Form 2848 has four fax numbers, and the last two differ by where you are standing
Two are chosen by the state in your address. The other two both serve international and territory addresses, and which one applies depends on whether the fax is being sent from inside the United States or outside it — the one distinction on this chart that is easy to read past. All four are below, read off the IRS instructions that publish them.

Power of Attorney and Declaration of Representative. Authorize someone to represent you before the IRS.

The IRS says these numbers change, and says it on the chart itself
The instructions carry their own warning on this chart: these numbers may change without notice, with updates posted under Recent Developments at IRS.gov/Form2848.

That warning is the reason every number on this page sits above the URL it was read from and the date it was read. The oldest reading here is from September 13, 2026. A check in our build fails the site when any reading on this page passes six months, so a number cannot quietly age here. What it cannot do is notice a change made this morning — which is why you get a source link and a date rather than a badge claiming the page is verified.
Form 8821 uses the same four numbers
The two forms travel together and the authorization they grant is not the same, but the destination is.
Form 8821 shares the 2848 fax numbers and its state groupings. It carries the same warning that the numbers may change without notice.

Tax Information Authorization is the narrower of the two — let someone inspect or receive your tax information — and which form a situation calls for is a question for the instructions and for whoever is being authorized. If you are sending both, they are separate submissions to the same number rather than one fax with both forms in it.
Check the number on your own paperwork first
If the IRS has written to you about the matter this authorization covers, the fax number on that notice wins. Correspondence routes to the unit handling your case, and that unit’s number is not always the one on the published chart. The rest of the IRS record is held to the same rule, and says the same thing about every number in it.
What a transmission record does and does not settle
A confirmation says the receiving fax system answered and acknowledged the pages. It does not say the authorization was recorded, that it was accepted, or that anyone has looked at it — those are the IRS’s to report on its own timetable, and no fax service can tell you otherwise. What a fax confirmation actually proves is worth two minutes before relying on one against a deadline.
Sending it
Upload the pages, check the preview, and send. No account, nothing to cancel, and the card is authorized when you press send and charged only once the receiving fax system acknowledges the pages. If it never does, you are not charged. A cover sheet is generated with the routing fields filled in from what you entered.
