Spain sits at a commercial crossroads few European markets can match: it is simultaneously an EU economy of scale, the natural bridge between European head offices and Spanish-speaking Latin America, and one of the world's most visited countries. A +34 number is therefore rarely just a local contact point — for many Temptera customers it anchors a Spanish-language operation that serves callers on both sides of the Atlantic. This page covers how Spanish numbering actually works, who regulates it, and what documentation the different +34 ranges call for.

Spain numbering plan: prefixes and formats

Spain operates a closed nine-digit numbering plan behind country code +34: every subscriber number is nine digits long and is dialled in full for every call, local or long-distance, with no trunk prefix. The first digit signals the number class, and for geographic numbers the leading digits identify the province — 91 serves Madrid, 93 serves Barcelona, 96 covers Valencia and 95 reaches Seville and much of Andalusia. Geographic capacity sits in ranges beginning with 9, with additional geographic allocations opened in ranges beginning with 8 that map to the same provincial areas.

  • Geographic (9x and 8x): provincially anchored fixed numbers; the prefix tells a Spanish caller roughly where the business sits, which still carries weight in a market where regional identity matters commercially.
  • Mobile (6 and 7x): Spanish mobile numbers begin with 6, and further mobile capacity has been released in ranges starting with 7.
  • Freephone (900 and 800): free to the caller from within Spain, with the receiving business carrying the inbound charge — the standard choice for consumer-facing service lines.
  • Special-tariff (901 and 902): non-geographic ranges where the caller pays a special retail rate; Spanish consumer-protection rules have steadily discouraged their use for basic customer service, pushing businesses toward geographic or 900 alternatives.

The practical consequence of the closed plan is predictability: a valid Spanish number always formats as +34 followed by exactly nine digits, which simplifies validation in CRMs, diallers and IVR logic compared with markets that mix number lengths.

Who regulates numbering in Spain

Numbering in Spain falls under the CNMC — the Comisión Nacional de los Mercados y la Competencia — the converged authority that combines telecoms oversight with Spain's competition and markets functions. For telephone numbering specifically, the CNMC administers the national numbering plan, assigns blocks within the geographic, mobile, freephone and special-tariff ranges to licensed operators, and supervises how those operators put the resources into service.

The CNMC also sets the rules that reach end users of Spanish numbers: registration obligations attached to particular ranges, the conditions under which numbers may be sub-assigned to business customers, and the framework for number portability between Spanish operators. When Temptera collects documents before activating a +34 range, it is these carrier-level obligations flowing down to the number holder.

Documents and verification for Spain numbers

Spanish number registration follows the pattern of most western EU markets, but with documentation types that are distinctly Spanish. Individual registrants are generally asked for a government identity document — for residents this is typically a DNI or NIE, while foreign applicants can usually present a passport. Corporate registrations on certain ranges call for Spanish company evidence, such as a CIF tax identification code or an extract from the Registro Mercantil, and some geographic allocations additionally expect address evidence connected to the province of the prefix, so a 91 number may be documented differently from a 96 number.

Because these classes differ range by range — a 900 freephone line, a provincial number, and a nationwide range do not carry identical obligations — Temptera resolves the question at the moment it matters: when you select a specific Spanish number, the order screen lists exactly which documents that range requires before activation.

What businesses use Spain numbers for

Spanish numbers tend to be bought for reasons rooted in how Spain's economy is actually structured — its language reach, its tourism engine, and its role as a European base for Iberian and Latin American operations.

  • Latin America gateway operations: multinationals frequently run Spanish-language shared-services and sales desks out of Madrid or Barcelona; a 91 or 93 number gives those teams a credible Spanish identity while agents handle traffic spanning Iberia and the Americas.
  • Tourism and hospitality: hotels, villa managers and travel operators along the Costa del Sol, in the Balearics and the Canaries field booking calls year-round; a provincial number or a 900 freephone line lets international operators answer Spanish guests without a physical front desk in every location.
  • Cross-border e-commerce support: EU retailers selling into Spain increasingly need a Spanish-dialled support line, since consumer-facing rules and buyer expectations both favour a local or freephone contact over a foreign number on the returns page.

How to get a Spain number

  1. Choose the Spanish number class that matches your presence: a provincial prefix such as Madrid 91 or Barcelona 93, a nationwide-reachable range, or a 900 freephone line.
  2. Review the registration classes flagged for that range at checkout — identity document, Spanish address evidence, or company papers such as a CIF — and upload what applies.
  3. Submit the order and let the range-specific verification clear; the expected handling for each Spanish number class is indicated alongside the listing.
  4. Once the +34 number goes live, attach it to your SIP trunk or hosted PBX from the Temptera dashboard and define where inbound calls should land.
  5. Place test calls from a Spanish line, confirm audio and caller ID behave as expected, then add failover routes and business-hours rules before going to market.

Frequently asked questions

Do I need a Spanish company or CIF to buy a +34 number?

Not for every range. Many Spanish geographic and national numbers can be registered to a foreign business using standard identity documents, while certain classes ask for Spanish corporate papers such as a CIF tax code or a Registro Mercantil extract. Each +34 range lists its own registration classes, and Temptera displays the exact document set for the specific number you select at order time.

Can I get a Madrid 91 or Barcelona 93 number without an office in that city?

Often yes, depending on the range. Spanish geographic prefixes are tied to provinces, so some 91 or 93 allocations ask for an address that corresponds to the Madrid or Barcelona area, while others accept a broader Spanish or foreign business address. The address class that applies to the exact number you pick is shown before you commit to the order.

How many digits does a Spanish phone number have?

Spain uses a closed nine-digit plan. Every fixed and mobile subscriber number is nine digits long and is dialled in full nationwide, with no separate trunk prefix for domestic calls. Internationally, callers dial +34 followed by those nine digits, so a Madrid number appears as +34 91 followed by seven further digits. This uniform length makes Spanish numbers straightforward to validate in CRMs and dialler software.

What is the difference between 900 and 901 or 902 numbers in Spain?

Spanish 900 numbers are freephone, so the receiving business bears the cost and callers inside Spain pay nothing. The 901 and 902 ranges carry special retail tariffs for the caller, and Spanish consumer-protection rules have pushed companies to offer geographic or 900 alternatives for customer-service lines. For inbound support aimed at Spanish consumers, a 900 or a provincial number is usually the safer commercial choice.

Can I answer calls to my Spain number from outside Spain?

Yes. Temptera terminates inbound calls to your +34 number over SIP to whatever destination you configure, so a Barcelona-facing sales line can ring a contact centre in Bogotá, a PBX in Frankfurt, or softphones anywhere. The number keeps its Spanish identity for callers while your team answers wherever it sits, subject only to the registration documents the chosen range requires.
