Two ranges, one network
Mastercard is the only major network operating two non-contiguous numbering blocks. The classic 51–55 range has been in use for decades and was steadily running out of available numbers as global issuance grew.
To solve that, Mastercard opened the 2221–2720 series. Cards on the new series behave identically in every respect — same length, same routing, same acceptance — and the only practical difference is that some very old terminals and hand-written validation scripts were never updated to recognise numbers beginning with 2.
- Classic range — 51 through 55, always 16 digits.
- 2-series range — 2221 through 2720, also always 16 digits.
- Both ranges validate with the Luhn check digit in the final position.
- Any validation rule that only accepts 51–55 will incorrectly reject legitimate 2-series cards.
Reading Mastercard product tiers
Mastercard's tier structure runs from Standard through Gold, Platinum, World and World Elite, with separate Business and Corporate lines. Each tier is issued on its own range, which is what allows a merchant to identify a premium card before the payment is authorised.
That visibility cuts both ways. Higher tiers carry higher interchange, so some merchants apply surcharges to premium cards where local rules permit it, while others use the tier as a positive signal when scoring a transaction for fraud.
Methodology
Distribution figures are computed automatically from the 11 Mastercard ranges within Kripicard's curated directory of 33 publicly documented issuer ranges. This is a reference sample chosen for documentation quality rather than a proportional sample of Mastercard's global allocation, so the percentages describe this dataset and not the worldwide Mastercard portfolio. The numbering ranges described on this page are fixed Mastercard standards and apply universally. Single-card lookups in the Kripicard BIN tool query a live database at request time.
Frequently asked questions
What numbers do Mastercard cards start with?
Mastercard uses two ranges. The classic range runs from 51 to 55, and the newer series runs from 2221 to 2720. Both are always 16 digits. The 2-series was introduced to expand the pool of available numbers as the older range filled up.
Why does my Mastercard start with 2?
It is issued on the 2221–2720 series, which Mastercard added alongside the classic 51–55 block. It is a fully standard Mastercard. Very occasionally, older payment terminals that were never updated fail to recognise the 2-series, but this is now rare.
What is a World or World Elite Mastercard BIN?
World and World Elite are premium Mastercard tiers carrying higher limits and additional benefits. Each sits on its own dedicated BIN range so the tier — and the higher interchange attached to it — is identifiable from the card number before authorisation.
How are Mastercard BINs split between credit and debit?
Across the 11 Mastercard ranges tracked in Kripicard's directory, credit accounts for 72.7%, debit accounts for 18.2%, prepaid accounts for 9.1%. Funding type is always kept on separate ranges because interchange and acceptance rules differ.
Is Maestro the same as Mastercard?
Maestro is a separate debit brand operated by Mastercard, with its own numbering ranges. Mastercard has been retiring Maestro in Europe in favour of standard Mastercard debit, so newer cards in those markets sit on regular Mastercard ranges.
Does Kripicard issue on Mastercard BINs?
Yes. Kripicard virtual cards are issued on Visa and Mastercard BINs through licensed issuing partners, so they are accepted anywhere those networks are supported online.
