USPS First Class Mail: A Comprehensive Guide

USPS First Class Mail is a popular choice for sending letters and lightweight packages. It's a cost-effective option, with a starting price of $0.58 for a 1-ounce letter.

The USPS offers a flat rate for First Class Mail, which means you pay the same price regardless of the destination. This can be a big advantage for frequent senders.

First Class Mail is also known for its speedy delivery, with a standard delivery time of 1-3 business days. This is because it's the most common type of mail, making it a priority for the USPS.

In addition to being fast, First Class Mail is also a secure way to send mail. The USPS takes steps to ensure that your mail arrives safely, including tracking and insurance options.

First-Class Mail is used to send lightweight packages and envelopes containing bills, invoices, tax forms, correspondence, and more. It's also used for personalized business mail, credit cards, and handwritten materials.

You can send mail through First-Class as long as the envelopes weigh no more than 3.5 oz and parcels are below 13 oz. First-Class Mail is the most common option for small-scale and new businesses due to its cost-effectiveness.

First-Class Mail is not the most prioritized mail option, it's actually prioritized over second, third, and fourth-class mail options.

Postcards are a great way to share a personal message with friends and family. Standard-sized, rectangular postcard stamps start at $0.56.

If you're sending an oversized postcard, you'll need to use a letter stamp, which starts at $0.73.

To ensure your postcard meets the first-class mail requirements, it should be at least 3.5″ x 5″ in size, but no larger than 4.25″ x 6″. Even a small difference in size can make it non-mailable.

Measuring the thickness of your postcard is also crucial. It should range between 0.007″ and 0.016″.

Letters can be sent as first-class mail, and their price is dependent on the weight.

Letters must be at least 3.5″ x 5″ in size, which is the same as the minimum size for postcards.

If your letter doesn't meet these dimensions and shape requirements, it might be charged a non-machinable surcharge.

Letters that exceed the dimensions are considered flats, or large envelopes.

First Class Mail may sound fancy, but it doesn't have the same meaning as flying first class. Its name actually comes from being considered the top tier of mailed letters.

It's not just a matter of prestige, though - First Class Mail has specific characteristics that set it apart. For example, it's typically used for smaller, lighter parcels weighing under a pound.

USPS First Class Mail is also used for items whose insured value is not very high. This makes sense, given that it's not the most secure or reliable option.
