The Hidden Challenge in Data Cleaning & Matching: Validating Global Identifiers
Running a business across borders means dealing with a maze of structured identifiers – VAT numbers, IBANs, NHS numbers, ISBNs, company codes, and more. On the surface, these fields may look correct, but deeper validation often tells a different story.
Incorrect identifiers impact everything downstream – profiling, cleansing, matching, onboarding, and compliance.
That’s where MatchX’s Validation Library comes in – a powerful engine that makes global data clean and usable by validating over 200+ identifiers from around the world using real logic, not just patterns.
Why Clean, Validated Data Matters?
Messy or invalid data—whether it’s a mistyped VAT number, an incorrect IBAN, or a wrongly formatted NHS number—can cause:
- Duplicate customer/vendor records
- Failed transactions or fund transfers
- Compliance violations (HMRC, NHS, EU, etc.)
- Missed fraud detection
- Delays in onboarding and processing
- Hours of manual rework after ingestion
Whether you’re an online store, a healthcare provider, a bank, or a public-sector body, you need accurate, validated identifiers from day one.
What Makes MatchX Validation Library Stand Out?
Most tools stop at format checks—like length or regex patterns. MatchX goes several steps further, performing logic-based, country-specific validation using control digits, checksum algorithms, and regional rules.
Key features include:
- Global Coverage: Supports 200+ formats across 100+ countries
- VAT (EU), GST, TIN, ABN, CIN
- IBAN, SWIFT/BIC
- NHS and NI (UK)
- ISBN, EAN, GTIN, and more
- Real-World Validation Logic: Applies actual rules and logic per identifier—not just surface pattern checks.
- Fewer Errors, Faster Onboarding: Catches invalid IDs before they reach downstream systems.
- Built-in Intelligence:
- Validation is fully integrated into the MatchX pipeline:
- Ingestion → Validation → Profiling → Cleansing → Matching
- Accessible for All Teams: No technical expertise needed. Available via intuitive UI and simple APIs.
How It Works?
Using MatchX is as easy as 1-2-3:
- Input your data — e.g., a VAT number, IBAN, or NHS number.
- MatchX validates it using country and context-specific rules.
- Get instant results — “Valid” or clear fix suggestions with reasons.
This ensures you only work with clean, reliable data from the start.
Real-World Wins Across Industries
MatchX’s Validation Library powers organizations across industries:
- E-commerce: Verifies VAT and IBAN data to reduce payment failures.
- Healthcare: Checks NHS and NI numbers to maintain patient data integrity.
- Publishing & Logistics: Validates ISBNs, EANs, and GTINs for catalog accuracy.
- Public Sector & Finance: Ensures compliance with UK and global identifier standards.
Why We Built It: Analyst Insight?
As a Business Analyst working across international and regulated data sets, I found that existing tools often failed to catch real-world validation issues. That’s why our team built our validator library as a core feature inside MatchX—not just a utility, but an essential step in the data quality lifecycle.
What Sets MatchX Apart from Others?
Most solutions treat validation as a checkbox. MatchX treats it as a first-class citizen in your data pipeline.
