Phone number formats in Liechtenstein
Liechtenstein numbers are typically 7 digits nationally. In international format, it becomes: +423 + 7 digits.
Common patterns
- +423 XXX XX XX — common spacing for readability (7 digits after +423)
- 423XXXXXXX — digits-only format used in systems (E.164 without +)

Formatting tip
If you’re validating forms, store as E.164 when possible (example: +4232377299). Display with spaces for humans (example: +423 237 72 99).
