No. The US Postal Service does not accept faxed change-of-address forms. You can file a change of address online through the USPS website or in person at a post office, and those are the only two routes the Postal Service offers.
LetterAgent cannot fax a change of address to USPS either, because there is no fax destination to send it to. This is one of those cases where the honest answer is a plain no, and the useful part of the article is what to do instead. A faxed form that nobody accepts is not a filed change of address, and mail will keep going to the old address while you wait for a confirmation that never comes.
A change of address is an identity-sensitive request: it redirects someone's mail, which is exactly what a fraudster wants to do to someone else. The two accepted routes both verify identity in a way a fax cannot. Online, the Postal Service verifies you through a credit or debit card and a billing address check, and it charges a small identity verification fee. In person, you show photo identification at the counter and sign the form in front of a clerk. A fax carries a signature, but no live check that the signer is who they claim to be, and a faxed signature is easy to copy. That gap is why the Postal Service closed this route rather than leaving it open.
The same logic explains why mailed change-of-address forms also disappeared from the accepted list years ago for most cases. The old paper form, PS Form 3575, still exists at post offices, but you complete it and hand it in at the counter, in person, rather than mailing or faxing it in. The form did not vanish; the unsupervised channels for submitting it did.
| Route | Accepted? | How identity is checked |
|---|---|---|
| Online at usps.com | Yes | Card and billing address verification |
| In person at a post office | Yes | Photo ID shown at the counter |
| Fax | No | No live identity check, so not accepted |
| Mailing the form in | No, for most cases | Same problem as fax: no live check |
Go to the change-of-address section of the USPS website, enter your old and new addresses, and choose whether the move is permanent or temporary, for an individual, a family, or a business. You will be asked to verify your identity with a card, and the Postal Service will send a confirmation letter to both addresses. Keep an eye out for the confirmation at the new address: it contains a code you can use to edit or cancel the order online.
File before moving day if you can, and set the start date for the day mail should begin arriving at the new address. Filing late is the most common cause of a gap where mail goes to the old address with no forwarding in place. Forwarding also has a time limit, typically around a year for most first-class mail, so a change of address is a bridge, not a permanent fix: tell banks, employers, and government agencies your new address directly.
Take photo identification to any post office and ask for the change-of-address form, or complete it there at the counter. The clerk will check your ID, take the form, and process it. In-person filing suits people who cannot pass the online identity check, people filing for a business with paperwork the online form cannot handle, and anyone who wants a receipt from a clerk rather than an email confirmation.
One detail people miss: a change of address filed with USPS does not update the IRS, your state motor vehicle agency, your bank, or your voter registration. Each of those needs its own update, and some accept fax or mail even though USPS does not. Treat the USPS filing as step one, then work through the rest of the list in the first week after the move.
Watch out for lookalike websites that charge far more than the Postal Service for filing a change of address. The official route is the USPS website itself, and third-party sites that advertise change-of-address filing are selling a forwarding of your request, not an official channel. If a site asks for much more than the small verification fee, leave and go to usps.com directly.
