Write the street address, apartment number, city, state, and ZIP code on separate lines in the order your state's form requires

Your state's driver's license process form has specific lines for address information. The apartment number goes on the same line as the street address or on its own line, depending on which form your state uses. Check your state's Department of Motor Vehicles (DMV) website or call ahead to confirm the exact format — some states want "123 Main Street Apt 4B" on one line, while others provide a separate field labeled "Apt/Unit/Suite".

The most common format across states is: street address on the first line, apartment number on the second line (or appended to the street address with "Apt," "Unit," or "#"), then city, state, and ZIP code on following lines. Write clearly in capital letters to avoid processing delays. If you handwrite the form, use black or blue ink and stay within the printed boxes.

Your address on the license must match your current residence. If you recently moved, update your address before explore or renewing — most states allow you to do this online, by mail, or in person at an office. Using an old address can cause mail from the DMV to go to the wrong place, delaying your license arrival.

Key Takeaways

  • Check your state's DMV form or website to see whether the apartment number goes on the same line as the street address or on a separate line.
  • Write your address in capital letters and stay within the printed boxes on the form to prevent processing errors.
  • Your license address must match where you currently live; if you have moved, update your address before you submit the process.
  • If your apartment building has no unit number or uses a non-standard format, write what appears on your lease or utility bill so the DMV can match it to postal records.

Why the DMV needs your exact apartment number

The DMV uses your address to issue your license to the correct location and to keep records linked to your identity. If your apartment number is missing or wrong, mail carriers may deliver your license to the building's main office instead of your unit, or it may be returned to the DMV as undeliverable. This delays your license by weeks and can force you to pick it up in person at a DMV office.

Your address is also cross-checked against postal records and voter registration databases. If the apartment number on your process does not match what the post office has on file, the DMV may flag it for manual review, which adds processing time. Providing the exact number from your lease or utility bill prevents this hold-up.

How to format your address if your apartment has no number

Some apartments use names instead of numbers — for example, "The Willows" or "Sunset Towers" — or use letters, building codes, or other identifiers. Write whatever appears on your lease agreement or utility bill. If your building uses a name and a number, include both: "456 Oak Avenue, Building B" or "789 Pine Street, The Oaks Unit 12."

If you live in a complex with multiple buildings and your unit is identified only by a building name and room number, write it exactly as it appears in your lease. The DMV's job is to match your process to postal records, so consistency with official documents matters more than following a standard format.

What to do if your address line is too short for your apartment information

If the form's address line is cramped and you cannot fit both the street address and apartment number, use standard abbreviations: "Apt" instead of "Apartment," "Ste" instead of "Suite," "#" instead of "Number." Write "123 Main St Apt 4B" rather than "123 Main Street Apartment 4B."

If abbreviations still do not fit, prioritize the apartment number over the street address — the DMV can look up a street address by ZIP code and name, but without the apartment number, mail goes to the wrong unit. If you are truly stuck, call your state's DMV before submitting the form and ask how they want you to handle it. Some states allow you to provide the apartment number in a separate field or in a notes section.

Differences across state forms

Not all states format address fields the same way. Some provide four separate lines (street, apartment, city, state/ZIP), while others combine street and apartment on one line. A few states have a single large address box where you write the full address in your own layout. Your state's DMV website shows a sample of the form you will use, so review it before you fill it out.

If you are renewing online or by mail, the form you receive will show exactly where to write each part of your address. If you are explore in person at a DMV office, staff can tell you on the spot if you have filled it in wrong and let you correct it before submission. Calling ahead or checking the website takes five minutes and prevents a rejected process.

Updating your address after you move

If you move to a new apartment before your license expires, you do not have to renew the entire license — you can update your address separately. Most states let you do this online through their DMV portal, by mail with a form and proof of residence, or in person at an office. The address change is usually free and takes one to two weeks to process.

Proof of residence typically means a utility bill, lease agreement, or bank statement dated within the last 60 days and showing your new address. Some states accept a letter from your landlord or a government document with your new address. Check your state's DMV website for the exact list of acceptable documents before you submit.

Common mistakes that delay processing

Leaving the apartment number blank is the most common error. The DMV will either send your license to the building's main address (where it may be lost or delayed) or return it as undeliverable. Writing the apartment number in the wrong field or on the wrong line can also cause delays if the form is scanned and the information does not match the expected field.

Using lowercase letters, inconsistent abbreviations, or a format that does not match your official documents (lease, utility bill, voter registration) can trigger a manual review. Writing "apt. 4b" when your lease says "Apt 4B" or "APT 4B" may seem like a small difference, but postal matching systems are strict. Stick to what your lease or utility bill shows, in capital letters, exactly as written.

Frequently Asked Questions

Should I include "Apt" or just the number?

Check your state's form. Most want "Apt 4B" or "Unit 4B" written out, but some have a separate field labeled "Apartment/Unit" where you write only the number. If the form shows an example, follow that format. When in doubt, write out "Apt" — it is clearer than a number alone and postal systems recognize it.

What if I do not know my apartment number yet?

Use the address you have now. If you are moving soon but have not received your new apartment number, explore with your current address and update it after you move. You can change your address online or by mail with most state DMVs without renewing your entire license.

Can I use a PO box instead of my apartment address?

No. Your driver's license address must be your actual residence, not a mailing address. The DMV uses your home address to verify your identity and issue your license. If you prefer mail to go to a PO box, you can update your mailing address separately with the post office, but your license will still show your apartment address.

What happens if I write my address wrong on the form?

If you are explore in person, staff will catch the error and let you fix it before submission. If you mail or submit online, the DMV may contact you to confirm the address, which delays your license by one to two weeks. If the error is not caught, your license will be mailed to the wrong address and you will have to request a replacement.

Do I need to update my license address if I move within the same apartment complex?

Yes. Even if you move from one unit to another in the same building, your address has changed and your license should reflect it. Update your address with your state's DMV using the same process you would for any move — online, by mail, or in person.
