Hungary irányítószám validator
How the irányítószám format works
- Format
- 4 digits
- Example
- 1051
Things to watch for
- Format-only check — does not confirm the irányítószám actually exists
- Always exactly 4 digits with no separators
- Every Budapest code starts with 1; the next two digits identify the kerület (district) number
^[0-9]{4}$A Hungarian irányítószám is the 4-digit postcode Magyar Posta uses to route mail, written directly before the city name — for example 1051 Budapest. The system dates to 1973, and inside Budapest it’s genuinely hierarchical: every code starts with the digit 1, the next two digits identify one of the capital’s 23 kerület (districts), and the final digit narrows delivery within that district. Anyone validating a Hungarian shipping address, a checkout form, or a spreadsheet of customer records needs the irányítószám in the correct 4-digit shape before it’s trusted.
Because it’s a bare run of digits with no separator, a transposed digit routes to a genuinely different district rather than producing something obviously malformed — the kind of error a shape check catches even before a district lookup would.
How this validator works
This tool checks that the input is exactly 4 digits with no letters, spaces, or hyphens, entirely in your browser, with nothing sent to a server.
What a pass doesn’t tell you
An irányítószám carries no check digit, so matching the 4-digit shape is the most a client-side tool can confirm — not that Magyar Posta has assigned it to a real district. Confirming that requires Magyar Posta’s own postcode lookup.
Scope: this page and tool cover format validation only — not address lookup or confirming an irányítószám is currently in use.
irányítószám FAQ
What does irányítószám mean, and how many digits does it have?
Irányítószám literally means 'directing number' — Hungary's 4-digit postcode, introduced in 1973. It's written directly before the city name, e.g. 1051 Budapest.
What do the digits of a Budapest irányítószám encode?
Every Budapest code begins with 1. The next two digits identify the kerület — one of the city's 23 numbered districts — so 1051 names district V (Belváros-Lipótváros), the historic centre. The final digit narrows things further within that district.
Does a correctly formatted irányítószám mean it actually exists?
No. This tool only confirms the string is 4 digits — it doesn't check it against Magyar Posta's actual assignment list. Confirming an irányítószám is real, and seeing which district it names, requires Magyar Posta's own postcode lookup.
