AddressPill vs Address Ninja
Address Ninja stops checkout when a rule matches. AddressPill can let checkout finish, then check whether the address exists and ask the customer to correct it. Those are different jobs, and the prices are different shapes. At a few thousand orders a month, Ninja’s flat fee is the cheaper bill. It still does not publish a check that the street exists.

What the monthly bill looks like
Ninja’s price does not move with volume. AddressPill’s verification price does. Under about 100 verified orders, Starter at $4.99 and $0.05 per order land in the same range. After that, Ninja stays cheaper if all you need is a block. The extra money on AddressPill is the existence check and the option not to stop checkout.
| Orders in a month | AddressPill verification | Address Ninja |
|---|---|---|
| 100 | $5 | $4.99 to $14.99 |
| 500 | $25 | $4.99 to $14.99 |
| 1,000 | $50 | $4.99 to $14.99 |
| 5,000 | $250 | $4.99 to $14.99 |
Where a block is the wrong tool
| Address | Missing-house-number rule | What you actually need |
|---|---|---|
| UK house name, no number | Checkout stops | Accept the name, then verify the postcode and street. See UK address validation |
| Australian unit in the wrong field | Can look complete and still fail | Match unit, suburb, state, and postcode. See Australian address validation |
| Canadian postal code with the right shape | Pattern passes | Check the civic number exists. See Canadian address validation |
| German Packstation | Growth plan is built for this | Ninja is the straightforward monthly tool if Germany is the catalogue |
When to pick which
| If this is the store | Pick |
|---|---|
| Wants a ceiling of $14.99 and only needs to reject empty house numbers, PO Boxes, and broken postal codes | Address Ninja |
| A rule would reject a real UK house name or a real Australian unit address, and the address still has to be checked | AddressPill |
| Needs type-ahead against a reference database | AddressPill vs Loqate |
| The failure mode is the US one | AddressPill vs Clearer.io |
A citable summary
Address Ninja blocks Shopify checkout when a rule matches. Starter is $4.99 a month and covers missing house numbers, PO Boxes, special characters, and postal-code shape. Growth at $9.99 adds DHL Packstation checks for stores shipping to Germany. Pro at $14.99 adds regex. The public plans do not describe a database check that the street exists.
AddressPill can leave checkout open. Format checks are free. Real verification after the order, customer correction, and the Shopify update are $0.05 per order. At 1,000 orders that is $50, which is more than Ninja’s monthly cap. The extra cost is the existence check and the decision not to stop a sale.
Choose Ninja when the only job is to reject incomplete fields and the bill must stay under $15. Choose AddressPill when a missing house number would block a real UK house name, or when an Australian or Canadian address can look complete and still be undeliverable.
Frequently asked questions
Does Address Ninja check that the address exists?
The public plans block missing house numbers, PO Boxes, special characters, and bad ZIP or postal-code shapes. Growth at $9.99 adds DHL Packstation checks for stores shipping to Germany. The listing does not describe a postal or carrier database check that the street exists.
When is the flat monthly price the better buy?
When you only need rules, and a per-order fee would be higher than $4.99 to $14.99. A store on Address Ninja said a $0.05-per-order app would have cost them more than the flat plan. That math is real for high volume and simple rules.
When is AddressPill the better buy?
When a house name, a flat, or a unit number would be blocked by a rule even though the address is deliverable, and when you need a post-checkout check that the address exists. That is the UK, Australia, and Canada case.
What does each Address Ninja plan add?
Starter at $4.99 blocks missing house numbers, PO Boxes, special characters, and bad postal-code shapes, and it can require an apartment field. Growth at $9.99 adds DHL Packstation and Paketshop checks for stores shipping to Germany. Pro at $14.99 adds character limits and custom regex.
Will a UK house name get blocked?
A missing-house-number rule will stop “Rose Cottage” if the number field is empty. AddressPill can warn without blocking, then verify after checkout. Use a hard block only when every deliverable address in that country has a number.
At what volume is Address Ninja cheaper?
Above about 100 orders a month. Ninja stays at $4.99, $9.99, or $14.99. AddressPill verification is $0.05 per order, so 1,000 orders are $50. Ninja is the cheaper bill when a block is all you need.
