1. Confirm whether the submission platform you are using requires a specific phone format. Some platforms may require you to provide an international area code or phone number in a specific format.
2. Confirm whether your phone number conforms to the phone number format of your country or region. If you are in China, your phone number should be 1 1 digit, and the first digit cannot be 0.
Please make sure that your phone number is spelled and entered correctly. Even spelling or typing mistakes may lead to your work being rejected.
Make sure your phone number is clear and easy to read. If your phone number is difficult to read or identify, it may cause the platform to be unable to contact you.
In a word, it is very important to make sure that your submission telephone format is correct. If you are not sure whether your phone format is correct, please check the guide of the submission platform you are using or contact the support team of that platform for help.
