Spain Phone Number Format & Country Code +34
Spanish numbers are 9 digits with no trunk prefix — the same digits are used for both local and international dialing. Mobile numbers start with 6 or 7, while landlines start with 9 or 8. Simply add +34 before the 9-digit number for international calls. To dial a Spain number internationally, replace the local trunk prefix with +34. For example, 612 345 678 becomes +34 612 345 678. NumSwift converts between these formats automatically, validating each number against Spain's numbering plan.
