First-Class Package Service

The first class package service USPS is a service that USPS provides customers included in the other typical services like priority mail, shipping services, and retail stores. One of the most popular mail categories is actually the first class mail service. As one of USPS’s best services, many customers use this type of mail sending to ship their packages.

What is a First Class Package?

USPS First Class Package is the most used service on the USPS. Customers choose top-notch mail because it’s not only the best way to send it right away, but it’s also very cheap. Customers can use this mail class to send content such as the following:

  • Standard postcard
  • letter
  • Large envelope
  • Small package (weight should not exceed 15.99 ounces)

If the first-class package weighs more than 15.99 ounces, the remaining option is to ship the box using the “First Class Mail” category.

First-class parcel services cannot guarantee delivery time, but in general, first-class mail (letters, large envelopes, standard postcards, small packages, etc.) will take a few days to reach your address. It also only takes a few business days to reach the destination.

The main features of the first class package service USPS:

  • The mail-in in this category usually has a delivery time of 1-3 business days.
  • With this service, customers can get 3.5 ounces of commercial price letters and postcards for free.
  • As already mentioned, this type of mail is a budget option and is recognized as the best-priced service for mail under 13 ounces.
  • The mail-in in this category also includes insurance. However, there are restrictions on the insurance standards for this mail category item. In the event of loss or damage to the carriage of first-class mail, the maximum insurance amount for the item only is $ 5,000.
  • Similarly, this category’s mail can be checked for delivery combined with many other USPS additional services (signature verification).

Limiting factors:

You will actually not be able to send mail in this category as you wish. You have to follow some restrictions. The restrictions are as follows:

You can send up to 3.5 ounces of first-class mail. For large envelopes or parcels, the maximum weight used by this category of mail is 13 ounces.

To send mail using this service, you need to make sure that the postcard and envelope or flat envelope are rectangular. If this is not the case, additional costs may be incurred. These different size limits depend on the type of item you are shipping.

First-class delivery must comply with general USPS restrictions. These are specific general rules and standards for shipping items. Do not restrict, ban, or prohibit the use of dangerous goods for anything you want to carry. This list also includes smokeless tobacco and tobacco.

First-class mail prices are calculated based on mail size, shape, and weight. The details are as follows.

For non-machinable envelopes, it’s more like a square envelope, a square envelope, a vertical envelope, a rigid envelope, etc., rather than a message of regular shape. It also has hooks, buttons, and cords that must be manually removed. Even if you weigh less than an ounce, you may need to pay for a non-processable supplement.

Larger envelopes cost more when the envelope exceeds the maximum length, height, or width setting limit. You may have to pay extra based on the next highest product category.

If a large flat bag is large and rigid, non-rectangular, or uneven in thickness, the package price will be charged.

How does first-class mail work?

Do you know how the “First Mail” category works? The first thing to do is to seal the item and then provide your address. Next, you need to check the package size. Due to the USPS’s size limit, you must check if the package meets the specified limit before sending the box using this service.

How long does a first-class mail take?

First-class mail delivery time does not exceed 1-3 business days. This is a fast and cheap way to send lightweight packages. It is suitable for business and personal shipping. You can send tickets, brochures, lightweight items, and more to ensure that your packages arrive within first-class shipping times. However, you can see the delivery time of this message on the map below.

Why the maximum post office weight is different from the shipping software

If you look around some of the signs alongside the post office, you may have noticed a discrepancy with the maximum weight allowed in the first class package.

At retail rates (paid at the post office), the maximum weight of a first-class package is 13 ounces. The maximum value is increased to 15,999 ounces only if you purchase postage online using the shipping software.

For many shipments over 13 ounces and under $1, this roughly 3-ounce threshold can be the difference between delivery at first-class package rates and priority email payments. In some cases, sending a first-class package can save you a few dollars.

So if you actually ship a large number of boxes, you can save a few dollars in the long run. This is the main reason why you should always buy your postage online using your shipping software instead of paying retail at the post office.
