What is First Class Mail?

First class mail is one of the services that USPS provides, and it is among the least expensive options. It offers a flat price for postage when you have to send a parcel domestically.

It delivers the package in 2-4 business days, and it remains consistent even during peak times. 

This option is useful when you want to send a card, personal correspondence, or information. It allows you to send it on the specific date you want it to reach, and it is a reliable option.

Sometimes when someone changes its address, and the mailpiece is left undeliverable, the USPS either returns it to the sender or delivers it to the correct address. 

You will have to pay extra if you need the tracking information because first class mail does not give this facility. The actual amount you have to pay for the mail depends on its weight.

It is when you are not choosing the flat rate option. You can upgrade your mail to either registered or certified mail

One can avail of the add-ons before dropping the mail in the mailbox. Each add-on has a separate fee along with it. Certified mail will give you proof of whether the mail is going to the correct address or not and provides you details on the time of delivery. 

What is Priority Mail?

Priority mail is known as the priority shipping option in the USPS. It is a quick way to send packages under 70 pounds of weight.

Your package will reach the address in 2-3 business days, and it is the same in priority mail flat rate shipping. It is the only service that guarantees its delivery time. 

You have overnight or 1-2 days delivery options available with priority mail. Due to these facilities, it is more expensive than other shipping alternatives.

If you purchase priority mail postage from the local branch of the post office, then you have to pay priority mail retail

But if you purchase postage from an online shipping service, USPS offers the priority mail commercial rate. The expensive option among the two is priority mail retail.

If they determine the shipping rate by weighing the mail, then it is known as metered mail. The bulky the package, the more you have to pay. 

You can send priority mail express packages on Sundays as well but not the regular priority mail. They include a free tracking option if your parcel has an official shipping label and barcode.

As long as you are not shipping at a flat rate, you can use your box to send the package.
