Can i used a plain manila envelope for priority mail

According to the United States Postal Service (USPS), you can use a plain manila envelope for Priority Mail, but there are some requirements and limitations:

1. Size: The envelope must be at least 3.5 inches high, 6.125 inches long, and 0.007 inch thick.
2. Weight: The envelope can weigh up to 13 ounces (369 grams).
3. Addressing: You must use a clear and legible address label or write the recipient's address on the envelope in the correct format (see USPS guidelines).
4. Additional services: If you want to add services like tracking, insurance, or signature confirmation, you'll need to use a Priority Mail envelope with a special label or sticker.
5. Barcodes: The envelope must have a barcode on it, which can be printed using a USPS-approved barcode font or a label with a barcode.

If your plain manila envelope meets these requirements, you can use it for Priority Mail. However, keep in mind that using a plain envelope may not provide the same level of tracking and insurance as using a Priority Mail envelope with a special label.

To ensure your package is properly tracked and insured, you may want to consider using a Priority Mail envelope with a special label, which can be purchased at a post office or online. These envelopes have a pre-printed barcode and are designed specifically for Priority Mail service.
