Mailing tax return to the IRS Austin,TX address from abroad. Has anyone else experienced this?

I mailed my tax return (registered mail) from overseas  to the address: Department of the Treasury, Internal Revenue Service, Austin, TX, 73301. However, my USPS tracking info states that my return was delivered to front desk/reception/mail room Austin, TX, 78710.

 

Has anyone else experienced this? And was your return received by the IRS?
