What BIN 553370 Tells You

The first digit, 5, is the Major Industry Identifier under ISO/IEC 7812 and is reserved for Mastercard. Mastercard card numbers start with 51-55, 2221-2720 and run to 16 digits, so the prefix alone is enough to identify the network before any lookup happens.

The full 6-digit prefix narrows that down to one product from one issuer. The Central Trust Bank holds this range and issues it as a credit card, meaning purchases draw on a credit line and are settled later. The Fleet level marks it as a fuel and vehicle-expense card issued to companies for their drivers. The commercial flag matters for acceptance: business cards carry different interchange and are often excluded from consumer-only offers.

The country is that of the issuing bank, United States. It is the most useful single field for fraud screening: a mismatch between the issuing country and the billing or shipping country is one of the strongest signals available before authorisation. See the United States BIN lookup for other issuers in the same market.

Card Number Structure for 553370

A 16-digit Mastercard number in this range breaks down as follows:

DigitsPartMeaning
1 Major Industry Identifier 5 — Mastercard
1–6 BIN / IIN 553370 — the issuer range this page describes
7–15 Account identifier 9 digits assigned by The Central Trust Bank to the individual account
16 Check digit Computed with the Luhn algorithm over the preceding digits

The BIN describes the card product. Everything after it is specific to one account and should never be sent to a lookup service — our API rejects anything longer than 11 digits and redacts it from logs.

Verifying a Card That Starts With 553370

  1. Check the prefix. A lookup on 553370 confirms the range is live and returns the issuer, funding type and country above. A prefix that returns 404 was never allocated or has been retired.
  2. Check the full number with Luhn. The final digit is a checksum over the rest. A number that fails it was mistyped or generated. Use the Luhn calculator to see the arithmetic.
  3. Submit more digits if you have them. Issuers subdivide 6-digit ranges. An 8-digit lookup on this range may resolve to a more specific product than the 6-digit record, and the meta.longer_bin_available field tells you when that is the case.

What This Record Cannot Tell You

BIN data describes a card product, not a card. Nothing here says whether a particular number beginning 553370 was ever issued, whether it is active, what its balance is, or who holds it. Those answers only come from an authorisation request to The Central Trust Bank. For the broader picture, read what a BIN number is and how it is structured.
