Tik Tok's official blue bar is the official symbol of a certified blogger or brand, aiming to show its official identity and credibility to users. The certification process of obtaining the official small blue bar is very strict, requiring bloggers or brands to provide relevant certification materials and be audited and certified by Tik Tok authorities. These materials include identification, contracts, company registration information, etc. Tik Tok officials will verify these materials to ensure the authenticity and legitimacy of bloggers or brands, and then grant official certification to Little Blue Bar. Tik Tok Shen Yue's official blue ribbon is officially certified by Tik Tok, representing the official status and credibility.
