Overall verdict

  • I don't have verified information about Codegres.org to confirm its legitimacy, quality, or safety. There is no reliable data in my training set about this specific domain, its ownership, service offerings, or user reputation, so I cannot responsibly claim it is 'good' or 'bad'.

Why this product is good

  • No verifiable company information, reviews, or track record found for this specific domain.
  • Unable to confirm SSL/security practices, business registration, or trust signals typically used to vet a service.
  • Domain names can be repurposed or newly created, making historical reputation data unreliable.
  • Cannot verify feature claims, pricing, or customer support quality without direct, current access to the site.

Recommended for

  • Users should independently verify the site using tools like WHOIS lookup, SSL checker, and Trustpilot/Reddit reviews before use.
  • Not recommended to input sensitive personal or payment information until legitimacy is confirmed.
  • Best suited for cautious research rather than an endorsement at this time.

Questions & Answers

As answered by people managing Postio.co.uk and Codegres.org.

What makes your product unique?

Postio.co.uk's answer

Postio charges only when a lookup returns a result — searching is free. Address, email and phone validation sit behind one API with a single JSON response envelope, so you integrate once rather than stitching three vendors together. Address data comes from Royal Mail's Postcode Address File under a direct licence, not scraped or resold sources. There are no tiers, contracts or minimum spend, and the first 100 lookups need no card.

Which are the primary technologies used for building your product?

Postio.co.uk's answer

A REST API served from edge locations, with official SDKs for JavaScript/Node, Python, Go, PHP, Ruby and .NET, all open source on GitHub. The API is documented by a public OpenAPI specification.

Why should a person choose your product over its competitors?

Postio.co.uk's answer

Pricing is published and pay-as-you-go: 2.2p per address, 1p per email, 1p per phone, billed only on a result. No sales call, no annual contract, no minimum commitment. You can be live in a few minutes with 100 free lookups and no card, and the same API covers all three validation types. For UK addresses specifically, the data is licensed directly from Royal Mail rather than obtained second-hand — which matters after the 2025 High Court ruling on database rights in this market.

How would you describe the primary audience of your product?

Postio.co.uk's answer

Developers and technical teams building UK-facing forms — ecommerce checkouts, signup flows, CRM and logistics systems. Typically small to mid-sized product teams, agencies building for UK clients, and software vendors embedding address lookup in their own product. It suits anyone who wants a UK-accurate API without an enterprise procurement process.

What's the story behind your product?

Postio.co.uk's answer

Postio is a trading name of Onno Group Limited, registered in England & Wales (company no. 08622799). It was built to make Royal Mail PAF-accurate UK validation available on straightforward pay-as-you-go pricing, rather than the contracts and minimum commitments that have been standard in this market. Address, email and phone validation were brought together behind one consistent API so a team can solve all three at once.

Who are some of the biggest customers of your product?

Postio.co.uk's answer

Serving a huge range of customers across the world looking for a blazing fast UK Address AIP product. From bootsrapped entrepreuners to FTSE 250 companies. We serve them all.
