How to Send SMS in Armenia: 2025 Guide to Regulations, APIs & Compliance

Sending SMS in Armenia requires understanding local telecommunications regulations, carrier-specific requirements, and proper technical implementation. This guide covers everything you need to send SMS messages to Armenian mobile networks, including alphanumeric sender ID registration with Armenian mobile operators (Viva, Team, Ucom), Public Services Regulatory Commission (PSRC) compliance requirements, SMS API integration with major providers (Twilio, Sinch, MessageBird, Plivo), and delivery best practices to maximize message reach across Armenia's telecommunications infrastructure. For phone number formatting requirements, see our E.164 format guide.

Armenia SMS Market Overview: Mobile Operators & Network Infrastructure

Market Conditions: Armenia has a well-developed mobile telecommunications market with three major operators: Viva (formerly Viva-MTS/VivaCell-MTS), Team (formerly Beeline/Team Telecom Armenia), and Ucom. As of Q4 2023, Viva commands 57% of mobile subscriptions, Team holds 25.6%, and Ucom accounts for 17% of the market. In 2024, the Armenian government acquired a 20% ownership stake in Viva as a donation from the new owner. The telecom market is expected to reach USD 255.60 million in 2025, growing at a CAGR of 5.24% to USD 330 million by 2030.

SMS remains an important communication channel for business messaging, particularly for transactional notifications, two-factor authentication (2FA), one-time passwords (OTP), and marketing campaigns, though messaging apps like Viber and Telegram are increasingly popular among consumers. On June 12, 2025, Ucom launched Armenia's largest 5G network at a public celebration event, covering 35 regional cities, 19 settlements, Myler Mountain Resort, border customs checkpoints (Bagratashen, Bavra, and Agarak), and the Yerevan-Dilijan highway – reaching 65% of the population. Built in partnership with Nokia using non-standalone architecture (Release 15, 3GPP) that integrates with existing 4G infrastructure, the deployment positions Ucom as the technological leader in Armenia's mobile market. Team Telecom won 5G frequency tenders in May 2023 with a requirement to launch 5G services in Yerevan, Gyumri, and Vanadzor within two years. Android devices dominate the mobile operating system landscape in Armenia.

What SMS Features Are Supported in Armenia?

Armenia supports standard SMS messaging features with some limitations, offering concatenated messaging and alphanumeric sender IDs, though two-way SMS functionality is not available.

Does Armenia Support Two-Way SMS?

Two-way SMS is not supported in Armenia through major SMS providers. This means you cannot receive replies to your SMS messages through standard A2P channels.

How Long Can My SMS Messages Be in Armenia? (Concatenated Messages)

Support: Yes, concatenated messaging is fully supported in Armenia.

Message length rules:

• Single SMS with GSM-7 encoding: 160 characters maximum
• Single SMS with UCS-2 encoding: 70 characters maximum
• Multi-segment with GSM-7: 153 characters per segment (reduced due to reassembly header)
• Multi-segment with UCS-2: 67 characters per segment (reduced due to reassembly header)

Encoding considerations:

• GSM-7 uses 7 bits per character and supports standard Latin characters, numbers, and basic symbols
• UCS-2 uses 16 bits (2 bytes) per character and triggers automatically when messages contain non-GSM-7 characters such as emoji, curly quotes (" "), or scripts like Armenian, Chinese, or Arabic
• Even a single non-GSM-7 character will force the entire message to use UCS-2 encoding, reducing the character limit from 160 to 70
• Use GSM-7 for standard Latin characters to maximize message length
• Learn more about character encoding standards and GSM-7 vs UCS-2 differences to optimize message length across different languages

Can I Send MMS Messages in Armenia?

MMS messages are not directly supported in Armenia. When you attempt to send MMS, the message converts automatically to SMS with an embedded URL link where recipients can view the multimedia content. This ensures message delivery while maintaining compatibility with all mobile devices.

Mobile Number Portability & Landline Compatibility

How Does Number Portability Work in Armenia?

Mobile Number Portability (MNP) launched in Armenia in April 2014 by the Public Services Regulatory Commission (PSRC). The service allows users to keep their phone numbers when switching between mobile operators, transferring within three working days at no charge. Users can transfer their mobile number up to two times in any 12-month period.

Impact on SMS delivery: Number portability does not significantly impact SMS delivery or routing, as messages route automatically to the correct carrier. However, you cannot reliably determine a mobile operator solely based on the number prefix – subscribers can switch operators while retaining their numbers, making prefix-based identification inaccurate.

Can You Send SMS to Landlines in Armenia?

You cannot send SMS to landline numbers in Armenia. Attempts to send messages to landline numbers will result in delivery failure, typically generating a 400 response with error code 21614. These messages will not appear in logs, and we will not charge your account for failed delivery attempts.

Armenia SMS Regulations: PSRC Compliance & Legal Requirements

Armenia's telecommunications sector is regulated by the Public Services Regulatory Commission (PSRC), established under the Law on Electronic Communication (adopted 2005). The PSRC grants licenses to operators, monitors the radio frequency spectrum, and sets regulations and standards for electronic communications. In 2024, the PSRC implemented new reporting requirements mandating that all mobile operators submit data based on active subscribers, including metrics on revenue, costs, ARPU (average revenue per user), MOU (average monthly usage per subscriber), and APPM (weighted average price per minute). While specific SMS marketing laws are less stringent compared to other European countries, follow international best practices for responsible messaging.

SMS Marketing Consent Requirements in Armenia

While Armenia doesn't have explicit opt-in requirements for SMS marketing, obtain and document consent:

• Obtain and document explicit consent before sending marketing messages
• Maintain clear records of how and when you obtained consent
• Provide transparent information about message frequency and content type
• Include clear terms and conditions during the opt-in process
• Follow GDPR-style consent practices for international compliance standards

HELP/STOP Commands & Opt-Out Management

While not legally mandated in Armenia, implement HELP/STOP functionality as an SMS best practice:

• Support both Armenian and English keywords for opt-out commands
• Common Armenian opt-out keywords include "ՍՏՈՊ" (STOP) and "ՕԳՆՈՒԹՅՈՒՆ" (HELP)
• Process opt-out requests within 24 hours
• Send confirmation messages in the user's preferred language
• Maintain an unsubscribe database to prevent future messages

Do Not Call / Do Not Disturb Registries

Armenia does not maintain an official Do Not Disturb (DND) registry for SMS messaging. However, you should:

• Maintain your own suppression lists
• Honor opt-out requests immediately
• Keep records of opted-out numbers for at least 12 months
• Regularly clean contact lists to remove inactive or opted-out numbers

Best Times to Send SMS in Armenia (Time Zone & Messaging Hours)

Armenia observes Armenia Time (AMT) at UTC+4 year-round with no daylight saving time. While there are no legal restrictions on messaging hours:

• Recommended sending window: 9:00 AM to 8:00 PM AMT (UTC+4)
• Avoid sending messages on major Armenian holidays
• Reserve after-hours messaging for urgent notifications only

How to Register an Alphanumeric Sender ID in Armenia

Alphanumeric Sender ID Registration Process

Operator network capability: Supported with pre-registration

Registration requirements: Pre-registration required, typically taking 3 weeks for approval. Submit: (1) Sender ID (3–11 characters), (2) SMS type (OTP or Marketing), (3) SMS content with URL links

Sender ID preservation: Yes, preserved when properly registered. Without registration, your sender ID will be overwritten to a generic alphanumeric ID or rejected.

Best practices:

• Limited to 11 characters (minimum 3 characters)
• Allowed characters: a-z, A-Z, 0-9, and a single space
• Must not impersonate other brands
• Cannot contain special characters beyond a single space
• Work with your SMS provider to initiate the registration process
• Registration requirements vary by country – if you're sending SMS to neighboring regions, review guidelines for Georgia SMS or Azerbaijan SMS

Long Codes for SMS in Armenia

Domestic vs. International: International long codes supported; domestic long codes not available

Sender ID preservation: No, sender IDs may be overwritten by carriers

Provisioning time: Immediate for international long codes

Use cases:

• Transactional messages

Frequently Asked Questions About Sending SMS in Armenia

How long does it take to register an alphanumeric sender ID in Armenia?

Alphanumeric sender ID registration in Armenia typically takes 3 weeks for approval. You'll need to submit your sender ID (3–11 characters), specify the SMS type (OTP or Marketing), and provide sample SMS content with any URL links. Work with your SMS provider to initiate the registration process with Armenian carriers. Pre-registration is mandatory for all three carriers (Viva, Team, Ucom) – unregistered sender IDs will be overwritten or rejected.

Which mobile operators support SMS in Armenia?

Armenia has three major mobile operators that support SMS: Viva (57% market share), Team (25.6% market share), and Ucom (17% market share). All three carriers support A2P SMS messaging with proper sender ID registration. Test your messages across all carriers to ensure optimal delivery rates.

Can I send two-way SMS in Armenia?

No, two-way SMS (also called bidirectional SMS or SMS replies) is not supported in Armenia through major A2P SMS providers. You cannot receive replies to your outbound SMS messages through standard A2P messaging channels. For interactive customer communications, consider alternative solutions such as web forms, mobile apps, or OTT messaging platforms like WhatsApp Business or Telegram.

What phone number format should I use for SMS in Armenia?

Use E.164 international format for all Armenian phone numbers when sending SMS: +374 followed by the 8-digit subscriber number. Armenia's country code is +374, and the mobile country code (MCC) is 283. Ensure your SMS API integration properly validates and formats numbers in E.164 format before sending to avoid delivery failures and rejected messages.

E.164 format examples:

• Correct: +37412345678
• Incorrect: 37412345678 (missing + prefix)
• Incorrect: 012345678 (missing country code)

Learn more about E.164 international phone number formatting standards to ensure proper formatting across all countries in your SMS campaigns.

Are there restrictions on SMS content in Armenia?

Yes, Armenian mobile carriers restrict certain SMS content types including gambling and betting services, political campaign messages, adult or pornographic content, religious content, and illegal drugs or controlled substances. Additionally, carrier content filtering systems may automatically block messages containing suspicious URLs, excessive punctuation, all-caps text, or spam keywords. To avoid message filtering, use pre-registered alphanumeric sender IDs consistently, avoid URL shorteners, and maintain steady sending volumes.

What are the best times to send SMS in Armenia?

While Armenia has no legal restrictions on SMS sending hours, follow best practices by sending marketing SMS between 9:00 AM and 8:00 PM Armenia Time (AMT, UTC+4). Armenia observes UTC+4 year-round with no daylight saving time changes. Avoid sending promotional messages during major Armenian holidays such as New Year, Armenian Christmas (January 6), and Republic Day (May 28). Reserve after-hours messaging exclusively for urgent transactional notifications like OTP codes, delivery alerts, or security notifications.

What SMS gateway providers work best in Armenia?

The most reliable SMS gateway providers for Armenia include Twilio, Sinch, MessageBird, and Plivo. All four providers support alphanumeric sender ID registration, E.164 phone number formatting, and delivery receipt (DLR) tracking for Armenian mobile networks. Choose your provider based on volume requirements, API features, pricing structure, and customer support availability. For high-volume A2P messaging campaigns, consider providers with dedicated account management and optimized routing to Viva, Team, and Ucom networks.
