Need to update the passport number after submitting the DS-160

[Washington123 19]

Hello all,

we submitted the DS-160 for tourist visa for both of my parents. Later we noticed that the passport numbers entered on DS-160 were old passport numbers. We have already paid the visa fees but we have not scheduled the interview appointment yet. We called the UStraveldocs.com agent and they said that we can update the passport numbers on UStraveldocs.com profile as long as we have not scheduled the appointment. But I am worried because the DS_160 confirmation page as well as the visa fee receipt still shows old passport number. What should we do? Would they even let my parents inside the embassy if they notice this discrepancy ? Any suggestion would be greatly appreciated.

I had to do the same thing when applying for mine. I just emailed support@ustraveldocs.com and explained the situation to them. They emailed me back and asked for a scanned copy of my bio-page and changed it on their end. I bought a copy of the email chain with me to the interview just in case something failed on their end.
