Invalid region code:

Error message

Invalid region code: 

What it means

The North Korea (KP) addon's embedded libphonenumber region resolver throws "Invalid region code: <code>" when the requested region cannot be looked up in the bundled metadata (phone-type-formatter.kp.js:64). Same root cause as all phone-type-formatter addons: region code / loaded metadata mismatch.

Solutions

  1. Ensure phoneRegionCode matches the loaded addon ('KP' with phone-type-formatter.kp.js).
  2. Trim/uppercase the region code before constructing Cleave.
  3. Bundle every country addon your UI can select.
  4. Catch init errors and fall back to no formatting to avoid breaking the form.

Example fix

// before
new Cleave(el, { phone: true, phoneRegionCode: selectedCountry });
// after
import 'cleave.js/dist/addons/phone-type-formatter.kp.js';
const code = (selectedCountry || '').trim().toUpperCase();
if (code === 'KP') new Cleave(el, { phone: true, phoneRegionCode: code });
Defensive patterns

Strategy: validation

Validate before calling

const code = (selectedCountry || '').trim().toUpperCase();
if (!/^[A-Z]{2}$/.test(code)) {
  throw new Error('phoneRegionCode must be a 2-letter country code, got: ' + selectedCountry);
}

Type guard

function isKpRegion(code) {
  return typeof code === 'string' && code.trim().toUpperCase() === 'KP';
}

Try / catch

try {
  new Cleave(el, { phone: true, phoneRegionCode: code });
} catch (e) {
  if (e.message.includes('Invalid region code')) {
    console.warn('Falling back: no formatter for region ' + code);
  } else { throw e; }
}

Prevention

When it happens

Trigger: Formatting with phoneRegionCode that does not correspond to the KP addon metadata, an invalid country string, or empty code reaching R() while isNaN/null checks still pass the metadata branch.

Common situations: Copy-pasting config between apps with different addon files loaded; dynamic region selection where only one addon was bundled; typos like 'KP ' or 'kp1'.
