View detailsFrom Banco Popular de Puerto Rico to mainland banking
Popular, Inc. is the largest financial institution in Puerto Rico, with a history stretching back to 1893 when Banco Popular de Puerto Rico was founded in San Juan. For over a century it has been the dominant bank on the island — serving individuals, businesses, and government entities in an economy that operates under unique structural conditions as a US territory. Popular Bank, the mainland subsidiary, extends that franchise to Puerto Rican diaspora communities in New York, New Jersey, Florida, and the US Virgin Islands.
The relationship between island and mainland operations is central to Popular's identity. Millions of Puerto Ricans have migrated to the continental United States, and many maintain financial ties to the island — sending remittances, managing family property, or operating businesses that span both jurisdictions. Popular Bank bridges that gap with bilingual banking services and products designed for customers who live between two economic realities.
Routing number
Popular Bank's mainland routing number is 021502011. The 021 prefix ties to the Federal Reserve Bank of New York, reflecting the mainland subsidiary's charter. This applies to Popular Bank deposit accounts held in the continental United States — personal and business checking, savings, and money market accounts at branches in New York, New Jersey, and Florida. Customers of Banco Popular de Puerto Rico use a different routing number for accounts held on the island. For domestic ACH transfers and wire transfers involving mainland Popular Bank accounts, use 021502011. Verify on your checks or through Popular Bank's online banking platform.
Hurricane Maria and banking under catastrophe
In September 2017, Hurricane Maria struck Puerto Rico as a Category 4 storm, destroying the power grid, cutting communications, and making roads impassable. For Banco Popular — which operated more branches on the island than any other bank — the challenge was not just financial but logistical: how do you operate a bank when there is no electricity, no internet, and customers can't reach your branches?
Popular deployed mobile ATMs powered by generators, allowed customers to withdraw funds without identification in the immediate aftermath, and worked with FEMA and local authorities to distribute disaster relief payments. Many branches reopened within days, operating on generator power with paper records when electronic systems were unavailable. For months after the storm, Popular functioned as essential infrastructure — processing insurance claims, SBA disaster loans, and federal aid disbursements that were lifelines for families and businesses across the island.
Banking through a sovereign debt crisis
Even before Maria, Puerto Rico had been in economic crisis for over a decade. The island's government accumulated over $70 billion in public debt, leading to the creation of a federal oversight board under PROMESA in 2016 and the largest municipal bankruptcy proceeding in American history. Popular navigated this period by maintaining conservative credit standards and diversifying revenue through mainland operations and fee-based services. The bank continued lending on the island even as competitors retreated — staying when the economics argued for leaving is what distinguishes Popular from mainland banks that treat Puerto Rico as a market to enter or exit based on quarterly projections.
Resilience for businesses that span borders
Popular knows what it means to keep operating when infrastructure fails, economies contract, and every assumption gets tested. For businesses that need that kind of resilience in their everyday financial operations — whether they span Puerto Rico and the mainland or simply need tools that work without interruption — Slash delivers corporate cards, expense automation, and real-time financial visibility built for companies that can't afford downtime or blind spots in their spending.
