Updated on Mar 25, 2025

Trezor wallet recovery cannot happen without the complete recovery phrase, also known as the seed phrase. But what to do if you’ve lost your Trezor seed or found out that your backup phrase is invalid or incomplete?

Users often reach out to us for help recovering their Trezor seed phrase. We’ll explore the reasons why messages like “Seed phrase does not match any known wallet” or “Invalid recovery seed” may appear on your Trezor screen and how to fix them.

What Is the Trezor Recovery Seed, Where to Find It & How to Retrieve the Seed Phrase?

Trezor recovery seed is a 12-, 18-, or 24-word phrase that is  generated when you first set up your Trezor device and follows the BIP39 standard. Losing it means you lose your money forever, so keep it safe.

The words in a BIP39 seed phrase are selected from a fixed list of 2048 English words, which makes them easy to read, recognize, and write down correctly. Although the list avoids similar-looking words and complex spellings, there are many people who have troubles rememberung their seed phrases. 

Trezor Seed Phrase and Recovery Options

Lost your Trezor wallet? Your seed phrase can restore access on any Trezor device.

Where to Find Trezor Seed Phrase Storage

Trezor does not keep your seed phrase on the device or in any software for security reasons. Instead, “Trezor hardware wallet ships with a pair of wallet backup cards that you should use for writing down the words when you backup your device“. If you’re searching for your recovery phrase, start by checking these backup cards.

Think carefully about other places where you might have stored your recovery phrase.

Physical Locations to Check:

  • Notebooks, sticky notes, or personal journals
  • Papers inside a safe or a lockbox
  • Hidden locations like drawers, inside books, or under furniture
  • Even unexpected places—some users write it on the back of a business card or inside a wallet

Digital Backups (Not Recommended to Keep Phrase There, But Worth Checking):

  • Password managers – apps like Bitwarden or 1Password
  • Encrypted USB drives
  • Cloud storage (risky, but some users save it there)

If you still can’t find your seed phrase or its incomplete you can turn to seed recovery services or explore possible reasons for errors and how to troubleshoot them.

Best Ways to Backup Trezor Recovery Seed

Don’t store your seed phrase online!

One of the best seed phrase storages is Trezor’s metal backup. It’s durable and safe from corrosion. The Trezor Keep Metal 12-word recovery seed backup is a solid option compared to paper.

For extra security, we recommend to use Trezor Shamir Backup to split your seed. The SLIP39 protocol aka Shamir Wallet Backup is a more secure way to back up and recover your wallet. Instead of a single 12-, 18-, or 24-word seed phrase like the standard BIP39 method, SLIP39 splits your seed into multiple “shares”. You can still recover your wallet with the remaining shares, even if you lose one. The trezor model t and trezor safe 3 use SLIP39 protocol. But the trezor model one only uses BIP39.

When Trezor Seed Recovery is Impossible

If the seed phrase is fully lost there is no way to access the wallet. Even crypto recovery services can not help you to get it back.

In all other scenarios, like a partial mnemonic phrase, corrupted data etc., there is still hope for recovery. If you’ve tried to recover Trezor seed yourself and hit a dead end, reach out to Crypto Recovers for fast and reliable solutions!
