If you are using zip code based redirection feature, you can set an option so that customer doesn't need to enter their zip code again and again. We use cookies to determine if customer was redirected in the past based on a zip code. When cookie expires, customer would need to validate their zip code again.

To enable this feature, please follow these instructions.

1. Go to App > Global Settings > Scroll to "Zip code based redirection".

2. Enable "Automatically redirect if customer has already done zip code validation before" and hit save.

Additionally you can also pass "?isZipcodeValidated=true" query param which would not show a validator on redirected store. You can learn more about that feature by clicking here.
