Today’s technology allows DocuSend to electronically verify all USPS transactions.
The process starts as soon as DocuSend files are processed through the address verification/certification process (appending Intelligent Mail barcodes and a Unique ID number). Once addresses are certified, they are comingled into what we call a unique Mail Stream. A Mail Stream contains a group of addresses that make up an individual mailing. The unique Mail Stream is electronically sorted by USPS Delivery Zones, Distribution Centers and Delivery Postal Units.
All relevant information regarding the Mail Stream is uploaded to USPS verification units. This information also populates a DocuSend/USPS dashboard, which is monitored for transactions and USPS clearance of deposited mail.
Once the DocuSend Mail Stream is physically produced (printed, folded, inserted and posted), documentation unique to the Mail Stream is matched to the physical mail. The mail is transported to the USPS Verification Unit, matched against the electronic upload and released. This action clears the pending list of uploaded scheduled mailings on the pending list as well as creates a record of completion.
Verification of acceptance and clearance to distribution happens in the blink of an eye.
