What is a CAF Number and How To Get One: Step-By-Step Guide

If you are looking to start offering tax resolution services, there’s a few things you’ll need to take care of first. One of those things is getting a CAF Number. We’ll walk you through that process here.  

What is a CAF Number? 

A Centralized Authorization File Number, or CAF Number, is a nine-digit number issued by the IRS the first time a tax preparer files tax information authorization or power of attorney. The IRS uses this unique number to keep track of requests for client information, like transcripts. 

How to get a CAF Number

To get a CAF Number, you can submit Form 2848 or 8821 to the IRS and put “none” in the space asking for a CAF number. Within a few weeks, you will receive an assigned CAF Number from the IRS. 

Once you have your CAF Number, you should use it on all future forms. 

What is Form 2848? 

This form allows you  to request power of attorney for your clients. Learn more about how to fill out this form (and get it approved the first time) here. 

What is Form 8821? 

Filing IRS Form 8821 authorizes tax professionals (or other individuals or organizations) to get confidential tax documents for their client. It can also cancel prior tax information authorizations that are no longer needed. Learn more about filling this form out here. 

What if I forgot my CAF Number?

If you can’t find your CAF Number, don’t worry. You simply need to call the Practitioner Priority Services at 866-860-4259. After verifying your identity, they will tell you your CAF Number.
