How to Pick a Random Winner for Your Online Raffle
You have sold the tickets, collected the entries, and now comes the moment every raffle organizer dreads: picking a random winner in a way that participants will actually trust. A poorly documented draw can attract accusations of bias, refund demands, and reputational damage that outlasts any prize you offered. This guide covers every method available in 2026, from free manual tools to fully automated raffle software, so you can choose the approach that fits your situation and defend your draw if anyone ever questions it.
Why Fair Random Winner Selection Matters
In most jurisdictions, a raffle or lottery is a regulated activity. The winner must be selected by chance, not by organizer discretion. In the United States, the Federal Trade Commission requires that sweepstakes and contests disclose odds and select winners through a genuinely random process. The UK Gambling Commission imposes similar standards on paid-entry prize draws. Failing to pick a winner randomly, or failing to document that you did, can expose your organization to fines and legal challenges.
Beyond legal compliance, fairness builds the trust that turns a one-time raffle buyer into a repeat customer. According to a 2024 consumer trust survey by Trustpilot, 68% of online shoppers say they would not participate in a future promotion from a brand that appeared to rig a previous one. The draw method you choose is also a marketing decision.
The 4 Main Methods to Pick a Random Winner
Each method below has legitimate use cases. The right choice depends on your entry volume, your budget, and how much auditability you need.
1. Dedicated Raffle and Giveaway Platforms
Platforms built specifically for raffles handle the draw automatically and typically produce a timestamped, auditable record. ReviewRaffles, for example, integrates directly with WooCommerce. When your raffle closes, the platform pulls every paid ticket entry and runs a certified random selection algorithm without any manual intervention. The winner record, including the ticket number, entry timestamp, and selection timestamp, is stored in your WordPress dashboard for reference. This is the most defensible approach for paid-entry raffles.
Other platforms such as Gleam, Rafflecopter, and Woobox offer similar automation for free-entry giveaways. See our comparison of the best online sweepstakes and giveaway tools for 2026 for a detailed breakdown of features and pricing.
2. Random Number Generators (RNGs)
If you assign each entry a sequential number (ticket 1 through ticket 500, for example), you can use a random number generator to pick the winning number. RANDOM.ORG is the most widely cited option because it derives randomness from atmospheric noise rather than a pseudo-random algorithm, making it statistically superior for prize draws. The site generates a shareable URL for each result, which you can post publicly as proof.
Google also has a built-in random number generator. Searching "random number between 1 and 500" in Google returns an instant result, though it does not produce a permanent shareable record.
3. Spreadsheet Formulas
For small organizers managing entries in a Google Sheet or Excel file, the RAND() and RANDBETWEEN() functions can assign a random sort key to each row. Sorting the sheet by that column and picking the top result is a legitimate random selection. The main weakness is that the random values recalculate every time the sheet is opened, so you must take a screenshot or lock the values immediately after the draw.
In Google Sheets, the formula to assign a random rank to each entry is: =RANK(RAND(), A:A). Paste-as-values immediately after running to freeze the result.
4. Physical Draws (Documented)
For in-person events or community raffles, a physical drum draw is still perfectly valid, provided you record it. Livestreaming the draw on Facebook Live, Instagram Live, or YouTube adds an independent timestamp and a public witness record. The video should show the total number of tickets in the drum before drawing. If you sell tickets online and hold a physical draw, announce the draw date and time in advance so participants can watch.

How ReviewRaffles Automates Random Winner Selection on WooCommerce
Running a raffle through WooCommerce without dedicated software means manually tracking ticket purchases in order notes, exporting a CSV, running a random number generator, and then manually notifying the winner. That process takes hours and introduces human error at every step.
ReviewRaffles is a WooCommerce plugin that replaces every one of those manual steps. Here is what the automated workflow looks like:
- Ticket sales as WooCommerce products. You create a raffle product in WooCommerce as you would any other product. ReviewRaffles adds ticket quantity limits, a draw date countdown, and a remaining-ticket counter automatically.
- Entry ledger built in real time. Every completed purchase writes a unique ticket number to the raffle entry ledger stored in your WordPress database. No manual CSV export needed.
- Automated random draw at close. When the draw date arrives, ReviewRaffles selects a random winner using a cryptographically secure random number generator seeded by system entropy, equivalent in randomness quality to RANDOM.ORG. The selection runs server-side without any organizer input.
- Timestamped winner record. The winning ticket number, the buyer's name, the draw timestamp, and the total entry count are all stored in the plugin's winner log. You can export this as proof at any time.
- Automated winner notification. The winner receives an automated email with redemption instructions. No manual outreach required.
For store owners already selling products on WooCommerce, this means running a raffle requires no additional technical setup. You are simply adding a new product type to a store you already manage.

Best Practices for a Transparent Random Winner Draw
Regardless of which method you use, the following practices protect you legally and build participant trust.
Publish Official Rules Before the Raffle Opens
Your official rules should specify the draw date, the draw method, how the winner will be notified, and how long the winner has to claim the prize. Publishing these before ticket sales open means participants consent to the process at the point of entry. This is a legal requirement in most US states and Canadian provinces for any paid-entry raffle.
Document the Total Entry Count Before Drawing
Record the total number of eligible entries immediately before running the draw. If you use ReviewRaffles, this figure appears in the winner log automatically. If you use a manual method, screenshot your entry list with a timestamp before generating the random number. This prevents any suggestion that entries were added or removed after the draw.
Announce the Winner Publicly
Post the winner's name (with their consent) or their ticket number on the same channel where you promoted the raffle. This closes the loop for all other participants and demonstrates the draw took place. If a participant queries the result, you can point them to the public announcement and, if needed, share the draw record.
Have a Backup Winner Process
Specify in your rules what happens if the winner cannot be reached within a set period (typically 14 to 30 days). Drawing a backup winner from the same pool using the same method and documenting it identically is the cleanest approach. ReviewRaffles allows you to run a secondary draw from the existing entry pool with one click.
Avoid Disqualifying Entries After the Draw
If you need to disqualify ineligible entries (for example, entries from outside an eligible geographic area), do this before running the draw, not after. Disqualifying entries after the draw has already generated a winner number creates an auditing problem and looks like manipulation, even when it is entirely legitimate.
Common Mistakes That Undermine Raffle Credibility
These are the errors that generate complaints and refund requests most often.
- No documented draw record. If you cannot show how the winner was selected, you cannot defend the result. Always save a screenshot, video, or system log.
- Drawing before the close date. Running the draw early, even by accident, invalidates all entries submitted after the draw ran. Use a platform that enforces the draw date automatically.
- Manual selection from a visible list. Scrolling through a list of names and picking one is not a random draw, regardless of your intent. Use a mechanical or algorithmic method.
- Not notifying all participants of the result. Participants who purchased tickets are entitled to know the outcome. An email to all entrants, or a public post, satisfies this expectation.
- Relying on social media platform tools for paid-entry draws. Instagram's comment picker and similar tools are appropriate for free-entry giveaways. For paid-entry raffles, you need a tool that produces an auditable record tied to the payment transaction.
