How the REVIVE verification code works

The direction of the check

Each outer box carries a printed code beginning RVL. Entering it on the verification page queries REVIVE production records and returns what those records say: the item, its strength, the batch number, and the production and expiry years.

The value is in the direction. Counterfeiting a label needs a printer. Producing a matching record needs access to the manufacturer's system.

Reading the result properly

A successful check returns the details held for that code, and those details should match the box in your hand. A code that resolves but describes a different product is a discrepancy worth raising, not a pass — that is the case people most often misread.

A code returning nothing is not automatically a counterfeit either. Codes are letters and numbers only, and a misread character is by far the most common cause. A code that repeatedly returns nothing means the box should be treated as unverified.

Why the same code appears on several boxes

A code identifies a batch, not an individual container, so every box filled from one batch carries the same code. Seeing a familiar code is expected and is not evidence of duplication. Customers ask about this often enough that it is worth stating plainly.

What it cannot tell you

Verification confirms a code matches a production record. It does not analyse the contents of the vial, and it cannot detect a genuine box that has been opened and refilled. It is one control alongside sealed packaging and batch documentation, not a substitute for them.
