Frequently Asked Questions
The country code for San Marino is +378. This code is required when dialing a San Marino number from another country. All San Marino numbers, regardless of type, are prefixed with +378.
Use the E.164 format, which is +378 followed by the 8-digit subscriber number. For example, a landline number would be formatted as +37805491234, and a mobile number as +37861234567. This international standard ensures compatibility with global systems.
Use the regular expression `^\+378 0549 \d{4}$` to validate San Marino landline numbers. This regex checks for the correct country code (+378), area code (0549), and four-digit subscriber number. Ensure the regex is appropriately escaped for your programming language.
The area code for all landlines in San Marino is 0549. This area code is used for domestic routing and is also reachable using the Italian country code +39 due to historical ties.
+378 is the internationally assigned country code for San Marino, designated by the International Telecommunication Union (ITU-T). This code uniquely identifies San Marino in the global telecommunications system and ensures interoperability with other countries.
San Marino mobile numbers are identifiable by the leading '6' after the country code. They follow the format +378 6XXX XXXX. This allows for easy distinction from landlines and premium rate services.
Premium rate services in San Marino are identified by the prefix '7' after the country code (+378). These numbers usually indicate specialized services or higher call charges. The full format is +378 7XXX XXXX.
Store San Marino phone numbers in a VARCHAR(15) field in your database, using the E.164 format (+378XXXXXXX). Include a separate field for the number type (landline, mobile, premium) and implement a check constraint to ensure only valid numbers are stored.
The Information and Communication Technology Authority (ICT Authority) regulates and supervises San Marino's telecommunications landscape. Established by Delegated Decree no. 146/2018, it ensures the ongoing development, security, and stability of the telecom system.
The Italian country code (+39) may work for San Marino landlines due to historical ties, but the official and recommended practice is always to use the San Marino country code (+378). Use +39 only when dealing with legacy systems that may require it.
San Marino's telecommunications network boasts comprehensive Fiber to the Home (FTTH) coverage and advanced 5G mobile network implementation. This infrastructure is remarkably advanced, positioning San Marino as a leader in technological adoption, often outpacing larger countries.
Remove all non-digit characters from the phone number and prepend +378 if not already present. For example, the javascript function `formatToE164('0549 1234')` will return '+37805491234'. This ensures your number strings adhere to the international standard.
For the most up-to-date information about regulations and future developments in San Marino telecommunications, consult the official ICT Authority website and their technical documentation. The Telecommunication Sector, contactable at tlc@pa.sm or +378 0549 882552, also handles technical and administrative aspects.
Key emergency numbers in San Marino include 112 (European emergency number), 113 (Police), and 118 (Medical emergencies). Ensure your applications comply with regulations regarding accessibility to these numbers.

San Marino Phone Numbers: Format, Area Code & Validation Guide
This guide provides a deep dive into the telephone numbering system of San Marino, offering developers a practical understanding of its structure, validation rules, formatting best practices, and integration considerations. You'll find everything you need to confidently handle San Marino phone numbers in your applications.
Quick Reference
Let's start with a quick overview of the key elements of San Marino's phone number system:
Understanding San Marino's Telecommunications Landscape
San Marino, despite its small size, boasts a remarkably advanced telecommunications infrastructure. Overseen by the Information and Communication Technology Authority (ICT Authority), the system features a state-of-the-art digital network with comprehensive Fiber to the Home (FTTH) coverage. This robust infrastructure is a testament to San Marino's commitment to technological advancement. You might be surprised to learn that this small nation has been a pioneer in adopting new technologies, often outpacing larger countries in its implementation.
Digital Transformation and the ICT Authority
San Marino's digital transformation has been nothing short of remarkable. The country's compact size has allowed for swift deployment of cutting-edge technologies, resulting in near-universal network coverage. Key advancements include:
As a developer, understanding this context helps you appreciate the advanced nature of San Marino's telecommunications system and its potential for future innovation. The ICT Authority, established by Delegated Decree no. 146/2018, plays a crucial role in regulating and supervising this dynamic landscape, ensuring its continued development and security. This is important for you because it means you can rely on a stable and well-regulated environment for your telecommunications-related development projects.
Numbering Structure and Technical Standards
San Marino's telephone system adheres to International Telecommunication Union (ITU-T) recommendations, ensuring global compatibility. This adherence to international standards is crucial for developers, as it simplifies integration with international systems.
General Number Format
The standard format for San Marino phone numbers is 8 digits, preceded by the country code:
Where:
+378
is the country code for San Marino.XXXX XXXX
represents the 8-digit subscriber number.Service-Specific Number Formats
San Marino utilizes distinct prefixes within the subscriber number to differentiate between service types. This allows for efficient routing and clear service identification. You should familiarize yourself with these distinctions to ensure accurate number processing in your applications.
1. Geographic Numbers (Landlines):
All landlines utilize the
0549
area code, simplifying domestic routing. Interestingly, due to historical ties, landlines can also be reached using the Italian country code (+39) followed by the 0549 area code and the subscriber number. This historical context is important for developers dealing with legacy systems or cross-border communication.2. Mobile Numbers:
Mobile numbers are easily distinguished by the leading
6
.3. Premium Rate Services:
Premium rate services are identified by the
7
prefix. These numbers are typically associated with specialized services or higher call charges.Implementation Guidelines for Developers
This section provides practical guidance on validating, formatting, and handling San Marino phone numbers in your applications.
Number Validation
Robust validation is crucial to ensure data integrity. You should always validate user input to prevent errors and ensure that your application handles phone numbers correctly. Here are some regular expressions you can use for validation in JavaScript:
These regular expressions check for the correct country code, prefixes, and number length. Remember to test your validation logic thoroughly with various valid and invalid inputs.
Number Formatting
Consistent formatting enhances usability and interoperability. The E.164 format (
+CountryCodeSubscriberNumber
) is the international standard and is recommended for storing phone numbers. Here's a JavaScript function to format numbers to E.164:This function removes any non-digit characters and adds the country code if it's missing, ensuring a consistent E.164 format.
Database Schema Design
Choosing the right database schema is essential for efficient data management. Consider the following example SQL schema for storing San Marino phone numbers:
This schema includes fields for the phone number, type, validity, and timestamps. The
CHECK
constraint ensures that only valid San Marino numbers are stored, and theUNIQUE
constraint prevents duplicate entries. The index onphone_number
optimizes query performance.Error Handling
Proper error handling is crucial for robust application development. Anticipate potential issues and implement appropriate error handling mechanisms. Here's an example using Python:
This example demonstrates how to define custom exceptions for specific error scenarios and how to log errors for debugging and monitoring. Remember to handle exceptions gracefully and provide informative error messages to the user.
