How to Talk to a Real Person in USPS Customer Service?

Some times we need to contact USPS as our parcel is lost or damaged. And the most effective way to contact USPS is a phone call.

1. Dial 1-800-222-1811, 1-800-275-8777 or 1-800-ASK-USPS.

2. When you hear an automated voice asking you to say the required option, say "Agent".

3. The automated voice will confirm if you really need to speak to an agent. Say "Yes" to proceed.

4. If you're calling during office hours you will be connected to a live agent. If not you will hear USPS customer service hours information and return to the main menu.

Does USPS Have a Live Chat?

No. USPS doesn't have a live chat. We suggest you contact USPS by phone call.

How to Successfully File an Insurance Claim with USPS?

Filing a claim is pretty easy, especially if you do it online, which is always the preferred method.

Here are the items you will need to file your claim, with more details below:

1. Original packaging

2. The estimate of Repair Cost

3. Evidence of Value

4. Official Claim form (when not filing online)

5. Original mailing receipt and proof of insurance, if available

We usually expect a claim to be a very long and drawn-out process. But it actually goes very smoothly and should receive a check within 1~2 weeks.

What type of mail requires a signature?

Some pieces of mail require a signature from the recipient at the time of delivery. 

1. Priority Mail Express (if requested), 

2. Certified Mail, 

3. Collect on Delivery, 

4. Insured Mail (over $500), 

5. Registered Mail, 

6. Return Receipt, 

7. Signature Confirmation

8. Adult Signature.

How to Find my Tracking Number?

1. Your post office shipping receipt. If you mail the package at a post office in person, you will receive a receipt for your parcel. 

2. Your insurance receipt. Many people buy insurance when products valued more than 50USD. Maybe you are one of them.

3. The confirmation email from, if you shipped your parcel using

4. The shipping email from your online retailer, if you buy online.

5. The peel-off portion of a USPS tracking label if you have one.

6. Flip over the orange slip you received if you missed a delivery.

How many times will USPS attempt delivery?

The USPS usually makes one or two attempts to deliver, based on the carrier's knowledge. After the attempts, the package will be held for 15 days from the initial delivery attempt and then returned to the sender.

If you're tracking the USPS on our website right now, we suggest you submit your email address, the newest shipping info will send to you when shipping status changes.

Can I pick up my mail before it is delivered?

Yes, you can pick up USPS package delivery before delivery at your address. 

You need to contact the post office to the tracking number of your package and told them you want a pickup. One day before the delivery you need to go to the USPS Delivery center and provide your id proof to get the parcel. 

However, you can try to pick up USPS parcel before delivery but there is no guarantee you will succeed. Because they are very strict some times or sometime or it's already in the despatch process.

Does USPS ship on Sunday?

USPS has delivered Express Mail (now known as Priority Express Mail) on Sundays (if you paid extra) since it started, and "Special Delivery" before that. 

Back about 2012, USPS started delivering parcels on Sundays for large mailers who negotiated contracts for Sunday delivery. Coincidentally, only Amazon has a contract with USPS, so the customer will get their parcel on a Sunday (or Holiday) will be Amazon packages. But if you placed an order on Shein, USPS delivers the order on Sunday with priority mail express.

USPS does NOT deliver other things on Sundays during the holiday season. In very rare instances, after a big enough storm that mail was missed for multiple days an executive order might come down to catch-up on Sunday, but that is very rare.

So the odds 99 to 1 that if you see a mail carrier delivering mail on Sunday that it's not just Amazon packages. 

What's the Difference Between Certified vs. Registered Mail?

Certified mail is designated as such because the sender gets proof of delivery and billing. The person who the letter is addressed to must sign for it, serving as proof it got to them okay.

Registered mail means it gets sent with the post office making a recording of it. That means as it gets sent to different locations, each office records the tracking of this letter or package.

Both these options cost a little more than regular mail, and both have different shipping times. Make sure you know what you need–either getting a signature confirmation or having the option to track where the letter goes.
