一、400电话要比一般的号码简单好记些，虽然它的组成部分是十位数，但是除去4000/6/1/7/8/9等前缀后剩下的只有6为电话数，而一般的座机号码都是7-8位数，所以从客户记忆来说，400电话更为好记，拨打的客户就有更多的潜在人群了。

A telephone, 400 more than the average number of easy to remember, although part of it is the ten digit, but remove the 4000/6/1/7/8/9 prefix left after only 6 phone number, but the general telephone number is 7-8 digits, so from the client memory, 400 phone is more easy to remember, call the customer a potential crowd more.

二、对于拨打的人群来说，400电话更容易拨打，因为对于外地的客户来说，直接拨打号码就可以了。普通的座机号码客户需要翻看每个地区不同的区号类别，选好后加上区号前缀，整个号码变成了11-12位数，拨打的客户就会越来越少。并且在客户拨打号码错误后（部门不统一），还需要重新拨打部门的分机号，十分不方便。而400电话一个统一的号码接入后，根据语音提示功能进入到每个分机上，或者直接找到人工服务，协助找到相应的处理部门，方便高效的解决客户需求，让客户更愿意接受。

Two, for the dialed people, 400 calls are more easily dialed, because for the customers in the field, the number can be dialed directly. Ordinary client numbers need to look at the different area codes in different regions. After selecting and prefixes, the whole number will turn into 11-12 digits, and the number of customers will be fewer. And after the customer dials number error (Department is not unified), also need to re dial the Department's extension number, very inconvenient. And after 400 phone calls and a unified number access, it will enter every extension according to the voice prompt function, or directly find artificial services, help find the corresponding processing department, and solve the customer's needs conveniently and efficiently, so that the customers will be more willing to accept.
