Self mailer usps requirements
The United States Postal Service (USPS) has specific requirements for self-mailers, which are mailpieces that do not require an envelope. Here are the key requirements:
- Size: Self-mailers must be at least 3.5 inches high and 6.125 inches long, and no larger than 12 inches high and 15 inches long.
- Weight: Self-mailers must weigh no more than 3.5 ounces.
- Paper: Self-mailers must be printed on paper that is at least 20# weight and 80 gsm.
- Folded: Self-mailers must be folded in a way that prevents them from unfolding during processing and transportation.
- Sealing: Self-mailers must be sealed in a way that prevents them from opening during processing and transportation. This can be done using glue, tape, or other adhesives.
- Addressing: Self-mailers must have a clear and legible address in the top left corner, using a font size of at least 8 points.
- Barcodes: Self-mailers must have a barcode that includes the delivery point sequence (DPS) barcode, which is used to sort and track mailpieces.
- Permit: Self-mailers must have a permit number or indicia (a postage payment method) to ensure that the mailpiece is properly postage-paid.
- Content: Self-mailers must comply with USPS content restrictions, such as not containing hazardous materials, flammable liquids, or other prohibited items.
- Design: Self-mailers must be designed to prevent them from being easily opened or tampered with during processing and transportation.
Additionally, self-mailers must meet specific requirements for:
- Flaps: Self-mailers must have flaps that are at least 1/4 inch wide and 1 inch long to prevent them from unfolding during processing.
- Tucks: Self-mailers must have tucks (small folds) that are at least 1/4 inch wide and 1 inch long to prevent them from unfolding during processing.
- Sealing edges: Self-mailers must have sealing edges that are at least 1/4 inch wide and 1 inch long to prevent them from opening during processing.
It's important to note that these requirements are subject to change, and mailers should always check with the USPS for the most up-to-date information on self-mailer requirements.
