Should I resend form 3520 before 4/15? USPS might lost my certified mail

[user17741970903]

I mailed my Form 3520 to the IRS PO Box  using certified mail, but the tracking still shows “moving through the network” with no delivery confirmation. I’ve already submitted a missing mail request with USPS. If delivery can’t be confirmed, should I resend the Form 3520 before April 15 with a cover letter marked “possible Duplicate Filing” and send it via FedEx to a physical address instead of the PO Box?

Thanks!

The instructions for Form 3520 state expressly to send it to this PO Box - don't use another address:

Send Form 3520 to the following address.

Internal Revenue Service Center
P.O. Box 409101
Ogden, UT 84409

To ask them directly, you can start by calling the IRS international tax issues line: 267-941-1000

A duplicate filing of Form 3520 may accrue an automatic civil penalty onto your account, which could drastically slow down processing of the original return. This might be a question for an attorney. 

If you have the certified mail receipt, you should be able to furnish this as proof of timely filing if the form is truly lost. Make a copy of your missing mail request, and keep that with your records as well. I thought everything I sent last year by certified USPS was lost or even tossed away; I didn't get a single confirmation of delivery, so I wouldn't be so quick to assume it's truly lost in the mail. All the certified mail I sent was delivered, eventually. 

Your mileage may vary. 

To see if the form has posted to your account, you can also send Form 4506-T Request for Transcript and put "3520" on Line 6.
