Mobile numbers follow the format [Operator Prefix][Subscriber Number], for example, 06-XXXXXXXX or 07-XXXXXXXX. You should be aware that some prefixes, like 06-8x, are shared between operators, requiring more nuanced validation.
Implementation Guidelines for Developers
This section provides practical guidance on implementing Western Sahara phone number handling in your systems. We'll cover validation, international formatting, and best practices.
1. Number Validation
Robust validation is crucial for ensuring data integrity and preventing errors. You should use regular expressions to validate number formats based on the prefixes and lengths outlined above.
// Example validation regex for Western Sahara mobile numbersconst mobileRegex =/^(?:06|07)[0-9]{8}$/;// More comprehensive regex incorporating operator-specific prefixesconst detailedMobileRegex =/^(?:06(?:[0-4]\d|5\d|6\d|7\d|8[0-247-9]|9\d)|07(?:0\d|1\d|2[0-4]\d|5[01]\d|6\d|7\d|8[0-3]\d))\d{6}$/;// Test the regexconsole.log(detailedMobileRegex.test('0612345678'));// trueconsole.log(detailedMobileRegex.test('0761234567'));// trueconsole.log(detailedMobileRegex.test('0683123456'));// false (06-83 to 06-86 are not allocated for mobile)console.log(detailedMobileRegex.test('0791234567'));// false (07-9x is not allocated for mobile)
Remember to test your regular expressions thoroughly with various valid and invalid inputs to ensure accuracy. Consider edge cases and potential formatting variations.
2. International Formatting
Converting local numbers to international format is essential for international calls and SMS messaging. You should adhere to the international E.164 standard.
// Convert local to international formatfunctiontoInternational(localNumber){return localNumber.replace(/^0/,'+212');}// Example usageconsole.log(toInternational('0612345678'));// +212612345678
This function replaces the leading '0' with the country code '+212'. This standardized format ensures compatibility with international telecommunications systems.
3. Number Preprocessing
Before validation, preprocess the input to handle variations in formatting. This step improves the reliability of your validation process.
functionpreprocessNumber(number){return number
.replace(/[\s\-\(\)\.]/g,'')// Remove whitespace, hyphens, parentheses, and periods.replace(/^(\+212|00212)/,'')// Remove leading country code (if present).replace(/^0/,'');// Remove leading national prefix (if present)}// Example usageconsole.log(preprocessNumber('+212 612 345 678'));// 612345678console.log(preprocessNumber('0612-345-678'));// 612345678
This function removes common formatting characters and leading prefixes, preparing the number for validation against your defined patterns.
4. Comprehensive Validation Function
Combine preprocessing and regex validation into a single function for streamlined validation.
const patterns ={landline:/^528[89]\d{5}$/,mobile:/^(?:6[0-79]|68[0-247-9]|7[0167]|72[0-4]|75[01]|78[0-3])\d{7}$/,tollFree:/^80[0-7]\d{6}$/,premiumRate:/^89\d{7}$/};functionvalidateWesternSaharaNumber(number, type ='any'){const cleaned =preprocessNumber(number);if(type ==='any'){returnObject.values(patterns).some(pattern=> pattern.test(cleaned));}return patterns[type]&& patterns[type].test(cleaned);}// Example usageconsole.log(validateWesternSaharaNumber('+212528812345','landline'));// trueconsole.log(validateWesternSaharaNumber('0612345678','mobile'));// trueconsole.log(validateWesternSaharaNumber('800123456','tollFree'));// trueconsole.log(validateWesternSaharaNumber('0683123456','mobile'));// false
This function allows you to validate against specific number types or check for any valid format. It incorporates the preprocessing step for improved reliability.
5. Error Handling and User Feedback
Provide clear and informative error messages to guide users. Consider supporting multiple languages.
const errorMessages ={en:{invalidFormat:'Invalid phone number format',// ... other error messages},// ... other languages};// Example usage within a validation functionfunctionvalidateAndProvideFeedback(number, type){if(!validateWesternSaharaNumber(number, type)){console.error(errorMessages.en.invalidFormat);returnfalse;}returntrue;}
This approach enhances user experience by providing specific feedback on validation failures.
6. Best Practices
Input Handling: Accept multiple input formats for user convenience. Provide clear validation feedback in real-time.
Performance Optimization: Cache compiled regular expressions and validation results to improve performance.
Testing Strategy: Implement comprehensive testing with various test cases, including edge cases and invalid inputs.
