Having to set up identifiers when providing the software for third parties is something we run into often. Doing this in the portal is easy enough, but it’s still tedious. It can be done through a CSV, which is nice, but I think an API link would work well too. For example, if we made a request with an identifier that doesn’t exist, we could get a response that lets us follow up with the identifier and the required details. That would make it easier to automate identifier setup when we onboard a new client. Review collected by and hosted on G2.com.

I like that Postcoder was very quick and easy to integrate, especially since we needed a rapid solution to replace a provider that was no longer available. The API documentation made the process simple. It was also good value for money. Additionally, the initial setup and configuration process was quick and easy, with no complaints. The trial allowed us to do early testing and run it in production to ensure everything worked as expected before seamlessly switching from the trial to the paid plan.

The biggest one for us right now is having to identify third party customers using Postcoder to do with their Royal Mail licensing solution. There's no API for us to sync our customer data with our customer data that needs to be in Postcoder. So it's having to be managed manually, which is not as slick or as convenient as it could be.

We need to ensure that customer e-mail addresses are correct. Most errors are typos so using postcoder to check is fantastic, and avoids the annoying need for people to type their address twice (which isn't foolproof anyway) Review collected by and hosted on G2.com.

On very rare occasions the email validation fails for a valid address, but that's to do with the customer's setup and can be addressed manually. It's VERY rare Review collected by and hosted on G2.com.

I appreciate Postcoder's simple API, which was easy to set up and manage. It's valuable because we haven't had to closely monitor it since the initial installation. The service is cheaper than alternatives, and it does the job perfectly. Their support team is great and any issue we have had was resolved quickly. Review collected by and hosted on G2.com.

I've been using Postcoder for over 5 years now, and it just works without any issues. It's simple to configure, and my sales and delivery team use it daily without even realizing they're using it.
