GTBank Customer Care Number: The Definitive, Up‑to‑Date Guide

If you need fast help with your Guaranty Trust Bank (GTBank) account, cards, transfers, or digital banking, the bank’s 24/7 contact center (GTConnect) is the primary phone channel. Below are the official customer care numbers, how to reach an agent quickly from Nigeria or abroad, what it costs to call, and practical tips to get your issue resolved on the first attempt.

The details provided here reflect the numbers and routes GTBank publishes on its official channels. Always cross‑check any phone number against the Contact Us or Help Centre pages on gtbank.com before you dial, especially if you discovered the number on social media or a third‑party site.

Official GTBank Customer Care Numbers (GTConnect)

GTBank’s contact center operates 24 hours a day, 7 days a week. Use these numbers to reach an Interactive Voice Response (IVR) menu and, if needed, a live agent. Calls are charged at your network’s standard rates (these are not toll‑free lines).

• Nigeria (shared-cost line): 0700 4826 66328 (0700 GTCONNECT)
• Lagos landline: 01 448 0000
• Mobile alternatives in Nigeria: 0802 900 2900 and 0803 900 3900
• From outside Nigeria: +234 700 4826 66328 or +234 1 448 0000

When calling the IVR, you can self‑serve for common requests (balance inquiries, card hotlisting, basic card/PIN services) or press the option to speak with an agent. If the IVR mentions expected hold times, stay on the line—queue estimates are usually accurate and updated in real time.

For written escalations or follow‑ups, GTBank also provides service email addresses. If you prefer email, use [email protected] or [email protected] and include your full name, the last 10 digits of your account number (never your full card PAN), a concise description of the issue, and any relevant reference IDs from previous interactions.

Availability, Call Costs, and What to Have Ready

GTConnect runs 24/7, including weekends and public holidays. Peak hours that can lead to longer queues are typically 8:00–11:00 and 16:00–20:00 (West Africa Time). Off‑peak wait times commonly range from 2–5 minutes; peak periods can be 5–15 minutes depending on network conditions and service demand.

Calls to 0700 numbers in Nigeria are billed at your carrier’s standard voice rates. Landline calls to 01 448 0000 are generally billed at local landline rates. International calls to +234 numbers incur international tariffs—if you’re abroad and cost is a concern, consider VoIP or roaming bundles provided by your operator.

To speed up verification, have these ready: your full name as on the account, the phone number registered with the bank, your BVN (if available), and answers to standard security questions. GTBank will never ask for your full card PIN or any One‑Time Password (OTP) over the phone; if someone does, hang up and redial an official number.

Calling From Within Nigeria vs. From Abroad

Inside Nigeria, the most reliable route is 0700 4826 66328 (0700 GTCONNECT) or the Lagos line 01 448 0000. If you experience network congestion on one mobile line, try the alternatives 0802 900 2900 or 0803 900 3900, which are often less congested during national peak periods.

From outside Nigeria, dial +234 700 4826 66328 or +234 1 448 0000. If your phone plan has high international voice rates, you can place lower‑cost calls over Wi‑Fi using your carrier’s Wi‑Fi Calling feature (if enabled for Nigeria), or a reputable VoIP provider capable of terminating calls to Nigerian geographic (+234 1) or non‑geographic (0700) numbers.

If you are traveling and lose your card or suspect account compromise, prioritize immediate card hotlisting via the IVR or your digital channels, and then speak with an agent for additional steps. Record the case reference ID the agent provides and keep it with your travel documents for any follow‑up.

What Issues Can Be Resolved Over the Phone and Typical Timelines

Most routine issues can be handled on a single call: basic account inquiries, debit card hotlisting, digital banking access resets, and transaction status checks. For failed domestic transfers (NIP), reversals often complete within hours and up to 24–48 hours in less common scenarios. If the funds remain outstanding beyond that window, an agent can escalate with a formal ticket.

POS/ATM dispense errors on domestic transactions typically reverse within 24 hours, but can take up to 5 business days if backend reconciliation is required. Disputes on international card transactions follow card‑scheme timelines; investigations commonly range from 30 to 45 days, and complex chargebacks can extend to 60–90 days depending on merchant responses.

For fraud‑related cases, immediate hotlisting and account monitoring begin during the call. Follow‑up documentation may be requested by email. Keep copies of any police reports, SMS alerts, or screenshots of suspicious prompts—they significantly improve resolution speed and outcomes.

Secure Alternatives to Calling (If You Prefer Chat or Email)

If phone lines are busy or you prefer written channels, you can reach GTBank through secure digital routes. These channels are useful for attaching screenshots, getting a written trail of the case, and avoiding international call charges while abroad.

Security Best Practices When Contacting Support

Always dial numbers published on GTBank’s official website and avoid clicking phone numbers embedded in unsolicited emails or social posts. GTBank agents will verify you using standard profile questions, but they will not request your full card PIN, full card number, full OTP, or mobile banking password. If anyone asks for those, terminate the call immediately and redial an official line.

When you receive an SMS one‑time code, never read it aloud over the phone unless you initiated a secure action inside the official GTBank app or web banking and the agent specifically guided you to expect it for that action. For added safety, enable transaction alerts on your registered number and email, and review your statements regularly.

If you need to escalate in person, the bank’s head office is in Victoria Island, Lagos: Plot 635, Akin Adesola Street, Victoria Island, Lagos, Nigeria. For branch‑level issues, use the Contact Us page to find the nearest branch and its operating hours before you visit.
