IBAN Checker by ibanchecker.cash

Descripción

IBAN Checker by ibanchecker.cash adds real-time IBAN validation to your WooCommerce checkout. When a customer submits an order with an IBAN number, the plugin verifies it against the ibanchecker.cash API before the order is accepted.

What it does:

• Validates IBAN format, check digit (MOD-97), and country-specific length rules
• Blocks order submission if the IBAN is invalid with a clear error message
• Shows real-time formatting hints as the customer types (spaces every 4 characters)
• Optionally adds an IBAN input field to checkout if your theme does not include one

Supported countries: 92 countries including all SEPA and GCC regions

Features:

• Zero configuration needed, just enter your API key
• Configurable field name (works with any IBAN field, custom or default)
• Enable/disable without deactivating the plugin
• No IBANs are stored, fully GDPR compliant
• Vanilla JS only, no jQuery dependency for the frontend hint

Getting your API key:

1. Visit ibanchecker.cash/pricing
2. Choose the Free plan (100 validations/month at no cost)
3. Enter your email to receive your API key instantly
4. Paste it into WooCommerce > Settings > IBAN Validation

External services

This plugin connects to the ibanchecker.cash API to validate IBAN numbers entered at checkout.

What is sent and when: When a customer submits a WooCommerce order containing an IBAN, the plugin sends that IBAN (and your API key for authentication) to https://ibanchecker.cash/api/v1/validate over HTTPS. No other personal data (name, email, address, order details) is transmitted. Nothing is sent if the IBAN field is empty.

Data handling: ibanchecker.cash does not log or store submitted IBANs. Validation runs in memory and the IBAN is discarded immediately after the response.
