Is there a weight limit on priority mail boxes

Yes, there is a weight limit for Priority Mail boxes. The weight limit varies depending on the type of Priority Mail box and the destination of the package.

For Priority Mail boxes, the weight limit is as follows:

• Flat Rate Envelopes: 70 lbs (31.8 kg)
• Flat Rate Padded Envelopes: 70 lbs (31.8 kg)
• Small Flat Rate Boxes: 70 lbs (31.8 kg)
• Medium Flat Rate Boxes: 70 lbs (31.8 kg)
• Large Flat Rate Boxes: 70 lbs (31.8 kg)
• Regional Rate Boxes: 70 lbs (31.8 kg)

For Priority Mail packages that are not using a flat rate box, the weight limit is as follows:

• Priority Mail: 70 lbs (31.8 kg) for domestic shipments and 44 lbs (20 kg) for international shipments

If your package weighs more than the weight limit for the type of Priority Mail box or package you are using, you will need to use a larger box or a different shipping service. You can also consider using a shipping carrier that has a higher weight limit, such as UPS or FedEx.

It's also important to note that the weight limit for Priority Mail packages also applies to the total weight of the package, including any additional items such as packing materials, labels, and inserts.
