Public, routable address (assignable to a host on the internet).
This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
The digit sequence 31524733 first appears in π at position 956,514 of the decimal expansion (the 956,514ordinal-suffix:th digit after the integer 3).
