Usps bulk mail rules

The United States Postal Service (USPS) has specific rules and regulations for bulk mail, which is defined as mail that is sent in large quantities, typically in excess of 200 pieces or 50 pounds. Here are some key rules to keep in mind:

1. Mailing Lists: Bulk mailers must maintain accurate and up-to-date mailing lists. The USPS recommends using a mailing list service or software to ensure accuracy and compliance.
2. Addressing: Bulk mail must be addressed correctly, with the recipient's name and address printed in the correct format. The USPS recommends using a font size of at least 6 points and a font style that is easy to read.
3. Barcodes: Bulk mailers must use a barcode on each piece of mail to facilitate sorting and tracking. The USPS recommends using a 4-state barcode, which is a 4-digit code that identifies the mailpiece.
4. Weight and Size: Bulk mail must meet specific weight and size requirements. For example, First-Class Mail must weigh no more than 3.5 ounces, while Standard Mail must weigh no more than 16 ounces.
5. Mailpiece Design: Bulk mailers must design their mailpieces to meet specific requirements, including:
   • Minimum size: 3.5 inches wide x 6.125 inches long
   • Maximum size: 12 inches wide x 15 inches long
   • Thickness: no more than 0.25 inches
6. Paper Quality: Bulk mailers must use paper that meets specific quality standards, including:
   • Weight: at least 20 lb. for First-Class Mail, at least 18 lb. for Standard Mail
   • Finish: smooth, even finish
7. Permit Requirements: Bulk mailers must obtain a permit from the USPS to mail their bulk mail. The permit must be affixed to the mailpiece and include the permit number.
8. Postage: Bulk mailers must pay postage according to the USPS's postage rates. The rates vary depending on the type of mail, weight, and distance.
9. Mailing Dates: Bulk mailers must mail their mailpieces on or before the designated mailing date to ensure timely delivery.
10. Compliance: Bulk mailers must comply with all USPS regulations and guidelines, including those related to mailpiece design, addressing, and postage.

Some additional tips to keep in mind:

• Use the correct mail class: Use the correct mail class (First-Class Mail, Standard Mail, etc.) to ensure accurate pricing and delivery.
• Keep records: Keep accurate records of your bulk mailings, including the number of pieces mailed, postage paid, and mailing dates.
• Consult the USPS: If you have questions or concerns about bulk mail regulations, consult the USPS's website or contact your local post office for guidance.

Remember, compliance with USPS regulations is essential to ensure timely and cost-effective delivery of your bulk mail.
