To reach customers across DR Congo by SMS you need routes to all four networks, Vodacom, Airtel, Orange and Africell, a registered sender ID, and messages written for the city you are sending to: Lingala in Kinshasa, Swahili in the east, French everywhere. Personal data falls under the 2023 Digital Code, and telecoms are regulated by the ARPTC, which is in transition to a new authority, the ARPTIC.
Last reviewed: 28 October 2026. This article summarises public rules and is not legal advice. Check edge cases with the regulator.
Our short bulk SMS overview for DR Congo covers the basics. This guide is for teams planning a national rollout: who regulates what, how consent works under the Digital Code, language choices by region, dollar versus franc pricing in messages, and a checklist.

Who regulates SMS: ARPTC and ARPTIC
The 2020 law on telecommunications and information and communication technologies replaced the 2002 framework law and provided for a new regulator, the Autorite de Regulation des Postes, des Telecommunications et des TIC (ARPTIC). Its founding decree was published in March 2023, and a ministerial order has given it the functions of the planned digital regulator, the electronic certification authority and the data protection authority. Until the new body is fully installed, transitional arrangements apply and the ARPTC continues to operate; news reports in 2026 still refer to its president.
For a sender, the practical effect is limited: operators apply the regulator's requirements on sender IDs and traffic, and eSMS Africa handles that registration with each network. Watch for announcements from the ARPTIC on bulk messaging, because the authority's remit now covers both telecoms and personal data.
Consent and the Digital Code
Title III of the Digital Code (Ordinance-Law 23/010, published in the Official Journal on 11 April 2023) sets out the personal data rules. According to DLA Piper's summary, consent can be withdrawn at any time, data subjects can complain to the authority if their data is used without consent, and personal data breaches must be notified to the authority without delay.
We have not found an SMS-specific anti-spam rule from the regulator. That does not make cold marketing safe. A sound policy that fits the Digital Code and the way operators police traffic is:
- Send marketing only to people who opted in, and record where and when.
- Honour every opt-out immediately; the eSMS opt-out list blocks future sends to that number.
- Keep service messages (receipts, OTPs, alerts) on a separate list from promotions.
- Do not share or buy customer lists between companies without explicit consent.
Our older compliance notes for DR Congo list the general rules; this section is the part that changed with the Digital Code.
Four networks, one country
No single network covers the whole country well, and loyalty varies by province. A list from Kinshasa will look different from one collected in Goma or Lubumbashi, and many people carry SIMs on two networks. Sending through one route to all four networks is the only way to avoid silent gaps.
Store every number as +243 followed by 9 digits. Local habits include writing a leading 0 (for example 081..., 099...), which must be removed. Prefixes give a rough idea of the network, but rely on delivery reports, not prefixes, to see what is actually reaching handsets. Our guide to receiving delivery reports shows how to log them per network.
Choosing the language by region
French is the safe default for anything formal: bank alerts, contracts, government and NGO notices. For reminders and community messages, the national language of the area often gets better attention:
| Region | Widely used alongside French | Simple sign-off |
|---|---|---|
| Kinshasa and the west | Lingala | Matondo (thank you) |
| North and South Kivu, Haut-Katanga, the east | Swahili | Asante (thank you) |
| Kongo Central | Kikongo | Keep to French unless a native speaker writes it |
| The Kasai provinces | Tshiluba | Keep to French unless a native speaker writes it |
Lingala and Swahili are usually written with plain Latin letters, so they stay in GSM-7: 160 characters per message. French accents need care: é and è are fine, but ç and circumflex letters such as ê switch the message to Unicode, cutting it to 70 characters per part.
Dollars or francs in your messages?
DR Congo runs a dual-currency economy. Larger amounts such as rent, school fees and loan instalments are often quoted in US dollars, while small purchases and airtime are in Congolese francs. Mirror what is on the customer's invoice and never mix both in one message. Write "USD 45" or "45 000 CDF" in full; the dollar sign is in GSM-7, but a currency code avoids any confusion.
Mobile money is spread across networks: M-Pesa on Vodacom, Airtel Money, Orange Money and Afrimoney on Africell. Name the wallet and the merchant number the customer should use.

Use cases that work in DR Congo
- Humanitarian and NGO programmes: distribution dates, cash transfer notices and health campaigns in the east, in Swahili and French.
- Microfinance and banks: repayment reminders, transaction alerts and OTPs.
- Schools: fee reminders in USD and term notices.
- Mining and logistics: shift changes, site access codes and convoy updates.
- Apps and fintechs: login and payment verification.
OTP across four networks
For login and payment codes, use eSMS Verify. It generates the code, sends it, limits retries and checks it, so you never store codes yourself:
curl -X POST https://sms.esmsafrica.io/v1/verify/start \
-H "Authorization: Bearer esms_live_..." \
-H "Content-Type: application/json" \
-d '{"to": "+243810000001", "app_id": "vera_..."}'
curl -X POST https://sms.esmsafrica.io/v1/verify/check \
-H "Authorization: Bearer esms_live_..." \
-H "Content-Type: application/json" \
-d '{"verification_id": "...", "code": "482913"}'
See the Verify docs and our OTP page for DR Congo.
Sender ID
Use your trading name, up to 11 characters. Networks typically ask for your RCCM registration, an authorisation letter and sample messages, and each of the four networks may review it separately. eSMS Africa files it for you: see the DR Congo sender ID page for steps and fees, and our earlier note on sender ID registration in DR Congo. You can test on the eSMS default sender meanwhile.
Cost
A one-part SMS to DR Congo costs CDF 136.3 ($0.059) at the basic tier; business and enterprise rates are $0.059 and $0.059. You pay as you go from USD 20 by card or crypto, with no monthly fee. Live prices are on the pricing page and coverage on the DR Congo page.
Setup checklist
- Map your audience by province and pick French, Lingala or Swahili per segment.
- Normalise numbers to +243 and 9 digits, removing the leading 0.
- Record opt-in for every marketing contact and keep service lists separate.
- Register your sender ID across all four networks.
- Decide on USD or CDF per message type, matching invoices.
- Name the right mobile money wallet in payment reminders.
- Run a test batch to each network and check delivery reports.
- Assign someone to watch ARPTIC announcements on data protection and messaging.
Frequently asked questions
Which regulator covers SMS in DR Congo?
The ARPTC regulates telecoms while the transition to the new ARPTIC, created under the 2020 telecoms and ICT law, is completed. The ARPTIC has also been given data protection functions under the Digital Code.
Do I need consent to send SMS marketing?
The Digital Code bases personal data use on lawful grounds such as consent, which can be withdrawn at any time. Send marketing only to people who opted in and honour opt-outs at once.
Should I write in Lingala or Swahili?
It depends on the region: Lingala in Kinshasa and the west, Swahili in the east. Use French for formal and financial messages, and have native speakers review templates.
Can I quote prices in US dollars?
Yes, and many invoices in DR Congo are in dollars. Match the currency on the customer's bill and write the code in full.
