Questions, answered.
Everything teams ask before signing up - getting started, pricing, compliance and the API. Can't find it? Talk to us.
Getting started
Data Soap is the UK all-in-one data-validation platform. Clean phone numbers, emails and postal addresses, screen against the preference-service registers (TPS, CTPS, MPS) and manage your own suppression lists - all from one account and one balance.
A Home Location Register (HLR) lookup pings the global mobile network to check whether a number is live, what carrier it belongs to, and where it sits - without ringing the phone. Data Soap returns results in around 260ms.
Data Soap is one platform for every check - HLR, MNP, landline, TPS/CTPS, MPS, email and PAF address validation - on one balance. Most competitors force you to use 2–3 separate vendors.
Sign up, grab your API token (or use the drag-and-drop portal), and you can validate your first records in minutes. Most developers are live in under an hour.
No - you get 10 free syntax checks a day with no account, and 100 a day once you add a token. Paid live checks (HLR, landline, email) run on credits and are never rate-limited.
Yes. Use the drag-and-drop portal or the Batch API to validate a whole file. We return a clean file with a reason code on every rejected row.
Pricing & credits
New customers can try the complete platform with £100 of credits for a one-off £4.99 (+VAT). After that it is pay-as-you-go per credit - top up whenever you like. See the pricing page for per-check rates.
One credit = one record checked for one service. Every service draws from the same balance, so you can mix HLR, TPS, email and more in one job. You are only charged for the checks you request.
Beyond ~300,000 records a month we offer bespoke volume pricing - get in touch from the pricing page and we will build a plan around your volumes.
Compliance & the ICO
Yes. Data Soap is operated by Liquid11 Data Limited, a UK company registered with the ICO (ZA128196). We are PCI DSS Level 4 compliant. Everything is UK-built and UK-hosted.
Built in. Screen numbers against TPS, CTPS and MPS, and manage your own Do Not Call (DNC) suppression list from the portal - helping you stay the right side of the ICO (PECR fines now reach £17.5m or 4% of global turnover).
Screen numbers against TPS, CTPS and MPS before you contact them, and manage your own Do Not Call list - helping you avoid ICO complaints. PECR fines now reach £17.5m or 4% of global turnover, whichever is greater.
All processing happens in the UK. Data Soap is operated by Liquid11 Data Limited, based in Suffolk, ICO-registered (ZA128196) and Cyber Essentials Plus certified - so your lists are handled in line with UK GDPR from upload to download.
Using the API
Yes - a synchronous & asynchronous V2 REST API at api.datasoap.co.uk, with a Swagger sandbox, a C# SDK, and native integrations for Zapier, WordPress, Gravity Forms, WooCommerce and more. There is a free tier of 10 syntax checks a day (100 with a token).
Pass any combination of Auto, Hlr, Mnp, Tps, Landline, Email and Syntax in the checks array.
Mobile & Email (Real-Time): HLR and email checks are queried live and in real-time against the networks and mail servers that own the data.
TPS, CTPS, MPS & PAF (Updated Daily): Official suppression lists and address registries are updated every single day, so you are always working with the latest files.
Landline Validation: While landlines cannot be queried live on the network, we provide an enhanced validation service fed by multiple trusted data sources to give you the highest possible accuracy.
Zapier, Unbounce, WordPress, Contact Form 7, Elementor Pro, Gravity Forms, WooCommerce, WP Forms and Growform - plus the REST API and C# SDK for anything custom.
