Middle name required for postal shipments to Russia?

USPS has notified Shipito that customers will need to use their middle names when sending packages to Russia. So Shipito freight forwarder asked customers sending packages to Russia to add their middle names to the name field in the Shipito account.

Russian Post only requires name, surname and address to identify the recipient. Russian Post can not violate the rules of the Universal Postal Union. And this is perfectly described on the Russian Post web-site.



Update
Shipito recognized that it was misinformed by a USPS representative. Middle name is not required.
