i have just created a ds-160 form, and opened the cgi portal with the same ds-160 number and paid the mrv fee. now when i try to retrieve ds-160 form,it says the surname and date of birth is wrong. i dont thing i have entered wrong surname and date of birth.
There is no way to change the DS160 number.
You can fill a new DS160 and take it to your interview. They will accept it.
