IBAN validation API pricing comparison

The two pricing models are hard to compare at a glance because they do not even use the same time unit. iban.com quotes lookups per year on an annual license; we quote requests per month on a subscription. So instead of putting plan names side by side, each row below takes one iban.com plan quota and shows what that same validation volume costs on ibanchecker.cash. The pattern that emerges is the reason this page exists: the entire yearly quota of iban.com's Corporate plan fits inside a single month of our $29 plan.

Competitor prices are approximate, as published on iban.com in June 2026; check their site for current figures. And one honest caveat before the table: iban.com's top tier is truly unlimited, while our largest plan covers 5 million requests per month (60M+ per year), with custom volumes available on request. If you genuinely need uncapped volume, that difference matters and we would rather you know it now than after signing up.

Feature comparison

Both services do the core job well: MOD-97 checksum, country format rules, and bank identification from the bank code inside the IBAN. If that is all you need, you will not notice a quality difference between the two on a valid German or French IBAN. The differences are in how you buy, what surrounds the API, and one capability where iban.com is clearly ahead: bank-side account verification. We have marked that row honestly below, because pretending a competitor's strength does not exist is the fastest way to lose a reader's trust.

What switching actually involves

Migrations sound scary, so here is the realistic scope. Both APIs take an IBAN and return JSON with validity, country, and bank details. In most codebases the switch is one changed URL, one changed auth header, and a small mapping of response field names. A single validation request looks like this:

curl -X POST https://ibanchecker.cash/api/v1/validate \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"iban": "DE89370400440532013000"}'

The response includes the validity verdict, check digit result, country, BBAN breakdown, and the bank name and BIC where we can resolve them. We publish an OpenAPI 3.1 specification you can import into Postman or a code generator, so you can diff the two response shapes before writing a single line. If you want to test the waters first, the free tier is enough to replay a month of real traffic for most small teams, and the bulk checker lets you sanity-check a CSV of IBANs in the browser before you touch any code.

When iban.com is the better choice

Credit where it is due: iban.com is one of the longest-established names in this space, with a broader product portfolio than ours, including bank account verification (Verification of Payee), sort code validation, and VAT tools. If your compliance process requires confirming that an account actually exists at the bank, or matching the account holder name before payout, iban.com sells that as a paid verification product and we do not offer it today. iban.com also offers a truly unlimited tier, while our largest plan covers 5 million requests per month; if you validate more than that, talk to us about custom volume. Where we focus instead is structural validation, bank identification, bulk checking, and developer integration, at a price and self-serve experience built for smaller teams that do not need an enterprise sales process.
