Quick Reference
Country: United Arab Emirates (UAE)
Country Code: +971
International Prefix: 00
National Prefix: 0
Number Structure and Validation
Before diving into implementation, let's establish a clear understanding of how UAE phone numbers are structured. This foundational knowledge will be crucial for building effective validation and formatting logic.
Core Number Components
Every UAE phone number consists of three essential parts:
Country Code: Always +971. This code identifies the country in international calls. You should always store and process numbers with the +971 prefix to ensure international compatibility.
Service Identifier: This part of the number indicates the type of service, such as mobile, landline, toll-free, premium rate, or shared cost. Recognizing the service identifier is crucial for routing calls correctly and applying appropriate validation rules.
Subscriber Number: This is the unique identifier for each subscriber within their respective service type. It's the core component that distinguishes one user from another.
Detailed Format Specifications
The following table outlines the specific formats for different types of UAE phone numbers:
Type
Format
Example
Validation Notes
Landline
+971 [2-9] [2-8]X{6}
+971 4 234 5678
Area codes 2-9 represent different emirates; the second digit must be 2-8.
Mobile
+971 5[024-68] X{7}
+971 50 123 4567
Only specific prefixes (50, 52, 54, 55, 56, 58) are valid.
Toll-Free
+971 800 X{2,9}
+971 800 123456789
Variable length after the 800 prefix.
Premium
+971 900 [02] X{5}
+971 900 020123
Must start with 900; limited to specific second digits (0 or 2).
Shared Cost
+971 700 [05] X{5}
+971 700 050123
Must start with 700; specific format requirements.
These formats are essential for validating user input and ensuring data integrity within your systems. Remember, incorrect formatting can lead to failed calls, misdirected messages, and frustrated users.
Now that you understand the structure, let's look at how to validate UAE phone numbers in your code. This example uses JavaScript, but the principles can be adapted to any language.
// Comprehensive UAE phone number validationconstvalidateUAEPhone=(phoneNumber)=>{// Remove spaces and any formatting. This ensures consistency regardless of user input.const cleaned = phoneNumber.replace(/\s+/g,'');// Validation patterns using regular expressions. These patterns encapsulate the format rules.const patterns ={landline:/^\+971[2-9][2-8]\d{6}$/,mobile:/^\+9715[024-68]\d{7}$/,tollFree:/^\+971800\d{2,9}$/,premium:/^\+971900[02]\d{5}$/,sharedCost:/^\+971700[05]\d{5}$/};// Check against each pattern. This iterates through the defined patterns to find a match.for(const[type, pattern]ofObject.entries(patterns)){if(pattern.test(cleaned)){return{isValid:true,type: type,formatted:formatUAEPhone(cleaned, type)// Call a formatting function (not shown here)};}}// If no match is found, the number is invalid.return{isValid:false,error:'Invalid UAE phone number format'};};// Example usage:console.log(validateUAEPhone('+971 50 123 4567'));// Valid mobile numberconsole.log(validateUAEPhone('+97142345678'));// Valid landline numberconsole.log(validateUAEPhone('+971 123 456 7890'));// Invalid number
This function provides a robust way to validate UAE phone numbers, ensuring that your application handles them correctly. You should integrate this validation into any part of your system that accepts phone number input.
Test Cases and Edge Cases:
Consider these scenarios:
Missing Country Code: If the input is "050 123 4567", the function will correctly identify it as invalid. You might want to prepend "+971" if the input starts with "0" to handle local number formats.
Incorrect Length: Inputs like "+971 50 123456" or "+971 50 12345678" will be flagged as invalid due to length mismatches.
Invalid Characters: Inputs containing non-numeric characters (e.g., "+971 50 123-4567") will be handled correctly by the replace function, but you might want to add specific error messages for such cases to provide better user feedback.
By considering these edge cases, you can make your validation even more robust and user-friendly.
Technical Implementation Best Practices
Building upon the validation example, let's explore some best practices for handling UAE phone numbers in your applications. These practices will help you create more robust and maintainable code.
Error Handling Scenarios
Effective error handling is crucial for any application. Here are some specific scenarios to consider when working with UAE phone numbers:
Invalid Format Detection: As shown in the previous example, you should always check for invalid formats. Provide clear and informative error messages to guide users towards correct input.
if(!phoneNumber.startsWith('+971')){thrownewError('UAE phone numbers must start with +971');}
Service Type Validation: In some cases, you might need to validate the service type (mobile, landline, etc.) based on the prefix. This can be achieved using a lookup table or a more sophisticated validation function.
constvalidateServiceType=(prefix)=>{const validPrefixes ={mobile:['50','52','54','55','56','58'],landline:['2','3','4','6','7','9']// Note: This is simplified for demonstration};// Check if the prefix exists in any of the valid prefix arraysfor(const type in validPrefixes){if(validPrefixes[type].includes(prefix)){return{isValid:true, type };}}return{isValid:false,error:'Invalid service type prefix'};};// Example usage:console.log(validateServiceType('50'));// Valid mobile prefixconsole.log(validateServiceType('4'));// Valid landline prefixconsole.log(validateServiceType('60'));// Invalid prefix
This function allows you to specifically validate the service type, providing more granular control over your phone number handling.
Number Portability Handling (MNP)
Mobile Number Portability (MNP) allows users to switch carriers while keeping their existing number. This can complicate validation, as a number's prefix might no longer correspond to its original carrier. To address this, consider the following:
Real-time Validation: The most accurate way to handle MNP is to query the TDRA's MNP database in real-time. This ensures you have the most up-to-date information about a number's carrier. However, be sure to handle potential timeouts and service unavailability gracefully. Caching query results with an appropriate Time-To-Live (TTL) can improve performance and reduce reliance on the external database.
Status Updates: If your application requires ongoing knowledge of a number's carrier, consider implementing a mechanism to monitor number status changes. Webhooks can be a useful tool for receiving updates from the TDRA. Maintaining audit logs of these changes is essential for compliance and troubleshooting.
By implementing these best practices, you can create a more robust and reliable system for handling UAE phone numbers. Remember to always prioritize data integrity, user experience, and regulatory compliance.
