Issue number

Issue number may refer to:

• The intra-year numbering of periodical literature such as magazines.
• A supplementary number to the account number of certain debit cards, primarily United Kingdom ones such as Switch and Maestro. Because the bulk of the account number is determined by the bank account number, the card number cannot be changed if the card is lost or stolen (without changing the underlying bank account number), and instead the issue number is changed.
