Thank you for choosing Americas Mailbox

We're very close to opening your account and taking care of your mail forwarding needs.

Please Note:
You MUST have an account with us BEFORE having any mail sent to us, or else we are REQUIRED by the post office to mark it "Return to Sender" and send it back. If you want to register your vehicle, it is often a good idea to open your account BEFORE registering--or even before buying--to take advantage of South Dakota's low taxes. Dealers in a few states may have requirements as to how long you must be a resident of another state before you can avoid paying sales tax on a purchase; check with your current state's dealers to make sure you meet their requirements.

Next Steps

Step 1 - Submit Your Paperwork

All that's left is some paperwork. Scroll down this page to find the links you need.

We need several forms from you to open your account. Please don't hesitate to call us if you need help filling any of these in. You MUST download the complete application kit here, which includes all the forms you need plus instructions. If you have any problems at all downloading the Application Kit, please give us a call at (605) 388-2143 or email us at office@americas-mailbox.com and we'll get one out to you quickly.

If you would like an appointment with a Membership Specialist in our office to complete the paperwork, just call M-F 9-5 to set that up. It takes less than an hour to handle this in person.

If you wish to QUICKLY get South Dakota driver's licenses, you may make the necessary appointment FIRST with the South Dakota Department of Public Safety, even before we assign you your address. You will need to have become a member before changing your driver's license.

Please submit the following forms to: office@americas-mailbox.com or Americas.Mailbox@GMail.com

       or - download only the parts you need as additional copies:

  • US Postal Service Form 1583 with written instructions  - This is what gives us permission to accept your mail. This is NOT what tells the US Postal Service to forward your mail to us--you have to do that at your local post office.
  •  Mail Service Agreement - This is the 3-page document with which you pay and join Americas Mailbox as your first step.
  •  Power of Attorney - This only gives us authorization to apply for your title and registrations on your behalf - nothing else. You only need to fill this out if you want us to register your vehicle. PLEASE NOTE: The Power of Attorney MUST be notarized! It must be free of any erasures or cross-outs. If it is not correct, you must do it over, causing unnecessary delays and cost.

Step 2 - Process Payment and Activate Account

One of our customer service representatives will get back to you within 2 business days of receiving your paperwork to help you activate your account and process your payment.

Usually, your account is activated within 1 - 2 business days of receiving your paperwork. However, if you'd like (and you include your request in writing when you send us the application with a specific date listed up to 30 days in the future), we'll even process the paperwork you send us, charge your account, but not activate your account until the date that you specify. However, when we receive the first piece of mail or package for you the account, of course, would begin on that date regardless of any prior request. This way, you can start telling whoever sends you mail your new address right away and start getting things set up. So far as we know, Americas Mailbox is the only company in the country willing to do that for you. 

If you wish to re-open any closed account, or add someone to your existing account:
Please download a new Mail Service Agreement and Post Office 1583 form(s). Fill those out and send them in with the required IDs, filling in your SAME PMB number. That number is yours forever.


If you are registering a vehicle through Americas Mailbox

If you will be using your new South Dakota address for vehicle registrations and South Dakota driver's licenses, we recommend that as soon as you receive your address from us, you immediately start changing your billing address with credit cards and bank accounts. This will show your intent to the vehicle insurance companies that you are becoming a full-time traveler.

It doesn't take very long to open an account with us or to get your license plates once the paperwork is in place. But please, don't wait until the last moment to do this.  Have us set up your account first.

  • Vehicle Registration Checklist - Download these pages to learn what information Americas Mailbox needs from you to fill out all the paperwork to register your vehicles for you.
  • Power of Attorney - This only gives us authorization to apply for your title and registrations on your behalf - nothing else. You only need to fill this out if you want us to register your vehicle. PLEASE NOTE: The Power of Attorney MUST be notarized! It must be free of any erasures or cross-outs. If it is not correct, you must do it over, causing unnecessary delays and cost.

Other forms you may need to fill out to allow us to complete your vehicle registration:

  •  Verification of Tax Paid to Another State - Ask our vehicle registration department if this form will be necessary for you. You simply need to fill it in and sign it.
  •  General Affidavit - If we tell you that you need to make a statement of fact regarding your registration, use this form.

Please read this important note if you would like us to register your vehicles.
