  • SUR-CAD (Suriname Central Ambulance Service): 117 (as per the SUR-CAD website https://sur-cad.com/)

Including these numbers in your application can be a valuable safety feature for users. Remember to keep this list updated as numbers may change.

In summary, domestic calls in Suriname are straightforward due to the absence of area codes. You should ensure your system can differentiate between 6-digit landline numbers and 7-digit mobile numbers, using the leading digit of mobile numbers to identify the carrier.

International Communication

This section covers making and receiving international calls to and from Suriname.

Making International Calls

Follow these steps for international dialing:

  1. Dial the exit code: 00
  2. Country code: (This varies depending on the destination.)
  3. Area code (if applicable): Some countries require an area code.
  4. Local number: The recipient's local phone number.

Common international dialing patterns from Suriname:

USA/Canada: 00 1 XXX XXX XXXX
Netherlands: 00 31 XX XXX XXXX
Brazil: 00 55 XX XXXX XXXX

When implementing international dialing, you'll need to handle country codes and area codes correctly. A reliable database of country and area codes is essential for accurate routing.

Receiving International Calls

For incoming international calls to Suriname, use the following format:

Landline: +597 231234
Mobile: +597 7123456

The +597 prefix is the international country code for Suriname. You should ensure your system correctly handles the "+" prefix, potentially converting it to "00" for compatibility with certain systems. This is a crucial detail for seamless international communication. It's also important to note that Suriname has two submarine cable connections (Suriname-Guyana Submarine Cable System and Americas II), which contribute to its international connectivity, as mentioned in the additional context (https://www.budde.com.au/Research/Suriname-Telecoms-Mobile-and-Broadband-Statistics-and-Analyses).

To recap, international calling involves using the "00" exit code followed by the destination's country code, area code (if needed), and local number. For incoming calls, the "+597" country code precedes the local Suriname number.

Troubleshooting Guide

This section addresses common issues encountered when making calls to or from Suriname.

Common Issues and Solutions

Dialing Procedures and Implementation Guide

This section provides a practical guide for implementing Suriname phone number handling in your systems.

Understanding Domestic Calls

Suriname's domestic dialing system is designed for simplicity. All domestic calls follow a direct dialing approach. You'll find this straightforward structure easy to integrate into your applications.

Direct Dialing Patterns

  • Landline to Landline:

    Format: XXXXXX (6 digits)
Example: 231234

  • Landline to Mobile:

    Format: 7XXXXXX or 8XXXXXX (7 digits)
Example: 7123456

  • Mobile to Mobile:

    Format: 7XXXXXX or 8XXXXXX (7 digits)
Example: 8123456

Tip: When implementing dialing systems, always validate the number format before processing the call. This prevents errors and ensures smooth operation.

International Calling Framework

This subsection details the framework for handling international calls to and from Suriname.

Outbound International Calls

The international dialing format follows this structure:

00 + Country Code + Area Code (if required) + Local Number

Example Scenarios:

  • Calling USA: 00 1 212 555 0123
  • Calling Netherlands: 00 31 20 123 4567
  • Calling Brazil: 00 55 11 1234 5678

You should ensure your system can parse and process this format correctly.

Incoming International Calls

For calls to Suriname, use the following format:

+597 + Local Number

Warning: Remember to handle the "+" prefix appropriately in your implementation. Some systems may require converting it to "00" for proper routing. This is a critical detail for ensuring incoming international calls reach their destination.

Implementation Best Practices

This subsection outlines best practices for implementing Suriname phone number handling in your systems. You'll find these recommendations invaluable for building robust and reliable applications.

  1. Number Validation: Use regular expressions (regex) to validate number formats before processing. This prevents errors and ensures data integrity.

    // Landline validation
const landlineRegex = /^([234]\d{5})$/;

// Mobile validation
const mobileRegex = /^(7[1-9]\d{5}|8[1-9]\d{5})$/;

// Special services validation (including emergency numbers)
const specialServicesRegex = /^(1\d{2,4})$/;

  2. Format Standardization: Store numbers in E.164 format (+597XXXXXXX) for consistency and interoperability. This international standard simplifies number management and ensures compatibility with various systems.

    • Strip all formatting characters (spaces, hyphens, parentheses) before validation and storage.
    • Add formatting for display purposes only after retrieving the standardized E.164 format.

  3. Error Handling: Implement robust error handling to gracefully manage invalid number formats or other potential issues. This improves user experience and prevents unexpected application behavior.

    function validateSurinameNumber(number) {
  // Remove all non-digit characters except '+'
  const cleanNumber = number.replace(/[^\d+]/g, '');
  
  // Check if it's an international format
  if (cleanNumber.startsWith('+597')) {
    // Remove country code for local validation
    const localNumber = cleanNumber.substring(4);
    return validateLocalNumber(localNumber);
  }
  
  return validateLocalNumber(cleanNumber);
}

function validateLocalNumber(number) {
    if (landlineRegex.test(number)) return "landline";
    if (mobileRegex.test(number)) return "mobile";
    if (specialServicesRegex.test(number)) return "special";
    return "invalid"; // Return specific error codes for better debugging
}

    This example demonstrates how to handle both local and international number formats. You should adapt this code to your specific needs and integrate it into your validation workflow.

Common Implementation Challenges

This subsection discusses common challenges you might encounter during implementation and provides guidance on how to address them.

  1. Number Format Variations: Users might input numbers with spaces, hyphens, or other formatting characters. Your system should be able to handle these variations by stripping non-digit characters before validation.

  2. Legacy System Integration: Older systems might not support E.164 format. You might need to implement format conversion utilities to bridge the gap between legacy systems and modern standards.

  3. Handling Special Service Numbers: Special service numbers, including emergency numbers, often have different formats. Your system should be able to recognize and handle these numbers correctly. Consider using a separate regex for validating special service numbers.

At this point, you should have a clear understanding of how to implement Suriname phone number handling in your applications. Remember to validate number formats, standardize storage using E.164, and implement robust error handling to ensure smooth operation.

Note: For systems handling both domestic and international calls, implement separate validation logic for each case to ensure proper routing. This prevents conflicts and ensures accurate call processing. Also, be aware that some providers, like Digicel, have historically blocked VoIP calls, which might affect your application's functionality if it relies on VoIP services (as mentioned in the additional context).
