How it works
Three steps. Two minutes. One plugin.
1
Create an account
Sign up and get 100 free lookups to test with. No card required.
2
Install the WooCommerce plugin
One click from your WordPress dashboard. Works with classic checkout and block-based checkout out of the box.
3
Paste your API key
That's it. Your customers start seeing address suggestions as they type — and postcode search works too: enter a postcode, pick an address from the dropdown.
What you get
Everything a UK store needs. Nothing it doesn’t.
Postcode lookup and address autocomplete
Both search modes in one API. Customers can type a postcode and pick from a list, or start typing their address and get instant suggestions. Either way, the right address fills the form.
Royal Mail PAF data, updated monthly
Every lookup hits the Postcode Address File — over 30 million UK addresses. We're a licensed Royal Mail PAF Solutions Provider, verifiable directly with Royal Mail.
Drop-in replacement for getAddress.io and Loqate
Migrating from a previous provider? Our API accepts the same request formats. Change the endpoint, swap the key, and your existing integration keeps working — with step-by-step guides for both.
Your checkout never breaks
If your credits run out, the address field falls back to manual entry, so your checkout keeps taking orders. No HTTP 429s, no silent failures.

“Per lookup” is the price of one API request. Because checkout autocomplete searches as the customer types, a completed address search uses about 2–4 lookups — see how we size packs.

Migrating from getAddress.io?
A drop-in replacement, ready today.
In October 2025 the High Court of England and Wales held that the address data used by the getAddress.io service infringes Royal Mail’s and IDDQD Limited’s database rights and copyright. getAddress.io’s own notice warns that customers using that data may be affected too. SnapAddress is a properly licensed Royal Mail PAF Solutions Provider and a drop-in replacement.
- 1Install the SnapAddress plugin from WordPress.org
- 2Remove the old getAddress.io plugin
- 3Paste your SnapAddress API key
The plugin auto-detects your checkout fields — the same postcode dropdown your customers are used to. Takes about two minutes.

Same data. A fraction of the price.
Loqate works fine — but if you’re a small WooCommerce store paying enterprise rates for UK-only address lookup, you’re probably overpaying. SnapAddress uses the same Royal Mail PAF data and costs a fraction of the price. Our API supports Loqate’s request format: swap the endpoint and key, and your integration keeps working.

Not on WooCommerce? Use the API directly.
SnapAddress is a REST API — the WooCommerce plugin is just one way in. Add postcode lookup and address autocomplete to any stack in a few lines: clean JSON responses, drop-in compatible with the getAddress.io and Loqate request formats.

Questions
Common questions
Is this the same data as Ideal Postcodes and Loqate?+
Yes. Every UK address lookup provider uses Royal Mail's Postcode Address File — over 30 million addresses, updated regularly. The difference is price, integration quality, and how much hassle you have to deal with.
Do I need a separate Royal Mail licence?+
No. Your PAF licence is covered by our Solutions Provider agreement. You don't need to register with Royal Mail or pay them directly.
Does it work with WooCommerce block checkout?+
Yes. The plugin supports both classic and block-based WooCommerce checkout. No configuration needed.
What happens when my credits run out?+
Your checkout keeps working: the address lookup field falls back to manual entry, so orders still go through.
Can I use this on multiple sites?+
Yes. One API key works across multiple domains. Your lookups are deducted from the same balance.
How many lookups does a checkout search use?+
A lookup is one API request. Because the checkout field searches as your customer types, a typical address search uses two to four lookups - a few suggestions as they type, then one retrieval when they pick. That's not a markup: every autocomplete query is a licensed Royal Mail PAF request, so a completed search costs a few. We'd rather tell you up front than have you find it in your balance — and customers who type manually or reuse a saved address don't trigger it at all.
Do credits expire?+
Credits are valid for 12 months from purchase. This is a Royal Mail PAF licensing requirement that every licensed provider works under. A low-volume store gets a couple of months from a 500-credit Starter pack, well inside that window; busier stores size up.
Do you offer refunds?+
Credits are non-refundable once purchased — that's why we give you 100 free lookups up front, so you can be sure SnapAddress fits before you pay. We'll always put right genuine billing errors.
