How to Read a Durex Lot Number (Expiration & Batch Code Guide)

A Durex lot number (or batch code) is a 6-8 character alphanumeric string printed on the packaging. The first 2-4 digits often indicate the manufacture date (year/month or month/year), while the remaining characters identify the production batch. Expiration is typically 3-5 years from manufacture-check the separate "EXP" date if available.

Where to Find the Lot Number

  • Foil wrapper: Printed near the barcode or edge.
  • Box: On the bottom, side panel, or near the expiration date.
  • Individual sachet: Often on the back or sealed edge.

How to Decode the Lot Number

Format 1: YYMM + Batch (Most Common)

  • Example: 2305AB12
  • Breakdown:
    • 23 = Year 2023
    • 05 = May (month)
    • AB12 = Batch identifier (ignore for expiration).
  • Expiration: Add 5 years (e.g., May 2028).

Format 2: MMYY + Batch

  • Example: 1124CX3
  • Breakdown:
    • 11 = November
    • 24 = Year 2024
    • CX3 = Batch code.
  • Expiration: Add 3-5 years (check "EXP" date if unsure).

Format 3: Julian Date Code (YYYYDDD)

  • Example: 2023125
  • Breakdown:
    • 2023 = Year
    • 125 = 125th day of the year (May 5, 2023).
  • Expiration: Add 5 years (May 5, 2028).

Lot Number vs. Expiration Date

Feature Lot Number Expiration Date ("EXP")
Purpose Tracks production batch for quality control. Indicates safe-use deadline.
Format 6-8 alphanumeric characters (e.g., 2208F4). Month/Year (e.g., 06/2027).
Location Near barcode or edge of packaging. Printed separately, often on the box front/back.
How to Use Decode for approximate manufacture date. Do not use if expired.

What If There's No Expiration Date?

  1. Decode the lot number to estimate manufacture date (see formats above).
  2. Add 3-5 years for expiration (conservative guess).
  3. Inspect the condom:
    • Sticky, brittle, or discolored? Discard.
    • Unusual odor? Do not use.
  4. When in doubt: Replace it. Expired condoms have higher failure rates.

Why Lot Numbers Matter

  • Safety: Confirms the condom hasn't degraded past its shelf life.
  • Recalls: Manufacturers use batch codes to identify affected products.
  • Storage checks: Verifies if condoms were stored properly (heat/humidity shorten lifespan).

Pro Tips

  • Store condoms in a cool, dry place (not wallets or glove compartments).
  • Write the expiration date on the box in bold marker if it's hard to read.
  • Check for CE/ISO marks-ensure the product meets safety standards.
