Banking SRB TravisCI build License PHP Packagist Version GitHub release

This library contains useful banking functions in use by banks in Serbia. By the order of the Governor of National Bank of Serbia, account numbers are structured in the following manner:

  • 3 digits represent bank ID Fixed value, assigned by the NBS. List, as of 16 April 2018 PDF
  • 13 digits represent account number, bank manages this number
  • 2 digits represent checksum number, calculated using ISO 7064 MOD 97-10

When payment reference numbers are generated, checksum goes to the front of the number, It is calculated using the same ISO 7064 MOD 97-10 algorithm as bank account number checksum. Reference number must consist only of digits, and if it should include a letter, that letter is transformed into a number, to generate checksum. Conversion follows this pattern: A=10, B=11, C=12, ..., Y = 34, Z = 35.
