With zone filtering on, StoreConnect asks a shipping provider for rates only when the customer's delivery address falls inside the provider's **Zone**. Each region then quotes from the right account. Without zone filtering, StoreConnect asks every active provider for rates on every address. You rely on each carrier's own API to refuse the routes it cannot serve. ## Before you start :::warning Every **Shipping Provider** already has a **Zone**, because the field is required. Turning on zone filtering applies all of those zones at once. A provider whose zone is narrower than the area it really serves stops being asked for rates, and those rates disappear from checkout with no error. ::: - Audit the **Zone** on every active provider (`s_c__Zone_Id__c` on `s_c__Shipping_Provider__c`). Compare each zone with the area the account really serves. See [set up shipping providers](setting-up-shipping-providers). - Create or correct a zone for each region. See [configure zones for tax and shipping areas](zones). - Set the **Strict** field (`s_c__Match__c`) to `strict` on every zone used for a regional split, as described in [Set your zones to Strict](#set-your-zones-to-strict). There is no way to exempt a provider from the filter. Once zone filtering is on, every provider is limited to the provider's zone. ## Set your zones to Strict A zone used for a regional split must have the **Strict** field set to `strict`. The field defaults to `loose`. A loose zone matches an address on any one of the zone's criteria. For example, a loose zone built from "United States plus California" matches every address in the United States, because every one of them matches the country. A regional split built on loose zones does not split anything. A strict zone matches only when all of the address details match. A loose zone does not raise an error. The only sign is that a provider returns rates for addresses outside the provider's region. ## Turn on zone filtering 1. Open the **Store** record. 2. Go to the **Store Variables** list (`s_c__Store_Variable__c`). 3. Create a store variable with **Key** set to `shipping.provider_zone_filtering_enabled` and **Value** set to `true`. 4. Save the record. To turn zone filtering off, set the **Value** to `false` or delete the store variable. While the variable is absent or `false`, StoreConnect asks every active provider for rates. ## How a provider is chosen StoreConnect works out which zones the delivery address belongs to, then asks the providers in those zones: | Situation | Which providers are asked | |---|---| | The address matches one or more zones | Providers in those zones | | The address matches no zone | No providers, so the customer sees no provider rates | | StoreConnect cannot work out a zone for the address, such as a cart with no country yet | Every provider, with no filter | ## Do not overlap zones within one carrier code One address can match several zones at once. For example, a city address also matches the zone for the state and the zone for the country. Zones have no order of precedence, so the zones you use for one carrier must not overlap each other. If two providers with the same carrier code both match an address, their rates collide and StoreConnect drops one of them arbitrarily. The collision is reported to StoreConnect's error monitoring, not to you, so test each region after you set up the zones. Overlap between different carriers is fine. StoreConnect separates providers by carrier before it checks zones. Each provider points at a single zone. To cover several regions with one account, build one zone that spans all of them, the same way you would for shipping rates. ## Watch for addresses with an unrecognized state A zone scoped to a state matches an address only when StoreConnect recognizes the state in the address. For example, a customer who types `Calif.` instead of `CA` matches only zones that have no state. A provider scoped to California is then not asked for rates, and the customer does not see that provider's rates. Shipping rates you define yourself are matched to zones the same way. ## What zone filtering does not affect - **Lodging a shipment and tracking it.** StoreConnect lodges and tracks a shipment after the customer chooses a rate, without checking zones, whatever the destination. See [shipment tracking](shipment-tracking). - **Shipping rates you define yourself.** Custom rates are already matched to zones, and zone filtering does not change them. See [set up shipping rates](setting-up-shipping-rates). ## Changes can take up to an hour to show StoreConnect caches the rates for a cart for up to an hour. Any change to the cart, such as a new address or different items, fetches fresh rates. A cart left untouched keeps showing the old rates after you turn on zone filtering or change a provider's zone, until the cache expires. Use a fresh cart when you test. ## Check it worked Build a cart on your storefront with a delivery address inside one region, and confirm that only that region's carrier account returns rates at checkout. Change the address to another region and confirm the rates switch to the other account. A cart with an address in neither region should return no provider rates at all. --- ## Follow StoreConnect - [Email Newsletter](https://storeconnect.com/c/lp-newsletter) - [LinkedIn Newsletter](https://www.linkedin.com/build-relation/newsletter-follow?entityUrn=7444956928444862464) - [YouTube](https://www.youtube.com/channel/UCngKdP2x8l1wcbAKW3tvU8g) - [LinkedIn](https://www.linkedin.com/company/storeconnect) - [X / Twitter](https://x.com/storeconnecthq) ## Popular Links - [Partners](https://storeconnect.com/partners) - [Become a Partner](https://storeconnect.com/become-a-partner) - [News](https://storeconnect.com/articles/news) - [Events](https://storeconnect.com/articles/events) - [Feature Comparison](https://storeconnect.com/how-we-compare) - [Download a free trial](https://appexchange.salesforce.com/appxListingDetail?listingId=a0N3A00000FMkeKUAT) - [Book a Demo](https://storeconnect.com/contact) ## Documentation - [Help documentation](https://support.storeconnect.com/help-documentation) - [AI agents](https://support.storeconnect.com/ai) - [Videos & tutorials](https://support.storeconnect.com/videos-tutorials) - [Developer reference](https://support.storeconnect.com/developer-reference) - [Release notes](https://support.storeconnect.com/release-notes) - [Troubleshooting](https://support.storeconnect.com/troubleshooting) - [Trust Center](https://trust.getstoreconnect.com/) - [Status Page](https://status.storeconnect.com/) ## Contact - info@getstoreconnect.com - US +1 415 745 3230 - AUS +61 2 8365 2308 100 S Ashley Dr, Suite 600-2461 Tampa FL 33602-600 USA Level 22, Sydney Place 180 George Street Sydney, NSW, 2000, AUS ## Machine-readable - [Site index for agents](https://storeconnect.com/llms.txt): curated map of the StoreConnect site in llms.txt format - [Documentation index for agents](https://support.storeconnect.com/llms.txt): full technical and product documentation map Every page and article on this site has a Markdown rendering: append `.md` to its URL.
