A fax to a Spanish landline, no machine needed
Nine digits and the +34 country code: your PDF reaches a Spanish landline with no fax machine or software. One page free, PDF delivery receipts if the file calls for them.
No Spanish number opens with a zero. Landlines start with 9 — or, more rarely, 8 — and their first digits signal the province: Madrid 91, Barcelona 93, the Valencian Community 96, Seville under 954 and 955, Zaragoza 976. A 6 or 7 up front gives away a mobile, which accepts no fax.
In Spain, fax lives chiefly in gestorías — offices that carry the administrative formalities of individuals and small businesses alike. Notary offices, private clinics, mutual insurers, and a portion of hotels also keep an active line.
A confusion persists around the "burofax": this Correos service delivers a printed document with proof of content. It isn't fax, and when a burofax is expressly required, a regular fax will not do as a substitute.
Choose Spain, drop both the +34 and the 0034 prefix, and follow the format shown in the table. The first page is always free, regardless of how many transmissions you send; from page two onward, each fax is €3.99 including VAT. Need a dated record? PDF delivery receipts cost €2.99 including VAT, charged only when the document actually reaches its destination.

Spain: organisations that still receive faxes
- Town councils (ayuntamientos) and local branches of SEPE or Social Security: here and there, a line remains, but the bulk of procedures have migrated to electronic headquarters and their registry.
- Private clinics, mutual insurance companies, health insurers and pharmacies: authorizations, reports and reimbursement documents are still sent by fax machine.
- The Spanish judicial system favors LexNET, the shared platform for lawyers and procuradores; litigants file their documents at the court registry or use the authorized online services.
- Gestorías — the administrative agencies that handle paperwork for both businesses and individuals — notaries and insurers continue to receive signed documents by fax, each following their own practices.
No organisation number is published here: take the one from your latest letter, or from the official website.
The official digital channel
Massive investment in digital identity: an electronic certificate or Cl@ve unlocks the online portals of both Social Security and the Agencia Tributaria (AEAT); the General Electronic Registry receives filings for any government agency; DEHú centralizes official notifications; LexNET connects legal professionals.
Spain: time difference and office hours
| Time zone | The peninsula and the Balearic Islands follow UTC+1 (UTC+2 in summer); the Canary Islands operate on UTC+0, then UTC+1 when summer returns. |
|---|---|
| Difference from Paris | Mainland Spain and the Balearic Islands keep the same time, while the Canary Islands run one hour earlier. |
| Usual hours | Government offices generally operate from 9 AM to 2 PM. Lots of companies pause around noon and adopt uninterrupted summer hours; a fax arriving after 3 PM on Friday usually has to wait until Monday. |
Spain: questions about sending
- Fax or burofax: what's the difference?
- They are two different things. The burofax, a postal product from Correos, concludes with the delivery of a printed document whose content can be certified. Fax, on the other hand, travels over the telephone line to a fax machine. One does not replace the other.
- Do I need to dial the province prefix?
- The full number has nine digits, so copy them all exactly; +34 is optional, but do not add a leading zero. Example: 91 123 45 67 (Madrid).
- My number starts with 902: why is it rejected?
- The 90x and 80x ranges cover special numbers — toll-free, shared-cost or premium-rate — which the form excludes in favor of geographic landlines. Ask your contact for their direct fax line: it will most often start with a 9 or an 8, the province prefix first.
