Voice Call Compliance in Oman
A practical overview of the rules that affect voice call messaging and marketing in Oman, with a checklist before you launch.
Key Rules for Voice Calls in Oman
Automated and marketing calls to Omani numbers should be consent-based and limited to reasonable hours; we review TRA and operator requirements for each voice campaign before launch.
Telemarketing in the region is increasingly regulated, with rules on calling hours, registered numbers and do-not-call preferences in several countries.
Data Protection
Oman's Personal Data Protection Law (Royal Decree 6/2022) sets rules on consent, transparency and individuals' rights, which apply to website forms and marketing databases.
Keep a record of how each contact was collected, what they agreed to and when, and make it easy for them to withdraw consent.
Practical Checklist
- Check whether the call is promotional or a service call, as the rules differ.
- Use permitted calling numbers and caller ID, and never hide or spoof the calling number.
- Screen numbers against any national do-not-call register before promotional campaigns.
- Call only within permitted hours in the recipient's time zone and keep recorded messages short.
- Offer an easy way to stop further calls and record call consent where required.
Contact data
Format numbers in international E.164 format with the +968 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.
Timing and Language
Oman follows the Asia/Muscat time zone (UTC+04:00 in October 2026). The usual working week is Sunday to Thursday. Schedule voice call campaigns for the recipient's local daytime hours, avoid public holidays and religious observances that matter to your audience, and convert send times from IST before scheduling.
In Muscat, customers commonly use Arabic and English, with Hindi, Malayalam, Urdu and Balochi widely spoken. Messages in the customer's preferred language usually perform better, but check how local-language text affects character counts (for SMS) and template approval (for WhatsApp).
Digital Habits and Channels in Oman
Oman has high smartphone use, and WhatsApp is central to customer communication, while Instagram is popular for discovery. Business SMS sender IDs are registered with the licensed operators, Omantel, Ooredoo and Vodafone Oman, under the Telecommunications Regulatory Authority's rules.
Cards and cash are both common, and bank transfers are widely used for B2B. The weekend is Friday and Saturday. Ramadan, Eid, National Day in November and the Khareef monsoon season in Salalah from June to September shape demand.
Oman's economy depends on oil and gas, with the Oman Vision 2040 plan diversifying into logistics through the ports of Sohar, Duqm and Salalah, tourism, fisheries, mining and green hydrogen. VAT was introduced at 5% in April 2021, and prices are in Omani rials. The Personal Data Protection Law (Royal Decree 6/2022) came into force in February 2023, and its executive regulations require consent for processing personal data, including for marketing.
Regulators, Registers and Practical Rules in Oman
Oman's TRA regulates telecoms, and the Personal Data Protection Law has applied since February 2023.
Sender IDs are registered with operators. Arabic and English are both used. Omantel, Ooredoo and Vodafone Oman are the operators.
Oman's Telecommunications Regulatory Authority requires sender names for bulk SMS to be registered, and the Personal Data Protection Law (Royal Decree 6/2022) requires consent for marketing and gives people the right to object. Arabic is preferred for Omani nationals, with English and South Asian languages for expatriates. The weekend is Friday and Saturday, and Ramadan and the Khareef season in Dhofar change timing.
General guidance, not legal advice. Check current rules with the regulator or a local adviser before launch.
Advertising Alongside Messaging
Advertising should respect Omani law, cultural and religious norms and platform policies; health, financial and real estate promotions may need additional approvals.
This guide is general information, not legal advice, and reflects our understanding as of October 2026. Rules change, so we check current requirements for Oman before every launch.
