CAF Number & SOR Activation Guide for Tax Professionals

If your CAF number is not properly activated, you cannot pull client transcripts.

If your SOR mailbox has never been set up, nothing gets delivered.

Most preparers don't find out until a client is sitting across from them and nothing is working.

That's the problem this guide solves.

Who This Is For

This guide was built for:

• New tax preparers in their first 1 to 2 seasons who have hit a wall with IRS e-Services
• EROs and office staff who need practitioner access set up correctly from day one
• Tax professionals who have a CAF number but never activated their SOR mailbox
• Anyone who has been told to "just call the IRS" and knows there has to be a better way

If you submitted Form 2848 and still cannot pull transcripts, or your SOR mailbox is empty and you do not know why, this is where you start.

What You Will Be Able to Do

After completing this guide, you will:

• Have your CAF number correctly requested, activated, and linked to your Tax Pro Account
• Have your SOR (Secure Object Repository) mailbox live and receiving IRS transcripts
• Know exactly which transcript types get delivered and how to access them
• Understand the 60-day login rule and never lose SOR access again
• Know which IRS department to call when something goes wrong and stop wasting hours on the wrong line

This guide connects your CAF number, SOR mailbox, and Transcript Delivery System in one place. Built from real IRS e-Services experience. Not textbook compliance content. Not a Google summary. Practitioner-to-practitioner knowledge from people who have already done the hard part.

No shortcuts. No surprises later.

Frequently Asked Questions

1. Do I need a CAF number if I already have a PTIN? Yes. They are completely separate.

Your PTIN is your preparer ID for filing returns. Your CAF number is the credential that authorizes you to access client transcripts and represent taxpayers before the IRS. You need both. They serve different functions.

2. Why isn't my SOR mailbox receiving any transcripts? There are a few common reasons. Your SOR may not be activated. Your CAF may not be properly linked. Or transcripts may need to be requested through PPS first. This guide walks through each scenario so you know exactly what to check.

3. What happens if I don't log into my SOR for 60 days? Your SOR gets purged. Transcripts are deleted. Access is lost.

This guide explains the rule clearly and tells you exactly how to keep your mailbox active so it never happens.

4. My CAF number is in pending review. What do I do? This happens more often than people realize, sometimes even as a false positive. The guide explains why it happens, what it means for your access, and who to contact to get it resolved.

5. Can my office staff use my CAF number, or do they need their own? Delegated users need to be listed on authorizations under their own CAF numbers. This guide covers how multi-user tax offices should structure access to avoid authorization failures.

6. Is this for a solo preparer or a full tax office with staff? Both. Whether you are a solo ERO or building out a team, the guide covers what every user needs to be properly authorized.
