You can use a virtual address for an EIN application, but only on the mailing address line of Form SS-4. The form has a second address field for the entity’s physical street location, and that line does not accept P.O. boxes and is a poor fit for mail-only virtual services. Getting the two lines straight is what separates a clean application from one that gets flagged or rejected.
The Two Address Fields on Form SS-4
Form SS-4 asks for your address twice, and the two lines are not interchangeable.
Lines 4a and 4b are the mailing address. This is where the IRS sends correspondence, and the instructions simply tell you to “enter the mailing address for the entity’s correspondence.” A virtual address, a P.O. box, or a mail forwarding service is acceptable here.
Lines 5a and 5b are the street address, meaning the entity’s physical location. The instructions state directly: “Don’t enter a P.O. box number here.” You only complete these lines if your physical location differs from your mailing address. If mail and operations happen at the same place, such as a home office, you fill in 4a and 4b and leave 5a and 5b blank.1Internal Revenue Service. Instructions for Form SS-4 (Rev. December 2025)
So the short version: a virtual address is fine on 4a/4b. The question is what you put on 5a/5b if the IRS asks for a physical location and you don’t have one.
Does a Virtual Office Count as a Physical Address?
The IRS instructions prohibit “a P.O. box number” on the street address line. They do not explicitly mention virtual offices, coworking spaces, or commercial mail receiving agencies (CMRAs). A virtual office that assigns you a suite number at a real building is technically a street address, not a P.O. box, and that distinction matters.
The practical issue is that these addresses are often recognizable. The U.S. Postal Service requires every CMRA address to include either a “PMB” (Private Mailbox) identifier or a “#” symbol before the box number. The words “P.O. Box” are not permitted, but the PMB designation itself signals that the address belongs to a commercial mail service rather than a dedicated office.2United States Postal Service. 285 Private Mailbox Addresses – Postal Explorer IRS staff or systems that recognize that pattern can flag the application for review.
Some virtual office plans include more than a mailbox. If your service gives you actual access to a physical workspace, even part-time, the argument that it qualifies as a legitimate business location is stronger. A bare mail-forwarding address with no workspace is harder to defend. The safer entries on 5a and 5b are a home office, leased commercial space, or a coworking membership that provides a real physical presence.
What the IRS Accepts Isn’t What Your Bank Will Accept
Even if the IRS processes your EIN with a virtual mailing address, your bank almost certainly won’t open an account with one. Federal anti-money-laundering rules require financial institutions to collect a residential or business street address for every account holder under their Customer Identification Program. A post office box does not satisfy that requirement.3Financial Crimes Enforcement Network. Customer Identification Program Rule – Address Confidentiality Programs Banks routinely reject virtual addresses and mail forwarding services for business accounts. Plan on producing a physical address at account opening regardless of what appears on your Form SS-4.
State law adds another layer. Most states require every LLC and corporation to maintain a registered agent with a physical street address in the state of formation. That’s the address for service of lawsuits and government notices. A registered agent service can fill this role, with annual fees generally running from about $100 to $300 depending on the state and provider; some formation services include the first year free. The registered agent’s address satisfies the state requirement but is separate from the address the IRS has on file, and updating one does not update the other.
The upshot: even a solo owner working from home usually needs to keep three addresses coordinated: what the IRS has, what the bank has, and what the state has. A virtual address rarely works for all three.
Changing Your Address Later
If your situation changes after you get the EIN, whether that’s a new mailing address, a new physical location, or a new responsible party, the IRS uses Form 8822-B to update its records. The form covers all three situations.4Internal Revenue Service. About Form 8822-B, Change of Address or Responsible Party – Business
One deadline is firm: a change of responsible party must be reported within 60 days. Address changes have no explicit deadline but should be filed promptly so IRS notices actually reach you. Processing generally runs four to six weeks.5Internal Revenue Service. Form 8822-B Change of Address or Responsible Party — Business
If the issue is a mistake on your original application rather than a change, don’t submit a new EIN application. Send a letter on company letterhead explaining the error, including the responsible party’s name and SSN, the full legal business name, the correct EIN, your mailing address, and the specific information to be corrected. Call 800-829-4933 (Monday through Friday, 7 a.m. to 7 p.m. ET) to confirm which IRS office should receive the letter.
Risks of Listing an Address You Don’t Actually Use
Form SS-4 is signed under penalties of perjury. Deliberately listing an address where the business has no legitimate presence is not a gray area. Federal law treats willfully false statements on tax documents as a felony, carrying fines up to $100,000 for individuals ($500,000 for corporations) and up to three years in prison. In practice, the IRS is much more likely to reject the application, delay processing, or flag the account for review than to pursue criminal charges over an address. The legal exposure still exists, and it isn’t worth the risk when legitimate options are available.
The more common consequence is quieter: missed correspondence. If the IRS sends a notice to an address you don’t actually monitor, filing deadlines, penalty notices, or audit letters can pass you by. By the time you notice, penalties and interest may have been running for months. Whatever address ends up on your form, use one where mail reliably reaches you.
