Machine-readable passport

A machine-readable passport (MRP) is a machine-readable travel document (MRTD) with the data on the identity page encoded in optical character recognition format. Many countries began to issue machine-readable travel documents in the 1980s.

Most travel passports worldwide are MRPs. They are standardized by the ICAO Document 9303 (endorsed by the International Organization for Standardization and the International Electrotechnical Commission as ISO/IEC 7501-1) and have a special machine-readable zone (MRZ), which is usually at the bottom of the identity page at the beginning of a passport. The ICAO Document 9303 describes three types of documents. Usually passport booklets are issued in "Type 3" format, while identity cards and passport cards typically use the "Type 1" format. The machine-readable zone of a Type 3 travel document spans two lines, and each line is 44 characters long. The following information must be provided in the zone: name, passport number, nationality, date of birth, sex, and passport expiration date. There is room for optional, often country-dependent, supplementary information. The machine-readable zone of a Type 1 travel document spans three lines, and each line is 30 characters long.

Machine-readable passports enable faster processing of arriving passengers by immigration officials, and greater accuracy than manually read passports, as well as faster data entry and data matching against immigration databases and watchlists.

Passport booklets have an identity page containing the identity data. This page is in the TD3 size of 125 × 88 mm (4.92 × 3.46 in).

The data of the machine-readable zone consists of two rows of 44 characters each. The only characters used are A–Z, 0–9 and the filler character <.

The format of the first row is:

In the name field, spaces, hyphens and other punctuation are represented by <, except apostrophes, which are skipped. If the names are too long, names are abbreviated to their most significant parts. In that case, the last position must contain an alphabetic character to indicate possible truncation, and if there is a given name, the two fillers and at least one character of it must be included.
