Can i ship registered mail in a flat rate box

Yes, you can ship registered mail in a flat rate box, but there are some limitations and considerations to keep in mind:

  1. Flat Rate Box Size: The flat rate box must be the correct size for the weight and dimensions of the item you're shipping. You can use the USPS Flat Rate Box Calculator to determine the correct box size.
  2. Weight Limit: Flat Rate Boxes have a weight limit, which varies depending on the box size. For example, the Small Flat Rate Box has a weight limit of 70 lbs, while the Large Flat Rate Box has a weight limit of 130 lbs.
  3. Registered Mail Requirements: Registered Mail requires a unique tracking number and a signature upon delivery. Flat Rate Boxes do not have a built-in tracking system, so you'll need to use a separate tracking label or sticker to comply with Registered Mail requirements.
  4. Additional Fees: You may need to pay additional fees for Registered Mail, such as the registration fee, insurance, and tracking fees. These fees will be added to the cost of the flat rate box.
  5. Insurance Limitations: Flat Rate Boxes have insurance limitations, which may not cover the full value of the item you're shipping. You may need to purchase additional insurance coverage to ensure the item is fully insured.

To ship registered mail in a flat rate box, follow these steps:

  1. Choose the correct flat rate box size for your item.
  2. Determine the weight and dimensions of your item to ensure it fits within the flat rate box size and weight limit.
  3. Purchase a separate tracking label or sticker to comply with Registered Mail requirements.
  4. Attach the tracking label or sticker to the outside of the flat rate box.
  5. Complete the Registered Mail form (PS Form 3800) and attach it to the outside of the flat rate box.
  6. Pay the registration fee, insurance, and tracking fees (if applicable).
  7. Hand the flat rate box over to the USPS carrier or mail it at a post office.

Remember to check with your local post office for specific requirements and fees associated with shipping registered mail in a flat rate box.
