The serial number on your Zenni glasses holds all of the important information about the glasses themselves, but it can be hard to find. 

Zenni glasses have the serial number printed on the inside of one arm. This number is 6 or more numbers long. If it has worn off or is unreadable there, you will not be able to find it anywhere else.

Can You Find the Serial Number for Zenni Glasses Online

Unfortunately, you cannot find the serial number for your Zenni glasses anywhere except on the glasses themselves. That means that you cannot find it online before or after you place your order.

The serial number represents when and where the glasses were made, so technically, there can be no serial number until the manufacturer has completed making them. 

If you wear your glasses every day or you’ve had the glasses for years, and the serial number is rubbed off from the arm, unfortunately, there is no way to find the original serial number.

In fact, even if you call the Zenni customer service number, they still won’t be able to tell you the serial number that was on your glasses. 

What Can I Do?

Be proactive! If you think you’ll need to quickly find the serial number for your glasses in the future, you should do one of the following:

  • Write it down and keep it somewhere safe.
  • Take a photo of the serial number. 

Then, you will always have it handy, even if it wears off over time. 

What Does the Serial Number Mean on Zenni Glasses?

By definition, a serial number is an identifier unique to the item that describes something about it. 

When it comes to Zenni glasses, the serial number is distinctive to the exact pair of glasses you ordered and received. Therefore, there is no other pair of glasses with the exact same serial number as yours. 

On the arm of your Zenni glasses, you will see a variety of numbers. The first numbers represent the manufacturer’s style numbers and color codes. Whereas the second set of numbers are measurements of your glasses in millimeters. 

All of these numbers together make up the serial number for your Zenni glasses. 

You should also know that the first number in the second set is the lens width, the second is the bridge length, and the third is the temple length. (Although sometimes, the temple length is listed first.)

What Can You Use the Serial Number on Zenni Glasses For?

Finally, you are likely wondering what you can use the serial number for on Zenni glasses and why it’s important to know where to find it. 

You cannot use the serial number on your Zenni glasses in order to reorder another pair. And this is simply because the serial number is unique to that individual pair of glasses and cannot be repeated. 

However, that does not mean that the serial number is useless! The best thing about the serial number on Zenni glasses is that it shows the measurements of your glasses. 

Therefore, if you love the size and fit of your glasses, you can use those numbers to purchase another pair that has the same measurements. Or if they don’t fit quite right, you can ensure you adjust the measurements accordingly and get the pair that fits your face perfectly! 

Is the Zenni Serial Number the Same as the Tracking Number?

Many Zenni customers want to know whether or not the serial number is the same as the tracking number. So if you’re confused, don’t worry; you’re not alone. 

However, you should know that the serial number is not the same as the tracking number. Once you’ve ordered your Zenni glasses, you will receive a tracking number with your confirmation email. 

This number can only be used to ensure your glasses are on the way, it does not tell you anything about your Zenni glasses, nor can it be used to re-order a new pair if you need one. 

Like the serial number, the tracking number is unique to the pair you ordered and cannot be used for anything else.
