The United States Postal Service (USPS) provides mail services in the United States. In addition to delivering mail to addresses across the country, the USPS also provides customised business solutions and priority services for customers. The agency offers both online and in-person service through thousands of Post Office locations.

USPS – Live Tracking, Track and Trace Service

All mail collected by the USPS are sorted through over 250 Processing and Distribution Centers located across the United States. Individual centres are responsible for sorting mail in a given region, typically within a radius of about 320 kilometres or 200 miles. Each centre is connected with the USPS’s national network. Mail is typically sorted using an automated system, although physical inspection and sorting may be needed when an address cannot be identified by the system. All mail is printed with a bar code that is used to determine the destination as the item moves through the USPS system.

USPS Tracking here provides the status of parcels and other mail items with a label or receipt number. Items shipped with Priority Mail Express will include point-by-point tracking details, while mail and parcels sent with other services will only show when an item went out for delivery. Services with label numbers include Certified Mail, Collect on Delivery, Global Express Guaranteed, Priority Mail Express International, Priority Mail Express, Priority Mail International, Priority Mail, Registered Mail, Signature Confirmation and USPS Tracking.

USPS Tracking may be purchased online or at a Post Office, depending on the mail class that is selected. USPS Tracking provides additional details that may not be offered with label or receipt numbers alone, for example, when sending Certified Mail or Registered Mail. In these cases, basic information about when an item went out for delivery will be provided rather than step-by-step information as the item travels through the USPS network. USPS Tracking is provided at no charge for Priority Mail, Standard Post, Parcel Select, First Class Package Service and First Class Mail parcels. Charges from $0.23 when paid online and from $1.05 for other types of mail sent with the USPS. International mailing classes with tracking ability include Express, Express Guaranteed and Priority. Tracking is not available for Priority Mail International Flat Rate Envelopes or Priority Mail International Small Flat Rate Boxes.

History of the USPS

The first independent postal services in the United States were formed in the North American colonies of Massachusetts and Virginia. The first centralised postal service was created in 1691 with the North American Postal Service, although the USPS traces its roots to 1775 when the first postmaster general was appointed and the United States Post Office was created.

The Post Office Department was created in 1792. Originally focused on deliveries in cities, parcel post service between the United States and other countries was introduced in 1887 beginning with Canada. By 1896, postal service delivery expanded into rural areas and the first airmail service began in 1918. The U.S. Post Office was reorganised in 1970 with the introduction of the Postal Reorganization Act. The Post Office Department was replaced with an independent government agency, the United States Postal Service. The USPS began operations on July 1, 1971.

About the USPS

The United States Postal Service delivers to nearly 153 million addresses across the country. Approximately 40 per cent of the world’s mail volume is handled by the USPS, which processed 158.4 billion pieces of mail in 2013. The agency also manages more than 31,000 retail offices and a fleet of over 211,000 vehicles. Each year, USPS mail carriers and truck drivers drive approximately 1.2 billion miles. The USPS receives no tax dollars for its operations and is not a government-owned agency. Rather, the USPS acts as a quasi-government agency with the exclusive legal right to deliver first-class and third-class mail. It also has special privileges afforded to government agencies, including sovereign immunity, eminent domain powers and powers to negotiate international postal treaties.

According to the Mailing Industry Job Study, 2012, more than 8.4 million jobs and over $1.3 trillion in revenue is attributed to the mailing industry in the United States. The USPS plays an important role in supporting this industry. In 2013, the USPS’s revenue was $67.3 billion and employed more than half a million people. Revenue from First Class mail alone was $28.2 billion, while advertising mail accounted for $16.9 billion. The USPS’s shipping and packaging services contributed $12.5 billion to the agency’s revenues in 2013. If the USPS was a private sector company, it would have ranked 45th in the 2013 Fortune 500 ranking. In the 2013 Global Fortune 500 list, the USPS would have held the 140th position.

The USPS is governed by the Board of Governors of the United States Postal Service, which sets policy, procedure and postal rates. Nine of the board’s members are appointed by the President of the United States and confirmed by the United States Senate. These nine members select the U.S. Postmaster General, who serves as the tenth board member. The Postmaster General is responsible for overseeing the day-to-day operations of the USPS and acts as the Chief Executive Officer. The ten-member board also nominates a Deputy Postmaster General to act as the Chief Operating Officer and the eleventh member of the board. The Postal Regulatory Commission is responsible for overseeing postal rates and related concerns. The Commission can approve and reject USPS proposals. Appointees to the Commission are selected by the U.S. President and confirmed by the United States Senate.

The USPS publishes the Domestic Mail Manual, which outlines standards for letters, parcels, and other mail articles shipped within the United States. All articles of mail must comply with these standards when shipped within the country. Standards include maximum and minimum dimensions and weight, proper sealing and closure, how to use markings, restrictions on hazardous and restricted materials, and other guidelines. The delivery address must be left-justified and located more or less in the centre of the item’s largest side, while the return address must be places on the upper left corner. The USPS also publishes the International Mail Manual with similar standards for international services, including restrictions and conditions for sending items to specific countries.

USPS Prices & Online Shop

The price of sending items with the USPS depends on the type of mailing, the weight and dimensions of the item, and other applicable surcharges. The USPS does not deliver packages that are over 32 kilograms or 70 pounds, or with combined dimensions of greater than 270 centimetres or 108 inches (330 centimetres or 130 inches for parcels). Senders must generally use another service when sending a larger item, for example FedEx or UPS.

    This tracking says delivered June 17th but my package still hasn’t arrived 3 days later. I am home all the time so could not possibly have missed it. Why does it say delivered??

    Please could you check that the tracking details are correct and if the package is actually on its way to the U.K.
    Many thanks

  6. Robert Downie

    The only reason I am writing this review, is that there appears to be no other way to contact USPS if you live in the UK, as your contact service requires US information.
    I have been tracking a shipment and 5 days ago everything stopped and I have no idea were my shipment is or when it’s due.
    The tracking number is LK136514518US.
    Can anyone help, or is your service really a shambles.
