Sooner or later a US form asks for a "US address". Sometimes it's a real residential address, as for a bank's know-your-customer (KYC) check or a credit card. Sometimes it only needs to be somewhere mail can be delivered, as for a debit card, tax letters or an LLC's documents. Knowing which one the form wants will save you most rejections.
This guide compares the three legitimate options: a virtual mailbox, a friend's or family member's address (with their consent), and a registered agent address. It walks through USPS Form 1583 and lists where each option works.
The three options
| Virtual mailbox (CMRA) | Friend's or family's address | Registered agent address | |
|---|---|---|---|
| What it is | Commercial mail-receiving agency that scans and forwards your mail | A real home, used "c/o" with permission | Address that accepts legal papers for your US company |
| Typical cost (Sept 2026) | About $10–35/month | Free | About $25–300/year |
| Receives your personal mail | Yes | Yes | Usually only legal and state mail |
| Accepted as a residential address | Usually no | Only if you actually live there | No |
| Accepted as a company mailing address | Often yes | Sometimes | Rarely (many banks reject it) |
| Best for | Debit cards, statements, IRS letters, LLC mail | Receiving cards and parcels during a visit | The state-required agent for your LLC |
Virtual mailboxes
Services such as Anytime Mailbox, iPostal1, US Global Mail and Earth Class Mail give you a street address with a unit or "PMB" number. They scan envelopes, open and scan contents on request, and forward parcels internationally. As of September 2026, entry plans start around $9.99/month. The price depends heavily on the location you pick, and scanning, forwarding and notarization cost extra. Check each provider's pricing page before signing up.
USPS Form 1583
A virtual mailbox is legally a Commercial Mail Receiving Agency (CMRA). USPS rules require you to authorize it to receive mail for you by signing PS Form 1583.
- Pick a provider and location. Choose a real street address in a state that suits you. Some states, like Delaware and Wyoming, are popular for LLCs.
- Complete Form 1583. Most providers pre-fill it in their dashboard. List everyone (and, for a business, the company) who will receive mail.
- Provide two IDs. Under USPS rules updated in July 2023, you need one government photo ID (a passport) plus a second ID from the accepted list. Utility bills and corporate ID cards no longer count.
- Sign in front of a notary or the CMRA. Non-residents usually use remote online notarization (RON). Most providers offer an integrated online notary for a fee (often around $25), or accept an electronically notarized PDF where state law allows it.
- Wait for approval. The provider uploads your details to the USPS CMRA customer database. Mail can be held until approval.
Where virtual mailbox addresses get rejected
USPS flags CMRA addresses, and many companies screen for them automatically.
- Banks' residential address fields. Most US banks and card issuers need your real residential address, which may be your foreign home address. A mailbox address there often triggers a decline or extra checks.
- Mercury: doesn't accept registered agent addresses, P.O. boxes or UPS Store addresses as the company's physical address.
- Relay: requires a physical US address with no P.O. boxes and no virtual mailboxes for beneficial owners, according to its help centre.
- Credit card applications that ask for your home address.
- Some marketplaces and payment processors require a verifiable operating address for your business.
Mailboxes usually work as a mailing address. That covers receiving a debit card, bank statements, IRS notices such as an EIN letter or ITIN approval, and your LLC's mail.
A friend's or family member's address
This is fine as a "care of" (c/o) mailing address if they agree. Examples: having a debit card sent there during a trip, or receiving a parcel. It's not your residence unless you actually live there. Also consider that they'll receive sensitive financial mail, and you depend on them to forward it.
Registered agent address
Every US LLC must name a registered agent in its state of formation to receive legal papers ("service of process"). Formation services include the first year. The agent's address:
- Is what appears on public state filings, which keeps your home address private.
- Is not a mailbox for everyday mail. Many agents reject or charge for non-legal mail.
- Is often rejected as a business address by banks such as Mercury.
For business banking, most founders pair the registered agent (for the state) with a virtual mailbox or real office (for mail) and their real residential address abroad (for KYC).
Recommended setups
| You need... | Use |
|---|---|
| A debit card or checkbook delivered | Virtual mailbox with international forwarding |
| KYC residential address | Your real home address (foreign is fine for most non-resident products) |
| LLC public address | Registered agent |
| LLC mail (IRS, bank letters) | Virtual mailbox |
| One-off delivery during a US trip | Hotel (ask first) or a friend's address, c/o |
Pitfalls
- Choosing the cheapest location without checking forwarding fees. International parcel forwarding often costs more than the monthly plan.
- Letting the mailbox lapse. You'll miss IRS notices, including Form 5472 penalty letters.
- Using a mailbox as your "home" on a bank application. It's the most common cause of an automated decline.
- Not reading scanned mail. Some banks send verification codes or card-activation letters only by post.
