol @: Copy, Type and Compare Characters
The at symbol @ is U+0040, named COMMERCIAL AT in Unicode. Email addresses use it between the local part and domain. Many social apps use it to introduce a mention. These uses do not make @ an emoji.

The same shape can hide a different character
The ordinary at sign, fullwidth at sign and small at sign have separate code points. A font may make them look similar. Pasting a screenshot of the shape into your memory is not enough to identify the character. Paste the actual text into the comparison field instead.
Unicode compatibility normalization can map the two variants to ordinary @. The tool only replaces those at-sign variants when you choose that command. It does not normalize your entire message or silently change other characters. Review the result before using it in an address or account name.
Email separator versus social mention
An email address has structure beyond its at sign. Copying @ correctly does not prove that a mailbox exists or accepts mail. The example name@example.com uses a domain reserved for examples. It is not a contact address for Emoji Bag.
The mention builder adds one leading @ to the text you enter. It does not look up an account, reserve a handle or confirm a platform rule. A social app decides whether pasted text becomes a clickable mention. Use the actual account name supplied by its owner.
Typing depends on the active keyboard layout
On many US English layouts, Shift + 2 produces @. This is not a universal shortcut. Other layouts place the character on a different key or modifier combination. A keyboard language setting can differ from the letters printed on the physical keys.
When a shortcut produces the wrong character, inspect your active input layout before changing the text. Copying the standard at sign is a practical alternative. The pasted-text checker then confirms whether your message contains U+0040 or a lookalike.
A mention preview is not a validation service
Keep spaces and punctuation only when the destination permits them. This page flags obvious differences such as multiple leading at signs, but it deliberately does not claim to validate every username rule. Display names, login names and public handles can follow different rules in the same app.
The comparison and builder run in your browser. They do not send their field contents to an application endpoint. The site still includes its usual advertising and analytics resources. Do not paste private email lists or credentials into a public tool.
