How Mail Forwarding Works

How Mail Forwarding Works

Your Own US Mailing Address

If you would like to receive regular mail, such as letters and magazines, in addition to packages, you can sign up for our PREMIUM (Package & Mail) plan and receive any type of mail correspondence. Your account becomes a convenient virtual mailbox!

Shipment Service

We’ll notify you via email when we receive a mail item on your behalf. You can log in to your account and request shipment at any point in time. You can send us a shipment request from your account at your convenience. To transport your mail items to most countries we offer international shipping via UPS, ePacket, DHL and a few other carriers. A consolidated shipment with packages is also possible.

Service Options for Your Mail Items

Besides our shipment service, we provide scan, discard and shred services. As for scan service, we scan the document and upload the scanned file (PDF) to your secure OPAS account. Discard and shred services are for free of charge. Click on the link below for more details on the service fees.
