400 telephone is not a free call, but a shared service between the calling party and the called party, that is, the calling party bears the local telephone access fee and the called party bears all the incoming call answering fees. At present, it has been widely used in multi-industry pre-sales and after-sales service consultation.
400 telephone is mainly used as an enterprise, and the applicant needs the company main body. However, many enterprises use 400 telephones for marketing, so when users complain about harassing calls, 400 telephones account for a very large proportion.

National unique number
Use a 10 digit 400 number to bind the company's original telephones. From then on, it is only necessary to publish the only 400 number in the country, which is unified and easy to remember. When your customer dials the 400 number, you can transfer the call to the original different number of the company according to your settings. If the customer remembers the number 400, it means remembering the enterprise.
When the company needs to replace the original phone due to reasons such as moving, the 400 number does not need to be replaced, just replace the phone bound under the 400 number, and the business will never be lost.
The 400 number applied by the enterprise is the only virtual number in China, which can be unchanged for life. When the company moves (even if it moves across provinces), it only needs to change the physical phone number (landline and mobile phone) bound under the 400 number, and the old customers can still dial as usual, and none of them will be lost. It also saves you a lot of expenses for reprinting promotional materials and the trouble of notifying old customers one by one.
