Malta Postal Code validator
How the postal code format works
- Format
- 3 letters + 4 digits, written as AAA NNNN (e.g. VLT 1117)
- Example
- VLT1117
Things to watch for
- Format-only check — does not confirm the postal code actually exists
- The 3-letter prefix identifies the locality (VLT = Valletta), not a postal zone within it — it's a completely different letter set per town
- In use since 2007; the 4 digits after the locality code narrow down to a street or building
^[A-Z]{3}[0-9]{4}$A Maltese postal code is the code MaltaPost has used since 2007, combining a 3-letter locality abbreviation with 4 digits — for example VLT 1117 for an address in Valletta. Unlike most letter-and-digit postcodes, where letters encode a numeric-style zone, Malta’s 3 letters are a locality name in miniature — a completely different letter combination per town — while the 4 digits after it narrow down to a specific street or building within that locality. Anyone validating a Maltese shipping address, checkout form, or spreadsheet of customer records needs the letters and digits both present and correctly ordered before it’s trusted.
A common mistake is entering only the 4 digits without the locality letters, or the reverse — since neither half alone identifies a valid Maltese address, and mixing up which comes first produces a string this format won’t match.
How this validator works
This tool checks that the input is exactly 3 letters followed by exactly 4 digits, with any space between them stripped before checking, entirely in your browser — nothing is sent to a server, and there’s no signup.
What a pass doesn’t tell you
A Maltese postal code carries no check digit, so matching the letter-then-digit shape is the most a client-side tool can confirm — not that MaltaPost has assigned it to a real street. Confirming that requires MaltaPost’s own postal code lookup.
Scope: this page and tool cover postal code format validation only — not address lookup, locality-letter verification, or confirming a code is currently in use.
postal code FAQ
What do the 3 letters in a Maltese postal code mean?
They abbreviate the locality, not a postal zone — VLT identifies Valletta, for example. Malta has 114 localities, and each one gets its own distinct 3-letter code, so the letters function more like a place-name abbreviation than the numeric routing prefixes used elsewhere.
Do I need to type a space between the letters and digits?
No — this validator accepts the code with or without the space (e.g. 'VLT1117' or 'VLT 1117'). The space is a formatting convention; the underlying code is always 3 letters followed directly by 4 digits.
Does a correctly formatted postal code mean it actually exists?
No. This tool only confirms the string matches 3 letters followed by 4 digits — it doesn't check it against MaltaPost's actual assignment list. Confirming a code is real requires MaltaPost's own postal code lookup.
