Random PIN Grid Generator

Used by developers, writers, and creators worldwide.

A random PIN grid generator gives you a fast, no-code way to produce batches of numeric PINs for scratch cards, vouchers, loyalty programmes, and bulk access code distribution. Set your PIN length (4–8 digits) and choose how many you need (up to 50), and the tool outputs a clean, printable grid in seconds. Small businesses running promotions, event organisers issuing entry codes, and developers seeding test fixtures all hit the same wall: writing throwaway scripts or wrestling with spreadsheet formulas just to get a list of numbers. This skips all of that. Each PIN is independently randomised, keeping collision rates negligibly low for typical small-batch runs.

How to use

  1. Choose your options above
  2. Click Generate
  3. Copy your result

Detailed instructions

  1. Set PIN Length to the number of digits your system or print template requires (4, 6, or 8).
  2. Set Number of PINs to the exact quantity you need, up to 50 per batch.
  3. Click Generate to produce the full PIN grid instantly on screen.
  4. Select all the output text and copy it, then paste into your spreadsheet, print template, or database seed file.
  5. For batches over 50, repeat the process and use a spreadsheet COUNTIF to check for duplicates across combined batches.

Use Cases

  • •Printing 8-digit PINs onto physical scratch card batches for a promotional campaign
  • •Issuing unique 6-digit access codes to paid webinar registrants via a mail-merge template
  • •Seeding a voucher redemption table in a staging database with realistic PIN fixtures
  • •Generating locker reset codes in bulk for a gym or office facilities team
  • •Creating one-time 4-digit entry codes for a ticketed pop-up or charity prize draw

Tips

  • →Use 6-digit PINs for vouchers distributed digitally — they balance memorability with enough randomness to prevent casual guessing.
  • →When pasting into Excel, pre-format the destination column as Text so leading zeros in codes like 0482 are not silently dropped.
  • →Generate a batch 10-15% larger than you need, then discard any that look too patterned (like 1111 or 1234) to avoid user suspicion.
  • →If you need PINs to look distinct on printed cards, regenerate any batch that contains three or more codes starting with the same digit.
  • →Pair this generator with a simple mail-merge template in Word or Google Docs to print individualised scratch cards or vouchers without custom software.
  • →For developer testing, generate a batch of 8-digit PINs and store them as a fixture file — it is more realistic than sequential dummy data and catches off-by-one formatting bugs.

FAQ

how do I generate bulk PINs for scratch cards without duplicates

Set PIN Length to 8 (standard for most scratch card designs) and Count to your print run size, up to 50 per batch. For larger runs, generate multiple batches and paste them into a spreadsheet, then use a COUNTIF formula to flag any collisions before sending to print.

are randomly generated PINs safe enough for real vouchers or gift cards

For promotional vouchers, event entry codes, and low-value gift cards, yes — the collision probability for a batch of 50 six-digit PINs is under 0.01%. For anything with significant financial value or strict security requirements, use a server-side cryptographically secure generator and add a deduplication check in your own system.

what PIN length should I use — 4, 6, or 8 digits

4 digits works for low-stakes uses like locker combos or raffle entries. Use 6 digits for discount vouchers or event check-in codes where casual guessing is a real risk. Reserve 8 digits for gift cards or one-time-use codes with financial value attached.
