Postcoder uses credits

Each request you make uses credits. For example, an address lookup uses 2 credits and an email validation uses 1.2 credits. You can add credits to your account with a pay-as-you-go credit pack or monthly plan. Use the credit calculator below to estimate how many credits you'll need.

We're here to help

We provide free support to customers and to those interested in using Postcoder. From pricing questions to technical queries, we're ready to help.

Frequently asked questions

How long do credits last?For all of our credit packs, your credits will last for 12 months. For our monthly plans, your credit balance will be updated at the start of each month; unused credits are not carried over to the next month.
Can I buy a one-off credit pack?Yes. When you buy a credit pack, there's no obligation to buy another one.
Can my credits be used for all types of request?Yes, your credits can be used for any Postcoder request. For example you could use them for both address lookup and mobile validation requests. You don't need to have different accounts or separate credit balances for different requests.
Why isn't one credit equivalent to one lookup?Postcoder offers a variety of different requests, all of which incur different costs. This is why we can't equate one credit to one lookup. Please see the credit costs page in the Postcoder documentation for a detailed list.
What happens when my credits run low?

Postcoder will automatically notify you via email when your credit balance runs low. To avoid running out of credits you can:

  • Enable auto top-up when you purchase a credit pack; or
  • Buy another credit pack when Postcoder emails you to say your credits are running low; or
  • Check how many credits you have by logging into your account or by using the status endpoint; or
  • Consider setting up a monthly plan instead.
I want to buy a monthly plan, but what happens if my usage changes?You can change or cancel your plan every 30 days. Any additional use is simply added to your next month's bill.
Does pricing include Multiple Residence data?Yes, our pricing for UK address lookup always includes Royal Mail's Multiple Residence data as standard. This makes it excellent value.
Why are Irish address lookups more expensive than UK address lookups?The price difference reflects the different data licence fees that we pay to Eircode and Royal Mail on your behalf.
Why is the recommended monthly plan or credit pack too small or large?The credit calculator recommends the most cost effective option for your expected usage.

Monthly plans - the most cost-effective option may be to select a smaller monthly plan and pay for any additional credits on top (these are automatically added to next month's bill), or to upgrade to a larger monthly plan that you don't completely use each month.

Credit packs - the most cost-effective option may be to buy a smaller credit pack more than once (you can use auto top-up if you wish), or to buy a larger credit pack that you don't completely use within 12 months.
