GRAYHAVEN, Pennsylvania — A parcel cooperative has set aside six shipments after their recorded weights changed when intended recipients identified personal details about the senders. Grayhaven Parcel Cooperative has refunded two postage adjustments and asked customers not to open the packages until its insurer and scale contractor complete a review.
Clerk Mina Saye noticed the first change Friday while pricing a box mailed by a retired millworker to his adult daughter in Ohio. The parcel weighed 8 pounds, 6 ounces on the counter scale. During a routine address-verification call, the daughter asked whether the sender had used the nickname "Button" in the return line. The scale rose to 11 pounds, 2 ounces while the sealed box remained untouched.
Saye moved the box to a second scale and received the heavier reading. When another clerk read only the printed legal name, the parcel returned to its original weight. The daughter then described a blue enamel cup she expected to find inside. Both scales added 14 ounces, then settled back when the call ended.
Five more packages behaved similarly over the next day. A padded envelope became nearly a pound lighter when its recipient correctly named the song the sender played while cooking. A carton of winter clothes added 3 pounds after a college student recognized his grandmother's habit of putting cedar chips in the sleeves. Incorrect guesses did not alter either reading.
Cooperative manager Lenora Price stopped outgoing transfers Saturday and called each customer from a written script. She said clerks did not ask for passwords, account numbers or other security information. Recipients were invited to state one ordinary fact that could be confirmed by the sender. Four packages changed weight; two remained stable until the speakers used private forms of address.
All six shipments are intact, with no dampness, torn tape or shifting contents, Price said. The cooperative photographed the seals and placed the parcels on separate shelves. Their combined weight at rest matches the amount recorded at intake, but individual readings vary during calls even when the phones are in the front office, out of sight of the weighing room.
Mechanical scales can bind as temperatures change, and electronic models can drift around radio equipment or uneven floors, said Jaspreet Kelm, the technician who tested the depot's equipment Sunday. He used certified weights on three devices and found them within commercial tolerance. Kelm said no known fault would make separate scales respond to a conversation while leaving standard weights unchanged.
The changes have created modest but unresolved billing problems. Regional carriers charge by weight bands, and one package crossed two bands during its verification call. Price issued refunds rather than collect higher rates and will hand the shipments to a carrier only after written weights can be fixed. No delivery dates have been promised.
Senders have offered explanations for the contents but not for the readings. The retired millworker said his box held canned peaches, two books and the blue cup his daughter mentioned. With her permission, he repeated its chipped handle and the summer they bought it. The box gained another 7 ounces while he spoke, though nothing inside could be heard moving.
One parcel could not be verified. Its sender, Agnes Dorr, died Friday evening after leaving a small package for a former neighbor whose current address was incomplete. The box weighed 2 pounds at intake and 2 pounds on Sunday until retired clerk Rhea Moss recognized Dorr's handwriting and called her "Aggie," as she had during their years at the hosiery plant. The pointer dropped below the scale's zero mark without the platform rising.
Price removed that parcel from the scale and placed it on the lowest shelf, where it rests normally and does not feel empty when lifted. Its handwritten label gives only a first name and the former address of a house demolished in 1998. By Sunday evening, the shelf beneath the box had bowed upward by about half an inch.
