Get bank name from routing number [closed]

Question

Googling for an array of common routing numbers and their US-based bank names pulls up a whole list of spammy sites. Can anyone point me to where I could find such an array or better yet a javascript/jquery plugin that handles the routing number parsing?

I know Stripe must at least have this list because they tell me my bank name when I give them my routing number during their OAuth protocol.

If it is not possible for me to get this list, I guess Stripe must have special clearance(?) which seems strange to me since these numbers are the same for everyone who uses each bank.

Regardless, what's the deal with the scarcity of information here?

You might be looking for something like this (not free): lyonslive.com/Routing-Number-Verification/…. Update: one site that had some legal trouble when they republished the information listed their source as: fededirectory.frb.org/download.cfm - hope this is of some use! – Osmo

I assume you mean US banks, so have have made a small clarification. I'm in the UK and have never heard of 'routing numbers' - I think it's the equivalent of our sort code. – Wasp

The list is available here: https://www.fededirectory.frb.org/FedACHdir.txt (replacement link)

Even better, routingnumbers.info has an API that allows to access it like this:

https://www.routingnumbers.info/api/data.json?rn=xxxxxxxxxx

It returns a JSON object where customer_name is the name of the bank.

That site looks like it might or might not be legit. Couldn't figure out who runs it, and rate limits, etc. – Pizzicato

www.routingnumbers.info looks great but they now display a message warning their data may be out of date. – Shin
