AutoPostcode and Postcoder both offer UK address and postcode lookup from Royal Mail PAF data, but AutoPostcode differentiates on transparent per-lookup pricing, fast REST integration and no minimum spend, making it a lower-cost option for most teams.
Which is better, AutoPostcode or Postcoder?
For teams that want predictable per-lookup pricing and a simple REST API, AutoPostcode is the stronger fit. Both draw on the same Royal Mail PAF dataset — roughly 31 million UK delivery-point addresses across about 1.8 million postcodes — so accuracy is comparable, and the decision comes down to cost model and developer experience.
How do AutoPostcode and Postcoder compare?
Here is a side-by-side for typical UK ecommerce and developer setups.

How much does each cost?
AutoPostcode charges a clear per-lookup rate with no minimum spend or expiring credits, so low- and mid-volume sites often pay less than with bundled plans. See the full pricing breakdown to model your volume, and compare the wider market in our postcode lookup API hub.
Is switching from Postcoder difficult?
No. AutoPostcode's UK address validation API returns clean JSON from a single REST call, so most teams swap the endpoint and key in a day. Agencies also weigh alternatives in our best Loqate alternatives guide when consolidating providers across client sites.
When might Postcoder still suit you?
If you already have a Postcoder integration deeply embedded and no pricing pressure, staying put is reasonable. For new builds, cost-sensitive stores or agencies wanting per-site keys, AutoPostcode is designed to be the more flexible, transparent choice.
Frequently asked questions
