Hello, I’m glad to answer your question? Dear, good afternoon~ I can’t remember my username, so I can’t retrieve it through my mobile phone. I can only try one by one. If I really can’t Remember, you can only bring your ID card to the tax bureau hall to check your user name? 1. Enter the local electronic tax bureau and click Retrieve Password at the bottom of the page. 2. Enter the password retrieval interface, enter your username, mobile phone number, then enter the previously bound mobile phone number, and click Send Verification Code. 3. After clicking Send Verification Code, the page will pop up a prompt that the mobile phone verification code has been sent successfully. Click OK. 4. After clicking OK, the page returns to the password retrieval input box, enter the verification received on the phone, enter the password twice, and finally click Confirm. 5. After clicking Confirm, the page will pop up a prompt: Password reset successful, click OK.

Dear, thank you for your patience. I hope my answer can help you. Once again, I wish you success in your work, happiness in your family, and safety!
