What is a MasterCard Issue Number

A card’s issue number was first introduced to permit the alteration of a static number when it was reissued or replaced. Banks and merchants have become less dependent on them in recent years.

What’s An Issuer’s Number?

Numbers on the card that were issued indicate the date they were issued or replaced. They had these numbers displayed in a sequence to display the time the new card was issued. Businesses like MasterCard used numbers from credit cards as an account number that would last forever, and it wouldn’t change after the card was issued. The card instead had a different expiration date and a unique CVC/CVV code, and a unique, sequenced issue number.

Issue numbers have never been normal across these countries, either in the United States or Canada. However, they’re often seen in the UK and Europe; however, they are getting rarer. The majority of the new debit and credit cards do not have them anymore. The cards with issue numbers have an unchanging prefix type code and account number. The issue number was designed to make it easier for institutions to distinguish the present card from an earlier issue of the identical card.

Finding Issue Number on Card

Many people confuse the 3-digit CVC/CVV code on the reverse of the card as its issue number. But, they do not serve identical functions. The issue number is usually located on the front of a credit or debit card, along with the dates when the card could be used before expiring. Sometimes, issue numbers were located on the bottom left edge of the card. It might even include “issue number” alongside the digits.

Issue numbers are either one or two-digit numbers which read “1” or “01” at the time of the initial issue of a credit card. If there is no similarity in the places listed in the above list, the card does not possess the issue numbers. A second issue on a card could be “2” and “02” The numbers will increase each time a new card is issued. In the present, as the debit or credit card number is changed when the card is issued and issued, there is no requirement for an issuer number.

The Discontinuation Of Issue Numbers

As computers have evolved into databases over the last couple of years, it is now much easier to track customers’ accounts as never before. So businesses and banks no longer require an issue number to their systems. Although the card’s number is changed with each reissue, the ID number internal for these institutions is identical throughout the lifetime of the debit or credit card, linking the various accounts and cards of a single person. The cardholder may not know the ID number since it’s not used outside the institution that issued the card. However, these ID numbers provide the user with an additional layer of protection.

There are probably only a few MasterCard issue numbers that are still available. In the UK, Switch was a well-known debit card payment system using issue numbers. Then, in the year 2002, Switch joined with Maestro, an international credit card issued by MasterCard. It was in 2011 that Maestro became standard internationally and became a special card. Since then, all cards with an issue number lapsed, and current valid cards do not require an issuer number.
