A CVV test i18n pass verifies that your card-verification field still behaves correctly once checkout is translated, localized, or rendered right-to-left. It is the part of payment QA that catches broken digit rules, missing mobile keypads, and error messages that leak sensitive input in markets you have not yet launched in. This guide covers what to check, which locales to prioritize, and how to keep the field compliant while it flexes across languages.

Key Features

• Locale-aware length rules: three digits for most brands, four for American Express, validated against the card type rather than a hardcoded global value.
• Correct input semantics: numeric keypad on mobile and card-security-code autofill in every supported language.
• Bidirectional safety: label alignment, tab order, caret movement, and digit entry verified under Arabic and Hebrew layouts.
• Translated helper and error text that never echoes the value the shopper typed.
• Masking, paste, and IME handling that behave identically across Latin, Cyrillic, and CJK input methods.
• Numbering-system coverage for locales that display or accept non-ASCII digits.
• Screen-reader and keyboard-only flows checked per locale, not just in the default language.
• Compliance-safe logging: no verification value written to analytics, debug logs, or crash reports.

Specs and method

The check combines an automated suite with a short manual checklist. Automation drives the field through every locale in your matrix, asserting digit acceptance, error states, and masking behavior on desktop and mobile viewports. The manual pass covers what scripts cannot judge: RTL visual order, translated copy length in tight layouts, and assistive-technology announcements. Deliverables are a locale matrix, a pass/fail report per browser, and reproduction steps for any field that fails.

What is a CVV test i18n check?

It is a localization-focused test of the card verification field, confirming that validation, masking, error text, and input behavior remain correct in every language and script your storefront supports.

Which locales should you test first?

Start with your highest-traffic markets, then add at least one right-to-left locale and one non-Latin script locale, since those expose layout and input bugs that Latin-only testing misses.

Do you need a real card to run these tests?

No. Sandbox card numbers from your payment provider cover validation and error paths, and they keep real cardholder data out of test environments entirely.
