I authenticated a bag with them. The process was very smooth and while it did take 2-3 hours, I’d rather they really inspect the bag thoroughly, rather than give me a rushed verdict… Have upgraded to a Certificate too which was great!Overall I’m very happy. I got 6 reasons for why my bag is authentic and that really helps… will come back for sure.

The Alyx authentication service is here for you to clarify the situation whether you have the real deal or the replica Alyx items. Our Alyx legit checking team wants you to know the verdict about your item, so if you want to know the verdict about your item, make sure to contact us.

Common questions about the Alyx authentication service

Can you authenticate my item? If yes, where do I start?

The short answer is: we most probably can.

On the off-chance that you place an order for an item we can't authenticate, we'll refund the purchase.

Besides, if we're not sure about an authentication's verdict, we would rather refund the purchase.

Our expertise is earned through the millions of words for the thousands of items we've covered in our Legit Check By Ch Library, where we keep publishing, updating, curating and tweaking the world's most exhaustive Library of fake vs real authentication guides.

To find out for sure whether we can authenticate an item or not:

1. Simply click the green button below
2. Find your item
3. You'll either find your item in our list, or, if you can't find it, you'll be able to select just the brand and the item type.
Let's go

What do I need to place an order?
Is it complicated?

Not much... just your device, information and... that's pretty much it! Even pics of your item are optional: you can upload them later at any given point.
How does the Alyx Authentication Service work? What is the process like?
How do I know I can trust you? Why do you claim to be the most trusted source of truth in the industry?
Who is this service for? Is the service for me?
What happens if my Alyx item is fake?

How long will the authentication service take?

The set timeframe for an answer on our authentication service is 48h. However, most of the time our answer will be with you faster than that. Sometimes we may take up to 48h simply because every authentication is a serious matter to us.

How many items can I authenticate if I purchase the service once?

One purchase is valid for the authentication of one item. If you need more than one item authenticated, rest assured — our team is happy to help you with as many items as you need. Simply use the "Add another item" box in the on the order page.
Let's authenticate

What payment methods have you got? What currencies?

We accept all credit/debit cards: Visa, Mastercard, Amex, Discovery etc. We can't accept PayPal, crypto, bank transfers or any other form of payment.

All our prices are in USD for the moment!

Is there a free alternative to the authentication service?

We understand the authentication service is not everyone's preferred option when it comes to authenticating an item. For this specific reason, we're building the Legit Check By Ch Library, the free alternative to our service. Over there, you will see the very documents we use to authenticate items for our customers. Visit the library to explore the detailed comparisons on how to spot fake and authentic items — all free.
