Identify currencies by ISO codes

What you’ll practice

ISO currency codes show up in banking, travel, trading, and online checkout - this quiz helps you recognize them instantly. You’ll practice linking 3-letter ISO codes (like USD, JPY, ZAR) to the correct currency name.

Each question is multiple-choice with 4 options and there’s no timer, so you can focus on accuracy first and speed later.

Difficulty and quiz settings

Difficulty is mixed on purpose: familiar majors appear alongside regional and easily confused codes to keep the challenge balanced. Before you start, you can choose how many questions to play and select a difficulty level that matches your comfort.

Common pitfalls to avoid

Many mistakes come from similar-looking codes, currencies shared across multiple countries, or mixing up a country code with a currency code. Watch for lookalikes and remember that some currency names repeat while the ISO code is what stays specific.

• Don’t assume the first letter always matches the country name (e.g., CHF)
• Watch for currencies with similar abbreviations (AUD vs CAD, NOK vs DKK)
• Separate currency codes from country codes (SEK vs SWE)
• Remember currency unions and shared currencies (EUR, XOF, XAF)
• Treat “dollar/peso/krone” as families - use the ISO code to be precise

Tips to improve quickly

If you miss one, take a second to note the region and any pattern in the code, then try again later with a shorter set. Replaying with a higher difficulty after you’re consistent on the basics is the fastest way to lock in long-term recall.
