House numbers with letters

Why choose a house number with a letter?

A letter attached to a number is often necessary when several dwellings share the same street position, for example after the subdivision of a plot or the construction of an independent annex. It allows postal services, delivery drivers, and emergency services to precisely identify the correct access, without confusion with the neighboring house. It is also a solution used for buildings with multiple entrances, where each door receives a number followed by a distinct letter.

This configuration is also found in some recent housing developments, where several houses built on the same former plot retain the original number supplemented by a letter for each new parcel. Clear addressing from the time of construction subsequently avoids any confusion for visitors and official services alike.

How to combine numbers and letters on your facade?

For clear legibility, the letter generally uses the same size and finish as the number that precedes it, in order to form a visually coherent set. It is positioned directly after the last digit, without excessive spacing, so that the address reads as a whole. If your facade already displays several digits, take care to maintain a regular horizontal alignment between the numbers and the letter for quick reading from the street.

What font style should you choose for a number with a letter?

The font of the number and the letter must remain identical to avoid any visual disruption in the address. A font with clean lines suits the majority of contemporary facades, while a more classic font blends better with traditional architecture. We do not offer letter-by-letter customization: each reference is available in a consistent character set, including both numbers and letters.

Should you notify your town hall if you add a letter to your number?

The assignment of the number and its associated letter is generally the responsibility of the municipality, particularly during a plot subdivision. It is recommended to check with your town hall that the number-letter combination is the one officially registered before ordering your number, in order to avoid any postal addressing errors.

Is a number with a letter also suitable for grouped mailboxes?

In grouped housing or small apartment buildings, each mailbox generally features the number and letter of its unit, to remain consistent with the number displayed on the facade. Using the same finish on the mailbox and on the door number reinforces the clarity of the whole, especially for delivery drivers who must quickly identify the correct recipient among several similar addresses.
