Preparation of Envelopes by Departments
All letter-size envelopes must be shingled (overlap flaps), banded together, and include the Outgoing USPS Mail form with the mailing. If applicable bind different account numbers in separate groups.
Envelopes larger than letter size must be sealed by the department. Mail Services equipment will not seal them. Bind the sealed envelopes by account number including the Outgoing USPS Mail form. Envelope addresses should be type written in uppercase block letters with no punctuation.
For large mailings, the use of envelopes is preferred to folded paper. If you must use folded paper, use a heavier stock and DO NOT STAPLE THE PAPER TOGETHER. Tabs or tape should be placed over the open sides of the mailing.
