Understanding Grant Codes, Numbers, and Compliance

A Plain-Language Guide for Nonprofit Leaders

Grants often come with numbers, letters, and codes that can feel confusing or intimidating. These identifiers aren’t just paperwork—they define how funding can be used, tracked, and reported. Understanding them helps nonprofits stay compliant, avoid costly mistakes, and build long-term funder trust.

At ACL Consulting, we help nonprofits translate these requirements into clear, manageable systems.

Why Grant Codes Matter

Every grant comes with rules. Grant identifiers help answer key questions such as:

  • What can this money be used for?
  • How long can we spend it?
  • What reporting is required?
  • What happens if we use it incorrectly?

Using the right codes ensures:

  • Funds are spent properly
  • Reports match funder expectations
  • Audits go smoothly
  • Future funding remains possible

The Most Common Grant Codes Explained

Why it matters:
The ALN determines:

“This number tells us what the grant money is allowed to pay for.”

What it is:
A unique identifier for your specific federal grant award.
