PIN Grid Generator

Used by developers, writers, and creators worldwide.

A PIN grid generator lets you create batches of numeric PIN codes in seconds, replacing tedious manual work when you need codes for scratch cards, event badges, loyalty vouchers, or access control systems. Set the count up to 50 and the digit length from 4 to 8 to match your security requirements. A 4-digit PIN gives 10,000 combinations — fine for raffle tickets or Wi-Fi codes. Six digits hits one million, suitable for loyalty programs. Eight digits is appropriate for staff credentials or physical keypad panels. All generation runs in your browser; nothing is sent to a server or logged anywhere.

  2. Click Generate
  3. Copy your result

Detailed instructions

  1. Set the Number of PINs field to how many codes you need, between 1 and 50.
  2. Set the PIN Length field to match your security requirement: 4 for basic uses, 6 or 8 for higher security.
  3. Click the generate button to produce the full PIN grid instantly.
  4. Review the numbered grid, then use Ctrl+P to print or select-all to copy the codes into a spreadsheet.

Use Cases

  • •Printing 50 PIN-backed scratch cards for a retail promotional campaign
  • •Generating 6-digit temporary access codes for event staff badge sheets
  • •Seeding a staging database with realistic numeric PINs for Cypress login tests
  • •Producing sequentially numbered raffle ticket codes for a charity fundraiser
  • •Assigning unique 4-digit locker codes for a gym or co-working space rollout

Tips

  • →Use 6-digit PINs for printed vouchers — they're long enough to deter guessing but short enough to type without errors.
  • →When pasting into Excel or Google Sheets, format the destination column as Text first to preserve leading zeros on codes like 0031.
  • →Generate 20% more PINs than you need, then deduplicate in a spreadsheet — this is faster than re-running the generator if you spot a collision.
  • →Number the printed grid before cutting individual slips so you can reconcile which codes were distributed and to whom.
  • →For access badge systems that expire codes weekly, generate a fresh batch each Monday and keep a dated archive in a locked spreadsheet.
  • →Test a small batch at 4 digits and a separate batch at 8 digits side by side to decide which length feels appropriate for your users before printing at scale.

FAQ

what pin length should i use for staff access badges

Six digits is the practical minimum for keypad entry and staff badges — 4-digit codes are too easily shoulder-surfed. If codes are printed and never memorized, bump to 8 digits for higher-turnover or higher-risk environments. This generator lets you set any length between 4 and 8 to match the requirement.

are the generated pins random enough for security use

The tool uses JavaScript's Math.random(), which produces statistically unpredictable output suitable for vouchers, event tickets, scratch cards, and test data. It is not cryptographically secure — for bank card PINs or authentication tokens, use a tool based on the Web Crypto API instead.

how do i stop spreadsheets from dropping leading zeros when i paste pins

Format the destination column as plain text before pasting. In Excel, select the column, press Ctrl+1, and choose Text. In Google Sheets, go to Format → Number → Plain text. This tells the spreadsheet to treat the values as strings, preserving codes like 0042 exactly as generated.
