MTN Customer Care Numbers and How to Reach the Right Support Fast

MTN operates in 19 countries across Africa and the Middle East and serves over 290 million subscribers (MTN Group, FY2023). Because customer care short codes vary by country, using the correct number saves time and ensures your query reaches the right team. Below you’ll find verified contact numbers in MTN’s largest markets, practical calling tips, charges information, and alternative channels that get results quickly.

This guide focuses on the primary, toll-free short codes MTN advertises for consumer support in each market, alongside official websites and key addresses that can help if you need in-person assistance or escalations. Unless noted, the lines below operate 24/7 for standard consumer issues such as SIM registration, airtime/data queries, device/network problems, and mobile money assistance.

Quick Reference: MTN Customer Care Numbers by Country

• South Africa: Dial 135 (free from an MTN line); from other networks call 083 135 (standard rates). Website: https://www.mtn.co.za
• Nigeria: Dial 300 (free from an MTN line; unified short code introduced by the NCC in May 2023). For industry complaints to the regulator after 24–48 hours with your operator, dial 622. Website: https://www.mtn.ng
• Ghana: Dial 100 (free from an MTN line). Website: https://www.mtn.com.gh
• Uganda: Dial 100 (free from an MTN line). Website: https://www.mtn.co.ug

Tip: If you’re roaming, your MTN short code may still connect, but roaming voice rates apply. If the short code doesn’t work while abroad, use your country’s MTN website chat/contact form or the MyMTN app over Wi‑Fi for free support.

MTN South Africa — 135 (Primary Care Line)

From an MTN South Africa number, dial 135 for free, any time. From other local networks, dial 083 135 (standard network rates apply). For international callers, use +27 83 135. The 135 line supports prepaid, postpaid, and fibre queries. Average resolution times vary by issue, but simple account inquiries are often resolved during the first call; complex network or billing disputes may require 24–72 hours for investigation.

Self-service options on 135 let you check balances, manage add‑ons, upgrade, or log a network fault without waiting for an agent. For quick balance and bundle management without calling, dial *136# (USSD) or use the MTN app. If your SIM is lost/stolen, call 135 immediately to suspend service and protect your number and mobile money wallet.

Addresses and Online Support (South Africa)

Corporate head office: MTN Group, 216 14th Avenue, Fairland, Johannesburg, 2195, South Africa. For retail device/service support, use the Store Locator on https://www.mtn.co.za to find the nearest MTN store and its trading hours. Bringing a physical ID document (RSA ID, passport, or driver’s license) expedites SIM swaps or account changes.

MTN South Africa’s online help is available via the “Support” section on the website and in the MTN app. For billing disputes over R200 or complex technical cases, submit a written query via the online form to obtain a reference number; this helps if you need to escalate further.

MTN Nigeria — 300 (Unified Customer Care)

Dial 300 from your MTN Nigeria line for toll‑free customer care. This unified care short code was implemented nationwide in May 2023 by the Nigerian Communications Commission (NCC) as part of the harmonized short code initiative. The legacy 180 number is no longer the primary care line. If your issue remains unresolved after contacting MTN, escalate to the NCC consumer line 622 (8:00–8:00 daily per NCC guidelines).

Typical use cases on 300 include SIM/NIN linkage assistance, bundle queries, network issues, and account security. For quick self‑service, Nigeria also uses harmonized USSD codes: recharge with *311*VoucherPIN#, data with *312#, borrow with *303#, and NIN services with *996# or *323# (check prompts). MTN’s site (https://www.mtn.ng) and the MyMTN NG app provide live chat and ticket logging to avoid voice queue times.

Addresses and Practical Notes (Nigeria)

Head office (customer-facing landmark): MTN Plaza, Falomo Roundabout, Awolowo Road, Ikoyi, Lagos, Nigeria. Walk‑in centers nationwide handle SIM replacements, device checks, and KYC updates; carry a valid government ID and your NIN for any SIM‑related service.

Charges: Calls to 300 are free from MTN lines. Calls from other networks use their standard rates. When roaming, use the app or website chat to avoid voice roaming charges. Keep your complaint reference number from MTN handy if you need to escalate to 622.

MTN Ghana — 100 (Contact Centre)

Dial 100 from your MTN Ghana line for toll‑free support. The IVR offers language options and quick paths to mobile money (MoMo) support, bundle management, and technical assistance. The line operates 24/7. For online help and store locations, visit https://www.mtn.com.gh.

For MoMo issues such as wrong transfers or suspected fraud, contact support immediately via 100 and choose the MoMo option; rapid reporting within minutes significantly improves recovery chances if funds are still in transit. Use the official MoMo short code *170# for wallet actions; do not share your OTP or PIN with anyone, including callers claiming to be from MTN.

Addresses and Identification (Ghana)

MTN Ghana (Scancom PLC) headquarters: MTN House, Independence Avenue, West Ridge, Accra, Ghana. Walk‑in service centers across Accra, Kumasi, Takoradi, Tamale, and regional capitals handle SIM registration updates and device support—check locations and hours on the website’s Store Locator.

Bring your Ghana Card for SIM registration or SIM swap requests. If your SIM is lost, ask to blacklist the old SIM immediately and complete a SIM swap with your ID to secure your number and MoMo wallet.

MTN Uganda — 100 (Customer Care)

Dial 100 from an MTN Uganda line for customer care at no charge. This line supports airtime/data bundles, MoMo wallet queries, device/network troubleshooting, and SIM registration. For self‑service, use the MyMTN app or the USSD menu displayed on your SIM Toolkit or by dialing the on‑screen prompts in the app.

Online assistance is available via https://www.mtn.co.ug, including live chat, store locator, and social care channels. If you are reporting a MoMo issue, contact support promptly and have your recent transaction details ready to speed up remediation.

Addresses and Walk‑in Support (Uganda)

MTN Uganda headquarters: MTN Towers, 22 Hannington Road, Kampala, Uganda. Major service centers in Kampala and regional towns handle SIM swaps, KYC updates, and device diagnostics. Store hours vary by location; confirm on the website before visiting.

Charges: Calls to 100 are free from MTN lines. Standard network rates apply if you call from another operator. Roaming charges apply when abroad—prefer app or web chat over Wi‑Fi to avoid costs.

What to Prepare Before You Call MTN Customer Care

• Account details: Your MTN number, recent recharge or transaction references, and, where applicable, your national ID (e.g., RSA ID, NIN in Nigeria, Ghana Card, Ugandan NIN).
• Device/SIM info: Phone model, IMEI (dial *#06#), and SIM serial (ICCID) from the SIM card pack for SIM swap or network issues.
• Evidence: Screenshots of error messages, exact time/date of failed calls or transactions, and any bank or wallet reference numbers for billing/MoMo queries.
• Security: Never disclose your wallet PIN, full card details, or one‑time passwords (OTPs). MTN agents will not ask for your PIN/OTP.

If your issue is urgent (lost phone/SIM, suspicious MoMo activity), call immediately and request a temporary block on services. Then follow ID verification steps for restoration. Keep your case reference number; it is essential for follow‑ups or regulatory escalation (e.g., NCC 622 in Nigeria) if required.

Service Hours, Charges, and Alternatives

MTN’s core customer care lines listed above operate 24/7 in the countries covered here. Calls are free from MTN lines to the official short codes (135 in South Africa; 300 in Nigeria; 100 in Ghana and Uganda). From other networks, normal call charges apply. When roaming internationally, voice calls to care lines are billed at roaming rates—use the MyMTN app or your country site’s live chat over Wi‑Fi to avoid charges.

For non‑urgent tasks like bundle changes, balance checks, and basic troubleshooting, self‑service via USSD or the MyMTN app is often faster and available even during network congestion. For complex billing or technical investigations, submit a written ticket via your country website to obtain a reference and timestamp, which simplifies follow‑ups and escalations.
