How to send a fax to Spain

Why fax to Spain?

Fax remains a common channel in Spain for communicating with government offices, banks, legal firms, and healthcare providers.

• Business hours: Spanish offices typically operate 09:00 – 14:00 and 16:30 – 19:30 CET (UTC+1), or CEST (UTC+2) in summer. Many government offices use a continuous morning schedule (jornada intensiva) of 08:00 – 15:00, especially in summer. Faxes sent outside these hours will queue at the receiving machine.

• Include a reference number if you have one: if you are responding to a case, claim, or application, include the reference number (número de referencia or número de expediente) prominently on the first page or cover sheet.
• No area code to worry about: unlike many countries, Spain uses a closed numbering plan. The full 9-digit number is always the same whether you are calling from within Spain or internationally. Just enter all 9 digits.
