USPS Tracking

The United States Postal Service (USPS) was born out of a principle that every citizen has a right to a low cost and reliable delivery service. The system now delivers 213 billion items to 156 million addresses annually.

Company Development

USPS Tracking - Copyright by USPSUSPS dates back to 1775 when Benjamin Franklin was appointed as Postmaster General and the service provided was immediately recognised as vital to the development of a vast, newly emerging nation. Since its early beginnings the business has been constantly adopting new technologies and methods of transportation to help it live up to the motto, ‘Neither snow, nor rain, nor heat, nor gloom of night stays these couriers from the swift completion of their appointed rounds.’ The early introduction of free delivery for newspapers ensured that literacy rates were the highest in the World for many years and loss making deliveries to the remotest communities ensured that knowledge was passed quickly and efficiently enabling the country to develop very rapidly. The Pony Express started in 1860, cutting days off delivery times in some areas, but lasted only 18 months before it superseded by the transcontinental telegraph line. Rural Free Delivery in 1896 and then Parcel Post in 1913 enabled the new concept of mail order shopping to take off, used by as much as 25 percent of the population in its early days.

Airmail began in 1918, originally using army planes and personnel, but this was taken over in 1920, and formed the basis for the US air industry today. The number of items being sent grew rapidly from the 1930s to the 60s and a search for more efficient systems lead to the introduction of the Zone Improvement Plan, commonly known as ZIP codes. In 2001 a business alliance was formed with FedEx Express which allowed USPS to improve its services without adding additional costs. The business remains as a standalone branch of the US Government and is self financing; competing for trade in the communication, distribution, delivery, advertising and retail markets.

The Delivery Process

USPS uses Intelligent Mail Barcodes (IMb) to label the items it carries with a unique identity in the form of a fluorescent pattern on the back and a black version on the front. This is completed automatically by machines that can read hand written or printed addresses. The collection and delivery service follows a standard spoke and hub format to connect sorting depots in ever increasing sizes. The hubs are divided into; Network Distribution Centres, Auxiliary Sort facilities, Sectional Centre Facilities and Destination Delivery Units. Distances of under 200 miles are generally covered by trucks and vans, while anything further away is transported by air. The USPS system is used by companies like UPS and FedEx where it fits in with their schedules, particularly to rural areas, which brings in additional revenue. Similarly, UPS has an agreement to deliver first Class and Priority Post for USPS across 98 US cities. The company now employs over 700,000 workers to handle the annual load of 213 billion items.

USPS Pricing

USPS Schipments - Copyright by USPSThere are a number of different mailing options with USPS with price dependant upon the service, size and weight of the item. Express Mail is used for letters, envelopes, tubes and packaged items with a two day delivery schedule including basic insurance. Priority Mail is slightly slower but cheaper; both options have a maximum weight limit of 70 pounds and length of 108 inches. First Class Mail does not set a specific delivery time period although it does not normally exceed three days. Parcel Post is described as the affordable and reliable way to send packages, but again with the same weight and size limitations of Express Mail. Media Mail is usually the cheapest option but is limited to books, manuscripts and other readable media formats.

Package Safety

There are a number of additional features that can be included in the delivery service by USPS which enhance the security of the item being sent. The services are Certified Mail, Registered Mail, Delivery Confirmation, Signature Confirmation and additional insurance cover up to a value of $1,000. These allow for the tracking of high value items and proof that the package has been posted and received in the case of disputes.

USPS Tracking Options

USPS uses a system known as CONFIRM to track items through its delivery process, which uses the IMb – Intelligent Mail Barcodes, printed on the packages, that provide a unique code for each one. The IMbs are read by a Intelligent Mail Devices (IMDs) which feed the information into a central database. The IMbs are read at each hand over along the route, either by fixed or hand held units, which provides an accurate way of determining when each stage is reached. The customer has different levels of access to the tracking data dependent upon the level of service that they purchased. If Priority Mail Express was selected then entering the label number will provide point-by-point tracking information; USPS Tracking, Certified Mail and Registered Mail will show when it was despatched for delivery. IMb technology can also be used to track incoming mail and also identify the sender. In addition, there is the ADVANCE system which provides a series of reports for companies that are sending out bulk mailings of advertising material and periodicals. This can provide useful information on the intended audience, incorrect addresses and confirmation that the service purchased was achieved successfully. This replaces manual publication tracking requests and provides a much higher level of information at a reduced cost.

By combining forces with other companies that might be seen as competitors USPS is managing to remain financially secure and independent. Despite the growing use of the internet the volume of items that are being delivered is still increasing year on year.

Should the tracking service not work, our support team and the support team of the shipping companies would gladly help you.

    I sent a first class package from Delaware with tracking # 9400109699937333058149 to an APO AE. It was mailed on 2/14/17 and reached the Chicago hub on 2/16/17. And that is the end of the tracking information on the USPS website. It is now 3/20/17, and the package has still not reached its destination! Who do I need to call to find out where the package is? Please help, if you can. Thank you.

  18. Charles House

    Why does it always seem that with United States postal service I get one day of tracking March 10th and then nothing until it arrives.Today is March 14th.It was in New Jersey March 10th.I live in Connecticut,New Haven.I have issues with theft at my Apartment Complex and it is imperative that I have a general idea when my item will arrive being as usps leaves it at the door without even knocking and if I’m not aware of it chances are it will be stolen.So once again no tracking from March 10th thru March 14th so far. Tracking # 9400111699000294259269. Please let me know if you know anything more than it’s in New Jersey.

  20. Steve Richey

    Damn it… don’t leave the packages at the front door.. DUH! Theives look for them and steal them.. I had a package delivered to my 94 year old mother and the tracking ticket says it was “left at the front door”.. You got to be dumber than a sack of hair to leave a package at the door and leave this time of year.. at ten in the morning.. just go inside the nursing home she’s in and give it to the desk gal.. There’s always someone at home and awake there.. and you left the package at the door and left..
    We pay extra for your service…. and this is what we get???!!!! Left outside.. idiots!!!!!

    I ordered something from Amazon and was told it would arrive on one day then that it would come the day before. Then I was sent an email that they had a delay and it may not come until 3 days after the original date. When I looked at the usps tracking to me it looked as though the carrier had no clue what they were doing as I was told it was out for delivery and found nothing. I was thenough looked again and saw it was sent to three different places, all relative to my area. I’m not sure if this was something with Amazon, usps or both, but I don’t think it was very reliable, nor that they are doing a good job in whatever area this applies to

    just in case my tracking number is 9300189843900226240619

    I tracked the item that was paid and sent to me and it says delivered. but when i checked the mail today all i got was just mail and no yellowish package. i even asked anyone in my house if they saw a package.

  24. Rose Sommers

    My grandson’s birthday is today, September 30th and his package went to California instead of Overland Park, Kansas!

    I am very upset that he will not receive his birthday package today. I sent it Priority Mail on September 26th.

    I’ve been tracking his package and today it shows that his birthday gift was sent to California. This is heartbreaking for me and will be disappointing for him. Shame on you USPS!

  25. Alison Reilly

    I always track my packages and often on the date of the scheduled delivery it doesnt show up until the next day. Undependable. I prefer UPS or FED EX which is typically reliable. I hate when a vendor uses USPS because there is often a problem or delay.

  38. Julie Meyer

    I received package one of two on 9/26/16 and when I wrote a letter to Amazon, they got me the tracking number for package two. It says that after Chicago, it went to Pennsylvania and is there now…I wonder why it went several hundred miles east instead of 100 miles north like package one did….tracking number I’m wondering when it will be coming around this part of the country again.

  39. Tee

    It says a note was left but there was none. Also someone is always home. I suspect it was taken to a different apartment or something.

  40. Luz Santana

    very unhappy with the USPS I paid priority mail on 09/10/16 and today 09/27/16 my package is nowhere to be found, very irresponsible . I have called various times, nobody seems to know where the package is. All I need it to get to the destination, or at least return it back to me.

  41. Cody

    I ordered something on ebay and had my OLD address in and didn’t realize until the day it shipped. Ebay still says it was delivered and at my old address they claim they never received. In tracking it says it is ‘undeliverable as addressed’ where do I go from here??

  42. Kolbey Hightower

    My tracking number is 9361269903501173309421. Just wanted to know when my package should arrive. Thanks.

  43. Mike Maloney

    My Package has been “In Transit” for month. The last movement was one (1) Week Ago, yes seven (7) days “Departed Shipping Center” in Western Nassau NY to travel less that 130 miles by land from my home. Not that the Turn Around Time (TAT) on the shipments is abysmal, but the “up to date status” is incredibly poor and from what I can tell unreliable. Exceptionally disappointing results over a month and I still do not have my packages.

  44. Derrick Burns

    Have not received my package. When I put in the tracking number it say it was delivered and left with individual. Who is this individual? It’s not me, not my neighbors, and not the apartment staff. Did you deliver it? Was it given to some guy walking down the street? I would like this problem addressed. Please contact me so I can provide the tracking number and get this resolved.

  45. Ana Rivera

    I send my product about a week and a didn’t receive

  46. Dustin

    Thanks for bringing my package all the way to its destination then sending it back, luckily it was time sensitive so thanks postal service for screwing that up

  47. Shawn

    Why did I waste$6.45 to send priority when regular mail would have delivered my letter in the same amount of time? I would love to know in what manner my letter was given priority. It was to be delivered today but it has only been sorted so won’t arrive until Monday. So infuriating!

  48. Treshonne Dearing

    I have been waiting on my wallet for a week going on two now and I can’t get to work without my wallet that’s in the package so can I get some type of assistance from you guys

  49. Rae

    My package still isn’t here eve though it says “delivered” it’s been almost 24 hrs since is was supposably delivered. I just want my package esp when it says it was delieved. Did they just mark it delivered or what? I was home all day yesterday waiting for it and nothing. No knock at my door, no package, nothing. I’ve ordered from this company many times and it’s always come from usps on time and at my door. But not this time. What’s going on? Where is my package?
