Comprehensive and Up-to-Date ABA Routing Number Information

Avoid ACH and Wire payment failures by leveraging routing number data directly from the source.

Non-cash payments in the U.S. are rapidly increasing, with volumes at unprecedented levels. At the same time, customers expect payments to be fast, seamless, and convenient.

Incorrect, incomplete or outdated ABA routing numbers lead to failed payments which can place your customers in a difficult position when they rely on you the most. A failed ACH or Wire transaction not only impacts your profitability; it could mean an employee waiting for a crucial paycheck, someone missing their closing date on a new home, or a critical project being delayed due to lack of funds. With each failed payment costing $12.00 USD on average , inaccurate data puts your company at risk of reputational damage, customer loss, and significant financial setbacks.

The LexisNexis® Bankers Almanac® Routing and Transit Number (RTN) File facilitates efficient banking information searches for setting up, investigating and correcting payments. An essential tool for U.S. payment professionals, it provides up-to-date data on financial institutions and payment routing details for nearly 10,000 U.S. financial entities and more than 100,000 branches and locations.
