Democratic Republic of the Congo Country Code +243
Important: there are two neighbouring countries named “Congo”. This page is for the Democratic Republic of the Congo (DRC, Congo-Kinshasa), whose country code is +243. The Republic of the Congo (Congo-Brazzaville) uses +242 and has a separate country page.
The international country calling code for the Democratic Republic of the Congo (DRC) is +243. You will see this on numbers used by ministries in Kinshasa, mining and logistics operations in the copperbelt, humanitarian agencies and NGOs, churches, schools, trading companies and local users throughout this very large Central African country.
DR Congo uses a national system with a trunk prefix “0” for calls inside the country. Domestic numbers are typically written as 0XX XXX XXXX (10 digits including the leading zero). When you dial from abroad with +243, you drop that leading 0. The same subscriber number is used, but without the trunk prefix.
This guide explains how Congolese phone numbers are structured, how to dial +243 from Europe, the Americas and neighbouring African countries, how the Africa/Kinshasa and Africa/Lubumbashi time zones work, and what to keep in mind when calling remote project sites, field teams and local mobiles in the DRC.
Example mobile (Kinshasa)
+243 81 234 5678
Domestic format: 081 234 5678 (leading 0 is removed when adding +243).
Example mobile (mining region)
+243 99 234 5678
Common for mobiles with operator prefixes in the 9x range (illustrative).
Time & region
UTC+1 & UTC+2
West (Kinshasa): UTC+1 · East (Lubumbashi, Goma): UTC+2.
Overview – where +243 is used
The code +243 belongs to the Democratic Republic of the Congo, a vast country stretching from the Atlantic coast deep into Central Africa. You will see +243 numbers attached to ministries and provincial authorities, mines and logistics bases, health facilities, schools, churches, local businesses and the personal mobiles of residents and humanitarian staff.
In practice, a very large share of real-world communication uses mobile numbers, because fixed-line infrastructure is limited outside major cities. Voice calls, SMS and messaging apps are all tied to these +243 mobiles, so storing them in a consistent international format makes your address books, CRMs and security protocols far more reliable.
You may see numbers written as 081 234 5678, 099 234 5678, +243 81 234 5678 or 00243 81 234 5678. All of these can usually be normalised to the same thing internally: +243812345678, and then displayed in whichever grouping your product uses.
Because there is also a Republic of the Congo next-door with country code +242, it is good practice to store an explicit country field or ISO code alongside the number (for example CD / COD) to avoid mixing contacts from the two countries when you run reports or messaging campaigns.
Typical +243 use cases in the field
- NGOs & humanitarian operations – field bases, medical teams, logistics hubs and security hotlines.
- Mining & natural resources – mine sites, contractors, transport companies and service providers in the copper and cobalt belts.
- Government & business – ministries, provincial offices, banks, trading companies and schools, especially around Kinshasa and other major cities.
Many contacts operate in areas with limited coverage or frequent power cuts. When a +243 number is critical for safety or operations, consider saving at least two independent contact paths (for example, a mobile, a satellite device and an email address).
Phone number formats in the DRC (+243)
Pattern: domestic 0XX XXX XXXX → intl. +243 XX XXX XXXXThe Congolese numbering system uses a national trunk prefix “0” for domestic calls. People in the DRC usually write and dial numbers as 0XX XXX XXXX. For international calls, the leading 0 is removed and replaced with +243.
- • Country code: +243.
- • Domestic (national) format: usually 0XX XXX XXXX, where 0 is the trunk prefix and XX identifies an operator or region.
- • International format: +243 XX XXX XXXX – the same digits as national format but without the initial 0.
- • Mobile numbers: commonly use prefixes in the 8x or 9x ranges (for example, 081, 082, 099) before the subscriber block.
- • Fixed lines: exist mainly in larger cities; they also use a leading 0 nationally and drop it when written with +243.
- • Length: domestically you see 10 digits including the trunk 0. The subscriber number component (without the 0) has 9 digits.
Exact prefixes are assigned by the Congolese regulator and mobile operators and may evolve over time. When building validation logic, avoid hard-coding too many assumptions; instead, focus on the “drop 0 and add +243” rule and allow 9 significant digits after the country code.

How to dial Democratic Republic of the Congo (+243)
1. From the USA or Canada
To call a Congolese number from the US or Canada:
- Dial 011 – international access code.
- Dial 243 – country code for DR Congo.
- Dial the national number without the leading 0.
Example (US → Kinshasa mobile 081 234 5678): 011 243 81 234 5678.
2. From Europe or many other countries
In many countries the international prefix is 00:
- Dial 00 – international prefix.
- Dial 243 – DR Congo country code.
- Dial the national number without the trunk 0.
Example (France → mobile 099 234 5678): 00 243 99 234 5678.
3. Dialing inside DR Congo & calling abroad
- Within DR Congo: dial the full national format with the trunk 0 – for example 081 234 5678 or 099 234 5678.
- From DR Congo to other countries: dial 00 + destination country code + national number (for example 00 32 2… for Belgium, 00 1… for the US).
- Short codes: mobile operators and local authorities use short numbers for balance checks, customer care or city services; these work only from within the national network.
When you capture numbers in the field, encourage teams to write both a “local” form (with 0) and a “global” form (with +243). This makes your contact lists much easier to consolidate later.
Normalisation tip: if someone writes 00243 812345678,
+243 81 234 5678 or 0812345678, all of these represent the same underlying
number. Strip spaces, remove any leading 00 or +, drop a single leading
0 if present, then prepend +243 in your database.
Time zones in DR Congo – Africa/Kinshasa & Africa/Lubumbashi
The Democratic Republic of the Congo spans two time zones:
- • Western DRC (including the capital Kinshasa) uses UTC+1. The IANA time zone name is Africa/Kinshasa.
- • Eastern DRC (including cities such as Lubumbashi, Goma and others) uses UTC+2, IANA Africa/Lubumbashi.
When you schedule calls, it is crucial to know which part of the country your contact is in. A field officer based in Kinshasa and a site supervisor in Lubumbashi will typically be one hour apart even though they share the same country code +243.
DR Congo does not generally follow the European pattern of daylight saving time shifts, but some systems and maps may still display historical DST data. For reliable software, always attach the correct IANA zone (Africa/Kinshasa or Africa/Lubumbashi) to each user or site.
Time difference examples
| Location | Time zone | Offset vs Kinshasa | Offset vs Lubumbashi |
|---|---|---|---|
| Kinshasa | Africa/Kinshasa (UTC+1) | Reference | +1 hour |
| Lubumbashi | Africa/Lubumbashi (UTC+2) | −1 hour | Reference |
| London | Europe/London | ≈ −1 hour (typically) | ≈ −2 hours (typically) |
| Johannesburg | Africa/Johannesburg (UTC+2) | ≈ +1 hour | ≈ same time |
| New York | America/New_York | ≈ −6 to −7 hours | ≈ −7 to −8 hours |
| Beijing | Asia/Shanghai (UTC+8) | ≈ +7 hours | ≈ +6 hours |
For critical operations (for example, medical support lines or safety check-ins), consider displaying both the local time at the caller and the local time at the site in your dashboards so teams can quickly see who is on or off shift.
Safety & emergency calls in the DRC
Unlike some regions where a single short code (such as 112 or 911) is universally standardised, emergency calling arrangements in the Democratic Republic of the Congo can be more fragmented. Large cities may have official police, fire or medical numbers, but coverage and reliability vary, and there is no guarantee that one specific number will work nationwide on every network.
For that reason, organisations working in the DRC – particularly NGOs, embassies, mining operations and companies with travelling staff – usually put a strong emphasis on their own internal emergency procedures. These often include dedicated +243 mobile numbers, satellite phones or regional security lines instead of relying solely on local public hotlines.
Local emergency numbers
Vary by city
Cities and provinces may publish their own numbers for police, fire or ambulance. Ask your hotel, employer or local partner which numbers are currently active in your area.
Mobile networks
Operator-specific
Some mobile operators provide short codes for customer care or assistance. These are not always general emergency numbers and work only from their own network.
Organisation protocols
Critical in practice
Many organisations share internal emergency contact cards listing site security, medical focal points, transport coordinators and duty officers, all with +243 numbers and backups (for example satellite lines).
Traveller advice
Save key contacts
Before travelling, save local +243 numbers for your organisation, hotel, local partners and any security lines. Check that they are stored in +243 format so they still work if your SIM or roaming setup changes.
Because conditions on the ground can change quickly, always rely on up-to-date local guidance (for example from your employer, embassy or NGO) about which emergency numbers or protocols to use in the specific area where you are operating.

DR Congo country code +243 – FAQ
What is the country code for the Democratic Republic of the Congo?
The international country calling code for the Democratic Republic of the Congo is +243. When dialling from abroad, you typically call your international access code (00 or 011), then 243, then the national number without the leading 0.
Is +243 the same as +242?
No. +243 is for the Democratic Republic of the Congo (DRC, Congo-Kinshasa). +242 is for the neighbouring Republic of the Congo (Congo-Brazzaville). They are different countries with different capitals, regulators and numbering plans.
Why do Congolese numbers sometimes start with 0?
The 0 at the beginning of a Congolese number is a national trunk prefix. It is used when you dial inside the DRC. When you add the international prefix and country code (for example +243) you drop this initial 0 and keep the rest of the digits.
How should I store +243 numbers in my systems?
The most robust choice is the E.164 format: always store DR Congo numbers as +243 followed by the national digits without the leading 0, with no spaces or punctuation. For example +243812345678. Spacing like +243 81 234 5678 can be applied on the fly in your user interface.
What time zone is the DRC in?
The Democratic Republic of the Congo has two time zones. Western areas including Kinshasa are on UTC+1 (Africa/Kinshasa), while eastern regions such as Lubumbashi are on UTC+2 (Africa/Lubumbashi). When you plan calls, always confirm which part of the country your contact is in.
Are emergency numbers standardised across the whole country?
Public emergency numbers and short codes can differ between cities and networks, and coverage may not be consistent nationwide. Many organisations therefore rely on their own internal emergency lines and security protocols in addition to any local public numbers. Always follow the guidance of your employer, embassy or NGO for the specific region where you are based.
