Nonprofit Organizations' Eligibility for Reduced Third-Class Postal Rates

A review of the file folders for 110 selected nonprofit organizations showed that the Postal Service followed its criteria for granting reduced third-class rates, although it was impossible to determine how many applications for reduced rates were denied by the Baltimore Service Center and subsequently approved at the Postal Headquarters. One hundred organizations, randomly selected from the 1,841 nonprofit organizations approved since 1952 and authorized to deposit third-class reduced rate mail at the Baltimore Post Office, and the 10 largest volume nonprofit organizations mailing from Baltimore during 1976, were included in this study.
