CHARLOTTE, N.C. — Over 70,000 pieces of delayed and undelivered mail were discovered at several Charlotte area post offices and a distribution center.

The U.S. Postal Service Inspector General’s Office performed an audit of post offices in Charlotte and Concord as well as a processing and distribution center in Gastonia in April. According to a report, 19,374 delayed letters and flats and 54,880 delayed packages were discovered during the audit.

“As postal employees and, especially as union advocates, we pride ourselves on delivering the mail and making sure that things are processed,” Miriam Bell, the president of the Charlotte Area Local American Postal Workers Union, said.

Bell, who represents postal workers in North Carolina’s southern region, said it is uncommon for thousands of pieces of mail to be delayed at once. She believes recent changes to how the USPS processes mail are creating backlogs.
