Amazon Brand Catalog Lock: The Setting That Stops Others Editing Your Listing

In 2025 Amazon added a setting to Brand Registry that decides whether anybody outside your brand can rewrite your product title, replace your main image, or edit your bullets and description. It is called Brand Catalog Lock, it costs nothing on top of Brand Registry, and it is switched off until somebody turns it on. Most brand owners we speak to have never heard of it.

Reported by Dickinson Wright, August 2025, and Hovey Williams, September 2025, both third party, and they agree on what the feature is and what it covers.

We understand how it feels to open your own detail page and find somebody else's words on it. You wrote that title. You paid for that photograph. Then a reseller with an opinion about keywords pushed a version of it live, your conversion moved, and nobody sent you a notification about any of it.

The part that will genuinely annoy you is that Amazon has not made this easy to find. We looked for an Amazon help page under that name and could not locate one, and Amazon's own Brand Registry page lists Transparency, Project Zero, Report a Violation and the Counterfeit Crimes Unit without mentioning Brand Catalog Lock at all. So a genuinely useful protective setting is currently something you hear about from other sellers.

What the lock actually changes

An Amazon detail page is not your page. It is a shared record that several parties can submit data to, and Amazon decides which submission the shopper sees.

Amazon says this plainly in its own seller forums: if there are multiple sellers contributing information to a product detail page, you might find that some of your requested changes do not appear. Source: Amazon Seller Forums, moderator post, Amazon primary.

So the default state of a brand-registered ASIN is not what most owners assume. The default is that other parties may contribute and you may dispute afterwards. Brand Registry raises how much weight your submissions carry, and it does not make you the only voice in the room.

Two separate third-party accounts describe the same hierarchy, with Amazon's own retail and vendor systems above brand owners, brand owners above ordinary sellers, and an algorithm choosing between them, as reported by Riverbend Consulting, 2024, and Goat Consulting.

Brand Catalog Lock changes the default. With it on, the four fields a shopper actually reads before deciding, so the title, the main image, the bullets and the description, are restricted to authorised brand representatives, and a contribution from anyone else does not take effect.

Reported by Velocity Sellers and SupplyKick, both 2026, which agree that the feature is off by default and is applied by the brand owner rather than granted automatically.

Where it lives, and why we are not giving you a click path

Everything published about this setting places it inside Brand Registry, in the area where brand benefits are managed, applied to ASINs you select rather than switched on across the whole catalogue in one action. That is what the two sources above describe, and it matches what brands have reported to us.

What we are not going to do is print an exact sequence of clicks as though it were documented, because Amazon has not documented it publicly under that name and the Brand Registry interface changes without announcement. A confident click path that turns out to be wrong wastes an afternoon and leaves a stressed seller assuming the feature is not on their account.

So the honest version is that it sits in the brand benefits area of Brand Registry, and if it is not visible there, that absence is worth a support case of its own.

What Brand Catalog Lock does not protect

This is the section that matters most, because a protective setting people misunderstand is more dangerous than no setting at all. A brand that believes it is fully covered stops watching the page. The lock governs who may contribute to four content fields, and everything else on and around your ASIN is unchanged.

The field scope in that table follows Velocity Sellers and SupplyKick, 2026, which agree that the lock covers content fields and leaves pricing, inventory and seller-specific fields alone.

The last row is reasoning rather than a citation, and it is straightforward reasoning: the lock decides which outside parties may contribute, so it has nothing at all to say to Amazon's own compliance and catalogue systems. If Amazon decides your image breaks a category rule, a lock you applied does not enter into that decision.

The second row is the one that surprises people. Locking your content does not remove a single seller from your offer list, because content contribution is a catalogue question and who may sell is a rights question, answered through separate routes. A brand can have perfectly locked content and still be losing the Buy Box every afternoon.

How to tell whether this is your problem

Six checks, and they cost about twenty minutes across a normal catalogue.

1. Read your own title out loud. Unauthorised edits rarely look dramatic. They read like your title with a phrase moved, a size dropped or a keyword bolted onto the end, and they are hard to spot because nobody rereads a title they wrote two years ago.
2. Compare the main image against the file you supplied. A different crop, or a lifestyle shot promoted into first position, is the most common quiet change and the one that moves click-through fastest.
3. Look at the brand field on the ASIN. If it shows anything other than your registered brand, that is a catalogue-level change rather than a cosmetic one, and it tends to break other things downstream.
4. Check whether your edits are surviving. Making a small correction and finding the old text back a few days later is the clearest signal that you are not holding the winning contribution on that ASIN.
5. Watch unit session percentage rather than sessions. When traffic holds and conversion falls, the page changed rather than the demand, and this usually shows up before anyone notices the wording.
6. Open the other sellers list. New names appearing at the same time as content changes suggests the two are connected, and that is a different problem with a different fix.

Points four and six separate the two situations most cleanly, and the rest of this post depends on that distinction, because the lock addresses one of them and does nothing for the other.

What to check before you switch it on

There is a strong urge to turn a protective setting on the moment you learn it exists, and it is worth resisting for a few days, because the lock preserves the page as it stands on the day it is applied. Locking a page that is already wrong just makes the wrong version harder to dislodge.

1. The content gets fixed first. Title, main image, bullets and description all reviewed and corrected before anything is frozen, because whatever is live on the day is what the lock defends.
2. Whoever will need to edit later gets added first. Agencies, freelancers and internal staff all edit through Brand Registry permissions, and a lock applied before the list is complete produces a page nobody on your team can update.
3. The current values get recorded. A dated screenshot of each hero ASIN, or a Category Listing Report pulled and saved, turns a later argument from "it looks different" into "this field said this on this date".
4. Brand Registry roles get reviewed. Old agency accounts with editing rights are common on brands that have changed providers, and they carry straight through a lock because those users are, as far as Amazon is concerned, authorised.
5. The ASIN list gets decided deliberately. Hero ASINs and anything with a history of unexplained changes are the obvious starting point, and beginning narrow costs nothing.

Step two is the one that creates support tickets, because a brand can lock a catalogue, change agency six months later, and then spend a fortnight working out why the new team cannot push a title change. It is recoverable, and it is also avoidable with ten minutes of list-checking at the start.

What applying the lock looks like in practice

The sequence below is how our team works through it. The navigation wording is deliberately soft, for the reason given earlier.

1. The content is finalised and signed off. This is the real work and the step people skip. The title has to be the one you actually want, carrying the use case, the material and the quantity rather than a keyword list.
2. The authorised editor list is confirmed inside Brand Registry. Everyone who will legitimately need to edit, checked by name, before anything is restricted.
3. The ASINs are selected in the brand benefits area of Brand Registry. Selection is per ASIN according to both published sources, so a phased approach across hero products first is workable.
4. The lock is applied and then verified from the shopper side. Opening the live detail page in a logged-out browser after 24 to 72 hours is the only check that means anything, because the seller-side view shows what you submitted rather than what shoppers are served.
5. A record is kept of what was locked and when. Dates matter later. If a field changes on a locked ASIN, the date the lock was applied is the first thing any useful support case will reference.
6. Monitoring continues anyway. The table above lists everything the lock leaves exposed, so the weekly check does not stop because a setting was switched on.

We will not promise that a locked field can never change, because anyone telling you a setting makes a page permanently untouchable is selling certainty Amazon has not offered. What we can say from our own work is that the brands who get hurt are the ones with no record of what the page said last month.

The part the lock cannot do anything about

A client came to us with hijackers on their listings. Not editors, sellers. Other parties were selling on the ASINs, taking the Buy Box, and the brand was losing control of its own product page in the way that actually costs money.

No setting inside Brand Registry solves that, because the problem is not content contribution. Our team built IP complaints on the specifics: model numbers, the Brand Registry details, and product differentiation documents that established what the genuine product is and how it differs.

Then we bought the hijacker's product ourselves, photographed it against the real thing, and submitted the side-by-side packaging comparison as evidence. Then we followed up, repeatedly, because the first response to a complaint is very often a template that does not engage with what was submitted. The unauthorised sellers were removed and the brand got Buy Box control back.

That case is the argument for the lock and the limit of it in the same story. If those sellers had also been editing the content, the lock would have closed that door permanently. It would not have removed one of them from the offer list.

Content protection and seller removal are separate pieces of work, and a brand that only does the first one has tidied the page while somebody else keeps the sale.

If sellers are the problem rather than edits, that is IP complaints and counterfeit enforcement work, and if the whole Brand Registry setup needs sorting out before any of it is usable, that is what our Brand Registry page covers.

Keeping the lock from becoming a false sense of safety

The failure mode with any protective setting is that it gets switched on once and then treated as finished, and Amazon changes what settings do often enough that this is a poor assumption.

1. A monthly record of the four locked fields per hero ASIN. Five minutes of copy and paste that turns "something feels off" into a dated comparison, which is the only kind of evidence a catalogue case responds to.
2. A quarterly review of the authorised editor list. Former agencies, former staff and old freelance logins all persist, and every one of them edits straight through a lock.
3. Backend fields watched separately. Keywords, attributes, variation theme and category node sit outside the lock entirely, and those are the fields that quietly decide whether you are indexed and whether the listing stays live.
4. The offer list checked on the same schedule. Seller changes and content changes arrive together often enough that noticing one should prompt a look at the other.
5. Notifications actually read. Amazon's warnings about catalogue and policy changes are unglamorous and easy to skim past, and they are the cheapest information you will ever be given about your own listings.

None of that is difficult. It is the kind of work that gets dropped in a busy quarter and then costs a fortnight to unpick.

What we would do first if this were our account

Record what the page says today, on the hero ASINs at least. It costs five minutes and it is the one thing that cannot be reconstructed after the fact, because Amazon does not hand sellers a clean version history of their own detail pages.

Then fix the content before locking anything, since the lock defends the version that is live when it is applied, and a frozen mediocre title is worse than an editable one.

Then look honestly at which problem you actually have. If your words keep being replaced, the lock is the right tool and it costs nothing. If unfamiliar sellers are taking your Buy Box, the lock will not touch that, and the work is evidence gathering, complaints built on specifics rather than adjectives, and follow-up that does not stop at the first template reply.

That is also why we will not promise a timeline. These cases move at Amazon's pace, and what helps is going back with the same evidence rather than rewriting the request.

What we can tell you before you spend anything is which of the two problems is on your account, whether your Brand Registry setup is doing the job you think it is doing, and which of your ASINs are exposed.

That is what the free, no-obligation audit covers, and if your catalogue turns out to be in good shape we will say so. If it is the catalogue structure underneath the content that is causing the trouble, our catalog troubleshooting page explains how we work through it.
