Nigeria’s Biggest Banks by Branch Network in 2026: Access Bank, FirstBank, and Zenith Bank Lead the Pack

Despite the rapid shift toward mobile apps, USSD codes, and agency banking, Nigeria’s biggest commercial banks have refused to retreat from physical branches, and the latest data shows why this strategy still pays off in a market where millions of customers remain unbanked or underbanked.

Compiled from 2025 annual reports and investor presentations, the latest figures from Nairametrics Research confirms that Access Bank, FirstBank, and Zenith Bank command the largest physical footprints in the country, together running more than 1,400 branches. That scale isn’t just about visibility; it reflects deliberate decisions by Tier-1 lenders to maintain a strong cash-handling presence in a still largely cash-reliant economy while simultaneously investing in digital channels.

Why branch networks still matter in a digital-first banking era

A bank’s branch count is often read as a proxy for its retail reach, its commitment to financial inclusion, and its ability to serve corporate clients who still prefer face-to-face transactions for high-value services. Banks with leaner networks, such as Stanbic IBTC and GTBank, have instead built their brand around efficiency and digital banking, proving that branch count alone doesn’t determine financial strength. GTBank, for instance, ranks sixth in branch numbers but reported total assets of N17.76 trillion in 2025, underscoring how asset size and physical footprint don’t always move in tandem.

How the top 10 banks compare on branches, assets, and deposits

Access Bank and FirstBank set the pace at the top

Access Bank holds the top spot with 554 branches nationwide and over 700 across Africa, a footprint built through years of aggressive mergers and acquisitions. Its total assets jumped 24.54% to N51.56 trillion in 2025, while customer deposits surged 53.44% to N34.56 trillion, the steepest deposit growth among the top 10. FirstBank trails closely with 550 branches and more than 820 across Africa, leaning on its legacy as one of Nigeria’s oldest financial institutions to maintain deep retail penetration, even as its asset growth was more modest at 2.74%.

Zenith Bank and UBA anchor the pan-African expansion story

Zenith Bank’s 406 branches support a franchise built around corporate, commercial, and retail banking, with assets climbing to N31.46 trillion. UBA’s 327 branches form part of a wider network of over 1,000 touchpoints across Africa, and the bank has pushed its international ambitions further by opening a branch in the Dubai International Financial Centre, positioning itself as a bridge between African and Gulf markets.

Ecobank’s smaller branch count masks the region’s largest balance sheet

Ecobank’s 273 Nigerian branches might place it fifth on this list, but its total assets of N49.66 trillion are the second-highest among all banks reviewed, just behind Access Bank. This reflects Ecobank’s identity as a pan-African banking group whose strength lies in its regional network across more than 30 countries rather than sheer branch density in any single market.

What the smaller networks reveal about strategy, not weakness

Banks like Stanbic IBTC, Wema, and Sterling operate the leanest networks on this list, yet each posted strong growth. Wema Bank’s assets rose 41.16% even with just 155 branches, powered largely by its digital-first ALAT platform. Stanbic IBTC’s 129 branches support a model built around corporate banking, wealth management, and pension services rather than mass retail footfall. These banks illustrate that a smaller branch count often signals a deliberate digital or niche strategy rather than a shortfall in capacity.

Expert View

Banking analysts note that branch expansion in Nigeria increasingly correlates with deposit mobilization strategy rather than simple market dominance. Industry commentary suggests that banks pairing branch density with digital adoption, as seen with Access Bank and Zenith Bank, tend to record the sharpest deposit growth, since physical branches still drive trust-based account opening in rural and semi-urban areas even when daily transactions move online afterward.
