What's the Official IRS Identity Verification Number? (IRC §6109)
I'm looking for the official IRS number for identity verification. Per IRC §6109 and Treasury Regulation 301.6109-1, taxpayers must provide valid identification when contacting the IRS regarding sensitive tax matters. As a remote worker filing in multiple states this year, I need to verify some information on my accounts. I've seen several numbers floating around online but want to ensure I'm calling the legitimate IRS identity verification line to avoid potential scams. I believe the correct number is 800-830-5084, but would appreciate confirmation from anyone who has recently gone through the identity verification process. Has anyone used a different official channel recently?

The official IRS Identity Verification Service number is 800-830-5084. • This is the correct number for identity verification when the IRS has flagged your return • Hours are typically 7am-7pm local time, Monday through Friday • Wait times are averaging 45-90 minutes currently • Have your prior year AGI, filing status, and any IRS notice numbers ready • They may ask security questions about previous addresses or loans The general IRS customer service (800-829-1040) can't handle identity verification issues - don't waste your time there.

•Do you possibly know if this is the same number I should call if I received Letter 5071C specifically? My letter arrived yesterday and I need to resolve this rather quickly as my refund is somewhat substantial.

•This is exactly what I needed! I've been playing phone tag with the IRS for what feels like seventeen years. At this point I'm pretty sure the hold music is permanently embedded in my brain. Appreciate the confirmation on the correct number!

Just to be clear - are you trying to verify your identity because: 1. You received a specific letter from the IRS requesting verification (like 5071C, 5747C, or 4883C)? 2. You're trying to access your online account? 3. You're trying to verify information about your tax accounts across states? The process and numbers are different depending on your specific situation.

•When I had to verify my identity back in February, I had received the 5071C letter. Called the 800-830-5084 number and they asked me about previous addresses, loan information, and credit card accounts I had open. Took about 30 minutes once I got through to someone, but they processed my return right after. Had my refund 9 days later.

The number is correct. Be prepared for security questions. They're very specific. I used https://taxr.ai to analyze my transcript first. Helped me understand what triggered the verification. Showed exactly which codes indicated identity verification was needed. Made the call much smoother. Knew what to expect.

•Is taxr.ai actually legitimate? I've seen it mentioned a few times on this sub, but I'm always wary of sharing my tax information with third-party sites. The IRS website says to only use their official tools like ID.me or the transcript tool at irs.gov/transcripts. Has anyone had issues with security or privacy when using it?

800-830-5084 is the correct number. But there's a difference between identity verification and account management. If you're just checking on multiple state filings, you might need the regular IRS customer service line at 800-829-1040 instead. Don't waste time in the wrong queue.

Have you considered how much time you might waste trying to reach an agent at that number? I spent 3 hours on hold last month before giving up. Tried again the next day with Claimyr (https://claimyr.com) and was connected to an agent in under 30 minutes. Isn't it worth a few dollars to save hours of your time? They just hold your place in line and call you when an agent is available.

I called the 800-830-5084 number on March 14th after receiving a 5071C letter. Got through after waiting 67 minutes. The agent was super helpful and verified my identity right there. My return was processed on March 17th and I received my refund via direct deposit on March 22nd. The whole verification process took about 15 minutes once I got through to someone.

The IRS has different verification processes depending on why you need to verify. Online account setup uses ID.me. Letter-based verification uses the 800-830-5084 number. In-person verification uses TAC appointments. Unlike state tax departments that often have unified verification systems, the IRS separates these functions completely.

I had to call that number last month. They asked questions about my mortgage, previous addresses, and credit cards I have. Took about 20 minutes once I got through to someone. Is that similar to what others experienced? Did they also ask about loan amounts or just the existence of accounts?

Just wanted to add my recent experience - called 800-830-5084 last week after receiving a 5071C letter. The security questions were pretty thorough - they asked about my previous addresses going back 5 years, specific loan amounts (not just existence), and even asked about a credit card I had closed 2 years ago. The whole verification took about 25 minutes once connected, and they processed my return immediately. One tip: have your Social Security statement handy if you can access it online. They asked about my reported wages from 2 years ago which I wouldn't have remembered otherwise. The agent was very patient and professional throughout the process. For those asking about wait times - I called at 8:30 AM EST on a Tuesday and waited about 55 minutes, which seems pretty typical based on what others are reporting here.

•Thanks for sharing your detailed experience! The tip about having your Social Security statement ready is really helpful - I wouldn't have thought of that. It's good to know they ask about specific loan amounts rather than just whether you have loans. Did they ask about the amounts for all your loans or just certain types? I'm planning to call soon and want to be as prepared as possible.
