Standard numbers are numbers that have a defined syntax, drafted and maintained by standard bodies, and embraced by organizations worldwide. Standard numbers are considered to be unique. They are assigned by the standard body or can be constructed in a specified manner to ensure uniqueness. They can be checked for validity and most of them carry checksums.

• they are compact

• they identify things or entities

• they can be printed, recognized, and compared for identification

• they can be processed by computers, for instance as a key in a database

• they are globally available

• they persist

The Java API for standard numbers provides

• a parser for standard numbers

• a formatter for standard numbers

• a checksum calculator
