Our Story
PostcodeBase was founded in 2015 with a simple goal: make accurate postal code data accessible to businesses of all sizes. We noticed that while large corporations had access to expensive postal databases, small businesses and developers struggled to find reliable, affordable alternatives.
Over the years, we've grown from a small team of data enthusiasts to a trusted provider serving over 10,000 businesses worldwide. Our customers range from e-commerce platforms and logistics companies to government agencies and tech startups.
What sets us apart is our commitment to data quality and customer service. We invest deeply in data verification processes, maintain direct relationships with postal authorities, and provide comprehensive support to ensure our customers get the most value from our products.
Today, we continue to expand our coverage, improve our data accuracy, and develop new tools to help businesses leverage location intelligence for growth.
