U.S. Postal Standard Address Format Required for Automated Presort First-Class Discount Rates
Effective July 1, 1996, the U.S. Post Office enacted its Classification Reform to expand the mail volume processed by its automated mail processing equipment. This Classification Reform affects the address quality standards of all letter mail which is submitted for presorted first-class discounts. In order to receive the rate of $0.305 to as low as $0.27 a letter your mail must conform to the following standards:
2.5 oz., Zip+4
Shape: It is important that a letter-size mail piece be longer than it is tall (rectangular, not square) so that the mail doesn't tumble during processing.
Aspect Ratio: The aspect ratio for letter-size mail provides a measure tool to determine proper length to height ratio. Dividing the length by the height must yield a result between 1.3 and 2.5 (length divided by height= 1.3 to 2.5).
Polywrapping: Polywrap, poly bag and shrinkwrap material are prohibited for use on mailings submitted at automation-based rates.
Tabbing: Letter-size pieces not sealed on all four edges (folded self mailers, booklets, double postcards) must be tabbed to avoid jamming during high speeed processing in postal equipment. For type of tabbing and placement requirements, please see Exhibit 3-3.
Ink Acceptance Criteria: The paper stock used to make a mail piece must have ink absorption properties to ensure that the metered postage and waterbased barcode ink will dry without smearing.
Optical Character Read Area (OCR): All address information must be placed within a specific area for machine readability and a barcode clear zone must be provided for barcode application. Please see Exhibit 4-7 for mail piece Clear Zones and OCR Read Area.
Placement of Information
Return Address and Endorsements: The return address should be at top third and left half of mail piece. Endorsements such as "Address Correction requested" must be clearly spaced at least 1/4" below the return address. For additional endorsement placement location areas see "Move Update Requirement."
Readability Insert Shift: Window envelopes and inserts must be designed so that the entire address and a clear space of at least 1/8" appears in the window during the insert's full range of motion within the envelope.
Typography: Address information must be cleanly machine printed with adequate even spacing between characters, words, and other lines of address. Address lines cannot be skewed (slanted) more than 5 degrees. Please see Exhibit 4-15 and Exhibit 4-17
Automation Addressing: Addresses on your mail piece need to be machine-printed, with a uniform left margin. The OCR can read a combination of upper and lowercase characters. To conserve character spaces, OCR does not require punctuation.
Logo and Teaser Copy: For example of proper placement of logos and teaser copy see Exhibit 4-19 and Exhibit 4-20.
