Run from a United States-region account between 20 Jul to 07 Sep 2026, with the billing address set to the issuer default unless noted. Declines were logged with the reason the gateway returned.

Failures we could not fix

We only saw failures on Best Buy when the account region did not match the card country. With both set to United States it passed.

What to change before you retry

Setup notes for Karat Financial

  1. You can hold several cards at once (Multiple). Split them by merchant, not by amount. It makes a failed charge far easier to trace.
  2. Set the billing address to exactly what Karat Financial generates for United States. Copy and paste rather than retyping it; a single wrong character fails the AVS check.
  3. This range does not advertise 3-D Secure. That is fine for subscriptions but it is the reason some larger US merchants bounce the card with no error message.

Worth it?

We would rank it above average and below the top tier. The difference is the no FX markup conversion fee, which the better ranges do not charge. Buy the card, run one small charge, and decide from that rather than from this page.

FAQ

What does the 265829 BIN tell a merchant?

In practice the checkout reads Karat Financial / United States / Debit and decides. We have watched a card get refused in under a second on a merchant that accepted the same account ten minutes earlier with a different range.

Is 265829 a real card number?

Six digits of a sixteen-digit number. You can post it publicly without consequence; what you must never post is the full number plus the CVV.

Why would 265829 be declined if the range is fine?

Changing one variable at a time is the only way to diagnose this. Address first, then card, then the connection country. We have seen people change all three and learn nothing.

Can thousands of people share the same BIN?

Shared by design. Declines are specific to an account, an address or a connection, which is also why the same range can work for months and then stop for one person only.

How we got these numbers

We bought a Karat Financial card, funded it, and pushed 192 charges through live merchant checkout pages between 20 Jul to 07 Sep 2026. Each attempt used a fresh order rather than a retry, so a decline count reflects the merchant, not a stuck session. 136 cleared.

Counting rules

Renewals count alongside first charges, which is why a range that passed once and failed a month later reads lower here than on a first-charge-only list. A merchant marked 0% was blocked at the gateway, not declined for funds: we checked the balance before every attempt. Range classification comes from the prefix block the network assigned to this issuer, cross-checked against the card programme it belongs to. Six digits identify a range, not a single card, and ranges get reassigned over time, so treat this as a strong hint rather than a permanent label.
