Get a 400 Phone Number in China's Shared Cost Network
China's 400 numbers are shared-cost service lines regulated by the Ministry of Industry and Information Technology, allowing callers to share the call cost with the receiving business. Unlike toll-free 800 numbers, 400 numbers work across both landlines and mobile phones, making them far more accessible to China's predominantly mobile-first population. For businesses operating in or entering the Chinese market, a 400 number signals legitimacy and permanence — two qualities that Chinese consumers and B2B partners actively look for before engaging with a company. Industries such as e-commerce, financial services, education technology, logistics, and customer support centers rely heavily on 400 numbers as their primary inbound contact channel. Having a 400 number removes the barrier of long-distance call charges for customers dialing from any province, encouraging more inquiries and improving conversion rates. It also enables businesses to route calls intelligently across regional offices or call centers without exposing internal direct lines, giving operations a professional, scalable structure from day one.
