The consequences of filling in the wrong phone number in one step

Does not affect. The purpose of filling in the registration phone number of the college entrance examination is that when the admission notice arrives, the school or other relevant departments can inform the relevant students to receive the admission notice through the filled mobile phone number. This is only for the convenience of receiving the notice, regardless of whether it is accepted or not. Therefore, changing the registration number of the college entrance examination will not affect the admission situation.
