What should I do if I receive the code check SMS of Sichuan tax?

1. It says China tax. If it is not the verification code you applied for personally, someone else mistakenly entered the verification code applied for by your mobile phone number. 2. The short message service of the Inland Revenue Department is dedicated to a long list of numbers starting with 10, and the mobile phone number is never sent unless it is your administrator's number. 3. The phone number written at the time of tax registration is the mobile phone number, and now it is special for VAT, which is on the billing information. You don't need to change the phone number, you can change the number or modify it directly in the parameter settings, and you don't need to change it.
