## UPC-A vs EAN-13 codes
UPC-A is a special case to handle if you need to cater for it. Android's SDK officially supports UPC-A but iOS does not, instead they handle the code as EAN-13. Since EAN-13 is a superset of UPC-A, with an extra 0 digit at the front.
This means, the `upc-a` types are reported under the `ean-13` umbrella type on iOS:
```jsx
const codeScanner = useCodeScanner({
codeTypes: ['upc-a'], // <-- ✅ We configure for 'upc-a' types
onCodeScanned: (codes) => {
for (const code of codes) {
console.log(code.type); // <-- ❌ On iOS, we receive 'ean-13'
}
}
})
```
You will need to keep this in mind and do the conversion from EAN-13 to UPC-A yourself. This can be done by removing the front `0` digit from the code to get a UPC-A code.
