Every prize tier of the Taiwan uniform invoice lottery is anchored on the First Prize numbers — matching their last 3 digits already wins the Sixth Prize (NT$200), and matching more trailing digits upgrades the tier (4 digits = Fifth Prize NT$1,000, up to all 8 digits = First Prize NT$200,000). So the last 3 digits are enough to tell whether a receipt can win at all; this tool then guides you to verify more digits when needed.

The Special Prize (NT$10 million) and Grand Prize (NT$2 million) only pay out on a full 8-digit match — unlike the First Prize numbers, they carry no partial-match minor prizes. If only the last 3 digits match, the receipt wins nothing from these two numbers, which is why this tool marks such a hit as "possible" and asks you to verify all 8 digits.

Numbers are transcribed from the official announcement of Taiwan's Ministry of Finance after each draw (the 25th of every odd month) and cover the periods still within their claim window. If a newer draw has happened before this tool is updated, an honest notice appears instead of passing off old numbers as current.

No. The winning numbers are built into the page, and your digits are matched entirely inside your browser — the tool sends no network request with your input and stores nothing after you leave.

First confirm the receipt belongs to the same prize period (year and months are printed on it), then claim within the official window shown for that period — at post offices, convenience stores or banks per Ministry of Finance rules, bringing your ID for larger prizes. Note that prizes above certain amounts are subject to tax withholding. Always follow the official announcement.

Taiwan prints a lottery number on every official receipt (uniform invoice) to encourage consumers to ask for receipts. Every two months the government draws winning numbers, with prizes from NT$200 up to NT$10 million. This tool is specific to Taiwan's system — receipts from other countries have no such numbers.
