The blue checkmark (or verified badge) is an icon displayed next to an account name to confirm it is authentic - typically awarded to public figures, brands, journalists, and organisations with a significant public presence. It was originally introduced to help users distinguish real accounts from impersonators.
The meaning has shifted in recent years. On some platforms, verified status can now be purchased as part of a subscription, which has blurred the line between “notable” and “paying subscriber”. On others it still carries editorial weight. Regardless of platform, a blue checkmark tends to increase trust and perceived credibility with audiences.
