Discover ranges

  • 6011 — original Discover range.
  • 622126–622925 — a UnionPay range that is accepted on the Discover network in the US through a reciprocal agreement. These are UnionPay cards, not Discover-issued.
  • 644–649 and 65 — modern Discover range.
  • Length: 16–19 digits (16 is by far the most common).

Because Discover also routes UnionPay and Diners Club cards, check the full BIN with our BIN checker rather than relying on the first two digits.
