⚡ Why UzKit?

Building applications for the Uzbekistan market requires dealing with local payment systems, phone formatting, invoice receipt generation, and legal document validations. UzKit provides a clean, battle-tested, 100% null-safe suite of utilities so you never have to reinvent the wheel.

• 💳 Bank Card Recognition: Instantly detects Uzcard, Humo, Visa, Mastercard, UnionPay, and Mir cards with auto-formatting, masking, and Luhn checksum validation.
• 📞 Phone & Mobile Operator: Formats +998 (xx) xxx-xx-xx and detects Beeline, Ucell, Mobiuz, Uztelecom, Humans, and Perfectum by network code.
• 💰 Money to Words in Uzbek: Converts numerical amounts up to trillions into written Uzbek words ("bir million to'rt yuz ellik ming so'm") in both Latin and Cyrillic alphabets with tiyin support.
• 🆔 Official Identity Verification:
  • JShShIR (PINFL): 14-digit official State Tax Committee checksum verification.
  • Passport & ID-Cards: Formatting and pattern validation (AA 1234567).
  • STIR (INN): 9-digit Taxpayer Identification Number validation.
