So you typed in your code at amazon.com/mytv and got hit with that dreaded "invalid code" message. Annoying, right? You check the code again, type it in — same error. You start wondering if your TV is broken, or if Amazon just hates you today.
Relax. This is actually one of the easiest MyTV errors to fix once you understand why it happens. And no, your TV isn't broken.
Here's the truth: "invalid code" almost always means one of three things — you typed it wrong, it expired, or it was already used. That's it. Let's walk through each one so you can get past this in the next two minutes.
What "Invalid Code" Actually Means
Amazon isn't being vague on purpose — the error just doesn't tell you which of the three problems you're dealing with. Here's what each one looks like:
- Typo — You misread a character. The letter O vs. the number 0, or the letter I vs. the number 1. Easy to do, especially if you're typing fast.
- Expired code — The code has a short lifespan (usually around 10 minutes). If you took too long, it's dead.
- Already used — You (or someone else on your account) already activated a device with that code. Each code only works once.
Once you know which one applies, the fix is straightforward.
The Real Fixes, In Order
I know this sounds like basic advice, but you'd be shocked how often this is the whole problem. MyTV codes use a mix of letters and numbers, and some characters look almost identical on a TV screen.
Watch out for these tricky pairs:
- O (letter) vs. 0 (zero)
- I (letter) vs. 1 (one)
- B (letter) vs. 8 (eight)
- S (letter) vs. 5 (five)
Read the code out loud once, character by character, while you type it. Slow down. It's faster than re-entering the whole thing three times.
If you're sure you typed it correctly, the code has probably expired. This happens more often than you'd think — especially if you had to walk to another room to grab your phone or laptop.
Here's what to do:
- Close the Prime Video app on your TV completely (fully exit, not just back out)
- Reopen the app
- A fresh code will appear
- Type it in immediately — don't delay
Fresh codes are the single biggest fix for the "invalid code" error. Try this before anything else.
Each MyTV code is single-use. Once it's been used to activate a device, it's dead forever. If you're trying to activate a second TV with a code you already used on your first TV, that's why you're getting the invalid error.
The fix: get a fresh code from the second TV. Don't reuse anything.
Also worth checking — if you share your Amazon account with family, someone else might have already used the code you're staring at. Ask before you assume it's broken.
⚠️ Important: Never Share Your Code Publicly
Your MyTV code links a device to your Amazon account. If you post it on a forum, social media, or give it to someone claiming to be "Amazon support," they can activate their own device on your account. Only enter codes on amazon.com/mytv directly — nowhere else.
Sometimes the problem isn't the code at all — it's the browser you're using. Ad blockers, privacy extensions, or an outdated browser can interfere with the activation page and cause it to reject valid codes.
Here's what to try:
- Switch to a different browser (Chrome, Edge, Firefox, Safari)
- Open a private/incognito window and try again
- Try a different device entirely — phone instead of laptop, or vice versa
- Disable ad blockers temporarily
You'd be surprised how often this works when everything else fails.
Pro Tip: Screenshot the Code
Take a photo of the code on your TV screen before you walk away. That way you don't have to run back and forth, and you're less likely to mistype a character. It also lets you zoom in if a character is hard to read.
What If Nothing Works?
If you've tried fresh codes, different browsers, and double-checked every character — and it's still saying invalid — there's one more thing to check: your device's software.
An outdated Prime Video app or outdated TV firmware can cause the activation system to misbehave. Go into your TV's settings and check for software updates. Same thing for the Prime Video app itself — uninstall and reinstall it if updates don't help.
And if that still doesn't work, it's worth checking whether your TV model is still supported by Amazon. Older smart TVs get dropped from support occasionally, and that can cause activation to fail silently.
Frequently Asked Questions
How long does an Amazon MyTV code last?
Usually about 10 minutes, though it varies by device. Treat it like a one-time password — use it immediately after it appears, or request a fresh one.
Can I use the same code on my phone and my TV?
No. Each code is tied to one device and one activation session. You'll need a separate code for every device you want to link.
Why does it say invalid when I just typed the code correctly?
Most likely the code expired while you were typing. Request a fresh code and enter it right away. If that fails, try a different browser or clear your browser cache.
Does Amazon customer support fix invalid code errors?
Support can help if your account has a genuine issue, but 99% of "invalid code" cases are solved by requesting a fresh code and typing it correctly. Try the steps above before contacting support.

The Short Version
"Invalid code" on Amazon MyTV almost always means one of three things: a typo, an expired code, or a reused code. Request a fresh one from your TV, type it carefully, and enter it at amazon.com/mytv within a minute or two. That fixes it for the vast majority of people.
If it still fails, switch browsers, clear your cache, or check for TV software updates. And never share your code with anyone — treat it like a password.
