What the digits in 283971901 mean
The first four digits, 2839, are the Federal Reserve routing symbol. The prefix 28 places the number in the 8th Federal Reserve District (St. Louis), a range the ABA plan set aside for thrift institutions. That is also the district where the bank is headquartered. Digits five through eight, 7190, identify the institution within its Federal Reserve district. The last digit, 1, is a check digit. Weighting the digits 3, 7 and 1 in turn gives 3 x 20 + 7 x 15 + 5 = 170, a multiple of 10, so 283971901 is a well-formed routing number. A mistyped digit almost always breaks that sum.
