How to Shorten an Amazon Link (5 Methods That Actually Work)

Learn how to shorten an Amazon link in seconds - manual trimming, amzn.to, and branded short links. Keep your affiliate tag intact and stay compliant.

Team U2L • 14 min read

You want to shorten an Amazon link because the raw URL is a 300-character monster stuffed with the product name, a session ID, a search query, a referrer tag, and a handful of parameters nobody can decode. Paste one into a text message and it wraps four lines. Drop it into a Twitter reply and there's no room left for words.

The link you actually want is clean, fits in one line, keeps your affiliate tag intact, and doesn't get you booted from the Associates program. That's a specific problem with specific answers. Below are five different ways to shorten an Amazon link, when each one makes sense, and the compliance rules you actually need to worry about.

The fastest way to shorten an Amazon link is to keep only the /dp/ASIN portion of the URL and drop everything else. For affiliates, add ?tag=your-associate-id at the end. For branded, trackable links use a URL shortener like U2L AI at u2l.ai - no login required.

Why Amazon URLs Are So Long

Amazon URLs are long because Amazon packs the product's title, its ASIN, the referring page, a session identifier, and a stack of tracking parameters into every product link. Copying the URL from a browser tab captures all of that noise, most of which the browser doesn't need to find the product.

Here's a real example from a random kettle listing:

https://www.amazon.com/Cuisinart-CPK-17-PerfecTemp-Cordless-Electric/dp/B003BR5LTK/ref=sr_1_5?crid=2X0F1A8&keywords=electric+kettle&qid=1728492834&sprefix=electric+ket%2Caps%2C158&sr=8-5

That's 189 characters. Only two chunks actually matter to Amazon's servers:

  • /dp/ - the path that tells Amazon "this is a product detail page"
  • B003BR5LTK - the ASIN (Amazon Standard Identification Number), a 10-character code that uniquely identifies the product

Everything else is decoration. The product slug in the path (Cuisinart-CPK-17-PerfecTemp-Cordless-Electric) is there for SEO and readability. The ref=, crid=, keywords=, qid=, sprefix=, and sr= parameters tell Amazon how you got to the page. None of them are required to open the product.

Which means you can hack most of it off yourself. That's Method 1.

Method 1: Trim the URL Manually

The manual method costs nothing, uses no third-party tool, and works on any Amazon domain (amazon.com, amazon.co.uk, amazon.in, all of them). It's the trick every seasoned Amazon shopper eventually learns.

Step 1: Find the ASIN

Copy the full URL from your browser's address bar. Scan for /dp/ followed by 10 characters (a mix of letters and numbers). That 10-character block is the ASIN. In our kettle example it's B003BR5LTK.

If you can't spot /dp/, look for /gp/product/ instead - some older or ad-driven Amazon URLs use that path. The ASIN follows the same rule: 10 characters immediately after.

Step 2: Rebuild the URL

Drop everything except the domain, the /dp/ (or /gp/product/) path, and the ASIN. You end up with:

https://www.amazon.com/dp/B003BR5LTK

That's 37 characters. Same product, five times shorter, still works everywhere. Test it - it opens the exact same page as the 189-character original.

Step 3: Add your affiliate tag (if you're an Associate)

If you're promoting the link as an Amazon Associate, tack on your tracking ID as a query parameter:

https://www.amazon.com/dp/B003BR5LTK?tag=yourid-20

Replace yourid-20 with your actual Associates tracking ID. This preserves attribution so you get credit for the sale. Without the tag= parameter, Amazon has no way to know the click came from you.

Manual trimming is the go-to for personal messages, quick DMs, and anywhere you don't need tracking. It's also the base layer for the next three methods - once your URL is trimmed, it shortens even further when you run it through a shortener.

Method 2: Use Amazon's Built-In Shortener

Amazon offers two official short-URL formats: amzn.to for consumer sharing and a.co for Associates. Both are provided by Amazon and are the safest option for anyone worried about compliance, because Amazon obviously can't ban links it hosts itself.

For casual sharing (amzn.to): open the product page in the Amazon mobile app, tap the Share icon, and pick "Copy link." You get back something like https://amzn.to/3xYzABC. That's the consumer-grade share link. No tracking tag, so it's useless for Associates but perfect for sending a link to a friend.

For affiliates (a.co): log into your Amazon Associates dashboard and enable SiteStripe. A bar appears at the top of every Amazon page. Click the "Text" option, then the "Short Link" toggle. You get an a.co short link with your Associates tag already baked in.

The catch: both amzn.to and a.co are opaque short links. Your reader can't tell at a glance where the link goes. That's fine on Amazon's own tools (they're clearly Amazon-branded), but it removes any signal from your side. You also get no analytics, no ability to change the destination later, and no branding.

If that's all you need, though, Amazon's tools are free and always compliant. Start there.

Method 3: Shorten With a URL Shortener

A dedicated URL shortener gives you three things Amazon's tools don't: click analytics, editable destinations, and a memorable slug. For anyone who does this more than once a month, that's worth the 20 seconds it takes.

Here's how it works with U2L AI's URL shortener:

  1. Trim your Amazon URL down to /dp/ASIN first (see Method 1). Add your ?tag=yourid-20 if you're an affiliate.
  2. Go to u2l.ai or the Amazon link shortener tool - no login required.
  3. Paste your trimmed URL into the box.
  4. Optionally set a custom alias like u2l.ai/kettle instead of a random string.
  5. Hit shorten. Copy the result. Ship it.

You now have u2l.ai/kettle (or similar), which is 12 characters, memorable, and gives you a full analytics dashboard the moment you create a free account. You can see where clicks came from, what devices they used, and how many turned into scrolls.

If you're the type who tracks everything - which honestly, if you're shortening Amazon links for revenue, you should be - a shortener beats amzn.to on every axis except pure brand safety. The full walkthrough for creating a custom short URL covers the alias-picking part in more detail.

Getting your own domain (yourbrand.co or similar) and pointing it at a shortener takes the professionalism up a level. Instead of u2l.ai/kettle, you serve yourbrand.co/kettle.

Why bother? Branded links reportedly get around a 34% higher click-through rate than generic short links, according to third-party industry research. That's a real effect. People trust techreview.co/deal more than bit.ly/3xYzABC because they can see the destination is somewhere they recognize.

To set this up:

  1. Buy a short domain (something like .co, .link, or .io works well for this).
  2. Point its DNS to your URL shortener. With U2L AI, custom domains auto-provision SSL, so setup takes a few minutes and no manual certificate work.
  3. Route your Amazon affiliate links through that branded domain going forward.

We've written more about why branded short links convert better in our guide to branded links. The short version: a branded URL feels like a recommendation from a person, not a spam bot. Amazon's own amzn.to doesn't give you that.

Method 5: Generate a QR Code

Sometimes a link isn't the right format. If you're recommending Amazon products in a YouTube video, on a print flyer, or on packaging, a QR code beats a spelled-out URL every time. Nobody types amazon.com/dp/B003BR5LTK?tag=yourid-20 from memory.

Every shortened link on U2L AI comes with a matching QR code automatically. You don't need a separate tool. Create the short link, click the QR tab, download the image (SVG for print, PNG for screens). Anyone scans it with a phone camera and they're on the Amazon product page in a second.

The dynamic-link angle matters here too. If you print a QR code for a specific product, and Amazon later runs out of stock or you switch to a different affiliate program, you'd normally reprint everything. With a dynamic short link behind the QR, you swap the destination in the dashboard and the same printed code now points to the new page. That's how dynamic QR codes stay useful for years instead of aging into wallpaper.

Affiliate Compliance

Here's where a lot of new affiliates get anxious, and honestly, the rules are less scary than they look. The Amazon Associates Operating Agreement doesn't ban URL shorteners. What it bans is cloaking - hiding the fact that a link goes to Amazon at all.

The concrete rules, in plain English:

  • You can shorten Amazon links. Manual trimming, amzn.to, a.co, third-party shorteners - all allowed.
  • You cannot obscure the destination. If someone can't reasonably tell your link goes to Amazon, you're violating the agreement.
  • You must disclose affiliate relationships. This is an FTC endorsement requirement, not just an Amazon one. A visible line like "As an Amazon Associate I earn from qualifying purchases" near your links is standard practice.
  • Don't strip out the tag. Some shorteners try to be helpful and remove query parameters. That kills your attribution. Test any new shortener by clicking your own link and confirming the Amazon URL that loads still contains your tag=.

That last point trips people up. If you're using a shortener you're unsure about, generate a short link, click it, and inspect what actually appears in the browser bar after you land on Amazon. If the ?tag=yourid-20 is missing, either the shortener is dropping it or Amazon is scrubbing it because you did something wrong upstream. Either way, no attribution, no commission.

And if you're troubleshooting why Amazon links land in a browser instead of the app, that one has its own step-by-step fix.

Common Pitfalls

Five mistakes we see over and over:

Forgetting the tag. You trim the URL beautifully, share it, get a thousand clicks, and earn zero commission because ?tag= never made it into the short link. Always test-click your own short URL before it goes live.

Using a country-mismatched domain. An amazon.com link shown to a UK reader sends them through the US store, where they may or may not have an account, and where prices differ. If your audience is international, either link to amazon.co.uk for UK readers or use a link that geo-routes to the right storefront.

Cloaking with vanilla redirects. A short link that lands on yourbrand.co/product and then bounces to Amazon is fine. A short link that loads Amazon inside an iframe on yourbrand.co is not fine - that's classic cloaking and it violates both Amazon's agreement and browser security expectations. Don't do it.

Not tracking clicks. If you don't measure which links get clicked, you're guessing which products, placements, and posts drive revenue. Tracking link clicks is table stakes for affiliates who want to grow beyond hobby income.

Reusing static links across campaigns. If you share the same short link on Twitter, in your newsletter, and on TikTok, you can't tell which channel converted. Create one link per channel (or add UTM parameters to each). This is where a shortener with folders and tags saves your sanity.

Frequently Asked Questions

The shortest self-hosted format is https://www.amazon.com/dp/ASIN, which uses only 27 characters plus the 10-character ASIN. Amazon's own amzn.to or a.co links come in around 20-23 characters total. Third-party shorteners like U2L AI can produce even shorter branded links, especially with a short custom alias.

Yes. Amazon's Operating Agreement allows shortened affiliate links as long as it's clear to the reader that the link goes to Amazon and your tracking tag survives the redirect. Cloaking that hides the Amazon destination is what's banned, not shortening itself. Add an FTC-compliant affiliate disclosure near the link.

Yes, amzn.to is Amazon's official consumer share link and is generated automatically when you use the Share button in the Amazon app or website. Amazon Associates get the parallel a.co format through SiteStripe. Both are hosted and maintained by Amazon.

Only if the shortener strips the ?tag= query parameter during the redirect. Reputable shorteners preserve every query parameter by default. Always test a new short link by clicking through and confirming the final Amazon URL still contains your Associates tag before you share it widely.

What's the difference between amzn.to and a.co?

amzn.to is the general consumer short link Amazon generates via the Share button - no tracking tag attached. a.co is the Associates version generated through SiteStripe, which bakes in your Associates tracking ID for commission attribution. If you're not an Associate, you'll only see amzn.to.

Yes, if you use a third-party shortener like U2L AI. Amazon's own tools generate random short codes with no customization. Custom aliases are memorable, brandable, and easier to say out loud on video or in a podcast. Just avoid using registered trademarks or misleading terms.

They do, and often better than the raw Amazon URL because they fit within character limits and look cleaner. For platforms that only allow one link, pair a short link with a link-in-bio page listing multiple products. Track which product gets the most clicks and double down on that content.

Yes. U2L AI lets you shorten Amazon URLs without creating an account. You get a working short link instantly. Signing up unlocks click analytics, editing, and custom aliases, but the shortening itself is free and requires no login. The Amazon link shortener tool is built specifically for this workflow.

Wishlists live at amazon.com/hz/wishlist/ls/XXXXXX. That URL is already reasonably short but not memorable. Run it through a shortener and give it a memorable alias like u2l.ai/birthday-wishlist. The shortened link redirects to your wishlist normally.

Wrap-Up

Shortening an Amazon link isn't one problem - it's a spectrum from "make this fit in a text message" to "run a global affiliate operation with per-channel attribution." Manual trimming handles the first case in under 30 seconds. A branded short link with click analytics handles the last one.

For most people, the sweet spot is method 3: trim the URL manually to preserve your tag, then run it through a shortener like U2L AI for a clean, trackable link that you can update later without reprinting anything. It's free, no login required, and takes about a minute end-to-end.
