Most suppliers in the signage materials space offer verified contact details and business documents to build trust with buyers. 21st Century's Sig lacks verification on phone, work email, and business documents — this makes it harder for buyers to confirm the company's legitimacy or reach out confidently. Being based in India gives access to a large manufacturing base, but without verified credentials, buyers may hesitate to place large orders. The absence of verification signals a higher risk of miscommunication or non-delivery. Buyers should request additional proof, such as a company registration or a sample order, before engaging with 21st Century's Sig.
