Frequently Asked Questions
Algerian phone numbers use a 10-digit closed numbering plan, including both landlines and mobile phones. When calling from outside Algeria, the country code +213 must be used before the 10-digit number. For domestic calls within Algeria, a leading "0" is often used before the area code or mobile prefix.
Use regular expressions (regex) to validate Algerian phone numbers, ensuring data integrity and preventing errors. Different regex patterns are used for geographic, mobile, toll-free, premium, and shared-cost numbers. You'll need a comprehensive list of area codes from a reliable source like the Algerian Regulatory Authority for Post and Telecommunications (ARPT/ARPCE).
Format Algerian phone numbers consistently for better user experience, using appropriate spacing and including the country code (+213) for international format. For national format within Algeria, include the leading "0" before the area/mobile prefix.
+213 is the internationally recognized country code assigned to Algeria. All calls made to Algeria from other countries must use this prefix. Domestic calls often use "0" followed by the full 10-digit number
The area code for Algiers is 21. It follows the +213 country code, so a full number from Algiers would look like +213 21 XXXXXXX, where the X's represent the subscriber's unique number.
The "0" prefix is used for domestic calls within Algeria but should be omitted when making international calls to Algeria. Failing to add or remove the "0" can prevent the call from connecting.
Algeria has three primary mobile network operators: Mobilis (state-owned), Djezzy, and Ooredoo. Each operator has its own set of prefixes used to identify their numbers.
Dial +213 followed by the mobile prefix (e.g., 5, 6, or 7) and then the 7-digit subscriber number. Ensure the leading "0" is not included when calling from abroad.
Yes, storing Algerian phone numbers in E.164 format (+213XXXXXXXXX) is recommended for consistency, database management, and international compatibility. This format ensures efficient handling of numbers for various applications.
Adhere to the regulations set by the Autorité de Régulation des Communications Electroniques et des Postes (ARPCE), formerly ARPT. This includes accurate number formatting, proper prefix usage, and compliance with number allocation rules.
To call internationally from Algeria, use the international access code "00" followed by the country code and then the subscriber's number. For example, to call the US, dial 00 1 [US Number].
Toll-free numbers in Algeria follow the format +213 800 XXXXXXX. They are free to call from within Algeria and offer a convenient way for customers to contact businesses or services nationwide.
Common errors include incorrect use of the "0" prefix, using outdated or incomplete area codes, and inconsistent number formatting, all of which can cause issues when making calls or storing numbers.
The Autorité de Régulation des Communications Electroniques et des Postes (ARPCE) is responsible for regulating Algeria's telecommunications sector. They maintain the standards and guidelines for number formats, prefixes, and other related aspects.

Algeria Phone Numbers: Format, Area Code & Validation Guide
This guide provides a comprehensive overview of Algeria's telephone numbering system, designed for developers, telecommunications professionals, and anyone integrating Algerian phone numbers into their applications. We'll cover number formatting, validation, best practices, and regulatory considerations to ensure accurate and compliant handling of Algerian phone numbers.
Number Structure and Formatting
Algeria uses a 10-digit closed numbering plan for both landlines and mobile phones. All numbers are dialed with the country code +213 when calling from outside Algeria.
10-Digit System Breakdown
The two or three digits after the country code represent the area code for landlines or the operator prefix for mobile numbers. The remaining seven digits are the subscriber's unique number.
Number Formats by Type
+213 [Area] [Local]
+213 [Prefix] [Number]
+213 800 [Number]
+213 80[3-6] [Number]
+213 80[1-2] [Number]
Implementation Guide
Correct implementation is crucial for seamless communication. Here's a guide to validating and formatting Algerian phone numbers:
Validation Patterns
Robust validation prevents errors and ensures data integrity. Use these regular expressions (regex) for validation:
Important Note: The provided geographic regex is illustrative and needs to be expanded to include all valid Algerian area codes for comprehensive validation. Refer to a regularly updated list of area codes from a reliable source like the Algerian Regulatory Authority for Post and Telecommunications (ARPT/ARPCE).
Formatting Examples
Consistent formatting improves readability and user experience.
