Permit Mail allows for the sending of 1,000 items or more simultaneously for domestic and international delivery. Customers must submit a minimum of 1,000 letters at once..

Business customers must have custom envelopes printed. The design of these envelopes requires prior approval from the regional sales managers of the Post Office.

A Permit Mail envelope includes an official Post Office permit insignia located in the upper right-hand corner, along with a designated permit number. The Post Office can identify the customer using this number. The phrase "South Africa" along with the official Post Office trademark is present on the insignia.

The use of Permit mail requires a registration number from the Post Office regional sales manager.

Rebates

Pre-sorted rebates are available when certain Post Office posting criteria are met, for example pre-sorting the mail according to postcodes.

Permit Mail must be posted with official bulk mail posting documentation, i.e. the Bulk Mail Delivery Note.

Permit Mail will not be accepted without this documentation which is available from your regional sales office or mail centre.
