How the postal code format works
- Format
- 6 digits
- Example
- 100000
Things to watch for
- Format-only check — does not confirm the postal code actually exists
- Always exactly 6 digits with no separators
- Kept the same Soviet-era six-digit index length as Russia and Kazakhstan — Tashkent's central code is 100000
^[0-9]{6}$An Uzbek postal code is the 6-digit code Uzbekiston Pochtasi uses to route mail — for example 100000 for Tashkent. The six-digit length is a direct holdover from the Soviet postal indexing system introduced in 1971, kept unchanged after Uzbekistan’s independence in 1991 — the same choice Kazakhstan and Russia both made for their own postal codes. Anyone validating an Uzbek shipping address, a checkout form, or a spreadsheet of customer records needs the code in the right 6-digit shape, leading zeros included where they appear, before it’s trusted.
Because it’s a bare run of digits with no separator, a single dropped or transposed digit produces a code that’s still superficially plausible, with nothing about its shape flagging the mistake.
How this validator works
This tool checks that the input is exactly 6 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 Uzbek postal code carries no check digit, so matching the 6-digit shape is the most a client-side tool can confirm — not that Uzbekiston Pochtasi has assigned it to a real city or delivery office. Confirming that requires Uzbekiston Pochtasi’s own postcode lookup.
Scope: this page and tool cover format validation only — not address lookup or confirming a code is currently in use.
postal code FAQ
Why does Uzbekistan use a 6-digit postal code?
It inherited the Soviet Union's six-digit indexing system, introduced across the USSR in 1971, and kept the same digit length after independence in 1991. Neighboring Kazakhstan and Russia both run the same six-digit length for the same historical reason.
What is Tashkent's postal code?
100000, for the city center.
Does a correctly formatted postal code mean it actually exists?
No. This tool only confirms the string is 6 digits — it doesn't check it against Uzbekiston Pochtasi's actual assignment list. Confirming a code is real, and seeing which city it covers, requires Uzbekiston Pochtasi's own postcode lookup.
