The Most Challenging Identity Documents to Verify Globally, According to Regula
RESTON, Va., April 21, 2026 (GLOBE NEWSWIRE) -- Regula, a global developer of identity verification solutions, released a new analysis of the world’s most challenging identity documents to verify digitally, finding that IDs using Arabic, Chinese, Japanese, and South Asian scripts remain among the hardest for automated systems to process accurately. The findings highlight growing risks for global onboarding, fraud prevention, and customer access as businesses automate identity checks.
The most complex non-Latin scripts in identity verification
In practice, the most challenging IDs combine three factors: high global usage, frequent appearance in verification flows, and a complex script, leading to a high likelihood of OCR (optical character recognition), parsing, or matching errors.
Identity documents in non-Latin scripts consistently rank among the most challenging. Among them are: IDs in Arabic, Chinese, Japanese, and South Asian scripts (used in India, Sri Lanka, Thailand, Myanmar, Laos, etc.).
Some of the most common failure points include:
Where verification fails
The complexity of non-Latin IDs verification comes from how personal data is structured and transformed across systems — not just from the scripts themselves. In real-world workflows, identity verification rarely relies on a single data source. Systems must reconcile information across:
Even when each element is technically correct, differences in spelling, formatting, or document structure can lead to mismatches. This leads to three critical business risks:
In other words, businesses are not just missing fraud — in some cases, they are approving identities that don’t hold together.
“Today’s challenge in global identity verification is interpreting IDs consistently across languages and formats. In non-Latin scenarios, even valid documents can fail checks because the same identity is represented differently across data sources. That’s why effective verification requires more than OCR — it depends on combining document knowledge, transliteration, and cross-source validation to build a consistent, reliable identity profile,” says Ihar Kliashchou, Chief Technology Officer at Regula.
A layered approach to non-Latin document verification
To address these challenges, modern identity verification requires more than OCR. It depends on a layered approach that includes:
Regula identity verification solutions are designed around this approach. They combine document type recognition, OCR, parsing, transliteration, and cross-checks across multiple data sources — supported by a proprietary ID template database of over 16,000 document templates from 254 countries and territories.
By integrating these capabilities into a single system, Regula enables businesses to reduce false mismatches, minimize manual review, and maintain consistent verification accuracy across diverse document types and scripts.
