United Community Bank NACHA file requirements

United Community Bank accepts NACHA-format ACH files through United's business online banking. The bank calls the feature "ACH file upload / Direct Send transmission". Here is what its published documentation requires.

Independent documentation. Not affiliated with or endorsed by United Community Bank.

Before you upload, run the file through the free ACH file validator. It checks the structural rules and United Community Bank's documented quirks in your browser; the file never leaves your computer.

How United Community Bank ACH file upload works

What to confirm with your United Community Bank treasury contact

Four values are assigned per customer and only the bank can tell you them: your Company ID (often not just your EIN), the exact immediate origin value they expect in the file header, whether your agreement is set up for balanced or unbalanced files, and your cutoff times and settlement option. Get them in writing before the first upload.

Building the file

Most accounting software, including QuickBooks and Sage 50, cannot export a NACHA file directly. If your system exports one and United Community Bank still rejects it, the validator will usually name the exact line and field. If the reason will not yield, the format setup service works it out with you. This software formats and checks files only. It moves no money; funds move solely through your own bank under your agreement with them.
