You’re moving in as a couple, sharing a flat, or hosting a relative. Everyone receives mail in their name. If only one name appears on the mailbox, some mail may be returned with the note “unknown recipient.” To add multiple names, you just need to follow a few simple readability rules and choose the right medium.
Why each occupant should be listed on the mailbox
In a collective building, the postal service can discharge its obligation to deliver if no identifying information is available for the mailbox. In practical terms, an absent name on the mailbox means mail will be returned, including registered letters.
No law requires engraving all household names. The constraint is practical, not legal. The mail carrier doesn’t have time to guess who lives behind an anonymous or incomplete mailbox.
This concerns everyone: a partner with a different name, a roommate, an adult child returning home, or a hosted parent. As soon as someone receives mail addressed to them at this address, their name must be visible on the plaque. To find out how to add multiple names on a mailbox, a few formatting and medium precautions are sufficient.

Label, engraved plaque, or adhesive: which medium to choose
Before thinking about the text, consider the medium. It determines the available space and the durability of the inscription.
Paper or cardboard label
This is the quickest solution. Most standardized mailboxes have a name holder with a slot designed to slide in a label. You just need to print or write the names and then cut them to the right size.
The downside: paper yellows, ink fades. Outdoors, expect to replace it in a few months. To enhance durability, laminate the label or slide it under the transparent film of the name holder.
Engraved plaque
The engraved plaque remains the most durable medium. The text withstands the elements and does not fade. Common materials include PVC, aluminum, and plexiglass. PVC offers the best value for a typical residential use.
Attachment can be done with screws, double-sided adhesive, or magnets depending on the mailbox model. In a co-owned property, check the internal regulations: some residences require a uniform format and color for all plaques.
Cut adhesive
Individual adhesive letters allow you to compose names directly on the surface of the mailbox. This option offers great freedom in layout. The result is clean if applied carefully, but removal sometimes leaves glue residue.
Layout of the plaque with multiple names
You have chosen your medium. Now, organize the text so that it is readable at first glance.
- One name per line: separate each occupant on a distinct line. “Martin” at the top, “Duval” below. The mail carrier can identify both names effortlessly.
- Add the first name only if multiple people share the same last name in the building, or if you want to differentiate occupants of the same household.
- If space allows, indicate the apartment number or floor on an additional line. This information speeds up delivery, especially in large complexes.
- Keep a font size large enough to be read from arm’s length. A text that is too small defeats the purpose of the plaque.
In shared housing, the mention “Family” makes no sense. Simply list each roommate. Three names on three lines are clearer than a single name followed by “and roommates.”

Special cases: couple, blended family, temporary hosting
Couple with different names
Each name appears on its own line. No need for a hyphen between the two or a mention of “Mr. and Mrs.” The most effective format remains the name alone, possibly followed by the initial of the first name if space is tight.
Blended family
Children with a different last name from the parent they live with must also appear if they are adults and receive mail. For minors, mail usually arrives in the parent’s name, so this question rarely arises.
Temporary hosting
Even a temporary stay of a few months justifies adding the name. A student staying with a relative, a parent recovering: if administrative mail arrives at this address, the name must be included. A paper label is perfectly suitable for this temporary situation.
Installation and attachment on a standardized mailbox
Standardized mailboxes (built after 1979) have a designated space for the plaque. The name holder usually measures a few centimeters wide, enough for two to three lines of text.
- Before sticking or screwing anything, measure the available space. An oversized plaque will stick out from the name holder and eventually peel off.
- For adhesive attachment, clean the surface beforehand with a slightly damp cloth. Dust prevents the adhesive from sticking.
- Avoid drilling the mailbox if you are a tenant. Prefer double-sided adhesive or a name holder with a built-in slide.
In a house, the mailbox is often outside, exposed to the elements. A moisture-resistant material (PVC, aluminum) will prevent having to replace the plaque every year.
The choice of medium ultimately depends on the duration of occupancy and the type of housing. An engraved PVC plaque for a homeowner couple, a laminated label for a passing roommate. The goal remains the same: for each occupant to receive their mail without it being returned to sender.
