OP, it isn’t mico – it’s micro. This may be why you’ve had trouble finding the Help pages.

Quoting from Registering as a seller Help page:

❝Here's how to verify your account using microdeposits:

1. Sign in to Seller Hub or My eBay.
2. Select the banner to verify your bank account.
3. Select Verify with microdeposits.
4. Once they've reached your account (1-3 business days), sign in to Seller Hub or My eBay.
5. Select the banner to verify your bank account and enter the microdeposit amounts.

It can take up to 3 business days for microdeposits to reach your account, and we'll email you to confirm they've arrived. The microdeposits will be withdrawn from your bank account within a few days.

Tip
Don't attempt to enter any amounts until the microdeposits have reached your bank account, as this could cause issues with verifying your account.❞
