9-digit ABA routing numbers with a valid checksum: 3·(d₁+d₄+d₇) + 7·(d₂+d₅+d₈) + (d₃+d₆+d₉) ≡ 0 (mod 10). First two digits identify the Federal Reserve district (01-12 for the 12 Fed banks, 21-32 for historical thrifts). The remaining digits are random — these are format-only and don't map to a real bank.
