How to Find Your Sunglasses Model Number

Ordering replacement lenses starts with one thing: knowing exactly which model you own. The good news — every quality pair of sunglasses has its model number printed right on it. Here's how to find it in under a minute.

The model number lives on the inside of the temple arm, usually next to the size.

1. Look at the inside of the temple arm

Take your sunglasses off and look at the inner side of the temple arm — the arm that rests over your ear. Most brands print or engrave the model information there. You're looking for a short combination of letters and numbers, usually with a size code beside it.

2. What you're looking at, part by part

  • Model number — the important one. Starts with the brand's prefix (Oakley = OO, Ray-Ban = RB) followed by four digits, e.g. OO9102.
  • Model name — the friendly name, like Holbrook or Wayfarer.
  • Lens width — the number before the little square (like 55□18). It's the lens width in millimeters, and it matters (more below).
  • Bridge & temple — the two numbers after it are the bridge width and the temple length. Handy, but the model number is what you really need.

3. The codes, brand by brand

  • Oakley: starts with "OO" plus four digits — e.g. OO9102 (Holbrook). Some older models use "24-" or "12-" codes.
  • Ray-Ban: starts with "RB" plus four digits — e.g. RB4165 (Justin) or RB2140 (Original Wayfarer), with the lens size next to it like "54□16".
  • Costa: a two- or three-letter style code (like "WJ" for Waterjack) plus the lens size.
  • Maui Jim: usually "MJ" plus a number, or the style name printed with the size.

4. Can't read it anymore?

On well-loved frames the printing sometimes wears off. Try these:

  1. Check the original case, box or receipt — the model is usually printed there.
  2. Look on the nose bridge or the inside of the opposite temple arm.
  3. Still stuck? Send us a photo of your frames — we identify models every day and will match you to the right lenses, no purchase required.

Why the size code matters

Many models come in more than one lens size — for example, Holbrook (55mm) and Holbrook XL (59mm) are different frames and different lenses. Match the width you found on your arm to the right product, and your new lenses will snap in perfectly.
