Your substitute P.O. box address provided by the Address Confidentiality Program (ACP) is an important tool to help keep your actual address private. This page explains how and where you can use your ACP address for everyday purposes, including mail, school enrollment, obtaining a driver’s license, voter registration, and more.

If you're looking for general information about the ACP, including eligibility and how to apply, please visit the main Address Confidentiality Program page. Our goal is to provide you with the tools and guidance you need to protect your privacy and stay safe.

For receiving mail

Once your application is approved, we’ll provide you an ACP card with your new substitute P.O. box address.  Your substitute address can receive:

  • First-class letters
  • Legal documents

The program cannot forward:

  • Magazines
  • Packages
  • Prescriptions (talk to your pharmacy about other options)

We forward your first-class mail and legal documents right away.

For school enrollment

Here's how to keep your address private at school:

  • Talk to a school administrator about your situation. They'll help you prove your child can attend without showing your real address.
  • Use the "Guidance and Affidavit" document from the Texas Education Agency (TEA) website to guide you through the process.

Important privacy tip: Schools usually share student information (like names and addresses) with the public as "directory information." You have the right to prevent this. Contact the TEA at (512) 463-9734 or visit their website.

We're also here to answer your questions about using your ACP address for school enrollment.

For driver’s license

To put your confidential address on your driver's license:

  • Visit your local Texas DPS driver's license office in person
  • Bring your ACP card
  • Ask for a change of address

For more information about required documents, visit the TxDPS website.

For voter registration

You have the right to:

  • Register to vote using your ACP address
  • Get mail-in ballots at your ACP address

For help with voter registration or voting questions:

For banking purposes and utilities

Banks and private companies (like utility companies) don't have to accept your ACP address, but many will if you explain your situation and provide the acceptance letter or participant card.
