Can document data extraction handle documents from every country?

No solution genuinely handles literally every document type from every country, and it's worth being skeptical of any vendor claiming absolute universal coverage. What's realistic, and what the more established vendors in this space actually offer, is very broad coverage, commonly spanning well over a hundred countries and, depending on how granularly document variants are counted, thousands of distinct document templates when you factor in different document types (passport, national ID, driver's license) and different generations of each as countries redesign their documents over time.

Coverage breadth matters a lot in practice, particularly for businesses serving an internationally diverse customer base. A company processing IDs primarily from a handful of countries has very different requirements than a global travel platform or international bank that might encounter documents from nearly anywhere in the world.

Asking a vendor specifically which countries and document types they support, rather than accepting a general "we support hundreds of documents" claim, is a reasonable and useful step before committing to a solution.

New documents are issued constantly, as countries redesign IDs, add new security features, or introduce entirely new document categories, which means document coverage isn't a one-time achievement but an ongoing maintenance effort. Vendors with dedicated teams tracking new document releases and continuously expanding their template libraries tend to keep pace with this better than those treating document coverage as a fixed, static list.

It's also worth distinguishing between "supported" in the sense of having a dedicated template with full field-level extraction, versus a more basic fallback that can extract MRZ data (if present) using the standardized ICAO format even without a document-specific visual zone template. The latter can provide partial coverage for a document the vendor hasn't specifically built support for yet, though it won't extract visual-zone-only fields like an address.

ScanDoc maintains coverage across a broad range of countries and document types, with an in-house team tracking new document releases so the template library keeps expanding rather than remaining static, though as with any vendor, it's worth confirming coverage for your specific target countries and document types directly rather than assuming universal support.
