Mail Classification

Be certain that your outgoing U.S. Mail is classified correctly (First Class, Third Class, Library Rate, etc.). If the classification is not immediately apparent, you must write it on the face of the envelope prior to the scheduled intra-campus mail pick-up. Mail not classified will be mailed out First Class. Large mailings of identical contents must be marked according to the proper classification.

Use the following links to navigate to the desired classification:

First Class Mail

Mail not exceeding 13 oz. may go First Class. It may not be opened for postal inspection and is the fastest transportation service available (other than special delivery and Priority Express Mail). Return to Top

Priority Mail

Priority mail is First Class mail weighing more than 13 ounces and, at the mailer’s option, any other mail matter (including regular First Class mail) weighing 13 ounces or less. Postal rates for Priority Mail are determined by weight and destination. Return to Top

Bulk Mail (Standard and Non-Profit Mail)

The campus Mail Service Center maintains Standard and Non-Profit Mailing Permits. Sending out printed material by Standard/Non-Profit/First Class Presort Mail can be very economical. The sending department must meet the following requirements before a Standard or Non-Profit Mailing is delivered to the Mail Service Center:

  1. Plan ahead and pre-schedule your Standard Mailing with campus Mail Services prior to printing. Be sure you understand and meet the specifications for Standard and Non-Profit Mail requirements. For information, contact x86963 or mail_services@csus.edu
  2. Material must be printed or duplicated only. (No originals or personalized material can be included.)
  3. Pieces included in a Standard Mailing must be identical in size, weight, and number of enclosures.
  4. Each Standard and Non-Profit Mailing must include a minimum of 200 pieces or 50 pounds of weight.
  5. You may also send items weighing 13 oz or less as First Class presort with a minimum of 500 pieces.
  6. Each mailing piece must have an individual address with a complete zip code.
  7. Foreign countries cannot be included in the Standard Mailing.

Important: Should your Non-Profit mailing be printed and/or prepared by an outside agency, ALL postal paperwork is required to be entered by Sacramento State Mail Services. Mailings may not be taken to the West Sacramento Business Mail Entry Unit or any other postal facility without being reviewed and entered electronically by Sacramento State Mail Services. Mailings not following these criteria will be rejected and subject to delay.

Parcel Post Mail

Fourth Class mail is Third Class mail weighing more than 16 ounces and less than 70 lbs. To determine rates, the zip code and the weight are required. Parcels should be marked "Parcel Post" or "PP." Return to Top

Bound Printed Matter (BPM)

Bound Printed Matter (BPM) is matter (typically catalogs, directories, books, and other printed material) that weighs up to 15 lbs. and meets specific eligibility standards, as follows: Consists of advertising, promotional, directory or editorial material (or any combination of these).

Priority Express Mail Service

Priority Express Mail (next day service) provides overnight delivery of letters and packages. To use Priority Express Mail, the letters and packages must be received by the Mail Service Center, properly prepared, by 3 p.m. This service comes with a postage refund provision and shipments are insured against loss or damage at no additional cost.

Priority Express Mail envelopes are provided by the campus Mail Service Center. Priority Express Mail is not delivered to all ZIP codes (check with campus Mail Services to make sure you are sending your correspondence to an area where this service is available).

Priority Express Mail should not be used on Friday or the day before a holiday, unless you are certain someone will be available the next day to receive the Priority Express Mail delivery. Return to Top

  • International Air Mail: International Air Mail may not exceed four pounds and require no customs declarations. Postage charges increase for each half ounce.
  • International Air Parcel Post: Each country has different prohibitions, restrictions and weight limits, and requires one or more customs forms.
  • International Surface Mail: Same as Air Parcel Post; requires longer delivery time, but is less costly.

Registered Mail

Registered Mail buys security. It is the safest way to send valuables through the mail system. The full value of the mailing must be declared when mailing for security and insurance purposes. Included in the registration fees is insurance protection up to $25,000. Only mail prepaid at the First Class or Priority Mail rates may be registered.

Registered mail must be securely sealed. Plain paper or cloth tape may be used, as long as it can absorb a postmark impression and adhere in such a manner as to destroy the envelope or wrapper if removed. Return receipt is available. Registered Mail is not available to all foreign countries. Call Mail Services at x86783 for information. Return to Top

Certified Mail

Certified Mail provides a traceable certification number and a return receipt, if requested. No insurance coverage is provided. Return receipts can be received three (3) different ways: hardcopy card (requested at time of mailing), electronic confirmation (requested at time of mailing – this is the least expensive option) and return receipt requested after mailing. Return to Top

Special Delivery

Special Delivery Service can be purchased on all classes of mail except Bulk Third Class. It provides for Special Delivery Service, even on Sundays and holidays, during prescribed hours which extend beyond the hours for delivery of ordinary mail. This delivery service is available to all customers served by city carriers and to other customers within a one-mile radius of the delivering Post Office.

Incoming Special Delivery does not always mean the article will be delivered by special messenger. Special Delivery may be delivered by the regular campus carrier if it is available before the carrier departs for their morning deliveries. Return to Top

Business Reply Mail

Business Reply mail is intended for use when it is likely that only a portion of the addressees will respond. Postage is paid only on the replies returned. Consult Mail Services before ordering your Business Reply envelopes. Return to Top
