What do you like best about Postcoder?

We've been using Postcoder.com for many years and have had a fantastic experience. Originally we just used it for address lookup, the platform has evolved significantly, offering much more than just postcode validation.

The additional features help create a more detailed profile of customers and verify key details, improving data accuracy and customer insights. The service is fast, efficient, and integrates seamlessly into our systems. Their continued innovation and excellent support make them a valuable partner. If you're looking for address verification and customer data enrichment solution, Postcoder.com is a top choice. Highly recommended! Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

It would be great if the pricing on other items was for rounded credit not like 2.4 credits for a mobile look up. other than that its great. Review collected by and hosted on G2.com.

What problems is Postcoder solving and how is that benefiting you?

quick address look up, good an easy integration into our systems Review collected by and hosted on G2.com.

Response from Rachel Potter of Postcoder

Hi, thanks so much for your positive feedback; we're really pleased you're taking advantage of some of our additional features and that you have found our support to be as helpful as we intend it to be. We appreciate the comment regarding the credit pricing; we did consider rounding certain credits to the nearest whole or half credit, but by keeping them rounded to the nearest decimal place it allows us to keep our prices as cost-effective for our customers as possible. We will bear it in mind for future price changes though!

What do you like best about Postcoder?

We tried a number of different address lookup services before deciding to go with Postcoder.

Not only did we receive the most accurate address and location data from postcoder, but the help we received from the support team (especially Kit) and the easy to navigate admin portal made it an easy decision.

The API is fast to respond to requests. We haven't had any issues since switching to Postcoder Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

If I had to point out a downside, it would be that we didn't have enough credits to for our testing, so we had to request more. However the support team was quick to fix this issue for us Review collected by and hosted on G2.com.

What problems is Postcoder solving and how is that benefiting you?

Response from Rachel Potter of Postcoder

Hi, we're delighted to hear that you're pleased with the accuracy of our data and the level of service we provide. And thank you for your feedback about the credits available for testing; we will take that into consideration when we review this process.

What do you like best about Postcoder?

Works well, response is fast and in at least 5 years of use I think there has only been 1 issue which prevented postcode lookups from the service.

UI is clear and easy to use, and recently been improved.

There is also an api endpoint which you can connect your moniotoring system to so you can track remaining credits along with your other key system metrics.

Lots of extra info like latitude, longtittude, udprn, etc. Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

1. The json endpoint for monitoring required contacting suport to find out about, after an incident when we ran out of credits. Docs have been updated, it's part of the /status request.

2. When you need to change payment method you have to purchase a new pack and set it up as auto top up, and then delete the original auto top package - rather than just being able to update you card details.

3. Not sure if there is a caching mechanism meaning that if you are not proactive a single user, or bad bit of code, can burn your credits down quite a bit on the same lookup.

4. Some postcodes have more addresses than the max response, another little gotcha. Be sure to check for the paging key which only appears when this is the case! Review collected by and hosted on G2.com.

What problems is Postcoder solving and how is that benefiting you?

Finding addresses for our customers based on postcode.

Locating a user against GIS data map to identify client region (built but not in use due to lack of GIS data files from a number of business partners) Review collected by and hosted on G2.com.

Response from Jasmine Robinson Madden of Postcoder

Hi Stephen, thank you for your review and taking the time to share your thoughts. Glad to hear you find the UI easy to use and the response fast, and that you've seen improvement over the last 5 years. We're always working to improve our documentation too, and we take all user feedback into account. I've included a link below to the pagination section of our docs in case anyone else has a similar issue. We are also currently working to simplify the process of updating payment methods - I appreciate it's a current pain point! Many thanks again for your review.

What do you like best about Postcoder?

The most important reason to use any address, bank or email checking service is it's reliability in giving you the correct answer. We have found Postcoderweb to be the gold standrad for this.

We needed to integrate Postcoderweb and othere APIs into our Oracle Apex based product (verify-it.co.uk) and found that Postcoderweb made that easy for us to do. Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

Nothing really, everything works well. When we have had issues we get quick answers from their helpdesk. Review collected by and hosted on G2.com.

What do you like best about Postcoder?

Simple to integrate, clean verified addresses, easy to use for our end users. Helpful and quick responses from the support team. Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

Certain datasets like the Eircode directory have limitations as to their trial usage that limits the amount of time development teams can have to integrate and test. There really should be a means to have unlimited development access to data and APIs without credit usage for those that have a production license. Review collected by and hosted on G2.com.

Validated address input and simplified customer journeys Review collected by and hosted on G2.com.

Response from Jasmine Robinson Madden of Postcoder

We're glad to hear that you find Postcoder simple to integrate and easy to use for your end users. We strive to provide helpful and quick support to all our customers. We do understand your concerns about limitations on trial usage for certain datasets. Some datasets have licensing requirements that prevent us from offering unlimited trial or development usage. We will take your feedback on this into consideration as we continue to improve our services, particularly for users in the development phase. Many thanks for taking the time to leave a review.

What do you like best about Postcoder?

Had really good customer support. After starting the trial I was contacted to understand our use case but was not pushed for a sale. We didn't need any support as the API documentation was sufficiently detailed. Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

I would prefer a more straightforward per lookup billing to the credit based system. Review collected by and hosted on G2.com.

What problems is Postcoder solving and how is that benefiting you?

Postcoder has been integrated with our ERP platform to give customer address lookups. Helpful in ensuring we only attempt to ship to accurate and valid addresses. Review collected by and hosted on G2.com.

What do you like best about Postcoder?

Easy to use API that's fast and reliable, reasonable pricing. Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

Email alerts for increases in usage can be overzealous (e.g. alert because a site has used 10 lookups in one day instead of the usual 1 or 2 lookups). Review collected by and hosted on G2.com.
