A USPS worker has shared the items you shouldn’t post with your letters as “the machine will rip them out.” Hint: It’s almost everything.
The anonymous worker took to TikTok under the name @secretsofusps to hand out the advice in a video with over 5 million views.
Delivery Barcode Sorter (DBCS) machines at USPS facilities read the barcodes on each letter and sort them. Each machine can sort around 36,000 pieces of mail in an hour. The machine normally takes two workers—one to load the input letters and another to gather the mail after.
This advice comes straight from an employee who said they can work over 10 hours on the machine a day.
