Techical Specifications of the Machine Readable Zone
The Machine Readable Zone (MRZ), also known as the optical zone, is a rectangular region on the passport’s face that contains biographical information about the passport holder. This zone is essential for facilitating quick and accurate processing of passports by automated machines, such as border control scanners and ticket vending machines. The format and layout of the MRZ have been standardized by the International Organization for Standardization (ISO), ensuring consistency across different passport types.
Role of the International Organization for Standardization (ISO)
The International Organization for Standardization (ISO) plays a crucial role in standardizing the Machine Readable Zone (MRZ) format and layout. In 1987, ISO standardized the MRZ format, known as ISO/IEC 7501-1, which Artikels the specifications for the MRZ, including the size, location, and orientation of the zone, as well as the structure and content of the biographical information. By standardizing the MRZ format, ISO enables the widespread adoption and interoperability of passport-reading technologies across different countries and regions.
Data Stored in the MRZ
The Machine Readable Zone (MRZ) stores essential biographical information about the passport holder, including:
- Names
- Dates of birth
- Passport numbers
These include the holder’s surname and first name(s) in the format specified by the issuing country, such as Mr./Mrs./Ms./etc. followed by surname and first name(s).
Dates of birth, including the day, month, and year of birth, are represented in a numeric format in the MRZ.
Passport numbers are unique identification numbers assigned to each passport holder, used for identification and tracking purposes.
Passport numbers are alphanumeric strings that consist of letters and numbers, typically 9 or 10 characters in length, and usually follow a specific prefix and suffix convention.
Passport numbers must adhere to the ISO/IEC 7501-1 standard, ensuring consistency across different passport types.
Format and Layout of the MRZ
The MRZ format is divided into two lines, each containing 44 characters:
“The MRZ is formatted according to the following structure:”
Line 1: AA BB CCCC DDDDD EFFFFFF
Line 2: GGGGG HHHHH I JJJJJ KKKKK
where:
– AA is the two-character country code
– BB is the passport type (e.g. “P” for Machine Readable Passport, “O” for Old Machine Readable Passport)
– CCCC is the passport number
– DDDDD is the nationality name
– EFFFFFF is the holder’s surname
