REQUIREMENTS TO QUALIFY A MAILING FOR DISCOUNT SERVICE

  • Mailing must be a minimum of 200 pieces.
  • Mailing must have 128 permit indicia in upper right hand corner of the address side of the mail piece.
  • Mail must be in zip code order from lowest to highest zip code.  Any zip code containing 150 pieces or more must be banded together and have the exact number of pieces attached to the bundle.  No other separation is needed.
  • A report must accompany the mailing showing the number of pieces in each zip code and conclude with the total number of pieces in the mailing.
  • Mailing cannot be offering anything for sale, such as tickets or fees.
  • Not to be used for time sensitive mailing, a maximum of 3 days is requested for processing at the Winthrop Post Office, and the US Postal service allows itself from 2-9 days for delivery. In most cases the mailing is delivered in 2-4 days, but standard mail receives the lowest handling priority.
  • A Service endorsement must appear on each piece.  Refer to Service Endorsement Reference Chart for examples.  The most commonly used at Winthrop is forwarding service requested or address service requested. Please refer to “Service Endorsement Reference Chart” offered on this web site for further information.

MACHINABLE STANDARD

This is the preferred and easiest way to prepare your mailing for standard mail.
To meet the requirement for machinable mail, your mailing must be either a post card, in a sealed envelope, or if folded paper tabs at each end of the mail piece sealing all loose sheets together.

Non-Machinable Mail

Flats include mail that is oversized for letter mail. Flats receiving discount rate must now be addressed in portrait mode as opposed to the traditional landscape mode.  This is new as of June 2009. Flats must be placed in white mail tubs obtained from our office. Each Zip Code must be rubber banded together, unless one zip code fills the bucket. A report must accompany the mailing listing the number of pieces in each zip code. 
All the requirements listed for machinable mail, can be applied to flat mail pieces.
