What is a mail flat
A mail flat is a type of postal rate or classification used by postal services to determine the cost of shipping packages. In the United States, the United States Postal Service (USPS) uses a system called "flats" to classify and price packages that are too large to be sent as letters, but too small to be sent as parcels.
A mail flat is typically a rectangular package that is no larger than 12 inches in length, 12 inches in width, and 1/4 inch in thickness. Flats are usually sent at a flat rate, which means that the cost of shipping is the same regardless of the weight or destination of the package.
There are several types of mail flats, including:
- Flat Rate Envelope: A pre-paid envelope that can be used to send documents, such as letters, reports, and other printed materials.
- Flat Rate Box: A pre-paid box that can be used to send small packages, such as books, CDs, and other small items.
- Regional Rate Box: A box that is priced based on the distance it is being sent, rather than its weight or size.
The benefits of using a mail flat include:
- Convenience: Mail flats are easy to use and require minimal paperwork.
- Cost savings: Mail flats can be a cost-effective way to send packages, especially for small or lightweight items.
- Tracking: Mail flats are trackable, which means that the sender can track the package and receive updates on its delivery status.
However, there are also some limitations to using a mail flat, including:
- Size restrictions: Mail flats have size restrictions, which means that larger or bulkier items may not be eligible for flat rate shipping.
- Weight restrictions: Mail flats have weight restrictions, which means that heavier items may not be eligible for flat rate shipping.
- Limited services: Mail flats may not offer all of the services that are available for regular packages, such as insurance or signature confirmation.
