AO

Most suppliers in Vietnam with a clear product range like cracker offer verified work emails, phone numbers, and business documents to build trust. AO has only verified their account email, which means buyers can't confirm their official contact details or business legitimacy through direct channels. The lack of phone and document verification increases the risk of communication delays or fraudulent activity. While AO offers a defined product range, the missing verification signals a lower level of transparency and trustworthiness compared to typical verified suppliers. Buyers should request additional proof before placing large orders or sharing sensitive requirements.
