Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,000,025 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
