Spain Phone Number Format: Best Practices & Easy Tips

Reading Time: 6 minutes

Understanding the Spain phone number format is essential if you are calling Spain, doing business with Spanish clients, or setting up a local presence in the Spanish market. A correctly formatted Spain phone number helps avoid failed calls, reduces confusion, and ensures reliable communication during local and international calls.

Spain follows a clear and consistent Spanish telephone numbering plan. Every phone number uses a fixed structure, making it easier to recognize landlines, mobile phone numbers, and non-geographic services. Whether you are dialing from another country or making local telephone calls within Spain, knowing the correct format matters.

If you use a business phone system, cloud phone system, virtual numbers, or VoIP service, correct formatting becomes even more important. VoIP platforms depend on proper digit grouping, country code recognition, and international format support to route calls accurately across mobile networks and data systems.

For companies serving Spanish customers, the right Spain phone number format improves call success, lowers phone bills, and supports professional communication. Providers like Vitel Global help businesses manage Spanish phone numbers correctly across international markets, call centres, and remote teams.

Key Takeaways

• Spain phone numbers use +34 country code plus nine digits
• There is no trunk prefix or leading zero
• All local and international calls require dialing all nine digits
• Mobile numbers start with 6 or 7
• Geographic numbers usually begin with 8 or 9

Understanding the Spain Phone Number Format

The Spain phone number format follows a national system designed to keep dialing simple and consistent. Unlike some countries, Spain does not shorten numbers for local calls. The same digits are used for local calls, national calls, and international calls.

Country Code: +34

The Spain country code is +34. It is also called the international telephone code for Spain. You must use this code when calling Spain from other countries.

Example:
+34 9XX XXX XXX
instead of
9XX XXX XXX

The country code replaces the need for a trunk prefix. Spain does not use a trunk code such as “0”.

National Significant Number

A Spain phone number always consists of a nine digit number. These nine digits form the national significant number under the Spanish telephone numbering plan.

• No digits are removed
• No digits are added
• The full number is always required

This rule applies to landlines, mobile numbers, and non-geographic numbers.

Area Code Structure in Spain

Spain does not use traditional area codes. Instead, the first digit indicates the number type.

• 6 or 7 → mobile phone
• 8 or 9 → geographic numbers
• 800 / 900 → freephone numbers
• 901 / 902 → shared-cost services
• 803 / 806 / 807 → adult services or premium services

This structure avoids confusion and simplifies dialing arrangements.

Local Phone Number Rules in Spain

A local phone number in Spain always contains nine digits. There is no trunk prefix, and there is no need to dial differently when calling the same province.

• Local calls require full numbers
• Calling the same province still requires all digits
• No “0” is ever used

This approach ensures consistent routing across mobile networks and call centers.

Mobile Phone Numbers in Spain

A mobile phone number in Spain always starts with 6 or 7. These numbers belong to the Spanish mobile network and are used for both personal and business communication.

Examples:

National format:
6XX XXX XXX

International format:
+34 6XX XXX XXX

A Spanish mobile number follows the same nine-digit rule as landlines. Mobile numbers are widely used by Spanish customers, especially for internet access numbers, data services, and personal numbering.

How to Dial Spain Phone Numbers

Calling Spain requires understanding the difference between domestic dialing and international calls.

For Local Calls Within Spain

• Dial the nine-digit number
• No trunk prefix
• No area code changes

Example:
9XX XXX XXX

This applies even when calling the same city or same province.

For International Calls to Spain

To make international calls to Spain:

1. Dial your exit code (international access code)
2. Dial +34 (Spain country code)
3. Dial the nine digit number

Example:
+34 9XX XXX XXX

This format works from all other countries and supports international calling through VoIP, mobile networks, and traditional phone lines.

Formatting Spanish Phone Numbers Correctly

Correct phone number format improves call clarity and reduces dialing errors.

National Format

Spain uses spaces to separate digit groups. This improves readability without changing the number.

Example:
9XX XXX XXX

There are no hyphens, brackets, or trunk codes.

International Format

The international format always starts with +34, followed by nine digits.

Example:
+34 9XX XXX XXX

This format works best for cloud phone systems, virtual numbers, and international call routing.

Types of Spanish Phone Numbers

Geographic Numbers

Spanish geographic numbers usually begin with 8 or 9. These numbers are tied to physical locations and are commonly used by businesses that want a local presence.

• Begin with 8 or 9
• Used for offices and fixed phone lines
• Ideal for building trust in the Spanish market

Example:
91 (Madrid)

Non-Geographic Numbers

Non-geographic numbers are not linked to a specific location.

Common prefixes include:

• 800 / 900 – freephone numbers
• 901 / 902 – shared-cost services
• 803 / 806 / 807 – premium and adult services

These numbers are often used by call centres, customer support teams, and large multinational European businesses.

Special and Emergency Numbers

Spain reserves short numbers for emergency and public services.

• 112 – emergency services
• Other short codes for legal and medical advice

These numbers use special numbering ranges and do not follow the standard nine-digit rule.

Common Dialing Issues and Solutions

1. Missing Country Code

For international calls, forgetting +34 will cause call failure. Always include the Spain country code when calling from abroad.

2. Incorrect Digit Count

Spain phone numbers must contain exactly nine digits. Dialing fewer or extra digits affects dialing arrangements and causes call errors.

3. Wrong Number Type

Calling a mobile number as a landline or vice versa may affect costs. Mobile numbers, geographic numbers, and freephone numbers follow different billing rules.
