OIG OPERATING STATUS

DUE TO A LAPSE IN GOVERNMENT FUNDING, ALL NON-EXCEPTED OIG EMPLOYEES ARE FURLOUGHED AND MUST CEASE ALL OIG WORK-RELATED ACTIVITIES.

This website will not be monitored or updated until full operations resume.
Your interest in the efficiency of Postal Service programs is important to us. Our Hotline remains operational, and you may still submit your concern and it will be reviewed.

You may also submit FOIA requests, however we cannot respond until the government reopens.
