USPS delivery tracking

The USPS offers both domestic and international services. The rate for sending a First Class Mail within the United States is $0.49 for the first ounce, as of 2014. Each additional ounce is charged $0.21. For large envelopes or flat parcels, the rate is $0.98 for the first ounce and $0.21 per additional ounce. Parcels and packages are charged $2.32 for the first three ounces and $0.18 per additional ounce. In addition to First Class Mail, the USPS offers Priority Mail Express for guaranteed overnight delivery to most locations and Priority Mail for non-guaranteed day-specific delivery within one to three days. Priority Mail is also available for First Class Mail and Standard Post for larger mail items and parcels.

While delivery within the U.S. is handled by the USPS, delivery outside the country is generally carried out by local mail services. For example, in the United Kingdom delivery of items sent with the USPS will be delivered by the Royal Mail. USPS’s international services include First Class Mail International, which was formerly known as Airmail. This class of service includes small packages weighing up to 1.8 kilograms or 4 pounds. First Class Mail International rates start from $1.15 for sending postcards, envelopes and flat mail items. Rates for sending an item with USPS’s First Class Package International Service for parcels start at $6.55. Actual rates depend on the destination, dimensions and weight of the item. Delivery times vary depending on the destination.

Other international services offered by the USPS include Priority Mai International, Express Mail International and Global Express Guaranteed. Priority and Express services can be used for sending items to almost every country in the world. Customs forms are generally required when sending all international mail, depending on the service level and the value of the item.
