# Inside the call report data

Lesson 1 of [Research credit union records in depth](https://creditunions.fyi/academy/research-credit-union-records.md), 16 minutes.

Each listing comes from the NCUA quarterly call report data, also called the 5300 quarterly data. You can download the same files from the NCUA and check a listing yourself.

## The files this site reads

- **FOICU**: charter number, name, address, charter type, field-of-membership code, low-income flag and year organized.
- **FS220**: total assets and member count.
- **FS220D**: the reported website.
- **The branch table**: branch locations and the main-office phone.

The current listings come from the 2026-06 cycle file, read on 2026-10-20. The site matches each row to its listing by the NCUA charter number.

## Public domain

The NCUA data is a work of the US Government. It is in the public domain (17 U.S.C. 105), so you can read and share it freely.

## The field-of-membership code

Federal credit unions report a type-of-membership code. The listing shows the NCUA wording for that code, such as Military, Educational, Community or Associational - faith-based. State charters report no code, so their field stays empty.

## What the data cannot tell you

The call report holds balance-sheet and register figures. It has no rates, no fee schedule and no reviews of service. Do not try to read those details from it.
