What Is the USPS Priority Mail Medium Flat Rate Box?

The USPS Priority Mail Medium Flat Rate Box is a popular shipping option for people and businesses alike. With this service, the United States Postal Service (USPS) allows you to ship a box of a specific size anywhere in the U.S. for a single, predetermined price, regardless of the box’s weight (up to a maximum limit) or destination. It’s designed to be simple, predictable, and convenient.

How Much Does It Cost to Ship a Medium Flat Rate Box?

As of early 2024, the standard price to ship a Priority Mail Medium Flat Rate Box is $17.10 when you purchase postage online or at a USPS retail location. Prices are subject to change, particularly during annual rate adjustments, so it’s always wise to check the latest postal rates before shipping.

Key Points About Pricing:

• Flat Rate: You pay one fee to ship anywhere in the U.S. (including Alaska, Hawaii, and U.S. territories), regardless of weight (up to 70 pounds).
• No Additional Zone Charges: Shipping from New York to San Francisco costs the same as shipping locally within a city.
• Commercial Discounts: If you use approved online postage providers or have a USPS business account, you might pay slightly less per box compared to retail prices.

Step-by-Step: How to Use a Medium Flat Rate Box

Shipping with a Medium Flat Rate Box is quick and straightforward. Here’s how you do it:

1. Get a Medium Flat Rate Box

• Pick up free boxes at your local post office.
• Order free boxes online through USPS and have them delivered to your door.

2. Pack Your Items

• Use the medium flat rate box only for items that fit comfortably inside.
• Make sure the box closes correctly and nothing sticks out.
• The maximum weight allowed is 70 pounds.

3. Secure and Seal

• Use strong packing tape to seal all seams and flaps.

4. Address the Package

• Write or print the recipient’s entire address clearly on the box.
• Add a return address in the top left corner.

5. Purchase Postage

• Buy postage labels at a post office kiosk, counter, or online via USPS.com or authorized vendors.
• Attach the label securely.

6. Ship Your Box

• Drop it off at a post office, schedule a free USPS package pickup, or leave it in your mailbox (if it fits).

Medium Flat Rate Box Sizes

USPS offers two versions:

1. Medium Flat Rate Box 1 (Top Loading)
2. Dimensions: 11 ¼” x 8 ¾” x 6”
3. Medium Flat Rate Box 2 (Side Loading)
4. Dimensions: 14” x 12” x 3 ½”

You can choose either, as the price remains the same. Pick the box shape that better suits your item(s).

Key Benefits of Medium Flat Rate Shipping

1. Predictable Pricing

• You always know the shipping cost upfront; surprises are minimized.
• Great for budgeting, especially if you run a small business or ship gifts often.

2. No Need to Weigh Each Package (under 70 lbs.)

• Toss out the scale! As long as you’re under 70 lbs. and the box closes, the price is set.

3. Nationwide Coverage

• Send packages anywhere in the U.S., APO/FPO/DPO military addresses, U.S. territories, and Freely Associated States for one rate.

4. Tracking Included

• Every shipment comes with free USPS tracking, so both senders and recipients can monitor progress online.

5. Free Package Pickup

• Schedule a home or office pickup—no extra charge.

6. Insurance Coverage

• Each box automatically includes $100 of insurance against loss or damage. For higher-value items, extra insurance is available for an additional fee.

7. Speedy Delivery

• Delivery within 1-3 business days is the USPS standard for Priority Mail, though this is an estimate, not a guarantee.

When Should You Use a Medium Flat Rate Box?

A Medium Flat Rate Box is ideal when:

• Shipping heavy items that fit in the box; the more the box weighs (up to 70 lbs.), the more value you get.
• Sending items to far locations—cross-country shipments can be much cheaper with flat rates.
• You want to simplify shipping costs.

Examples of commonly shipped items:

• Books and media materials
• Clothing and shoes
• Small electronics and gadgets
• Tools and auto parts

Challenges and Things to Know

1. Box Volume Limits

• If your items don’t comfortably fit, you may need to size up; “stuffing” the box past its seams is not allowed.

2. Not Always the Cheapest Option

• For lighter items, standard Priority Mail by weight and zone can be cheaper than the flat rate.
• Always compare flat rate and regular rates, especially for lightweight shipments.

3. Restrictions Apply

• Some items (like hazardous materials or restricted goods) can’t be shipped via Priority Mail.
• Check USPS shipping policies if in doubt.

4. International Shipping

• Medium Flat Rate is available internationally, but at a different (higher) flat rate.
• Restrictions and destination country rules will apply.

Practical Tips for Getting the Best Value

1. Pack Densely: Use every inch—fill gaps with packing material but maximize your space, especially for heavy, compact items.
2. Compare Rates: For items under 3 pounds, check regular Priority Mail or First-Class Package pricing—sometimes it’s cheaper.
3. Leverage Online Postage: Printing labels online via USPS or authorized vendors may unlock lower commercial rates for you.
4. Order in Bulk: Running a business? Order your boxes in bulk to always have them on hand—ordering is free.
5. Reuse Responsibly: Only use official Priority Mail flat rate boxes, not reused branded boxes or packaging.

Cost Tips for Shipping

• The heavier and farther you send, the more a flat rate box typically saves versus variable rates.
• For international shipments, always check the latest price, customs limits, and item restrictions for your destination.
• USPS sometimes raises rates in January—price shop at the start of the year if you ship regularly.
