Free FDIC Bank Lookup

1. 11

   Enter the bank

   Type the bank's name, or its FDIC certificate number if you have it. An entry that is only digits is read as a certificate number.

2. 22

   We read the FDIC record

   The entry is looked up in the FDIC's directory of insured banks and savings institutions, open and closed.

3. 33

   Read the answer

   You see whether the bank is active, where it is, who regulates it, what kind of charter it has and how large it is.

Bulk bank checks run the same lookup on a whole list with one CSV file.

The free tool checks one bank at a time. With a 1Lookup account you upload a CSV file in the dashboard, pick the column that holds the bank names or certificate numbers and download the same file back with the result columns filled in on every row. These rows are invented.

• 2 credits for each bank that is found, a closed bank included, and nothing for a bank that is not found.
• Up to 2 million rows in one CSV file.
• Up to 200 API requests per 10 seconds for each API key, and each account can make up to 1,000 requests a minute in total across all its keys.

The Bank Lookup API returns the same record as JSON from one request.

Send the bank name, with a two-letter state if you like, or the FDIC certificate number to the endpoint with your API key. A bank that is found costs 2 credits, and one that is not found or is mistyped costs 0. Whether it was found is in classification.found, and the other banks a name matched are in insights.bank_lookup_result.other_matches.

To check every bank on a list from your own software, see our Bank Lookup API.

• A bank that has closed is still answered, with its status.

  A closed or merged bank comes back as no longer active with the date it ended, so you can see what a name once belonged to.

• The charter type comes back in plain words.

  You see State commercial bank (not a Federal Reserve member), not a one or two letter code you would have to look up in an FDIC table.

• The total assets show how big the bank is.

  The figure is in whole dollars and carries the date of the quarterly report it came from, so you know how old it is.

• A name that matches several banks says so.

  The best match is shown in full and the page says how many other banks matched, so a common name is not mistaken for one bank.
