Spanish Virtual Phone Numbers for business
Give customers in Spain a +34 business number and answer through SIP, your PBX or a mobile. Compare local, mobile and toll-free options, then choose the number and answering route for your team.
A Spanish contact line for the team that answers.
A Spanish DID is the public +34 number customers call. A SIP endpoint, PBX extension or chosen phone destination is where your team answers. A Madrid contact line can enter a sales queue while a separate support number reaches the service team.
Choose the location and number category for your customers, then confirm the selected offer's requirements. Remote answering and eligibility to hold the number are separate matters. Plan which destination rings first and how busy or unanswered calls are handled; our call forwarding guide explains these options.
Connect your Spanish number to business voice services.
Numbers are just the start - outgoing calls, SMS and a full phone system work from the same account.

Choose the Spanish number category for your customers.
A geographic line, mobile-format number and freephone service answer different contact needs. Use this guide to compare their purpose, then check the live inventory and exact prefix in your personal account.
| Number category | Business purpose | Check before ordering |
|---|---|---|
| Local / geographic | A contact line associated with a Spanish province or numbering area. | Location, assigned prefix and eligibility for that area. |
| Mobile | A number in an assigned Spanish mobile range. | Required voice and messaging capabilities of the selected offer. |
| Toll-free: 800 / 900 | A freephone contact for callers in Spain. | The inbound charges to your business and caller-network reachability. |
| National / non-geographic | A contact option that is not presented as one city line. | The actual prefix, caller charges and permitted use. Do not infer these from the catalog label. |
Spain's national numbering plan assigns different ranges to geographic and mobile services. The live price card shows current offers; this category guide is not a stock reservation or a promise that every prefix is available.
Publish +34 with the complete Spanish number.
Ordinary Spanish geographic and mobile numbers use nine national digits. In international format, put +34 before all nine digits. Keep the geographic prefix as part of that complete number; do not shorten it to a local subscriber number or insert an extra zero.
For example, 91 is a familiar Madrid geographic prefix and 93 is used in Barcelona ranges. These are prefix examples, not complete numbers or reservations. The CNMC's geographic numbering document lists the provincial ranges. Check the actual location and offer before ordering.
800 and 900 freephone numbers are different from 901 and 902. Confirm the precise prefix rather than treating every number starting with 9 as toll-free. CNMC explains that the business receiving an 800/900 call pays for the service; review the selected offer's incoming charges and reachability.
For a team answering outside Spain, keep the public +34 contact number separate from the destination that rings. Check rental and setup independently from usage. If the route forwards to an ordinary mobile or landline, compare the outgoing rate for that destination and check a test call's recorded charge.
How to connect a Spanish business number.
Requirements for your selected Spanish number.
Requirements depend on number type, local telecom rules and use case. We confirm the required documents before activation so your order stays compliant.
Questions before ordering a number in Spain.
Choose the number category, publish the correct +34 format and plan the route your team will answer.
How much does a virtual number in Spain cost?
Compare the local, mobile, toll-free and national rows in the live price card. The final price depends on the exact available number and offer. Rental, any setup fee and call usage are separate parts of the total. Your personal account shows the selected supplier's conditions and charges.
How fast is activation?
Standard activations are usually fast after availability and compliance checks. Regulated number types may take longer if documents are required.
Can calls be forwarded internationally?
Yes. Calls to your Spanish number can be routed to SIP, an existing PBX, a mobile or a call center destination. Confirm the destination and any usage charges, then test the main and fallback routes before publishing the number to customers.
Are there KYC requirements?
Requirements depend on number type, country and use case. We check required documents before activation.
How do I write a Spanish number with +34?
Put +34 before the complete nine-digit national number for an ordinary geographic or mobile line. Keep its prefix within those nine digits. Do not add an extra domestic zero or publish only the final local digits.
Should I choose a Madrid or Barcelona number?
Choose the area your customers should associate with the contact line, then confirm its actual prefix, availability and eligibility. Madrid 91 and Barcelona 93 are examples of geographic prefixes; the selected offer, rather than the location of your SIP phone, determines which number you can order.
Are 800, 900, 901 and 902 all toll-free?
No. 800 and 900 are freephone categories for callers in Spain; 901 and 902 are not freephone. Check the exact prefix and charges. The Community of Madrid's consumer guidance explains the distinction.
Can I use an inbound number as outgoing Caller ID?
Confirm the intended Caller ID, number category and permitted route with the team before making outgoing calls. An incoming number and the destination that answers it do not by themselves establish which outbound presentation is available for your account.
