Prepaid Letters and Mailing

For those wishing to send a prepaid envelope to the addressee (for mail to be returned to you) the information below must be typed above the address and is required by USPS. The envelope will have postage applied with no date. Please keep return prepaid envelopes within a one-ounce-letter weight limit.

Bring the number of envelopes to ASU Mail Services for postage printing prior to your mailing. First Class Mail only.


Currently, USPS collects all outgoing mail once daily at 3:15 p.m. All outgoing USPS mail brought to Mail Services by 2:30 p.m. will be processed the same day. However, unusual peak periods, equipment down time, and situations beyond our control could cause your mail processing to be delayed, though this is not a common occurrence.
