Ivory Coast SMS Guide: Compliance, Sender IDs & Best Practices

Send SMS in Ivory Coast (Côte d'Ivoire) by understanding local regulations, operator requirements, and technical specifications. This complete guide covers everything you need to know about SMS in Ivory Coast: ARTCI compliance requirements, sender ID registration process (3 weeks), phone number formats, operator integration with Orange, MTN, and Moov networks, and best practices for transactional messages, marketing campaigns, and two-factor authentication. Whether you're launching your first SMS campaign or scaling existing operations, this guide provides actionable steps for reliable SMS delivery in Ivory Coast.

Ivory Coast SMS Market Overview: Mobile Operators and Network Coverage

Market Conditions: Three major operators dominate Ivory Coast's mobile market: Orange (prefix 07), MTN (prefix 05), and Moov/Atlantic Telecom (prefix 01). Orange holds approximately 45% market share, while MTN Côte d'Ivoire leads in total mobile subscriptions as of 2023. Network coverage has expanded significantly – 2G/3G covers over 92.9% of the territory and 4G covers approximately 63.7% as of 2024 (source: ARTCI). Orange operates the highest-quality 4G/5G network in the country.

Market Penetration: As of Q4 2024, mobile penetration exceeds 150% (multiple SIM ownership), with over 48 million active connections serving a population of approximately 30 million. SMS usage remains strong for business-to-consumer communications despite OTT messaging growth in urban areas. Transactional SMS and authentication services drive 70% of business messaging volume.

On 31 January 2021, the country transitioned from 8-digit to 10-digit phone numbers by prepending two digits based on carrier (source: ITU Operational Bulletin No. 1266, 24.XII.2020). This change addressed mobile number resource saturation and ensures availability for growing demand.

Recent Infrastructure Developments: In late 2024 and early 2025, all three operators (Orange, MTN, and Moov Africa) committed to deploying approximately 240 small-scale radio sites nationwide to improve coverage across underserved areas.

Phone Number Format: Use 10-digit numbers in these formats:

• Within Côte d'Ivoire: XX XX XXX XXX
• International format: +225 XX XX XXX XXX

Mobile Operator Prefixes (effective 31 January 2021):

• 01: Moov/Atlantic Telecom (formerly Etisalat)
• 05: MTN Côte d'Ivoire
• 07: Orange Côte d'Ivoire
• Note: 8-digit numbers are obsolete. Use the 10-digit format with carrier prefix.

SMS Features and Technical Capabilities in Ivory Coast

Ivory Coast supports concatenated messaging and alphanumeric sender IDs, but does not support two-way SMS.

Does Ivory Coast Support Two-Way SMS?

Two-way SMS is not supported in Ivory Coast. Design your SMS strategies around one-way communication flows.

Alternative for Two-Way Communication: Use USSD (Unstructured Supplementary Service Data) codes for interactive sessions. USSD enables real-time two-way communication through session-based menus. Contact your SMS provider or mobile operators directly to provision USSD short codes for interactive services like balance inquiries, surveys, or customer service menus.

Concatenated Messages (Segmented SMS)

Support: Yes – concatenation works for messages exceeding standard length limits, though support varies by sender ID type.

Message Length Rules:

• 160 characters for GSM-7 encoding
• 70 characters for UCS-2 encoding

Concatenation Example: A 320-character message automatically splits into three segments:

• Segment 1: 153 characters (7 characters reserved for concatenation header)
• Segment 2: 153 characters
• Segment 3: 14 characters (remaining content)
• Total cost: 3 message segments

Each segment is billed separately. Messages exceeding 160 characters use 153-character segments to accommodate concatenation headers.

Encoding Considerations: Both GSM-7 and UCS-2 encoding are supported. Use UCS-2 for messages containing special characters or non-Latin alphabets.

MMS Support

MMS messages automatically convert to SMS with an embedded URL to access multimedia content. This ensures compatibility across all devices while enabling rich media sharing.

MMS-to-SMS Conversion Details:

• Pricing: MMS conversion costs 2–3 SMS segments plus standard SMS delivery fees
• URL Requirements: Use your own domain or your provider's whitelisted domain for media hosting
• Expiration: Media URLs typically remain active for 30 days
• Best practice: Notify recipients that they'll receive a link to view multimedia content

Recipient Phone Number Compatibility

Number Portability

Number portability is not available in Ivory Coast. Mobile numbers remain tied to their original network operators, simplifying message routing.

Carrier Identification: Determine the carrier from the phone prefix for routing optimization:

• 01: Route to Moov/Atlantic Telecom
• 05: Route to MTN Côte d'Ivoire
• 07: Route to Orange Côte d'Ivoire

This enables carrier-specific optimization, including tailored delivery settings, carrier-specific rate negotiation, and targeted retry logic.

Sending SMS to Landlines

SMS to landline numbers is not supported. Attempts to send messages to landlines result in a 400 response error (code 21614) through the REST API, with no message delivery and no charges to your account.

SMS Compliance and ARTCI Regulatory Requirements in Ivory Coast

The Autorité de Régulation des Télécommunications/TIC de Côte d'Ivoire (ARTCI) regulates SMS communications in Ivory Coast. Key regulatory frameworks include Law No. 2024-352 (June 6, 2024) relating to electronic communications, which updates the telecommunications regulatory framework, and Law No. 2013-450 on personal data protection. Recent ARTCI Decision n°2024-1194 (December 30, 2024) established SMS termination tariff ceilings for 2025-2027.

Enforcement and Penalties: While ARTCI has not published a comprehensive public registry of penalties, enforcement actions typically include suspension of sender IDs (immediate), fines ranging from 5 million to 50 million XOF ($8,000–$80,000 USD) for serious violations, and potential criminal liability for personal data protection violations under Law No. 2013-450. Repeat offenders face service provider blacklisting across all carriers.

Data Privacy and Personal Data Protection

Legal Framework: Law No. 2013-450 governs personal data protection in Côte d'Ivoire, enforced by ARTCI. This law aligns with the ECOWAS Supplementary Act A/SA.1/01/10 on Personal Data Protection (2010) and protects fundamental rights regarding personal data processing.

Key Data Protection Requirements:

• Obtain explicit consent before collecting or processing personal data for SMS campaigns
• Provide individuals the right to access, correct, supplement, update, or delete their personal data
• Honor requests to object to data processing for prospecting (marketing) purposes
• Maintain secure data processing practices and document compliance measures
• Ensure lawful data transfers if sharing recipient data across borders

Data Protection Compliance Checklist:

• Obtain and document explicit consent with timestamp and source
• Implement secure data storage with encryption at rest and in transit
• Establish data retention policy (recommend maximum 24 months for marketing lists)
• Create process for data subject access requests (respond within 30 days)
• Document lawful basis for processing under Law No. 2013-450
• Implement data breach notification procedures (notify ARTCI within 72 hours)
• Conduct annual data protection compliance audits
• Appoint data protection officer if processing over 100,000 records

Compliance Note: In December 2023, ARTCI announced a study on the impact of advanced technologies on personal data protection, indicating ongoing regulatory evolution in this area.

Consent and Opt-In Requirements

Explicit Consent Requirements:

• Obtain written or electronic consent before sending marketing messages
• Maintain detailed records of when and how you obtained consent, including timestamp and source
• Clearly communicate the purpose and frequency of messages during opt-in
• Document the scope of consent for compliance with Law No. 2013-450

Best Practices for Consent Collection:

• Use double opt-in processes for marketing lists
• Provide clear terms and conditions during signup
• Document consent timestamp, source, and scope
• Enable easy opt-out methods at signup

Consent Form Template:

HELP/STOP Commands

• Support standard STOP commands in all SMS campaigns
• Recognize HELP and STOP keywords in both French and English
• Common French keywords: ARRETER, STOP, DESABONNER
• Respond to HELP/STOP commands immediately and free of charge

Automated HELP/STOP Processing:

// Implement keyword detection and automated responses
function processInboundKeyword(message: string, sender: string): string {
  const normalized = message.trim().toUpperCase();

  // STOP/opt-out keywords
  if (['STOP', 'ARRETER', 'DESABONNER', 'UNSUBSCRIBE'].includes(normalized)) {
    removeFromList(sender); // Remove from database
    return "Vous êtes désabonné. You have been unsubscribed.";
  }

  // HELP keywords
  if (['HELP', 'AIDE', 'INFO'].includes(normalized)) {
    return "Pour se désabonner, répondez STOP. To unsubscribe, reply STOP. Support: [contact]";
  }

  return null; // No keyword matched
}

Do Not Call / Do Not Disturb Registries

Ivory Coast does not maintain an official Do Not Call registry. Follow these practices:

• Maintain your own suppression lists
• Honor opt-out requests within 24 hours
• Keep records of opted-out numbers for at least 12 months
• Regularly clean contact lists to remove unsubscribed numbers

Sending Time Restrictions and Frequency Limits

Time Restrictions:

• Avoid sending messages between 10 PM and 6 AM local time (Africa/Abidjan, GMT+0)
• Limit messages to 3 per subscriber per day
• Exception: Send emergency or explicitly requested messages outside these hours

Time Zone Handling for Automated Campaigns:

import { DateTime } from 'luxon';

function canSendMessage(recipientTimezone: string = 'Africa/Abidjan'): boolean {
  const now = DateTime.now().setZone(recipientTimezone);
  const hour = now.hour;

  // Allow sending between 6 AM and 10 PM local time
  return hour >= 6 && hour < 22;
}

These carrier limits apply regardless of provider API limits. Distribute high-volume campaigns across multiple sender IDs or use throttling to respect carrier constraints.

Throughput Management:

// Example rate limiting implementation
import { RateLimiter } from 'limiter';

const limiter = new RateLimiter({
  tokensPerInterval: 100,
  interval: 'second'
});

async function sendBulkSMS(messages: Array<{to: string, body: string}>) {
  const results = [];

  for (const msg of messages) {
    await limiter.removeTokens(1);
    try {
      const result = await sendSMSToIvoryCoast(msg.to, msg.body, 'YOUR_SENDER_ID');
      results.push(result);
    } catch (error) {
      console.error(`Failed to send to ${msg.to}:`, error);
      results.push({ error, to: msg.to });
    }
  }

  return results;
}

Error Handling and Logging

Common Error Scenarios:

• Invalid phone number format
• Unregistered sender ID

  segmentCount?: number;
}

async function logSMSActivity(log: SMSLog): Promise<void> {
  // Add carrier information
  log.carrier = getCarrier(log.recipient);

  console.log(JSON.stringify(log, null, 2));

  // Store in database with retention policy
  await db.smsLogs.insert({
    ...log,
    expiresAt: new Date(Date.now() + 90 * 24 * 60 * 60 * 1000) // 90-day retention
  });
}

Frequently Asked Questions: Sending SMS in Ivory Coast

What phone number format should I use for sending SMS in Ivory Coast?

Use the international E.164 format: +225 XX XX XXX XXX. Ivory Coast transitioned to 10-digit numbers on 31 January 2021 (source: ITU Operational Bulletin No. 1266). The first two digits identify the mobile operator: 01 for Moov/Atlantic Telecom, 05 for MTN, and 07 for Orange. Always include the +225 country code when sending international SMS to ensure proper routing.

Do I need to register my sender ID in Ivory Coast?

Yes, alphanumeric sender ID registration is mandatory in Ivory Coast and takes approximately 3 weeks. Dynamic sender IDs are not allowed. Pre-register through your SMS provider before launching campaigns. Provide your desired sender ID (maximum 11 characters), sample message content, and full URLs (no shortened links). Generic sender IDs like "INFO" or "Verify" are prohibited, as are major brand names like "Google."

What are the SMS compliance requirements in Ivory Coast?

Ivory Coast SMS compliance requires: (1) explicit consent under Law No. 2013-450 before sending marketing messages, (2) support for STOP commands in French (ARRETER, DESABONNER) and English, (3) honoring opt-outs within 24 hours, (4) avoiding sending between 10 PM and 6 AM, and (5) limiting messages to 3 per subscriber per day. ARTCI enforces these regulations, with recent updates in Law No. 2024-352 (June 2024).

Which mobile operators work in Ivory Coast?

Three major mobile operators work in Ivory Coast: Orange Côte d'Ivoire (prefix 07, ~45% market share), MTN Côte d'Ivoire (prefix 05, leading in subscriptions), and Moov Africa/Atlantic Telecom (prefix 01). As of 2024, network coverage reaches 92.9% for 2G/3G and 63.7% for 4G (source: ARTCI). Number portability is not available, so phone numbers remain tied to their original operator, which simplifies routing.

Can I send two-way SMS in Ivory Coast?

No, two-way SMS is not currently supported in Ivory Coast. You cannot receive replies to SMS messages sent through standard SMS channels. Design your SMS strategies around one-way communication flows only. For applications requiring user responses, consider alternative solutions like web forms, USSD codes, or dedicated mobile apps.

How long does sender ID registration take in Ivory Coast?

Alphanumeric sender ID registration in Ivory Coast takes approximately 3 weeks for approval. Short code provisioning requires 8–12 weeks for approval and setup. Plan your launch timeline accordingly and submit registration requests well in advance of campaign start dates. Registration requirements include sample content, URL verification, and compliance checks by local carriers.

What message length limits apply in Ivory Coast?

Ivory Coast follows standard SMS length limits: 160 characters per message segment for GSM-7 encoding (Latin alphabet), and 70 characters per segment for UCS-2 encoding (special characters, emojis, non-Latin scripts). Concatenated messages are supported, allowing longer content to be split across multiple segments. Each segment is billed separately, so optimize message length to minimize costs while maintaining clarity.

How much does it cost to send SMS in Ivory Coast?

SMS pricing in Ivory Coast varies by provider, operator, and message volume. Typical costs range from $0.03 to $0.08 per message segment. Costs differ between Orange, MTN, and Moov networks. Alphanumeric sender IDs may incur higher rates than numeric long codes. Bulk volume discounts are available from most SMS providers. Contact your SMS gateway provider for current pricing specific to your use case and volume commitments.

Cost Comparison by Carrier and Message Type:

Note: Pricing varies by provider contracts and volume commitments. Request provider-specific quotes for accurate pricing.

What content is restricted for SMS in Ivory Coast?

Restricted content in Ivory Coast includes: gambling and betting promotions, adult content, cryptocurrency promotions, political messaging without authorization, religious content (subject to carrier filtering), and unsolicited promotional messages. Carriers actively filter messages containing prohibited keywords. Avoid shortened URLs, excessive punctuation, and all-caps text. Test messages across all three operators before launching campaigns to ensure deliverability.
