The UPU S10 standard defines a system for assigning 13-character identifiers to international postal items for the purpose of tracking and tracing them during shipping. The standard was introduced on 18 April 1996, [ 1 ] : 4 and is currently in its 12th version.
It is a unique ID number or code assigned to a package or parcel. The tracking number is typically printed on the shipping label as a bar code that can be scanned by anyone with a bar code reader or smartphone. In the United States, some of the carriers using tracking numbers include UPS, [1] FedEx, [2] and the United States Postal Service. [3]
Numeric: n digits are encoded in ⌊ n/3 ⌋ +1 code words, up to a maximum of 44 digits in 15 code words. Text : Each code word represents two base-30 digits, which are used by a system of four submodes to represent the printable ASCII characters (plus CR , LF and HT ):
A UPC barcode. The Universal Product Code (UPC or UPC code) is a barcode symbology that is used worldwide for tracking trade items in stores.. The chosen symbology has bars (or spaces) of exactly 1, 2, 3, or 4 units wide each; each decimal digit to be encoded consists of two bars and two spaces chosen to have a total width of 7 units, in both an "even" and an "odd" parity form, which enables ...
Track 1 can store up to 79 alphanumeric characters. ISO 7813 specifies the following structure for track 1 data: [2] SS : Start sentinel "%" FC : Format code "B" (The format described here. Format "A" is reserved for proprietary use.) PAN : Payment card number 4400664987366029, up to 19 digits; FS : Field separator "^"
Each different type of trade item is allocated a different number and, for ease of administration, it is recommended that companies do this sequentially (001, 002, 003, etc.). T14 is a check digit, which follows the standard modulo 10 calculation. [5] Note that GTIN-12 numbers can be encoded as GTIN-13 by adding a padding zero in the T2 position.
From 2002 until 2009, Kanada held the world record calculating the number of digits in the decimal expansion of pi – exactly 1.2411 trillion digits. [1] The calculation took more than 600 hours on 64 nodes of a HITACHI SR8000/MPP supercomputer. Some of his competitors in recent years include Jonathan and Peter Borwein and the Chudnovsky brothers.
Simon Plouffe. Simon Plouffe (born June 11, 1956) is a French Canadian mathematician who discovered the Bailey–Borwein–Plouffe formula (BBP algorithm) which permits the computation of the nth binary digit of π, in 1995.
