Voice Call Compliance in Bangladesh
A practical overview of the rules that affect voice call messaging and marketing in Bangladesh, with a checklist before you launch.
Key Rules for Voice Calls in Bangladesh
Voice broadcasting in Bangladesh runs through BTRC-licensed operators and providers; campaigns should be consent-based and scheduled at reasonable hours.
Voice campaigns should use locally permitted numbers and respect the regulator's rules on unsolicited calls.
Data Protection
Bangladesh is still putting comprehensive personal data protection rules in place, so we follow international best practice: clear notices, consent for marketing and secure handling of customer data.
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 +880 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.
Timing and Language
Bangladesh follows the Asia/Dhaka time zone (UTC+06:00 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 Dhaka, customers commonly use Bangla (Bengali) and English. 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 Bangladesh
Bangladesh is a mobile-first market where Facebook, Messenger and WhatsApp play a huge role in discovery and commerce, and many small businesses sell directly through Facebook pages. Bulk SMS is widely used for promotions and OTPs through licensed providers under BTRC rules.
bKash and Nagad mobile financial services are used by tens of millions of people, and cash on delivery is common. Eid al-Fitr and Eid al-Adha are the biggest shopping periods, and Pohela Boishakh (Bengali New Year) in April is another key moment.
Bangladesh is one of the world's largest garment exporters, and its economy also relies on remittances, agriculture, pharmaceuticals and a growing IT outsourcing sector. VAT is generally 15%, and prices are in taka. The Bangladesh Telecommunication Regulatory Commission (BTRC) licenses operators and bulk SMS providers, and Bangla is the main language for consumer marketing, with English for B2B.
Regulators, Registers and Practical Rules in Bangladesh
Bangladesh's BTRC regulates telecoms and approves masked (alphanumeric) sender names for bulk SMS.
Messages should be in Bangla, with English for B2B. bKash and Nagad are widely used for payments. Eid and Pohela Boishakh are peak periods.
BTRC also sets rules for bulk SMS gateways and short codes. Grameenphone, Robi, Banglalink and Teletalk are the operators. WhatsApp, Messenger and IMO are all widely used.
In practice, Bangla messages in Unicode use more SMS parts, so keep them short.
General guidance, not legal advice. Check current rules with the regulator or a local adviser before launch.

Advertising should follow Bangladeshi consumer rights law and platform policies, with sensitivity to cultural and religious norms.
